这是我尝试直接解决您的问题的尝试
基本上,您只需构建并执行AJAX调用堆栈,然后全部执行它们,然后在所有事件完成时调用提供的函数-提供的参数是所有提供的ajax请求的结果数组。
显然,这是早期代码-在灵活性方面,您可以对此进行详细说明。
<script type="text/javascript" src="http://jqueryjs.googlecode.com/files/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
var ParallelAjaxExecuter = function( onComplete )
{
this.requests = [];
this.results = [];
this.onComplete = onComplete;
}
ParallelAjaxExecuter.prototype.addRequest = function( method, url, data, format )
{
this.requests.push( {
"method" : method
, "url" : url
, "data" : data
, "format" : format
, "completed" : false
} )
}
ParallelAjaxExecuter.prototype.dispatchAll = function()
{
var self = this;
$.each( self.requests, function( i, request )
{
request.method( request.url, request.data, function( r )
{
return function( data )
{
console.log
r.completed = true;
self.results.push( data );
self.checkAndComplete();
}
}( request ) )
} )
}
ParallelAjaxExecuter.prototype.allRequestsCompleted = function()
{
var i = 0;
while ( request = this.requests[i++] )
{
if ( request.completed === false )
{
return false;
}
}
return true;
},
ParallelAjaxExecuter.prototype.checkAndComplete = function()
{
if ( this.allRequestsCompleted() )
{
this.onComplete( this.results );
}
}
var pe = new ParallelAjaxExecuter( function( results )
{
alert( eval( results.join( '+' ) ) );
} );
pe.addRequest( $.get, 'test.php', {n:1}, 'text' );
pe.addRequest( $.get, 'test.php', {n:2}, 'text' );
pe.addRequest( $.get, 'test.php', {n:3}, 'text' );
pe.addRequest( $.get, 'test.php', {n:4}, 'text' );
pe.dispatchAll();
</script>
这是test.php
<?php
echo pow( $_GET['n'], 2 );
?>
