copied!<p>The following code does exactly what your code does:</p> <pre><code>var passedValidation = true; $('#fbsignup input').each(function(index) { if ($(this).val().trim() == '') { $('#fbsignup tr').filter('.' + $(this).attr('class').split(' ').slice(0, 1)).find('em').show(); passedValidation = false; } }); if (passedValidation) $('#fbcSignupModal').jqmHide(); return passedValidation; </code></pre> <p>... except for one caveat: it'll only work if the classes "firstName", "lastName", etc... are the FIRST class in the class attributes of your inputs. This limitation, and the convoluted line <code>$('#fbsignup tr').filter('.' + $(this).attr('class').split(' ').slice(0, 1)).find('em').show();</code>, only exists because I don't know the structure of your HTML. The selectors can be a lot cleaner (using <code>.sibling()</code>, <code>.children()</code>, <code>.parent()</code>, etc. if the HTML structure is known.</p> <p>Alternatively, include an array of all the classnames of your inputs:</p> <pre><code>var inputClasses = ['firstName', 'lastName', 'email', 'password', 'screenName']; </code></pre> <p>And iterate through these:</p> <pre><code>var passedValidation = true; $.each(inputClasses, function(index, className) { if ($('#fbsignup').find('input.' + className).val().trim() == '') { $('#fbsignup').find('tr.' + className + ' em').show(); passedValidation = false; } }); if (passedValidation) $('#fbcSignupModal').jqmHide(); return passedValidation; </code></pre> <p>The downside to this is that you'll have to manually update the array if you change/add inputs. Your best bet is probably to modify my first solution using the known structure of your HTML, or even convert classes to IDs.</p>
