如何在jquery ajax成功回调函数中传递上下文

Question

var Box = function(){
    this.parm = {name:"rajakvk",year:2010};
    Box.prototype.jspCall = function() {
        $.ajax({
            type: "post",
            url: "some url",
            success: this.exeSuccess,
            error: this.exeError,
            complete: this.exeComplete
        });
    }
    this.exeSuccess = function(){
        alert(this.parm.name);
    }
}

I'm not getting Box object inside exeSuccess method. How to pass Box object inside exeSuccess method?

Use the context option , like this:

    $.ajax({
        context: this,
        type: "post",
        url: "some url",
        success: this.exeSuccess,
        error: this.exeError,
        complete: this.exeComplete
    });

The context option determines what context the callback is called with...so it determines what this refers to inside that function.
