    copied!<p>I'd like to use the jQuery.Form/Validate plugins to only allow my form to be submitted if any of inputs were actually changed.</p> <p>There is callback logic for this using <code>beforeSubmit:</code> : <a href="http://jquery.malsup.com/form/#options-object" rel="nofollow">http://jquery.malsup.com/form/#options-object</a>. However, I can't seem to make it work. </p> <p>Here's what I have so far: </p> <pre><code>$(document.body).on('click', 'input[type="submit"]', function(){ var $form =$('form'); $form.validate({ submitHandler: function($form) { $($form).ajaxSubmit({ beforeSubmit: function(arr, $form){ var value = '', storedValue=''; $($form+':input').each(function (index, el) { value=$(el).val(); storedValue=$(el).data("stored"); if(value!=storedValue){ console.log("Changed"); return true; } else { return false; console.log("NOT changed"); } }); ...success handling, etc.. beforeSubmit: function(arr, $form) { var value = '', storedValue=''; $($form+':input').each(function (index, this) { value=this.value; storedValue=$(this).data("stored"); if(value!=storedValue){ console.log("Changed");return true; } else { return false; console.log("NOT changed"); } }); } </code></pre> <p>Here's the HTML:</p> <pre><code>&lt;form id="myForm"&gt; &lt;input data-stored="my title" value="my title"/&gt; &lt;textarea data-stored="my description"&gt;my description&lt;/textarea&gt; &lt;input type="submit" value="submit/&gt; &lt;/form&gt; </code></pre> <p>Currently the console.log shows, <code>"Changed"</code> regardless of whether the <code>storedValue</code> is equal or not to the input.</p>
