    text
    copied!<p>I have a form which onsubmit() validates the form contents and hides the submit button and shows an image while its processing.</p> <pre><code>$(document).ready(function() { $('input[type="submit"]').click(function() { $(this).css('display', 'none'); $('&lt;img&gt;').attr('src', '../images/ajax-loader.gif').insertAfter($(this)); }); }); </code></pre> <p>JS:</p> <pre><code>function validateForm() { var x=document.forms["trial"]["username"].value; var splitted = x.match("^(.+)@abcd\.com$"); if (splitted != null) { return true; } return false; } </code></pre> <p>HTML:</p> <pre><code>echo "&lt;FORM name=\"trial\" action=\"index2.php\" method=\"POST\" onsubmit=\"return validateForm();\"&gt;"; echo "Access-Type: "; echo "&lt;select name=\"accesstype\" id=\"accesstype\"&gt;"; echo "&lt;option value=\"select\"&gt;-SELECT-&lt;/option&gt;"; echo "&lt;option value=\"adsl\"&gt;ADSL&lt;/option&gt;"; echo "&lt;option value=\"cable\"&gt;CABLE&lt;/option&gt;"; echo "&lt;/select&gt;&lt;br&gt;&lt;br&gt;"; echo "&lt;span id=\"username\" class=\"details\"&gt;Username (e.g john.smith@abcd.com) : &lt;input id=\"username\" type=\"text\" name=\"username\" maxlength=\"40\"&gt;&lt;/span&gt;&lt;br&gt;&lt;br&gt;"; echo "&lt;input type=\"submit\" name=\"submit\" value=\"submit\"&gt;"; echo "&lt;/FORM&gt;"; </code></pre> <p>It works fine so far if all the details provided by the user meet the requirements. However, if the form validation fails, I want the submit button to re-appear for the user to be able to make the necessary changes and resubmit the form.</p>
