What is the best way to determine if a form on an ASPX page is valid in JavaScript?
I am trying to check the validation of a user control that was opened using the JavaScript window.showModalDialog() and checking the 'Page.IsValid' property on the server side does not work. I am using ASP.NET validation controls for page validation.
If I have a page that is using a bunch of ASP.NET validation controls I will use code similar to the following to validate the page. Make the call on an input submit. Hopefully this code sample will get you started!
<input type=submit value=Submit onclickValidatePage(); />
<script type=text/javascript>
function ValidatePage() {
if (typeof (Page_ClientValidate) == 'function') {
Page_ClientValidate();
}
if (Page_IsValid) {
// do something
alert('Page is valid!');
}
else {
// do something else
alert('Page is not valid!');
}
}
</script>
