JavaScript Visual Studio snippet for is object defined check.

February 10, 2014

Since I write a lot of JavaScript currently in Visual Studio these days, I lack one of the very common checks in JavaScript and that is testing if object exists.

I mean this check :

if (typeof (someObject) !==undefined) {
    someJSCodeHere();
}

If you want to use this code but not type it each time over and over again and speed your work up you probably thought a snippet that would save your keystrokes would come handy, but there is none in vanilla VS. So, you can use my snippet ,just import it to Visual Studio from Code Snippet Manager window (in VS 2013 – CTRL + K + B) and use it with typing def and then tab (or use CTRL + K + X and pick one).

Enjoy your speedup while working with JavaScript.

PS : do you know you can share snippets with your team mates?

PS2: If you want to edit snippets in you VS, this plugin might be a good idea : http://snippetdesigner.codeplex.com/

Hope this helps.
