Question

My question is:

Is it possible to do an Ajax request WITHIN a click function, with jQuery? (see example below), If so, what am I doing wrong? Because I’m not being able to do any request (I’m alerting the data through my success function and nothing is being retrieved).

Thank you very much in advance for any help! 🙂

 function tracker(){

    this.saveEntry = function(elementTracked, elementTrackedType){      
    var mode = "save";
    var dataPost = "mode="+mode+"&elementTracked="+elementTracked+"&elementTrackedType="+elementTrackedType;        
    $.ajax({
        type: "POST",
        url: 'myURL',
        data:dataPost,
        success:function(msg){
            alert(msg);             
        },
        beforeSend:function(msg){
            $("#trackingStatistics").html("Loading...");
        }
    });
    return;
},
    this.stopLinksSaveAndContinue = function(){
    var fileName;
    $("a[rel^='presentation']").click(function(e){      
        fileName = $(this).attr("rel").substring(13);   
        this.saveEntry(fileName,"Presentation");                                        
    })                  
}

}

If your anchor is linked with the href attribute, then this may be interrupting your AJAX request. A similar problem was recently discussed in the following Stack Overflow post:

• window.location change fails AJAX call

If you really want to stick to using AJAX for link tracking, you may want to do the following:

<a href="#" onclick="tracker('http://www.google.com/'); return false;">Link</a>

With the following JavaScript logic:

function tracker(url) {
    $.ajax({
        type: 'POST',
        url:  'tracker_service.php',
        data: 'some_argument=value',

        success: function(msg) {
            window.location = url;
        }
    });           
}
