How do I refer to a label in javascript?

[jacobryce]

I have a javascript function that is called when I click my server-side
submit button. I want to validate that one of my labels is not empty before
allowing a submit.
I cannot figure out how to access the value stored in myLabel.text.

For hidden form variables I use the following syntax in javascript:
myForm.myHidden.value

I tried a bunch of different things with no luck! Thanks in advance for any
help!

you would need to make the textbox an input with a runat=server tag.
then the javascript would be able to access the form value (regarding you've
named the form as well)

an ofcourse for .net to use the html input, you'de need that runat=server
tag as well as declaring the input in the code behind

I think serverside labels get rendered as <span> tags. View the source of
you page to check.

Then use

document.getElementByID

google it for more details

Hi jacobryce,

If the label is an <asp:label> control, then you can reference it in your
javascript code as:

<code>
<script language="javascript">
var labelText = '<% = Label1.ClientID %>';
alert(labelText);
</script>
</code>

HTH,

I couldn't get that to work, but I did get the following code to work:
var labelText = "<%= myLabel.Text %>";
alert(labelText);

Thank you.

Thanks, I had already tried that with no luck. But maybe my syntax was
incorrect.
alert(document.getElementById("myLabel").innerText ;
