Determine if page is valid in JavaScript - ASP.NET
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" onclick"ValidatePage();" /> <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>
You are checking for Page.IsValid
where you should be checking for Page_IsValid
(it's a variable exposed by the .NET validators) :)
The ASP.NET validation controls expose a client side API you can use with javascript: http://msdn.microsoft.com/en-us/library/aa479045.aspx
You should be able to check the Page_IsValid object to see if any of the validation controls are invalid.
