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 made a forum thats look like this:

<div id="name-wrap">
<label for="name" class="req">Namn</label><span>Fyll i ditt för- och efternamn</span>

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 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'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?
I have a question about a selector of jQuery.
How can I select all empty elements?
I creating a form, i want submit if it is not empty, how can i do it?
View 1 Replies View RelatedI 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 (StreetNumber.value.length == 0) {
if (StreetName.value.length == 0) {
if (City.value.length == 0) {
alert("Please enter a street number, street name, or city.");

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 == '')
How do I check to see if HTML5 localstorage is empty?
I don't need to know what's inside just if there is anything inside.

This is returning empty all the time.

I'm doing a registration system and as you can see when i verify the fields, if it's empty it says that the FIELD_1 misses. And what i want is if the field is empty says that and then goes back, but i don't wanto the info already written disappears.I'm using ajax, i never worked with it, so i'm gonna ask you if i'm doing everything ok:registration form:

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.
View 4 Replies View RelatedCan I use JavaScript to have a select menu not display? Or a Div containing that select menu? I want the select menu not to display, if a certain data field is empty. I had tried a PHP code (hide region if), but that also deleted the functionality of the menu (onchange). I don't know how to put it in JavaScript, but what I want to say is "display div version, if version field is not empty".
View 3 Replies View Relatedi am trying to pass text from one select box to another select box. The logic is if 10 are added, no more passing must happen. Also if an item is already added, it mustn't be added again.I am using the for loop to check the existence of an item but it is not working: what am i doing wrong?
Code:
function PassSelectValues(){
//pass values from select boxes to select boxes
var counter;[code]....
why isn't counter incrementing at all? The alert message box does appear saying item exists but the item gets added anyway.
disable select until user puts mark in check box. Then enable select.I have two select box's on a page. The first asks what product, the second is based on the first and presents a list of pdf's according to which product the user selected. (yes, multi dimensional)What I have works fine, but now i need to make the user put a check mark in a check box before the First SELECT box becomes enabled/available.So basically, when they agree, they can get the download.Here are my select boxes.
HTML Code:
<form>
<select name="category" style="width:180px"></select>
<select name="site" style="width:180px" onchange="openLink(this.value)"></select>[code]....
(ignore the The 'open' button. It's there in case the default option is what the user wants, so they don't have reselect via the select box.)
1. How do I disable the select boxes by default on page load?
2. How do I detect that the user has put a tick in and the enable the disabled Select box?
<form name="form2" onSubmit="validateForm2()" action="" method="POST">

<tr>
<td> <select name="smonth"> <!--some options--> </select></td>
<td><input readonly="readonly" name="day" type="text" size="23"></td>

i have a group of check boxes, and i want to iterator over all the checked ones. i use the following code, but without luck.
$("input[type=checkbox][checked=true]").each(function()...);
[URL]
There are a couple of things I'm having issues with and was hoping someone could point me in the right direction:1) When you click the check boxes, the image area is selected in red. I'd like to make it so when you click on mild=yellow, moderate=orange, severe=red. But as the colour is specified in default_options. How do I specify the colour for each check box separately?2) I'd like to move the text and check boxes to the top left of the image (I can get the image to float right, but can't seem to move the text (as an asp:panel) to the top left. It is still at the bottom, even after playing with the height etc.
View 5 Replies View RelatedI tried using the following code to check if the user has selected a particular option in a single select drop down has been selected, then add a class to a div to display it but it's not working and I can't figure out why. I've tried a ton of other things to but this one seems to make the most sense.
if ($("#existing-subscriber option[value='Yes']").attr('select')) {
$(".information").toggleClass("show");
}
I just started using the grate validate plugin today and I can't really find an example of what I'm trying to customize...
Basically, I think it's confusing for a select element to change on focus instead of on change, meaning: the user forgets to select an option, the drop down is highlighted with some CSS, so use selects an option, but CSS error styling doesn't go away until the user clicks somewhere else on the page... A minor gripe, but I'm a big believer of the Steve Krug "don't make me think" school ;)
I'm still not quite clearly on how to implement own customizations of this plugin even after going through the docs...
I'm probably not writing this the proper way, but I have code that almost works.
$("#submit_button").click(function(){
$(".product").each(function(){
if ($(this).val() == '' ) {
$("#product_failed").css("display", "inline");
$("#myForm").submit(function(){
return false;
});//end submit false
}else{
$("#product_failed").css("display", "none");
$("#myForm").submit();
};//end if
});//end .product each function
});//end submit button click
The error message shows and hides properly based on whether the select menu value is "" or not, but if the value is not "" the form doesn't submit.

I'm new programmer in JavaScript. Can any one help in creating a
checkbox (by default selected) from JavaScript and creating Drop down
box (<select> ... </select>) from Javascript.
I found out how you can check if an array value exists but I can't seem to get it to work with the options array for some reason.
how I can find out if a certain select value exists?
