Answers:
Google编写了一些代码来帮助完成此任务。以下是一些示例:使用InfoBubble,样式标记和“ 信息窗口自定义”(使用OverlayView)的示例。
上面链接中的代码采用不同的途径来获得相似的结果。要点是直接设置InfoWindows的样式并不容易,使用附加的InfoBubble类而不是InfoWindow或覆盖GOverlay可能会更容易。另一种选择是使用javascript(或jQuery)来修改InfoWindow的元素,就像后来的ATOzTOA建议的那样。
这些示例中最简单的示例可能是使用InfoBubble而不是InfoWindow。通过导入此文件(您应该自己托管)可以使用InfoBubble:http://google-maps-utility-library-v3.googlecode.com/svn/trunk/infobubble/src/infobubble.js
与InfoWindow相比,InfoBubble具有非常好的风格:
 infoBubble = new InfoBubble({
      map: map,
      content: '<div class="mylabel">The label</div>',
      position: new google.maps.LatLng(-32.0, 149.0),
      shadowStyle: 1,
      padding: 0,
      backgroundColor: 'rgb(57,57,57)',
      borderRadius: 5,
      arrowSize: 10,
      borderWidth: 1,
      borderColor: '#2c2c2c',
      disableAutoPan: true,
      hideCloseButton: true,
      arrowPosition: 30,
      backgroundClassName: 'transparent',
      arrowStyle: 2
});
infoBubble.open();您还可以使用给定的地图和标记对其进行调用以在以下位置打开:
infoBubble.open(map, marker);作为另一个示例,“信息窗口自定义”示例从Google Maps API扩展了GOverlay类,并将其用作创建更灵活的信息窗口的基础。首先创建类:
/* An InfoBox is like an info window, but it displays
 * under the marker, opens quicker, and has flexible styling.
 * @param {GLatLng} latlng Point to place bar at
 * @param {Map} map The map on which to display this InfoBox.
 * @param {Object} opts Passes configuration options - content,
 *   offsetVertical, offsetHorizontal, className, height, width
 */
function InfoBox(opts) {
  google.maps.OverlayView.call(this);
  this.latlng_ = opts.latlng;
  this.map_ = opts.map;
  this.offsetVertical_ = -195;
  this.offsetHorizontal_ = 0;
  this.height_ = 165;
  this.width_ = 266;
  var me = this;
  this.boundsChangedListener_ =
    google.maps.event.addListener(this.map_, "bounds_changed", function() {
      return me.panMap.apply(me);
    });
  // Once the properties of this OverlayView are initialized, set its map so
  // that we can display it.  This will trigger calls to panes_changed and
  // draw.
  this.setMap(this.map_);
}之后,它将继续覆盖GOverlay:
InfoBox.prototype = new google.maps.OverlayView();然后,您应该重写你需要的方法:createElement,draw,remove和panMap。它相当复杂,但是从理论上讲,您现在只是自己在地图上绘制div,而不是使用普通的信息窗口。
您可以单独使用jquery修改整个InfoWindow ...
var popup = new google.maps.InfoWindow({
    content:'<p id="hook">Hello World!</p>'
});在这里,<p>元素将充当实际InfoWindow的钩子。一旦domready触发,该元素将变为可用并可以使用javascript / jquery进行访问,例如$('#hook').parent().parent().parent().parent()。
下面的代码只是在InfoWindow周围设置了2个像素的边框。
google.maps.event.addListener(popup, 'domready', function() {
    var l = $('#hook').parent().parent().parent().siblings();
    for (var i = 0; i < l.length; i++) {
        if($(l[i]).css('z-index') == 'auto') {
            $(l[i]).css('border-radius', '16px 16px 16px 16px');
            $(l[i]).css('border', '2px solid red');
        }
    }
});您可以执行任何操作,例如设置新的CSS类或添加新元素。
试玩元素以获得所需的东西...
google.maps.event.addListener(infowindow, 'domready', function() {
    // Reference to the DIV that wraps the bottom of infowindow
    var iwOuter = $('.gm-style-iw');
    /* Since this div is in a position prior to .gm-div style-iw.
     * We use jQuery and create a iwBackground variable,
     * and took advantage of the existing reference .gm-style-iw for the previous div with .prev().
    */
    var iwBackground = iwOuter.prev();
    // Removes background shadow DIV
    iwBackground.children(':nth-child(2)').css({'display' : 'none'});
    // Removes white background DIV
    iwBackground.children(':nth-child(4)').css({'display' : 'none'});
    // Moves the infowindow 115px to the right.
    iwOuter.parent().parent().css({left: '115px'});
    // Moves the shadow of the arrow 76px to the left margin.
    iwBackground.children(':nth-child(1)').attr('style', function(i,s){ return s + 'left: 76px !important;'});
    // Moves the arrow 76px to the left margin.
    iwBackground.children(':nth-child(3)').attr('style', function(i,s){ return s + 'left: 76px !important;'});
    // Changes the desired tail shadow color.
    iwBackground.children(':nth-child(3)').find('div').children().css({'box-shadow': 'rgba(72, 181, 233, 0.6) 0px 1px 6px', 'z-index' : '1'});
    // Reference to the div that groups the close button elements.
    var iwCloseBtn = iwOuter.next();
    // Apply the desired effect to the close button
    iwCloseBtn.css({opacity: '1', right: '38px', top: '3px', border: '7px solid #48b5e9', 'border-radius': '13px', 'box-shadow': '0 0 5px #3990B9'});
    // If the content of infowindow not exceed the set maximum height, then the gradient is removed.
    if($('.iw-content').height() < 140){
      $('.iw-bottom-gradient').css({display: 'none'});
    }
    // The API automatically applies 0.7 opacity to the button after the mouseout event. This function reverses this event to the desired value.
    iwCloseBtn.mouseout(function(){
      $(this).css({opacity: '1'});
    });
  });//将CSS放入样式表
.gm-style-iw {
  background-color: rgb(237, 28, 36);
    border: 1px solid rgba(72, 181, 233, 0.6);
    border-radius: 10px;
    box-shadow: 0 1px 6px rgba(178, 178, 178, 0.6);
    color: rgb(255, 255, 255) !important;
    font-family: gothambook;
    text-align: center;
    top: 15px !important;
    width: 150px !important;
}我使用以下代码来应用一些外部CSS:
boxText = document.createElement("html");
boxText.innerHTML = "<head><link rel='stylesheet' href='style.css'/></head><body>[some html]<body>";
infowindow.setContent(boxText);
infowindow.open(map, marker);我设计了谷歌地图信息窗口,其中包含图片和一些内容,如下所示。
map_script(仅供参考infohtml HTML)
for (i = 0; i < locations.length; i++) { 
    var latlng = new google.maps.LatLng(locations[i][1], locations[i][2]);
    marker = new google.maps.Marker({
        position: latlng,
        map: map,
        icon: "<?php echo plugins_url( 'assets/img/map-pin.png', ELEMENTOR_ES__FILE__ ); ?>"
    });
    var property_img = locations[i][6],
    title = locations[i][0],
    price = locations[i][3],
    bedrooms = locations[i][4],
    type = locations[i][5],
    listed_on = locations[i][7],
    prop_url = locations[i][8];
    content = "<div class='map_info_wrapper'><a href="+prop_url+"><div class='img_wrapper'><img src="+property_img+"></div>"+
    "<div class='property_content_wrap'>"+
    "<div class='property_title'>"+
    "<span>"+title+"</span>"+
    "</div>"+
    "<div class='property_price'>"+
    "<span>"+price+"</span>"+
    "</div>"+
    "<div class='property_bed_type'>"+
    "<span>"+bedrooms+"</span>"+
    "<ul><li>"+type+"</li></ul>"+
    "</div>"+
    "<div class='property_listed_date'>"+
    "<span>Listed on "+listed_on+"</span>"+
    "</div>"+
    "</div></a></div>";
    google.maps.event.addListener(marker, 'click', (function(marker, content, i) {
        return function() {
            infowindow.setContent(content);
            infowindow.open(map, marker);
        }
    })(marker, content, i));
}最重要的是CSS
 #propertymap .gm-style-iw{
    box-shadow:none;
    color:#515151;
    font-family: "Georgia", "Open Sans", Sans-serif;
    text-align: center;
    width: 100% !important;
    border-radius: 0;
    left: 0 !important;
    top: 20px !important;
}
 #propertymap .gm-style > div > div > div > div > div > div > div {
    background: none!important;
}
.gm-style > div > div > div > div > div > div > div:nth-child(2) {
     box-shadow: none!important;
}
 #propertymap .gm-style-iw > div > div{
    background: #FFF!important;
}
 #propertymap .gm-style-iw a{
    text-decoration: none;
}
 #propertymap .gm-style-iw > div{
    width: 245px !important
}
 #propertymap .gm-style-iw .img_wrapper {
    height: 150px;  
    overflow: hidden;
    width: 100%;
    text-align: center;
    margin: 0px auto;
}
 #propertymap .gm-style-iw .img_wrapper > img {
    width: 100%;
    height:auto;
}
 #propertymap .gm-style-iw .property_content_wrap {
    padding: 0px 20px;
}
 #propertymap .gm-style-iw .property_title{
    min-height: auto;
}您也可以使用CSS类。
$('#hook').parent().parent().parent().siblings().addClass("class_name");美好的一天!
