jQuery validation on hidden form elements


I recently wrote a code where I will have a wizard like page with multiple tabs. Each tab is a Div element, on clicking on a tab, one div will be visible while hiding the other divs, an usual design.

I implemented an unobtrusive validation on the web page, and it all worked well.

 

After I upgraded my jquery.validation.js, my web page’s validation was not as expected. Then I compared the two versions of jquery.validation.js files (1.8.1 and 1.9).

In the comparison it was evident that by default the jquery validator ignores all the hidden elements in 1.9 version, whereas 1.8 does validate every control in the page, no matter they are visible or invisible.

 

Of course validating only the visible controls is an useful feature, but not in my case. So I had to override the default value.

I wrote the following code in the page to instruct the validator not to ignore the hidden controls.

<script type="text/javascript" language="javascript">
$.validator.setDefaults({ ignore: [] });
</script>

Setting the default has to happen right when we include the scripts on the page. This would not work if we do it after the page load in any control’s event handle.
