Check If The Form Is Empty

Apr 24, 2009

I need a simple script that will check onclick if the user has entered something into the input text form. If they haven't then just alert that you must enter something to search for a term. I had something like this before, but the problem I was having was that it was alerting but right after you click okay it would continue on to the next page... Which kinda make the whole alert thing pointless... Also, I'm about sick in tired of not knowing JavaScript, where is some great sites to get my learn on?

If A Check Box Is Or Not Empty - Allow User To Have One Box Checked At Any Time In A Form

Mar 31, 2009

I'm trying to figure out with Java Script how I would have Java Script check and see if a check box is or not empty. The goal is to only allow the user to have one box checked at any time in a form. That means, if they click on another one and there is already one checked, it would uncheck the one that was checked and make the one that the person checked on next checked.

Check If A Span Is Empty?

Feb 4, 2010

I need to check if a span is empty but every attempt at doing this has failed. This is in a for loop so it has to be able to change the span its checking.

var ids=new Array('PSN','XBL','xfire','steam','tweet','fbook');
for(i=0;i<=ids.length-1;i++)
{
if (document.getElementById(ids[i]).innerHTML == '')

[Code]....

Never runs... I have tried a few other things I've found on the internet but they don't see to work either.

I've debugged this and found out the code stops running on this line.

if (document.getElementById(ids[i]).innerHTML == '')

JQuery :: Empty Doesn't Check Values After Loading

May 7, 2009

I'm trying to select my textarea only if it is not empty. I have used :empty for this purpose. This works find when you load the page, however if you start typing in it still considers the value as it was when the page loads.

Example. If my textarea is empty when I load the page, it will consider it empty. If I starting typing in, and check if it is empty it still say it is empty.

The same vice versa. If my textarea has text when the page loads, then i clear that data, it still consider it filled not empty.

So how to make the check of :empty in real time?

Check Before Posting The Form (including A Botdetect Check)?

Jul 18, 2009

I have an .asp page for my customers which does just accepts e-mail information and passes this information to another .asp page. But before passing the info, a javascript checks whether the entered e-mail does match some certain rules. Rule1: If any input has been made at all, Rule2: If an "@" sign is there, if the"." is there and so on. upon pressing the submit button, the first rule works but the second rule does not. Could not figure it out why.

[Code]...

It is the function control() which validates the e-mail field. But it just validates whether the e-mail has been entered or not. The second check (with the @ sign) is not being made.

Test A Form Whether The Fields Are Empty Or Not?

Apr 5, 2009

I am trying to test a form whether the fields are empty or not. If so, displays warning, doesn't proceed. Here is my javascript , and the forms.

/* Validate Forms */
function validate(){
var notify = document.getElementById('notification1');
if ( null == document.getElementById('usrname').value ||

[Code]....

The problem is it works only for the passwd, but not for the usrname, meaning when the username is empty it shows the message as i wanted but right after showing the notification, it is going to the action page. Since it is returning false, it is not supposed to proceed. For passwd, it is fine, it shows the warning and stops without proceeding action.jsp.

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');

JQuery :: Hiding Subset Of Form Fields (with Empty Values) Using Focusout Handler?

I have a contact info form with about 16 fields. I need to hide a subset of fields for address when the end user either (1) tabs out of the subset group, (2) clicks anywhere outside the subset field group.

I do not want to hide the fields when the end-user is tabbing within the subset of address fields, yet the focusout handler is triggered when it shouldn't be.

Check A Form And Trigger A Hidden Form To Become Visible ?

Nov 18, 2011

I want to get the code ( I cant write it Im still a newbie ) to check a form user/pass and trigger another hidden form.

Heres what going on:

Have created a form, Form 1 Login: it has a username and pass fields. It shares the page with a Members Login form.

I want javascript to check the user/pass on Form 1 Login against a user/pass I assign. I assume I can assign one in the Javascript code.

The script does not send the form to the server, it just checks to see that the user/pass agrees with what Ive assigned.

The script, if the user/pass is the same as I assigned, triggers a Registration form to pop up that Ive hidden with CSS left:-999em.

Now the script has fulfilled its function, its done. But heres what continues and Adobe BC does this part.

User fills out the pop up Registration form with any user/pass, their valid email and name.

Clicks Submit and the form sends the New user a new personal pass and new username via email.

User adds New user/pass to Members form and is allowed into the site.

This is a round about way but, I can not use php or server side in this process, BC does not allow server side only client side. So Im doing a work around. I know someone could find the Javascript even in a js folder. Tight security is not an issue. I researched this for weeks and BC tells me it will work with their system...I just dont know how to write it.
