JavaScript - Jquery - Count Checkboxes Same Value
Hey Guys,
I am stuck on something that is probably a straight forward issue. Just can't get my head around it. Basically I have a whole bunch of checkboxes and I want to count the number that have the same class (only when selected) Example: Code: <input type="checkbox" name="Paris" value="FR" /> <input type="checkbox" name="Marseille" value="FR" /> <input type="checkbox" name="Cardiff" value="UK" /> <input type="checkbox" name="London" value="UK" /> <input type="checkbox" name="ROME" value="IT" /> When user checks a checkbox, output the number of checked boxes that have the same value. My thoughts: Code: $("input[type="checkbox"]").click(function(event){
alert($('input[type="checkbox"]:checked').val($('input[type="checkbox"]:checked').val()).length);
});
Not sure what the correct logic should be. Anyone with any ideas? Similar TutorialsI am using the jQuery plugin - Nice Form. http://www.whitespace-creative.com/jquery/jNice/ When Nice Form is used it changes my checkboxes as seen below. So when you are using the browser you actually click the <div> and not the checkbox. Can anyone advise of a way for me to capture, in jQuery, when I am ticking the Email checkbox and when i'm ticking the SMS checkbox? PHP Code: <p> I would like to be contacted by <label style="padding-right: 10px;" for="comm_email">Email</label> <div class="NFCheck NFh" style="left: 431px; top: 490px;"></div> <input id="comm_email" class="NFhidden" type="checkbox" name="comm_email"/> <label style="padding-right: 10px;" for="comm_sms">SMS</label> <div class="NFCheck NFh" style="left: 534px; top: 490px;"></div> <input id="comm_sms" class="NFhidden" type="checkbox" name="comm_sms"/> </p> Thanks, Picco So, i have this code which retrieves php files for me using jquery and id love to get it working with Jquery history plugin. I tried modifying the code i got from the ajax demo to work for me, but i just couldnt do it as i do not know any javascript really.. ( actually what i tried was simply to change "#ajax-links a" to "#menu li a" and .html to .php ..but nothing.. :rolleyes: Id be very gratefull if someone would help me out with this one. All related code can be found bellow (the ones that should be needed anyways): This is the code that retrieves php files inside "#content" when item from "#menu li a" with the specified id is clicked Code: $(document).ready(function(){
//References
var change = $("#menu li a");
var loading = $("#loading");
var content = $("#content");
//Manage click events
change.click(function(){
//show the loading bar
showLoading();
//load selected section
if(this.id == "home")
{
change.load(this.className='current-page');
content.slideUp();
content.load("pages/index.php", hideLoading);
content.slideDown();
}
else if(this.id == "secondpage")
{
change.load(this.className='current-page');
content.slideUp();
content.load("pages/secondpage.php", hideLoading);
content.slideDown();
}
else
{
//hide loading bar if there is no selected section
hideLoading();
}
});
//show loading bar
function showLoading(){
loading
.css({visibility:"visible"})
.css({opacity:"1"})
.css({display:"block"})
;
}
//hide loading bar
function hideLoading(){
loading.fadeTo(1000, 0);
};
});
Heres the structure of the menu/content Code: <ul id="menu"> <li><a id="home" class="normal" href="#Home"></a></li> <li><a id="secondpage" class="normal" href="#Secondpage"></a></li> </ul> <div id="content"> <ul id="sec-menu"> <li><a id="link1" class="normal" href="#">Link1</a></li> <li><a id="link2" class="normal" href="#">Link2</a></li> </ul> </div> Heres the code that jquery history plugin uses in demo for ajax Code: jQuery(document).ready(function($) {
function load(num) {
$('#content').load(num +".html");
}
$.history.init(function(url) {
load(url == "" ? "1" : url);
});
$('#ajax-links a').live('click', function(e) {
var url = $(this).attr('href');
url = url.replace(/^.*#/, '');
$.history.load(url);
return false;
});
});

Thanks in advance! have a simple calculator i made with checkboxes and some Js. the problem is that it does not work in FF. any idea how this can work for IE Safari AND FF Code:
function getPrice(amount, boxName){
total = eval() ;
checked = document.getElementById(boxName).checked
if (checked){
total = parseFloat(form1.Total2.value) + parseFloat(amount);
}else{
total = parseFloat(form1.Total2.value) - parseFloat(amount);
}
total.toFixed(2);
form1.Total2.value = total
document.getElementById("total").innerHTML = "Total $"+total;
}
My form generates 1 to n records which contains check boxes. Based on some condition if I click a check box it has to check & disable some other check boxes automatically. I did it. But, at the same time if I un-check I have to un-check all the check boxes which were checked. Please let me know. Thanks a lot.
Good evening all, I have a bit of an issue with checkboxes - basically I need to allow only 1 selection and then have a comments box show when a checkbox is checked. I've gotten the comments box to show when the checkbox is checked but I can't seem to workout how to allow only one. I'd really like the user to be able to change their mind and make a different selection but only have 1 be selected at a time (sort of like radio buttons work). I know it would be much easier and probably better to use radio buttons but that isn't an option with this. (The actual HTML is produced using a style sheet in an application that I am interfacing with so all I can do is use the checkbox.) Here is the code I am using to show or hide the comments box. Code:
function HideComments()
{
var a1 = document.getElementById("crmForm_answer1").checked;
var a8 = document.getElementById("crmForm_answer8").checked;
var a2 = document.getElementById("crmForm_answer2").checked;
var a3 = document.getElementById("crmForm_answer3").checked;
var a4 = document.getElementById("crmForm_answer4").checked;
var a5 = document.getElementById("crmForm_answer5").checked;
var a6 = document.getElementById("crmForm_answer6").checked;
var a7 = document.getElementById("crmForm_answer7").checked;
var a9 = document.getElementById("crmForm_answer9").checked;
var a10 = document.getElementById("crmForm_answer10").checked;
if(a1==true)
{
document.getElementById("crmForm_answer1_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer1_value").parentNode.parentNode.style.display = 'none';
if(a8==true)
{
document.getElementById("crmForm_answer8_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer8_value").parentNode.parentNode.style.display = 'none';
if(a2==true)
{
document.getElementById("crmForm_answer2_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer2_value").parentNode.parentNode.style.display = 'none';
if(a3==true)
{
document.getElementById("crmForm_answer3_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer3_value").parentNode.parentNode.style.display = 'none';
if(a4==true)
{
document.getElementById("crmForm_answer4_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer4_value").parentNode.parentNode.style.display = 'none';
if(a5==true)
{
document.getElementById("crmForm_answer5_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer5_value").parentNode.parentNode.style.display = 'none';
if(a6==true)
{
document.getElementById("crmForm_answer6_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer6_value").parentNode.parentNode.style.display = 'none';
if(a7==true)
{
document.getElementById("crmForm_answer7_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer7_value").parentNode.parentNode.style.display = 'none';
if(a9==true)
{
document.getElementById("crmForm_answer9_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer9_value").parentNode.parentNode.style.display = 'none';
if(a10==true)
{
document.getElementById("crmForm_answer10_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer10_value").parentNode.parentNode.style.display = 'none';
}
Thanks in Advance Sam Hi all. I have the following problem that I require a pointer with. I have a php variable named "$seatid" This could contain 1 or many entries. I have a page full of checkboxes named A1-8, B1-8, C1-8 etc to P1-8 I want a way of greying out the checkboxes on the page that relate to the values that are contained in the php variable. So they cannot be clicked. It would also like to change the colour of the cell that the check box is contained in. It is important that the checkboxes or at least the table that contain the checkboxes remain, as it represents the layout of a theatre. Cheers for your help Hello. How can you modify this code so that if you click a checkbox that is ALREADY CHECKED, it will remain checked? By the way, I have searched the web on how to do this and the general consensus seems to be "use radio buttons instead", but I would not like to use radio buttons. I would like to use checkboxes, I think they look better for what I am trying to do. Thanks for any help Code: <input type="checkbox" id="ckbox1" onclick="if(this.checked){ document.myform.ckbox1.checked=true; document.myform.ckbox2.checked=false; document.myform.ckbox3.checked=false;}" checked="checked" />Best Match
<input type="checkbox" id="ckbox2" onclick="if(this.checked){ document.myform.ckbox1.checked=false; document.myform.ckbox2.checked=true; document.myform.ckbox3.checked=false;}" />All Words
<input type="checkbox" id="ckbox3" onclick="if(this.checked){ document.myform.ckbox1.checked=false; document.myform.ckbox2.checked=false; document.myform.ckbox3.checked=true;}" />Exact Phrase
I am trying to get a link that when clicked it will check all the checkboxes in my form. My problem is that my values are stored in an array: <INPUT TYPE=\"checkbox\" name=\"emailArray[]\" value=\"$email\"> print"<br><a href=\"#\" onClick=\"checkAll()\">check all</a><br>"; Here is my javascript function : function checkAll(){ alert('hi'); var df = document.selectEmailForm.elements; for (var i = 0; i < df.length; i++) { if (df[i].name == "emailArray[]" ) { document.selectEmailForm.emailArray[i].checked=true; } } } Any ideas? Any help is greatly appreciated. Thanks for your time! Hello, today 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: Code: <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: Code: <input type="checkbox" name="checkall" onchange="checkall('checked[]', this.checked)">
And here is the function: Code: 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. Help? This script works via "elem.checked" which is great for checkboxes (see http://javascript.internet.com/forms...heckboxes.html), but I need it to work with image buttons instead where there is no "checking" going on. Is this possible? I tried elem.onclick and elem.clicked but neither works. I don't know enough about onclick conditionals. Please help. Code: function UpdateCost() {
var sum = 0;
var gn, elem;
for (i=0; i<4; i++) {
gn = 'game'+i;
elem = document.getElementById(gn);
if (elem.checked == true) { sum += Number(elem.value); }
}
document.getElementById('totalcost').value = sum.toFixed(2);
}
tl;dr: Want to make the above work with <a onclick="UpdateCost()"><img></a>, not <input type="checkbox" onclick="UpdateCost()"> i'm using http://www.javascript-coder.com/html...lidation.phtml now I want to know how to validate a checkbox if i have <input type=checkbox id="c2" name=33>dd <input type=checkbox id="c2" name=33>ff.aa <input type=checkbox id="c2" name=33>ddd is it correct to have them all with the same id and how do I validate it using this validation routine? (or if this one doesn't work is there a specific validation functions -your can recommend that are easy to use for all different types of input) Hi, I have a few checkboxes in a form. Some of them work independently, but some make the others go on and off. Specifically the lower ones are controlling the upper ones. Can anyone explain why please? Code: <td> <input type="checkbox" name="weddingitem1" value="Toppers" id="Toppers"/><label for="Toppers" >Toppers<br /> <input type="checkbox" name="weddingitem2" value="Champers" id="Champers"/><label for="Champers" >Champers<br /> </td> irst post here, i'll try to be simple: I need to create a form where participants of a medical convention register to classes, each class lasts 3 hours, so a person who wants to attend to class starting at 10 am cannot register to 11 am, 12pm and 1pm classes, but he can register to 2pm and so on. There are 3 different classes per hour. i thought doing this using javascript, but i'm absolutely lost. Can you please give me a hint on how to do this? Thanks!! this is the part of the form that has the checkboxes. <form method="post" action="process.php"></form> <input type="checkbox" value="101" name="convention1"> 10 am: Cariovascular desease<br> <input type="checkbox" value="102" name="convention2"> 10 am: Changes on toracic surgeon<br> <input type="checkbox" value="103" name="convention3"> 10 am: New drugs on heart<br> <input type="checkbox" value="111" name="convention4"> 11 am: New drugs on heart (II)<br> <input type="checkbox" value="112" name="convention5"> 11 am: Dynamic process on blood pressure<br> <input type="checkbox" value="113" name="convention6"> 11 am: Aortic disease<br> <input type="checkbox" value="121" name="convention7"> 12 am: Pulmonar Pressure<br> <input type="checkbox" value="122" name="convention8"> 12 am: Open table<br> <input type="checkbox" value="131" name="convention9"> 1 pm: Neurological aspects on heart rate<br> <input type="checkbox" value="132" name="convention10"> 1 pm: Cardiovascular disease (II)<br> <input type="checkbox" value="133" name="convention11"> 1 pm: Mioresponse on heart failure<br> <input type="checkbox" value="141" name="convention12"> 2 pm<br> <input type="checkbox" value="142" name="convention13"> 2 pm<br> <input type="checkbox" value="143" name="convention14"> 2 pm<br> <input type="checkbox" value="151" name="convention15"> 3 pm<br> <input type="checkbox" value="152" name="convention16"> 3 pm<br> <input type="checkbox" value="153" name="convention17"> 3 pm<br> <input type="submit"></input> </form> Hello, I have a form generated by mySQL and PHP, and inside the form (named 'UpdateDB') each line has checkboxes, like so: Code: <input type="checkbox" name="checkbox[]" value="96" onclick="highlight(this,'check_96')"> The onclick is to highlight the row, that works fine. However, I wrote a javascript function that toggles the select all the checkboxes or none. This is done by an image: Code: <img src="img/select.png" align="top">
<a href="#" onClick="togBox('updateDB');"><img src="img/all.png" name="listToggle" align="top"></a>
Easy, right? So heres the Javascript function that the above image (the 'none' part) links to: Code: function togBox(form)
{ var myForm = document.forms[form];
document.listToggle.src=='http://gospeltruth.tv/admin/img/all.png' ? toggle = true : toggle = false;
(toggle) ? document.listToggle.src='img/none.png' : document.listToggle.src='img/all.png';
for( var i=0; i < myForm.length; i++ )
{
(toggle) ? myForm.elements[i].checked = 'checked' : myForm.elements[i].checked = '';
}
}
Its a brilliant function if I do say so myself, and this is what I dont get: two days ago, it was working fine, today, its not working at all. The image changes, but IE flags up the 'myForm.length' as an error. How was it working 2 days ago and not today, when I havent touched it? Can anybody advise why its not currently working? Thanks for your help, ~Chud37 Hi Guys, I'm currently working on a page working with separate categories and a whole lotta check boxes. My objective is to have one checkbox deselect the other checkboxes in its category without interfering with the rest. How would I go about doing this assuming the id tag is already in use and differs per tag? I was thinking about cycling through all checkbox tags and sorting them out via class but I'm looking for something possibly more efficient. |
