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 RepliesI am trying to check the user enter time with current system. If user enter the time less than the current system time then I want to display the alert box. But the code is not working. Here is the code
<html>
<head>
<title>test</title>
<script type="text/javascript">
var d = new Date();
var curr_hour = d.getHours();
var curr_min = d.getMinutes();

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 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 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 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))))

I am trying to allow a user to easily uncheck/check all checkboxes in a form by checking or unchecking a checkbox. The checkboxes would be in a form like so:
<form action="" method="post">
<input type="checkbox" name="checked[]" value="1">
<input type="checkbox" name="checked[]" value="2">
<input type="checkbox" name="checked[]" value="3">
<input type="checkbox" name="checked[]" value="4">
</form>
I use an event handler to call a function:
<input type="checkbox" name="checkall" onchange="checkall('checked[]', this.checked)">
And here is the function:
function checkall(box_name, current_state) {
all = document.getElementsByName(box_name);
action = (current_state == "checked") ? "false" : "true";
for (i = 0; i < all.length; i++) {
all[i].checked=action;
}}
The event handler should pass the name of the checkboxes and whether the "check all" checkbox is currently checked or not to the checkall() function. Nothing happens when I check/uncheck the "check all" function.
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 need to create a form that expands or collapses with more or less fields to fill in when the user selects or deselects a check box on it. This form also needs to be secure. What is the best way to accomplish this?

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.

View 2 Replies View Relatedser is able to create queries and issue them. The query is sent to the web-app by means of an ajax call. Then, the server computes the result set and a small subset (100) of tuples are sent back to the client for visualization.
These thing works with queries that are simple and do not require to the database long computations. As soon as I try a more complex query (computation requires ~ 7secs), the answer returned to the client is empty.
I suspect that this is a problem of timing out the connection, is that possible?

I have a form with several questions. Within each question there are several checkboxes. I need to ensure that the user checks at least one checkbox. They can check more but must check at least one.
How would I do this in Javascript?
I have a form with several types of checkboxes, and I'm trying to check all but one of them to determine if any of those have been checked. I do not want to check 'all', but I want to see if any of the 'check_' or 'check2_' checkboxes have been checked. There are a variable number of checkboxes, so this is just an example with two of each. Set 1 and Set 2 will always have the same number of checkboxes as each other, though.

For example i am choosing radio button name="2" - it show div id="ezhed" but when i press submit button name="preview" (the engine is phpBB) i am getting a preview but a page is refreshed and div id="nedel" (first) is shown. The question is - how can i make radio button name="2" selected even after pressing preview.
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?
