How Do I Check If At Least One Of Several Checkboxes Has Been Checked?
Jul 20, 2005
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.
I have a large form that I would like it to check if there are any check boxes that are checked, if there are then open the divs attached to them. I have this working off of an onclick event but it's not working on load. This link is very close but only works off of one checkbox. http://www.sitepoint.com/forums/php-...sh-756260.htmlHere is the code that I am currently using:
HTML Code: $('div[class^=opentoggle]').hide(); $('input[class^=toggle]').click(function() {
I don't understand why my code doesn't work?! I just want to check to see if a checkbox has been checked...
<script language="JAVASCRIPT" type="text/djs"> function checkCheckBoxes() { if (document.f1.Times[].checked == false { alert ('You didn't choose any of the checkboxes!'); return false;
Basically, I'm counting all the checked checkboxes and assign the count value to a hidden field in the form. <script language="JavaScript" type="text/javascript">
function KeepCount() { var count = 0 var max = document.getElementsByTagName('checkbox').length; FOR( var x=0; x<max; x++) {
i have a form when a user selects a name I then run some ajax code to fill in a td with checkboxes (with a choice of emails based on the name they selected)this all works but when I submit the form I can't get the values of the checkboxes that were checked.
I have a really weird problem. I update checkboxes (set them to true/false) through jQuery, and their "checked" attribute gets set (when I loop through it), but the checkbox state won't show in the browser. Has someone an idea what it could be?
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.
<script language="JavaScript"> function checkForNone() { checked=false; for (i=0,n=selectForm2.elements.length;i<n;i++) {
I'm having problems getting the values of selected checkboxes and outputting them to a textarea. This seems like quite a simple thing to do but its causing me a lot of bother! I am using a mixture of JavaScript and jQuery to find a solution to this.
<h2>Booking Form</h2> <form name="booking"> Please choose the days that would suit your visit: <br/> <input type="checkbox" name="days" value="Monday">Monday<br/> <input type="checkbox" name="days" value="Tuesday">Tuesday<br/> <input type="checkbox" name="days" value="Wednesday">Wednesday<br/>
Currently I optimize my website. I would like to use php, javascript or ajax to implement the asynchronous action:
I have an array of checkboxes: <input type="checkbox" name="checkboxArray[]" value="checkboxValue" />I would like to add functions that when the user check a checkbox, diplay the checkbox value below the web page right after the action, if the user continues to check another checkbox, show both value.
so that the submition is made by the onclick event, not a submit button. How can I make it?
I have a for and lets say 4 checkboxes. I want to get the values of the checkboxes that are checked & to get the values of the checkboxes that are not checked. So if someone check the A & C checkbox I will get that A&C has this value (because they are checked!) and B,&D has this value(because they are not checked). Example this is my table....
<script language="javascript"> function checkall(){ var chkd=document.getElementById('ckbox').value; num=form1.numberOfBlanks.length; var i=0; while(i<chkd.checked==true.length) { alert("hellow"); i++=; }} </script> This does not work.
I have two "series" of check boxes in a form. One named:
<input type="checbox" name="check_100[]" value="1" /> <input type="checbox" name="check_100[]" value="2" /> ...and so on
and one named
<input type="checbox" name="check_101[]" value="1" /> <input type="checbox" name="check_101[]" value="2" /> ...and so on.
I need to ensure that no more than 4 checkboxes from the first (100) series are checked simultaneously. I've managed to find some scripts that come close, but they all count all the checkboxes in the form instead of the specific ones that I'm interested in.
I am working on a form with a huge selection of checkboxes (certifications), arranged in a table (#certs). To make it easier for the user to check what certifications they have selected, I would like to add a list immediately following the #certs table that updates dynamically based on their selections.
I put a paragraph under the table with a span - ID certs_list. I was able to add to this with the following code, but if the checkbox is clicked multiple times, it keeps adding the same value over and over again. How can I simply add to the list (item 1, item 2, item 3) when a checkbox is checked and remove it if it is unchecked?
I'm trying to get this for about two days now but just can't figure it out. I would like some kind of function that let's me use a ID as selector, when a checkbox's is clicked (checked) in that div it counts that checked checkbox. When there are 4 checkboxes checked there must be a action (the other checkboxes get disabled). I just can't set it up. Maybe someone could help me out with a snippet?
Is there a way with JS that i can have some sort of label at the bottom of each column that will in real time display the number of boxes in that column that are checked? I am guessing it will be a function that is called within the OnClick method of the checkboxes.
