I have a little problem accessing a js variable, declared in the markup of an ascx control.
The variable is declared like this:

```
var testValue = $('<%=leftProdTabPanel_LinkDiv_Values.ClientID %>');

```

Now I need to access this variable from another .js file which is loaded in the markup. I tried it using this way:

```
eval('testValue')

```

And this way:

```
window["testValue"]

```

But unfortunately it doesnt work. Is this even possible? If yes, do you have any hints for me?

Thank you very much!
