使用Javascript / jQuery下载文件


357

在这里指定了非常相似的要求。

在以下情况下,我需要让用户的浏览器手动开始下载 $('a#someID').click();

但是我无法使用该window.href方法,因为它会将当前页面的内容替换为您尝试下载的文件。

相反,我想在新窗口/选项卡中打开下载。这怎么可能?


我在相关问题中尝试了许多答案,这是确定的答案
Basj

设置window.location.href对我有用。窗口内容也不会改变。我假设您使用了错误的contentType?

使用不可见的<iframe>

<iframe id="my_iframe" style="display:none;"></iframe>
<script>
function Download(url) {
    document.getElementById('my_iframe').src = url;
};
</script>

要强制浏览器下载本来可以呈现的文件(例如HTML或文本文件),则需要服务器将文件的MIME类型设置为无意义的值,例如application/x-please-download-me或另外application/octet-stream,用于任意二进制数据。

如果只想在新标签页中打开它,则唯一的方法是让用户单击其target属性设置为的链接_blank

在jQuery中:

$('a#someID').attr({target: '_blank', 
                    href  : 'http://localhost/directory/file.pdf'});

只要单击该链接,它将在新的选项卡/窗口中下载文件。

网页无法自动打开新标签页。要强制浏览器下载,请让服务器发送带有废话MIME类型的pdf文件,例如application / x-please-download-me

做得很好!很好地解决问题。但是,您可能要使用:,iframe.style.display = 'none'; 因为这将完全隐藏iframe。您当前的实现将使iframe不可见,但iframe仍将占据页面底部的空间,从而导致额外的空白。

它“半”对我有用。我创建了以下简单的测试html:<html> <body> <iframe src =“ fileurl”> </ iframe> </ body> </ html>,它确实已下载,但是在chrome控制台中,我看到了下载被“取消”并显示为红色。这是较大的移动Web应用程序的一部分,并且被取消的事实破坏了该应用程序,因为它引起了一般的Web故障。可以解决吗?

不错的摘要。但是,设置无意义的事物类型有点令人不安。要要求浏览器下载它可以呈现的文件,请使用以下标头:(Content-Disposition: attachment; filename="downloaded.pdf"当然,您可以根据需要自定义文件名)。

如何在没有服务器的情况下强制下载?因此,只是带有一些javascript的html页面。

2019现代浏览器更新

这是我现在建议的一些警告:

  • 需要相对较新的浏览器
  • 如果期望文件很大,则您可能应该执行与原始方法(iframe和Cookie)类似的操作,因为以下某些操作可能会消耗系统内存,至少与正在下载的文件和/或其他有趣的CPU一样大。副作用。

fetch('https://jsonplaceholder.typicode.com/todos/1')
  .then(resp => resp.blob())
  .then(blob => {
    const url = window.URL.createObjectURL(blob);
    const a = document.createElement('a');
    a.style.display = 'none';
    a.href = url;
    // the filename you want
    a.download = 'todo-1.json';
    document.body.appendChild(a);
    a.click();
    window.URL.revokeObjectURL(url);
    alert('your file has downloaded!'); // or you know, something with better UX...
  })
  .catch(() => alert('oh no!'));

2012年基于jQuery / iframe / cookie的原始方法

我创建了jQuery File Download插件Demo)(GitHub),它也可以帮助您解决问题。它与iframe的工作方式非常相似,但具有一些很酷的功能,我发现它们非常方便:

  • 易于安装且外观精美(jQuery UI对话框,但不是必需的),所有内容也都经过了测试

  • 用户永远不会离开从其启动文件下载的同一页面。此功能对于现代Web应用程序变得至关重要

  • successCallback和failCallback函数使您可以清楚了解两种情况下用户看到的内容

  • 结合jQuery UI,开发人员可以轻松地向用户显示模式文件,告知用户正在下载文件,可以在下载开始后解散该模式,甚至可以以友好的方式通知用户发生了错误。有关此示例,请参见演示。希望这对某人有帮助!

这是一个使用带有Promise 的插件的简单用例演示。该演示页包含了许多其他“更好的UX”的例子也是如此。

$.fileDownload('some/file.pdf')
    .done(function () { alert('File download a success!'); })
    .fail(function () { alert('File download failed!'); });

@JohnCulviner:我可以用您的post方法发送json数据吗?我尝试了一下,但失败了。你能不能给我的样品
Saravanan

是否可以将参数传递给调用?假设我需要传递一些ID,以便服务器生成希望下载的文件,该怎么办?谢谢

已完成100次。感谢您的宝贵时间-这确实很有价值。考虑建立一个PayPal链接进行捐赠。我会捐赠的。
Stephan Schinkel

我尝试了,但是回调从未执行。即使服务返回错误,该插件也只会在新选项卡中打开服务响应。我不希望应用程序在抛出错误时打开新选项卡并显示服务响应。我什至添加了cookie来指示文件下载成功与失败的对与错,但响应仍在新选项卡中打开。任何解决此问题的方法。

@MarkAmery也可以像其他答案一样工作。该方法(AFAIK)无法为您提供下载开始时间,下载完成时间以及是否出错的方便反馈。我可以将其添加到“解雇”选项的答案中。此外,[download]属性也不允许POST或任何其他奇异的东西。

function downloadURI(uri, name) 
{
    var link = document.createElement("a");
    // If you don't know the name or want to use
    // the webserver default set name = ''
    link.setAttribute('download', name);
    link.href = uri;
    document.body.appendChild(link);

对我而言,这将是完美的,但它在Firefox上也不起作用。任何的想法?

caniuse.com/#feat=download中所述,这仅适用于最近Firefox和Chrome版本上的同源链接。因此,如果您的链接指向另一个域,则暂时无法在任何地方使用。

为了使其能够在Firefox上运行,请document.body.appendChild(link)在单击之前进行操作,然后单击link.remove()以防止污染DOM。

您也可以link.download = ""保留它的原始文件名并避免设置一个文件名。

令我惊讶的是,没有多少人知道元素的下载属性。请帮助传播有关它的消息!您可以有一个隐藏的html链接,然后对其进行伪造单击。如果html链接具有download属性,则无论如何,它都会下载文件,而不是查看文件。这是代码。如果可以找到猫的图片,它将下载。

document.getElementById('download').click();
<a href="https://docs.google.com/uc?id=0B0jH18Lft7ypSmRjdWg1c082Y2M" download id="download" hidden></a>

注意:并非所有浏览器都支持此功能:http : //www.w3schools.com/tags/att_a_download.asp

我建议使用download属性进行下载,而不是jQuery的:

<a href="your_link" download> file_name </a>

这将下载您的文件,而无需打开它。

我认为,这是对问题的正确答案。如果您必须支持较旧的浏览器并需要解决方法,则其他答案很有意义。

如果您已经在使用jQuery,则可以尝试使用它来生成一个较小的摘录
。答案是jQuery版本的Andrew:

var $idown;  // Keep it outside of the function, so it's initialized once.
downloadURL : function(url) {
  if ($idown) {
    $idown.attr('src',url);
  } else {
    $idown = $('<iframe>', { id:'idown', src:url }).hide().appendTo('body');
  }
},
//... How to use it:
downloadURL('http://whatever.com/file.pdf');

仅供参考,有人建议(通过编辑我的帖子)添加$ idown.attr('src',url); 首次创建iframe之后。我认为不需要。它已经在创建步骤中设置了“ src:url”。
corbacho 2012年

还要评论一下,最后我没有使用此解决方案,因为当您在https网站中时,IE 9不喜欢动态创建指向http://的iframe。我不得不使用“ window.location.href”,该解决方案也带来一些不便
corbacho 2012年

在最新的Chrome(24)中,“ if($ idown)”部分对我不起作用,但是创建了无数个iframe却没有。也许是因为我想同时下载12个东西?

if声明确实应该是:if( $idown && $idown.length > 0 )

在Chrome中无法执行任何操作
jjxtra 2014年

11

适用于Chrome,Firefox和IE8及更高版本。

var link=document.createElement('a');
document.body.appendChild(link);
link.href=url ;
link.click();

如果您不将链接附加到DOM,这也将起作用。
约翰尼·卡尔

除非从服务器返回的标头指示执行其他操作,否则这将仅导航到url,而不是从其中下载。
Mark Amery

使用一个简单的例子 iframe

function downloadURL(url) {
    var hiddenIFrameID = 'hiddenDownloader',
        iframe = document.getElementById(hiddenIFrameID);
    if (iframe === null) {
        iframe = document.createElement('iframe');
        iframe.id = hiddenIFrameID;
        iframe.style.display = 'none';
        document.body.appendChild(iframe);
    }
    iframe.src = url;
};

然后,只需在需要的地方调用该函数即可:

downloadURL('path/to/my/file');


10

如果不需要浏览其他页面,这可能会有所帮助。这是基本的javascript函数,因此可以在Javascript后端的任何平台中使用

window.location.assign('any url or file path')

如果您可以自己设置contentType,这可能是最简单的解决方案。我将其用作:window.location.href = downloadFileUrl;

如果管理员不希望向用户显示URL,那么?

仅七年后,这里出现了一种使用表单而不是iframe或链接的jQuery解决方案:

$('<form></form>')
     .attr('action', filePath)
     .appendTo('body').submit().remove();

我已经测试过

  • 铬55
  • Firefox 50
  • 边缘IE8-10
  • iOS 10(Safari / Chrome)
  • Android Chrome浏览器

如果有人知道此解决方案有任何缺点,我将非常高兴听到它们的消息。


完整演示:

<html>
<head><script src="https://code.jquery.com/jquery-1.11.3.js"></script></head>
<body>
<script>
    var filePath = window.prompt("Enter a file URL","http://jqueryui.com/resources/download/jquery-ui-1.12.1.zip");
    $('<form></form>').attr('action', filePath).appendTo('body').submit().remove();
</script>
</body>
</html>

7
如果您filePath有一个查询字符串,这将不起作用,因为提交表单将覆盖action属性中的查询字符串。
Bobort

1
我通过在表单中​​添加输入来解决此问题:var authInput = $("<input>").attr("type", "hidden").attr("name", "myQsKey").val('MyQsValue'); $('<form></form>') .attr('action', filePath) .append($(authInput)) .appendTo('body').submit().remove();这等效filepath?myQsKey=myValue
acessing

这也将关闭websocket。
radu122

这看起来像一个非常复杂的方式来设置window.locationfilePath。只是window.location = filePath;会做同样的事情。
伊沃·史密斯

不管是否有一个缺点这种解决方案本身,您没有提供任何上攻使用这种过度的链接。(还有一个缺点:download无论服务器返回什么标头,都不能通过这种方式使用该属性告诉浏览器您要下载,您可以使用一个a元素来完成。)
Mark Amery

我不知道问题是否太老了,但是只要下载的哑剧类型正确(例如zip存档),就可以将window.location设置为下载网址。

var download = function(downloadURL) {

   location = downloadURL;

});

download('http://example.com/archive.zip'); //correct usage
download('http://example.com/page.html'); //DON'T

5

我最终使用了以下代码段,该代码段可在大多数浏览器中使用,但未在IE中进行测试。

let data = JSON.stringify([{email: "test@domain.com", name: "test"}, {email: "anothertest@example.com", name: "anothertest"}]);

let type = "application/json", name = "testfile.json";
downloader(data, type, name)

function downloader(data, type, name) {
	let blob = new Blob([data], {type});
	let url = window.URL.createObjectURL(blob);
	downloadURI(url, name);
	window.URL.revokeObjectURL(url);
}

function downloadURI(uri, name) {
    let link = document.createElement("a");
    link.download = name;
    link.href = uri;
    link.click();
}

更新资料

function downloadURI(uri, name) {
    let link = document.createElement("a");
    link.download = name;
    link.href = uri;
    link.click();
}

function downloader(data, type, name) {
    let blob = new Blob([data], {type});
    let url = window.URL.createObjectURL(blob);
    downloadURI(url, name);
    window.URL.revokeObjectURL(url);
}

MouseEvent在这里使用而不是一直使用有click什么意义?为什么要在单击链接之前将链接附加到文档?相对于stackoverflow.com/a/23013574/1709587中显示的更简单的方法,它可能具有优势,但是如果是这样,这里就不做解释了。
Mark Amery

我发布这个答案已经有一段时间了。我不记得那些不必要的代码行背后是否有任何原因。
Abk

为了改善Imagine Breaker的答案,FF&IE支持此功能:

var evt = document.createEvent("MouseEvents");
evt.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);

function downloadURI(uri, name) {
    var link = document.createElement("a");
    link.download = name;
    link.href = uri;
    link.dispatchEvent(evt);
}

换句话说,只需使用dispatchEvent函数而不是click();


这有何改进?这似乎只是做同一件事的一种更复杂的方法。

也许只是让您的javascript打开一个页面即可下载文件,例如将下载链接拖到新标签页时:

Window.open("https://www.MyServer.
Org/downloads/ardiuno/WgiWho=?:8080")

在打开的窗口中打开自动关闭的下载页面。

以下是用于FireFox,Chrome和IE的下载数据的最完整,最有效(经过测试)的代码。假设数据位于texarea字段中,其id ='textarea_area'文件名是将下载数据的文件的名称。

function download(filename) {
    if (typeof filename==='undefined') filename = ""; // default
    value = document.getElementById('textarea_area').value;

    filetype="text/*";
    extension=filename.substring(filename.lastIndexOf("."));
    for (var i = 0; i < extToMIME.length; i++) {
        if (extToMIME[i][0].localeCompare(extension)==0) {
            filetype=extToMIME[i][1];
            break;
        }
    }


    var pom = document.createElement('a');
    pom.setAttribute('href', 'data: '+filetype+';charset=utf-8,' + '\ufeff' + encodeURIComponent(value)); // Added BOM too
    pom.setAttribute('download', filename);


    if (document.createEvent) {
        if (navigator.userAgent.indexOf('MSIE') !== -1 || navigator.appVersion.indexOf('Trident/') > 0) { // IE
            blobObject = new Blob(['\ufeff'+value]);
            window.navigator.msSaveBlob(blobObject, filename);
        } else { // FF, Chrome
            var event = document.createEvent('MouseEvents');
            event.initEvent('click', true, true);
            pom.dispatchEvent(event);
        }
    } else if( document.createEventObject ) { // Have No Idea
        var evObj = document.createEventObject();
        pom.fireEvent( 'onclick' , evObj );
    } else { // For Any Case
        pom.click();
    }

}

然后打电话

<a href="javascript:download();">Download</a>

对于下载启动。

可以为下载对话框设置正确的MIME类型的数组可以是:

对我来说,这在chrome v72中可以正常测试

function down_file(url,name){
var a = $("<a>")
    .attr("href", url)
    .attr("download", name)
    .appendTo("body");
a[0].click();
a.remove();
}

down_file('https://www.useotools.com/uploads/nulogo[1].png','logo.png')

这与几年前Imagine Breaker的答案中所示的方法相同,但是还需要使用jQuery。

使用FORM标记的效果很好,因为它可以在任何地方使用,而且您不必在服务器上临时创建文件。该方法是这样的。

在客户端(页面HTML)上,您将创建一个不可见的表单,如下所示

<form method="POST" action="/download.php" target="_blank" id="downloadForm">
    <input type="hidden" name="data" id="csv">
</form>

然后,您将此Javascript代码添加到按钮中:

$('#button').click(function() {
     $('#csv').val('---your data---');
     $('#downloadForm').submit();
}

在服务器端,您在以下PHP代码中download.php

<?php
header('Content-Type: text/csv');
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=out.csv');
header('Content-Transfer-Encoding: binary');
header('Connection: Keep-Alive');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . strlen($data));

echo $_REQUEST['data'];
exit();

您甚至可以像这样创建数据的zip文件:

<?php

$file = tempnam("tmp", "zip");

$zip = new ZipArchive();
$zip->open($file, ZipArchive::OVERWRITE);
$zip->addFromString('test.csv', $_REQUEST['data']);
$zip->close();

header('Content-Type: application/zip');
header('Content-Length: ' . filesize($file));
header('Content-Disposition: attachment; filename="file.zip"');
readfile($file);
unlink($file); 

最好的部分是,由于所有内容都是动态创建和销毁的,因此不会在服务器上保留任何残留文件!

hitesh在13年12月30日提交的答案确实有效。只需稍作调整即可:

PHP文件可以自行调用。换句话说,只需创建一个名为saveAs.php的文件,并将此代码放入其中...

        <a href="saveAs.php?file_source=YourDataFile.pdf">Download pdf here</a>

    <?php
        if (isset($_GET['file_source'])) {
            $fullPath = $_GET['file_source'];
            if($fullPath) {
                $fsize = filesize($fullPath);
                $path_parts = pathinfo($fullPath);
                $ext = strtolower($path_parts["extension"]);
                switch ($ext) {
                    case "pdf":
                    header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\""); // use 'attachment' to force a download
                    header("Content-type: application/pdf"); // add here more headers for diff. extensions
                    break;
                    default;
                    header("Content-type: application/octet-stream");
                    header("Content-Disposition: filename=\"".$path_parts["basename"]."\"");
                }
                if($fsize) {//checking if file size exist
                  header("Content-length: $fsize");
                }
                readfile($fullPath);
                exit;
            }
        }
    ?>

这些函数在stacktrace.js中使用:

/**
 * Try XHR methods in order and store XHR factory.
 *
 * @return <Function> XHR function or equivalent
 */
var createXMLHTTPObject = function() {
    var xmlhttp, XMLHttpFactories = [
        function() {
            return new XMLHttpRequest();
        }, function() {
            return new ActiveXObject('Msxml2.XMLHTTP');
        }, function() {
            return new ActiveXObject('Msxml3.XMLHTTP');
        }, function() {
            return new ActiveXObject('Microsoft.XMLHTTP');
        }
    ];
    for (var i = 0; i < XMLHttpFactories.length; i++) {
        try {
            xmlhttp = XMLHttpFactories[i]();
            // Use memoization to cache the factory
            createXMLHTTPObject = XMLHttpFactories[i];
            return xmlhttp;
        } catch (e) {
        }
    }
}

/**
 * @return the text from a given URL
 */
function ajax(url) {
    var req = createXMLHTTPObject();
    if (req) {
        try {
            req.open('GET', url, false);
            req.send(null);
            return req.responseText;
        } catch (e) {
        }
    }
    return '';
}

这...似乎仅用于XHR,不是文件下载?我在这里看不到相关性。

我建议您使用mousedown事件,该事件在click事件之前被称为。这样,浏览器可以自然地处理click事件,从而避免了任何代码怪异:

(function ($) {


    // with this solution, the browser handles the download link naturally (tested in chrome and firefox)
    $(document).ready(function () {

        var url = '/private/downloads/myfile123.pdf';
        $("a#someID").on('mousedown', function () {
            $(this).attr("href", url);
        });

    });
})(jQuery);

来自Corbacho的出色解决方案,我刚刚适应摆脱var

function downloadURL(url) {
    if( $('#idown').length ){
        $('#idown').attr('src',url);
    }else{
        $('<iframe>', { id:'idown', src:url }).hide().appendTo('body');
    }
}

Firefox和Chrome经过测试:

var link = document.createElement('a');
link.download = 'fileName.ext'
link.href = 'http://down.serv/file.ext';

// Because firefox not executing the .click() well
// We need to create mouse event initialization.
var clickEvent = document.createEvent("MouseEvent");
clickEvent.initEvent("click", true, true);

link.dispatchEvent(clickEvent);

这实际上是firefox的“ chrome”方式解决方案(我尚未在其他浏览器上进行过测试,因此请对可编译性发表评论)

尝试下载文件时,可能会发生很多小事情。仅浏览器之间的不一致是一场噩梦。我最终使用了这个很棒的小图书馆。 https://github.com/rndme/download

关于它的好处是它的灵活性不仅适用于URL,还适用于您要下载的客户端数据。

  1. 文字字串
  2. 文字数据网址
  3. 文字斑点
  4. 文本数组
  5. html字符串
  6. HTML Blob
  7. Ajax回调
  8. 二进制文件

使用锚标记和PHP可以完成,请检查此答案

jQuery Ajax调用PDF文件下载

HTML
    <a href="www.example.com/download_file.php?file_source=example.pdf">Download pdf here</a>

PHP
<?php
$fullPath = $_GET['fileSource'];
if($fullPath) {
    $fsize = filesize($fullPath);
    $path_parts = pathinfo($fullPath);
    $ext = strtolower($path_parts["extension"]);
    switch ($ext) {
        case "pdf":
        header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\""); // use 'attachment' to force a download
        header("Content-type: application/pdf"); // add here more headers for diff. extensions
        break;
        default;
        header("Content-type: application/octet-stream");
        header("Content-Disposition: filename=\"".$path_parts["basename"]."\"");
    }
    if($fsize) {//checking if file size exist
      header("Content-length: $fsize");
    }
    readfile($fullPath);
    exit;
}
?>

我正在检查文件大小,因为如果您从CDN cloudfront加载pdf,您将不会得到迫使该文件以0kb下载的文件大小,为避免这种情况,我正在检查这种情况

 if($fsize) {//checking if file size exist
      header("Content-length: $fsize");
    }

我知道我参加晚会很晚,但是我想分享我的解决方案,它是上述Imagine Breaker解决方案的变体。我尝试使用他的解决方案,因为他的解决方案对我而言似乎最简单。但是就像其他人所说的那样,它不适用于某些浏览器,因此我通过使用jquery对它进行了一些改动。

希望这可以帮助某个人。

function download(url) {
  var link = document.createElement("a");
  $(link).click(function(e) {
    e.preventDefault();
    window.location.href = url;
  });
  $(link).click();
}

整个功能主体只是一种过于复杂的操作方式window.location.href = url。您创建的链接没有任何用处。

注意:并非所有浏览器都支持。

我一直在寻找一种使用jquery下载文件的方法,而不必从一开始就在href属性中设置文件url。

jQuery('<a/>', {
    id: 'downloadFile',
    href: 'http://cdn.sstatic.net/Sites/stackoverflow/img/apple-touch-icon@2.png',
    style: 'display:hidden;',
    download: ''
}).appendTo('body');

$("#downloadFile")[0].click();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

我在不使用JQuery 情况下使用@rakaloof的解决方案(因为在这里不需要它)。谢谢你的主意!这是基于vanillaJS表单的解决方案:

const uri = 'https://upload.wikimedia.org/wikipedia/commons/b/bb/Test_ogg_mp3_48kbps.wav';
let form = document.createElement("form");
form.setAttribute('action', uri);
document.body.appendChild(form);
form.submit();
document.body.removeChild(document.body.lastElementChild);
