Code:

Rudimentary Empty Field Validator

Dec 1, 2005

<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..

Show Hidden Field That Is Not Empty After Page Reload

Dec 14, 2009

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'); ?>>

Setting An Empty Hidden Div As The Value Of A Form Field And Then Calling Inline Div Opener ?

Jul 23, 2010

I'm setting an empty hidden div as the value of a form field and then calling inline div opener using thickbox.js:

Code:
<a href="#" onclick="javascript:document.getElementById('previewdiv').innerHTML = document.forms['form1'].content.value;tb_show('Preview','#TB_inline?height=550&width=500&inlineId=previewdiv');"><span class="icon-32-preview" title="Preview"></span>Preview</a>
<div id="previewdiv" name="previewdiv" style="display:none;"></div>

The thickbox opens with the title "Preview", but is empty.I've alerted the div after setting it, and it does contain the formfield value.Why might this be happening? I've also tried setting the div like this (foo as dummy text - to no avail):

Code:
$('#previewdiv').html('foo');

Form Validation - Should Return Message Like "should Not Be Empty" When User Leaves Field Blank

Oct 8, 2010

I want to do a form validation and it should return a message like "should not be empty" when the user leaves the field blank..

I have html code like this

Now I want to know how can i display alert message to the user saying that the particular label name should not be empty..

For eg.. here I want to display alert as "Did you find this article useful? field should not be empty".... (Assuming this is mandatory)

I have so many fields like this in my form(checkbox, radio buttons, etc...) and i want to display alert with label name...

How can I do this using javascript.. (I know how to do validation in javascript popping up the alert(without label name), But I am not sure how to display alert with label name))))

IE ResponseText Is Empty

Feb 24, 2011

I'm trying, to fill a table with data I receive from a Servlet. In Chrome everything works fine. But when I try the app on IE the responseText is allways empty. The following is my JS code (using prototype):

function updateToDeleteTable(){
var url = 'getDefHidConFechaInsercionMayor?plantacion_id='+$('plantacion_id').
options[$('plantacion_id').selectedIndex].value +
"&fechaDesde="+$("dateSelect").options[$("dateSelect").selectedIndex].value;

[Code].....

I know the servlet returns a correct text, because when I enter the request uri in a new IE tab it returns the appropiate html code.

Allso when I check the variable response in the IE JS debugger the resaponse of the servlet is 200 (OK). I realy can't think of anything I'm doing wrong, exept, that maybe there is a size limit for the responseText.
