Question

This is annoying me.

I’m setting an array in beginning of the doc:

 var idPartner;

 var myar = new Array();
 myar[0] = "http://example.com/"+idPartner;

And I’m getting a number over the address, which is the id of partner. Great. But I’m trying to set it without success:

 $.address.change(function(event) {
   idPartner = 3;
   alert(idPartner);
 }

Ok. The alert is giving me the right number, but isn’t setting it.

What’s wrong?

Answer 1

Changing the value of the variable does not re-set the values within the array. That is just something javascript can’t do automatically. You would have to re-generate the array for it to have the new id. Could you add the id to the value where you use the array instead of pre-setting the values in the array containing the id?

Edit: For example, you would do:

var myArray = [];
var myId = 0;
myArray[0] = "http://foo.com/id/";

and when you need to use a value from the array, you would do this:

var theVal = myArray[0] + myId;
