How would you set the value in a form input field with javascript. I tried by my own but it is not working. can anyone correct it.

Incorrect Coding:

<script type="text/javascript">
var a = document.getElementById("name");
a.value = "some value";
</script>

<input type="text" id="name">

    Edit fiddle - JSFiddle

    Seem to work fine, you probably have some other issue in your code, unrelated to the one which you have posted. can you create a fiddle so we all be able to see?

        Yes, use jQuery ... it will make your live much easier. And btw, how do you debug your Javascript code? I use Firefox with FIREBUG, if you have issue in your code, then FIREBUG will help you to localize it.

    Your code looks alright, there must be other code that causing error. Post your URL so we can take a look.

    I believe your input is incomplete. It should be...

    <input type="text" id="name" value="some value">
