I have made a forum thats look like this:
<form action="" method="post" id="contactform">
<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
$('select#species').change(function()
{
if ($(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 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?
Here is the HTML: [URL] I'm trying to uncheck the selected radio button, then set the value to 1 (Yes), basically overwriting theinitialvalue to 1. I've looked at prop(), val(), and attr(), and just don't know where to start. Should I select $('#set_q157 input') or$('#set_q157 input:radio'), or each individual radio?
Do I need to each them, and check if its checked, then change its value, or is there a way to select all three inputs as just one radial button? It would also need to work if the input has not yet been checked.
I have disabled a file input field which has a textbox above it. I am trying to make it so that when there is text in the textbox the file field is enabled and disabled when it is emtpy.

I want to test if a input field is empty or not, if it is I don't want to execute the rest of the script.

if ($('#phone').length) before
$('#search_customer').blur(function() to test the input field

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?

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.

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.

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.

My image upload form has a choice of either upload image by entering url or by browsing for a file, I'm trying to empty the file-input input if you focus on the url-input. I've tried bother these events on click/blur but neither seem to work like they would for a checkbox or text input. [code]...
View 7 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 currently developing an online work brief, where the user has to
enter details regarding the project into a form. I've come to a section
in the form where the user has the option of selecting between two
checkboxes and an input element. I have to ensure that at least one of
the checkboxes have been checked or that the input element is not
empty. I've come up with this function:
function validateMedia(){
var count = 0;
if(document.workBrief.mediaOnline.checked){
count++;
}
if(document.workBrief.mediaPrint.checked){
count++;
}
if(document.workBrief.mediaOther.value != ""){
count++;
}
if(count 0){
return true;
}else{
alert('Please choose at least one media option');
return false;
}}
I'm sure there is a more effiecient way of writing this.
I would like to check the value in an input box and if the value has changed, then perform the action. Being a newbie at Jquery, I am not sure about the syntax.
var timeout = undefined;
var str = ''; /* Get the initial value and if changed, do something */
$('#input_box').live('keyup', function() {
if(timeout != undefined) {
clearTimeout(timeout);
}
var timeout = setTimeout(function() {
timeout = undefined;
/* Do something */
$('#log').append('<div>Handler for input_box .keyup() called.</div>');
}, 1500);
});
The .find() method does not seem to match on input fields by using a class. The ti This problem seems to be only visible on input fields. The following is a demonstration of the issue:

This is probably going to show how new I am to jQueryI have a form with an input text field for entering a URL. The user will most likely paste a URL and I want to automatically verify it's status once the user leaves the field. Basically just make sure the page loads ok.I've found dozens of topics that are close to this, but my lack of jQuery skills is hindering me from adapting any of them properly.
View 3 Replies View RelatedI need to find a way of modifying this function so it only initiates a request if there is a period of say 2 seconds of inactivity. The user inputs some text, and if they stop typing for 2 seconds, it should then fire off the request. Can someone tell me how i can check for inactivity in the #inputString field? This must involve some kind of timer, but how should it be structured?the lookup function sends the current value of inputstring to another function which posts it to the server side file which then returns the results in a box.
