Our catalog is based on the 'standard' store. Some research on the mail list only turns up variations on the solution of "tell the user to turn on javascript". This is an accessibility requirement so that is not really an option for us.</div><div><br></div><div>I think that the javascript code could probably be replaced using the 'mv_click' feature. However, in some cases javascript is used to change the form action and form profile when particular buttons are pressed. Although these changes could be made in the mv_click, the click is not processed until after the check_order is run for mv_form_profile.</div><div><br></div><div>So, for example, in the checkout process, we can have a mv_form_profile to validate the inputs on the shipping address. However, for the back key the mv_form_profile is turned off allowing </div><div>the user to hit back without having to get a valid shipping address entered.</div><div><pre id="line1"><span> <input type=hidden name=mv_form_profile value="Check_shipping"></span><span class="Apple-tab-span" style="white-space:pre"> </span><<span class="start-tag">input</span> <span class="attribute-name">type</span>=<a class="attribute-value">button</a> <span class="attribute-name">onClick</span>="</pre><pre id="line1"><a class="attribute-value"> this.form.mv_form_profile.value='';</a></pre><pre id="line1"><a class="attribute-value"> this.form.country_reset.value='1';</a></pre><pre id="line1"><span><a class="attribute-value"><span id="line819"></span> this.form.mv_action.value='back';
