How to make a Grails richui g:autocomplete field mandatory

Question

I can't see any way to make a richui autocomplete in grails mandatory. With a g:select I'd just use required="required" but this doesn't appear to work for g:autocompletes, any suggestions?

Currently my autocomplete looks like so...

<richui:autoComplete required="required" style="width:500px" name="autoLook[X].id" id="autoLook[X]." value="" action="${createLinkTo('dir': 'object/searchAJAX')}" forceSelection = "true" maxResultsDisplayed="20" minQueryLength ="3" onItemSelect="updateHiddenInput(id,X)" />

Is the only way of doing this going to be running a javascript check before submitting?

Answer 1

You can add required="required" when page is ready, like:

Add class required in the richui:autoComplete

<richui:autoComplete class="required" name="name[${idx}]" id="uniqueId[${idx}]" action="${createLinkTo('dir': 'oauthCallBack/test')}" onItemSelect="updateHiddenInput(id, this)"/>

and script

<script type="text/javascript">
    $(function () {
        $('.required').each(function (index) {
            jQuery(this).attr('required', 'required')
        });
    });
</script>
