Question:

Javascript - Update text box values

by | earlier

So, I have a text box and I have some javascript coding prompting for a value and then I want to put that value into the aforementioned text box.

My code is:

function prompter() {

X = prompt("Enter value","")

Update() }

function Update() {

document.form.txtbox.value = x }

The syntax is correct and have confirmed it by using more coding, but the text box does not update automatically after the script is run. Am I forgetting a step? So, if anyone has any ideas, they would be great. Thanks.

Two problems: non-matching case x variable X not same as x

Also if you are using name="txtbox" switch that to id="txtbox" and use

document.getElementById("txtbox")

so these are the correct ways (script goes in head):

<script type="text/javascript">



</script>

<body onload="prompter()">

<form id="myform" action="">

<p><textarea id="txtbox" rows="1" cols="20"> </textarea></p>

</form>

And, actually you could shorten the script up some unless you have other reasons I don't see to use two functions, you could just make it one like this:

<script type="text/javascript">



</script>
