How to pass context in jquery ajax success callback function

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.
