I have an asp.net label on my webform. (The webform is based on a master
page.)

Using javascript how do I check the text value of the ASP.NET label? The
label is called lblCar.

Thanks!
 
This seems to work...

if
(document.getElementById("ctl00_ContentPlaceHolder1_lblUserRole").innerText
== "999")
 
Wow! Thanks!

Avoid hard-coding client-side element names, as they are not set in
stone...

Use this instead:
document.getElementById('<%=lblCar.ClientID%>').innerText
Click to expand...
 
In this case what is "ClientID" used for? Thanks...

question :) hehe

Right, it's the ID that is put in the generated HTML code.
