Question

I have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can’t seem to reference that text field through the javascript, since the form begins on the master page.

The following line will come up bogus:

document.form1.txtFindUser.value = blah.responseText;

This is because form1 is defined on the master page, while txtFindUser is on the current page.

How can these situations be handled?

Answer 1

How about that :

document.getElementById('txtFindUser').value = blah.responseText;

But if txtFindUser is your server control’s id, then you should use the code above like that :

document.getElementById('<%= txtFindUser.ClientID %>').value = blah.responseText;
