Some javascript statements not working at all with IIS 7 and Windows 2008

I have the following code working fine with Win 2003 & IIS 6:

javascript:window.opener.document.formConfirmation.textBoxDateFrom.value = '01/01/2011';

However it does not work with Win 2008 with IIS 7!

I cannot change the code above since the logic is populated from a calendar DLL that I have no access to. I would like to know if it is a setting in IIS that restricts some of the Javascript on working. And if so, what can I do to make the code above work like before.

FYI, the following does NOT work in IIS 7:

document.Form1.txtAlias.value;

but this statement WORKS in IIS 7:

document.getElementById('txtAlias').value;

while BOTH work with IIS 6 !!! What is that about? Any help will help me regain some of my hours waste开发者_如何学JAVAd on this...

This is because you have hard code the control names, but this names are probably dynamic render by asp.net. I say probably because you can setup them to not dynamic change the name on render.

Change your control id with <%=Control.ClientID%> or use some other method to get the values of your controls.

For example.

document.getElementById('<%=txtAlias.ClientID%>').value

or

javascript:window.opener.document.<%=Form.ClientID%>.<%=textBoxDate.ClientID%>.value = '01/01/2011';

In this part of your code document.Form1.txtAlias.value;, probably the Form1 has change name and not the txtAlias.

• Other posible solution if you use asp.net version 4, is to use static id names on your controls.

• a tip, on your pages, on your web browser, make right click | view source code to see how your control renders (what id they get).
