回调导致内存泄漏

Question

Model.GetData(function (args,jsonData) {
    RenderData(jsonData);
});

I am passing a callback to my model class,

var Model = (function () {
    function GetData(args,callback) {
       // do all math works. 

       var HTTPClient;

       HTTPClient.onload = function () {
           callback(this.responseText);
       };
    }

})();

Will my callback cause memory leak in my view page.

Answer 1

Yes. The onload global variable will store a reference to your function, which is in the same scope as your args and callback .
