I am defining a javascript prototype with a function that has a jquery selector in it. An over simplified version of my code can be found below:

function MyObj(id1){
this.id1 = id1;
}
MyObj.prototype.MyFunc = function(id2){
$('#' + this.id1).val(id2)
}
var newObj = new MyObj("id1_val");

I cannot use this in MyFunc, because this is the context (as perseved by JQuery), Is there a way to access the value of id1? Is it even possible to have a prototype with a function that has jquery in it?

I do need to maintain access to the context, because the code is part of a form submission and I have $(this).submit();

EDIT: I have a function

bar(id2){
 var newObj = new MyObj("id1_val");
 Foo(id2, newObj.MyFunc)
}

bar is being called in fuction start() {bar}; window.onload = start;

`this` in your code refers to the context, not to `window`. – Teemu Mar 19 '15 at 17:37
You are right, I will update the question – Quantico Mar 19 '15 at 17:38

What do you mean ? if you `alert(this.id1)` you will get the value of `id1` – Royi Namir Mar 19 '15 at 17:40

Now, how are you calling `MyFunc`? If you're doing `newObj.MyFunc(...)` the code works as expected. – Teemu Mar 19 '15 at 17:40
@Teemu That's what i've written also – Royi Namir Mar 19 '15 at 17:41

@RoyiNamir Yep, jQuery doesn't have any affect to `this` value here. Ahaa, it appears that it's executed as a callback ... – Teemu Mar 19 '15 at 17:45
