After googling I thought I might of found a solution but it doesn't appear to be working :( Even if the input field is empty my script still executes.The solution I found How do I test whether an element exists?The only thing I really add was:
if ($('#phone').length) before
$('#search_customer').blur(function() to test the input field

I am having a form with two input fields. I want to enter some text in the first input field and then the second field should get the same text. Is there a simple way (maybe a plugin) to do this with jQuery? It would be perfect if I even could output all these input fields values as normal text in <p> or <li> tags.

Just a quick one here I want a regular expression that tests a string to find out if not empty. I am currently using /^[a-zA-Z0-9]+$/ which allows all alphanumeric characters, however unfortunately does not allow white space. As I am trying to use the RE for a form name input and I don't wish to separate first and last name, I want to allow users to enter their full name including spaces. Can anyone tell me an RE that allows all alphanumeric characters and white space in a string but does not allow an empty string

why datepicker is sending the current date when the input field is empty? this field is not required and can be left empty and is optional if a user wants to enter a date. i thought if the field was empty then no value should be sent.

<script type="text/javascript"><!--
function Validate_form(form) {
var fields = [];
this.add = function(element, err) {
if ( !('__validate' in form[element]) ) {
form[element].__validate = function() {
if (this.value=='') {
alert(err);
this.focus();
return false;
}
}
}
fields.push(form[element]);
}
this.check = function() {
var len = fields.length;
for (var i=0; i<len; i++)
if ( !fields[i].__validate() )
return false;
return true;
}
}
function form_onsubmit(form) {
var vform = new Validate_form(form);
vform.add('domain_name', 'The domain field is empty');
return(vform.check());
}
--></script>
<form name="signup" method="post" action="" onsubmit="return form_onsubmit();">
<input type="text" name="domain_name" />
<input type="submit" />
</form>
This is nothing special. just a basic empty field validator. it's probably not as efficient as it could be because it assigns the function to the various elements. It also only supports text fields. I was thinking of allowing a 3rd argument on Validate_form.add to accept something like Validate_form.stock.email/number/etc (functions). ah well..

I have a drop area that should be pulling a value from a hidden input field when activated.For some reason, the code can see the image and set the new values but trying to get the value of the input field always comes back undefined. It's the $newSKU2 value that isn't getting set.
var $newpic2 = $('#2').find('img').attr('src');
var $newtitle2 = $('#2').find('img').attr('title');
var $newtext2 = $('#2').parent().parent().find('font').text();

I have a form and in the form is a checkbox use as a switch to hide and unhide a two textbox. When the other textbox is hide, the other is unhide such as the code below. When the user click the submit button on the first time and there is an error, it reloads and the id="fieldset.-in_honor" hide because it is set to hide initially but not empty. My problem is, I want to show the fieldset whichever is not empty after submit button is click and there is an error so user will not enter any more information to the other field. Is that possible?
/*toggle switch*/
<p><input type="checkbox" name="in_honor" value="" id="checkmemoriam" onclick="showHide(this.name);" />Please check to make this donation in honor of someone special.</p>
/*hide textbox but unhide when the switch is on or the checbox is check*/
<fieldset id="fieldset-in_honor" class="fieldgroup" style="display:none">
<legend class="hide">In Honor Of</legend>
<p>To make this donation in honor of someone special, please complete the two fields below:</p>
<div class="formfield" <?php echo highlight('donate_honor_name'); ?>>
<label for="donate_honor_name">Name:</label>
<input id="donate_honor_name" name="donate_honor_name" class="text" type="text" value="<?php safeEcho($form['donate_honor_name'])?>" />
<?php helper_error('donate_honor_name'); ?>
</div>
<div class="formfield" <?php echo highlight('donate_honor_acknowledgement'); ?>>
<label for="donate_honor_acknowledgement">Acknowledgement should be sent to:</label>
<textarea id="donate_honor_acknowledgement" name="donate_honor_acknowledgement"><?php safeEcho($form['donate_honor_acknowledgement'])?>
