I have a form that is a regular form but in some cases it might be empty.
<form id="myform"></form>
or it might have some elements
<form id="myform"><input name="X" value="X" /><input name="Y" value="Y" /></form>
What is the proper way to count or check if the form has say inputs, select, textarea, etc..., or check if it's empty?
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?
View 6 Replies View RelatedI'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.

I'm wondering how to check if load() is empty because if it is, I do not want to show()
$("#orderList").load("OrderListHandler.ashx?action=" + action + "&oid=" + sid +, function()
{
// if nothing came back from the ajax request to .ashx, then I need to hide()
$("#noOrdersContainer").show();
});
I have
$('select#species').change(function()
{
if ($(this).val() == "")
{
[Code]....
I'm attempting to check if the #species combobox is empty, if its empty then alert empty.
That code seems like it should work, but it doesn't. How do I check if the selectbox value is ""?

I have a form with many fields... the fields are getting values from a
database.
I've tried onunload to just submit the form regardless of changes or
not but onunload and submit isn't working for me. Now I need some
type of event that will fire when a user tries to navigate from a page
to check to see if anything has changed and if so prompt them
(confirmation) to take action or not.
I know that the reset button only takes away anything that was added
to fields after the load so there must be some way to use the logic of
reset to simply check to see if fields have changed, right?
I have an array of list boxes. I need them to become disabled if the first one is checked (with an id of disabler_0), and I need them to be enabled if that box is unchecked. Right now it doesn't work.

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?
The problem is(as stated in the title) that i cannot remove some empty elements, which is the [code]...

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 == '')

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.

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.

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.
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.
I've been struggling trying to get a small order form to work the way I want it to. Here is a link to the live page: [URL] And here is the code in question:
[Code]...
I have two questions...
Question 1 How can I make this piece of script act a little smarter. Look at the order form, I'm catering for up to 4 people and providing lunch for them. If they select 3 people and the spaghetti bol for lunch, it's only adding $10 where it should be adding $30. Obviously this is simple multiplication but since the values in my form are prices it makes it a little tricky. I'm guessing an onselect on the first part of the form which changes the pricing of the other items would be the way to go, but how do I do this?
Question 2 The "Total Price" is placed before the <form> tag by the script. This is ok but it's not where I want it. How can I position this text elsewhere in the document?
I am running the scripts below which should return a string containing a URL.So far, it cannot find the form contents in Firefox, but displays the non-dynamic data such as ?Location=. It won't work at all in IE.
