jQuery和Ajax池的问题？

在处理单个页面应用程序时，我目前正在为所有的调用构建一个JQuery，Ajax函数。对于一个典型的页面，我可能有3个Ajax调用。我的想法是，如果用户互联网出去，将这些Ajax调用保存在数组中，然后做一个计时器，继续检查用户是否有互联网。一旦他们有了互联网，就可以打电话了。因此，当用户离线时(除了对InternetOne的检查之外)，并且一旦他们回到在线时，他们会做他们想做的事情，就不会运行任何电话。

所以我有了这个代码：

beforeSend : function($xhr)
{
    self.ajaxPool.push($xhr);

    if(!self.validateConnection())
    {
        console.log(self.ajaxPool);
    }
}

所以我的问题是，当我得到连接、循环遍历我的数组到每个$xhr对象时，我可以调用它的函数来说，‘嘿，做你现在应该做的’？例如$xhr.complete()？ I'我在池上做了一个控制台日志，以便在连接关闭时查看对象，但是它其中的所有函数都不像是能做到这一点的样子。

I been using this Offline JS for my RIA applications. It's really reliable for your offline scenarios

• Monitors ajax requests looking for failure
• Confirms the connection status by requesting an image or fake resource
• Automatically grabs ajax requests made while the connection is down and remakes them after the connection is restored.

I would ditch the beforeSend entirely since you're using a pool anyways and do something like this...

//where you want to make your initial request somewhere in code
//do this INSTEAD of calling $.ajax(options)
ajaxPool.push(options);

//an interval to handle the queue
setInterval(function(){
    //nothing in the pool so do nothing
    if(ajaxPool.length < 1) return;
    //not online so don't try to send
    if(!validateConnection()) return;
    //hey we're online lets make the ajax request
    doAjax(ajaxPool.shift());
},200);

function doAjax(options){
    //add call backs since you seem to be using a single call back
    options.complete=function(data){ ... };

    //do call
    $.ajax(options);
}

You could make this more OOP and you could pause the interval when you know it's not being used, but I think this gets the basic concept across.
