Question

What I’m trying to do is the following in JS:

function getSuccessForTest(testName,version,fromRev,toRev,res) {        

        var params = {
            "methodToRun":"getSuccessForTest",
            "version":version,
            "startRev":fromRev,
            "endRev":toRev,
            "testName":testName     
        };          
        $.post("Stats.php", params,function(data){
            return parseInt(data.toString(),10);
        }, "json");         
    }   

    getSuccessForTest(data[i],version,fromRev,toRev,res);

What am I doing wrong ? whenever I make the call to getSuccessForTest, I get the POST result in Stats.php but the value isn’t returned to the calling function.

Thanks in advance !

That’s beacuse value is returned to the anonymous function (function(data){…). Use callbacks. Try this:

function getSuccessForTest(testName,version,fromRev,toRev,res, callback) {        

    var params = {
        "methodToRun":"getSuccessForTest",
        "version":version,
        "startRev":fromRev,
        "endRev":toRev,
        "testName":testName     
    };          
    $.post("Stats.php", params,function(data){
        callback(parseInt(data.toString(),10));
    }, "json");         
    }   

    getSuccessForTest(data[i],version,fromRev,toRev,res, function(res) {
        alert(res)
    } );
