javascript functions not working on asp.net page

[mcfly1204]

I have a page that contain input form, a contact us page. I also have a few javascript functions, one in particular sends the visitor back to the home page.

My javascript is not functioning properly, the user is supposed to be directed back to the home page, but instead the page simply seems to reload. I would assume that the form is trying to post back, however, I would like to avoid this if possible. In the past for other asp.net button, I could add:

if (!Page.IsPostBa ck)
{
code here...
}

Is there a similar work around for javascript functions?

I suppose there could be a different issue here. Has anyone at least heard of this type of thing happening previously. To simplify:

-1 .aspx page
-1 contact us form with submit button that initiates method of sending the user input as an email
-1 HTML input of type image that when click is supposed to initiate javascript funtion home(), but does not work properly and instead seems to reload the page.

Show your JavaScript code.

Show your JavaScript code.

Brace yourself,

function navURL(url) {
window.location .href = url;
}

OK, so how do you call this code?

<input type=image src="Images/QuikeyGreenLogo OnGREENfield.gi f" onClick="navURL ('http://www.physicaladv ertising.com'); return false;" />

Previously I did not have return false;. The function now operates properly.

On another note, on this same page, when the submit button is clicked, a c# method is called, I would like to call a different javascript function from that method if possible. Essentially the c# method sends the contents of the contact us page in an email, upon doing so I would like to call a javascript function that grays out the background and makes a div tag present. Can javascript be called from server side controls?

Yes, that should solve it and has.

Just output the JavaScript from the server-side code to be run when the page loads.
