.NET Forum / ASP.NET / General / May 2008I can't find $get syntax information
Hi all, I was just looking at some example code in the VS2008 help for VB. In a JavaScript example I came across some syntax that I didn't recognize and could not find information about on the usual JS sites I use as resources. In a place where I expected to see "document.getElementById('elementId')", instead the Microsoft example use the syntax "$get('elementid')". So I tried it in some of my code and it seems to work fine. Can somebody explain this short-hand syntax to me or at least point to a resource where I can read about it? It sure beats the heck out of typing document.getElementById. I just want to make sure I won't run into any compatibility problems if I start using that syntax regularly. Thanks in advance... > Hi all, > I was just looking at some example code in the VS2008 help for VB.

Something in the JS files included by MS adds this function:- function $get(id) { return document.getElementById(id); } $get isn't defined by the script context.  SignatureAnthony Jones - MVP ASP/ASP.NET Thank you Anthony, That is VERY important to know. I did not knowingly include any Microsoft JS files in my code. When I look at the HTML source in the IE7 browser I can't find any function declaration for $get() or a reference to the .js file. But I have a bunch of 3rd party controls that that generate almost unreadable JavaScript, so maybe I missed it. I am now wondering if the IE browser simply interprets it correctly. Have a good day. >> Hi all, >> I was just looking at some example code in the VS2008 help for VB. In a [quoted text clipped - 19 lines] > > $get isn't defined by the script context. I bet you are referencing the external JavaScript file Just do not look for .js Look for script tag. You will find it in a form like this <script src="/WebResource.axd?....."> That is where $get is defined.

When I typed that same term into the searchbox on the page you provided, the 2nd article returned had exactly what I needed. Many thanks... >> Hi all, >> I was just looking at some example code in the VS2008 help for VB.
