I want to ensure that when I check a certain box then another checkbox will be checked and unable to uncheck unless the master checkbox is deselected. When the ECOM checkbox is checked the 3d secure checkbox is automatically checked and cannot be unchecked until the Ecom box is deselected.
<%
If Request.QueryString("ECOM") = "ON" Then
Apply_ECOM_Check.Checked = True
End if
If Request.QueryString("MOTO") = "ON" Then
Apply_MOTO_Check.Checked = True
End if
If Request.QueryString("TERMINAL") = "ON" Then
Apply_TERMINAL_Check.Checked = True
End if
If Apply_ECOM_Check.Checked = False and Apply_MOTO_Check.Checked = False and Apply_TERMINAL_Check.Checked = False then
Apply_ECOM_Check.Checked = True
End if
%>
<script type="text/javascript">
function enableaddonservice() {
var ecom =document.getElementById("Apply_ECOM_Check").checked;
var moto =document.getElementById("Apply_MOTO_Check").checked;
var terminal =document.getElementById("Apply_TERMINAL_Check").checked;
if (ecom==true ) {
document.getElementById("addonservices").style.display = "block";
} else {
document.getElementById("addonservices").style.display = "none";
}
}
var chk1 = $('#Apply_ECOM_Check');
var chk2 = $('#Apply3DSecure');
//check the other box
chk1.on('click', function(){
if( chk1.is(':checked') ) {
chk2.attr('checked', true);
} else {
chk2.attr('checked', false);
}
});</script>
<input class="noborder" type="checkbox" ID="Apply_ECOM_Check" name="Apply_ECOM_Check" runat="server" style="width: 18px" value="ON" onClick="enableaddonservice();" /> ECOM
<input class="noborder" type="checkbox" ID="Apply_MOTO_Check" name="Apply_MOTO_Check" runat="server" style="width: 18px" value="ON" onClick="enableaddonservice();" /> MOTO
<input class="noborder" type="checkbox" ID="Apply_TERMINAL_Check" name="Apply_TERMINAL_Check" runat="server" style="width: 18px" value="ON" onClick="enableaddonservice()" /> TERMINAL
Once Ecom is selected above then the 3d secure below is automatically selected and can not be removed unless ecom is deselected
<table style="width: 100%">
<tr>
<td><input class="noborder" type="checkbox" ID="Apply3DSecure" name="Apply3DSecure" runat="server" style="width: 18px" /> 3D Secure </td>
<td> <input class="noborder" type="checkbox" ID="Apply_Mobilepaypage" name="Apply_Mobilepaypage" runat="server" style="width: 18px" /> Mobile PayPage </td>
<td> <input class="noborder" type="checkbox" ID="Apply_RepeatPayments" name="Apply_RepeatPayments" runat="server" style="width: 18px" /> Repeat Payments </td>
</tr>
The Java script works on it's own with the check boxes but because the 3d secure selection addon is only displayed when Ecom is selected. I think that interferes. I have tried many functions in these check boxes and it will not do anything.
The code you posted does not match the functionality that you ask for in your question so I am providing code for what you asked for when you say "When the ECOM checkbox is checked the 3d secure checkbox is automatically checked and cannot be unchecked until the Ecom box is deselected."
You will need two asp text boxes as follows:
<asp:CheckBox ID="Ecom" runat="server" AutoPostBack="true" />
<asp:CheckBox ID="threed" runat="server" AutoPostBack="true" Enabled="False" />
Now in the code behind you will need this code:
Private Sub Ecom_CheckedChanged(sender As Object, e As EventArgs) Handles Ecom.CheckedChanged
If Ecom.Checked = True Then
threed.Checked = True
ElseIf Ecom.Checked = False Then
threed.Enabled = True
End If
End Sub
I hope this helps.
If you're dynamically adding form fields to an existing form, what's the best way of adding validation?
Consider this fiddle: http://jsfiddle.net/yWGK4/
<form action="#" method="post">
<div id="parent">
<div class="child">
<input type="checkbox" name="box1[]" value="1" /> 1
<input type="checkbox" name="box1[]" value="2" /> 2
<input type="checkbox" name="box1[]" value="3" /> 3
</div>
</div>
</form>
<button id="addBoxes">Add Boxes</button>
<script>
$(function() {
var parentdiv = $('#parent');
var m = $('#parent div.child').size() + 1;
$('#addBoxes').on('click', function() {
$('<div class="child"><input type="checkbox" name="box'+m+'[]" value="1" /> 1 <input type="checkbox" name="box'+m+'[]" value="2" /> 2 <input type="checkbox" name="box'+m+'[]" value="3" /> 3 </div>').appendTo(parentdiv);
m++;
return false;
});
});
</script>
On that form I'm adding new checkbox groups, and want to make sure at least one box from each group is checked (not one box across all groups). Anyone got any clever methods? Everything I've looked at would get very complicated due to the dynamically added fields.
It doesn't matter if the checkboxes are dynamic when validating on submit etc. so something like this would check if at least one checkbox per .child is checked :
$('form').on('submit', function(e) {
e.preventDefault();
var valid = true;
$('.child').each(function() {
if ( ! $('[type="checkbox"]:checked', this).length ) // no box checked
valid = false;
});
if (valid) {
this.submit();
}else{
alert('error');
}
});
FIDDLE
If you want to check it using jQuery you can use `.each()
$(".child").each(function(){
var $this = $(this);
var checked = $this.find("input:checked");
if( checked.lenght == 0 ) {
alert("This group is not valid");
}
});
You can find more about this jQuery functions in this links:
each()
find()
here's what I came up with. Basically you loop over the .child groups and test if they have a checkbox in the checked state..
$('#checkBoxes').on('click', function(){
var uncheckedgroups = new Array();
$('.child').each(function(childindex, childelement){
var checkFound = 0;
$('.child').each(function(index, element){
if($(element).is(':checked')){
checkFound = 1;
}
});
if(checkFound == 0){
uncheckedgroups.push(childindex);
}
});
if(uncheckedgroups.length > 0){
alert("the following groups have no checked checkbox: " +
uncheckedgroups.join(','));
}
});
I have few checkboxes , out of which one is "Select All" and the others are some standalone's.
The requirement is that
Ifthe user click on "Select All" checkbox, then all other checkboxes will be checked.
If he unchecks the "Select All" checkbox , then everything will be unchecked.
And if any one of the individual checkbox is unchecked, then the "Select all" will be unchecked.
If all the four check boxes are checked, then the "Select All" will be checked.
I am using JQuery. I am able to achieve the first two but not the last two. My code is as under
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

CHeck Fiddle: http://jsfiddle.net/4vKwm/10/
maybe it gives some explanations
Ifthe user click on "Select All" checkbox, then all other checkboxes will be checked.
$("#chkSelectDeselectAll").click(function(){
if($("#chkSelectDeselectAll").is(':checked'))
{
("checkbox").each(function(){
$(this).attr('checked', 'checked');
});
}
});
If he unchecks the "Select All" checkbox , then everything will be unchecked.
$("#chkSelectDeselectAll").click(function(){
if(!$("#chkSelectDeselectAll").is(':checked'))
{
("checkbox").each(function(){
$(this).removeAttr('checked');
});
}
});
And if any one of the individual checkbox is unchecked, then the "Select all" will be unchecked.
$("checkbox").click(function(){
("checkbox").each(function(){
if($(this).is(':checked'))
{
$("#chkSelectDeselectAll").removeAttr('checked');
}
});
});
If all the four check boxes are checked, then the "Select All" will be checked.
$("checkbox").click(function(){
("checkbox").each(function(){
var yesno=true;
if(!$(this).is(':checked'))
{
yesno=false;
}
});
if( yesno)
{
$("#chkSelectDeselectAll").attr('checked', 'checked')
}
});
I would really recommend you to update your jQuery library and try to add a class to all the checkboxes you want to listen to, but:
var collection = $("input:checkbox:not(#chkSelectDeselectAll)").change(function() {
selectAll[0].checked = collection.filter(":not(:checked)").length === 0;
});
var selectAll = $("#chkSelectDeselectAll").change(function(){
collection.attr('checked', this.checked);
});
will work, I added the feature if you manually check all (or deselect one when you pushed select all) then it will toggle off the #chkSelectDeselectAll. A demo:
http://jsfiddle.net/voigtan/yTWKY/1/
Simply check the state of all checkboxes.
Working Demo: http://jsfiddle.net/XSdjQ/1/
Updated Demo: http://jsfiddle.net/XSdjQ/2/
Yet another Demo that works nicely with your markup: http://jsfiddle.net/XSdjQ/3/
You can try this code.
$(document).ready(function(){
$('#chkSelectDeselectAll').toggle(function(){
$('input[type=checkbox]').each(function(){
$(this).attr('checked',true);
});
},function(){
$('input[type=checkbox]').each(function(){
$(this).removeAttr('checked');
});
})
});
Thanks.

I have a checkbox Birthdate which shows the mm/dd only.And below it there is another checkbox called ShowYear which shows the year and this checkbox is only visible if the Bithdate checkbox is checked.
Now I want to uncheck the ShowYear checkbox automatically if the Birthdate checkbox is
unchecked through javascript.
<input id="cbxBirthDate" type="checkbox" onClick="javascript:uncheckShowYear(this);" />
<input id="cbxShowYear" type="checkbox" />
<script language="javascript" type="text/javascript">
function uncheckShowYear(obj)
{
if (obj.checked == false)
{
document.getElementById("cbxShowYear").checked = false;
}
}
</script>
First, give your check boxes ids eg:
<input type="checkbox" id="birth" />
<input type="checkbox" id="year" />
Javascript:
<script type="text/javascript">
window.onload = function(){
var birth = document.getElementById('birth');
var year = document.getElementById('year');
if (birth.checked == false)
{
year.checked = false;
}
}
</script>
If you are using jquery than
$(document).ready( function a()
{
if ( $('#birth').is(':checked'))
{
$('#year').attr('checked', false);
}
});
I have two radio buttons and want to post the value of the selected one.
How can I get the value with jQuery?
I can get all of them like this:
$("form :radio")
How do I know which one is selected?
To get the value of the selected radioName item of a form with id myForm:
$('input[name=radioName]:checked', '#myForm').val()
Here's an example:
$('#myForm input').on('change', function() {
alert($('input[name=radioName]:checked', '#myForm').val());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="myForm">
<fieldset>
<legend>Choose radioName</legend>
<label><input type="radio" name="radioName" value="1" /> 1</label> <br />
<label><input type="radio" name="radioName" value="2" /> 2</label> <br />
<label><input type="radio" name="radioName" value="3" /> 3</label> <br />
</fieldset>
</form>
Use this..
$("#myform input[type='radio']:checked").val();
If you already have a reference to a radio button group, for example:
var myRadio = $("input[name=myRadio]");
Use the filter() function, not find(). (find() is for locating child/descendant elements, whereas filter() searches top-level elements in your selection.)
var checkedValue = myRadio.filter(":checked").val();
Notes: This answer was originally correcting another answer that recommended using find(), which seems to have since been changed. find() could still be useful for the situation where you already had a reference to a container element, but not to the radio buttons, e.g.:
var form = $("#mainForm");
...
var checkedValue = form.find("input[name=myRadio]:checked").val();
This should work:
$("input[name='radioName']:checked").val()
Note the "" usaged around the input:checked and not '' like the Peter J's solution
You can use the :checked selector along with the radio selector.
$("form:radio:checked").val();
If you want just the boolean value, i.e. if it's checked or not try this:
$("#Myradio").is(":checked")
Get all radios:
var radios = jQuery("input[type='radio']");
Filter to get the one thats checked
radios.filter(":checked")
Another option is:
$('input[name=radioName]:checked').val()
$("input:radio:checked").val();
In my case I have two radio buttons in one form and I wanted to know the status of each button.
This below worked for me:
// get radio buttons value
console.log( "radio1: " + $('input[id=radio1]:checked', '#toggle-form').val() );
console.log( "radio2: " + $('input[id=radio2]:checked', '#toggle-form').val() );
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="toggle-form">
<div id="radio">
<input type="radio" id="radio1" name="radio" checked="checked" /><label for="radio1">Plot single</label>
<input type="radio" id="radio2" name="radio"/><label for="radio2">Plot all</label>
</div>
</form>
Here's how I would write the form and handle the getting of the checked radio.
Using a form called myForm:
<form id='myForm'>
<input type='radio' name='radio1' class='radio1' value='val1' />
<input type='radio' name='radio1' class='radio1' value='val2' />
...
</form>
Get the value from the form:
$('#myForm .radio1:checked').val();
If you're not posting the form, I would simplify it further by using:
<input type='radio' class='radio1' value='val1' />
<input type='radio' class='radio1' value='val2' />
Then getting the checked value becomes:
$('.radio1:checked').val();
Having a class name on the input allows me to easily style the inputs...
try this one.
it worked for me
$('input[type="radio"][name="name"]:checked').val();
In a JSF generated radio button (using <h:selectOneRadio> tag), you can do this:
radiobuttonvalue = jQuery("input[name='form_id\:radiobutton_id']:checked").val();
where selectOneRadio ID is radiobutton_id and form ID is form_id.
Be sure to use name instead id, as indicated, because jQuery uses this attribute (name is generated automatically by JSF resembling control ID).
Also, check if the user does not select anything.
var radioanswer = 'none';
if ($('input[name=myRadio]:checked').val() != null) {
radioanswer = $('input[name=myRadio]:checked').val();
}
If you have Multiple radio buttons in single form then
var myRadio1 = $('input[name=radioButtonName1]');
var value1 = myRadio1.filter(':checked').val();
var myRadio2 = $('input[name=radioButtonName2]');
var value2 = myRadio2.filter(':checked').val();
This is working for me.
I wrote a jQuery plugin for setting and getting radio-button values. It also respects the "change" event on them.
(function ($) {
function changeRadioButton(element, value) {
var name = $(element).attr("name");
$("[type=radio][name=" + name + "]:checked").removeAttr("checked");
$("[type=radio][name=" + name + "][value=" + value + "]").attr("checked", "checked");
$("[type=radio][name=" + name + "]:checked").change();
}
function getRadioButton(element) {
var name = $(element).attr("name");
return $("[type=radio][name=" + name + "]:checked").attr("value");
}
var originalVal = $.fn.val;
$.fn.val = function(value) {
//is it a radio button? treat it differently.
if($(this).is("[type=radio]")) {
if (typeof value != 'undefined') {
//setter
changeRadioButton(this, value);
return $(this);
} else {
//getter
return getRadioButton(this);
}
} else {
//it wasn't a radio button - let's call the default val function.
if (typeof value != 'undefined') {
return originalVal.call(this, value);
} else {
return originalVal.call(this);
}
}
};
})(jQuery);
Put the code anywhere to enable the addin. Then enjoy! It just overrides the default val function without breaking anything.
You can visit this jsFiddle to try it in action, and see how it works.
Fiddle
$(".Stat").click(function () {
var rdbVal1 = $("input[name$=S]:checked").val();
}
This works fine
$('input[type="radio"][class="className"]:checked').val()
Working Demo
The :checked selector works for checkboxes, radio buttons, and select elements. For select elements only, use the :selected selector.
API for :checked Selector
To get the value of the selected radio that uses a class:
$('.class:checked').val()
I use this simple script
$('input[name="myRadio"]').on('change', function() {
var radioValue = $('input[name="myRadio"]:checked').val();
alert(radioValue);
});
Use this:
value = $('input[name=button-name]:checked').val();

$("#submit").click(function(){
alert($('input:radio:checked').val());
});

If you only have 1 set of radio buttons on 1 form, the jQuery code is as simple as this:
$( "input:checked" ).val()
I've released a library to help with this. Pulls all possible input values, actually, but also includes which radio button was checked. You can check it out at https://github.com/mazondo/formalizedata
It'll give you a js object of the answers, so a form like:
<form>
<input type="radio" name"favorite-color" value="blue" checked> Blue
<input type="radio" name="favorite-color" value="red"> Red
</form>
will give you:
$("form").formalizeData()
{
"favorite-color" : "blue"
}
JQuery to get all the radio buttons in the form and the checked value.
$.each($("input[type='radio']").filter(":checked"), function () {
console.log("Name:" + this.name);
console.log("Value:" + $(this).val());
});
To retrieve all radio buttons values in JavaScript array use following jQuery code :
var values = jQuery('input:checkbox:checked.group1').map(function () {
return this.value;
}).get();
try it-
var radioVal = $("#myform").find("input[type='radio']:checked").val();
console.log(radioVal);
Another way to get it:
$("#myForm input[type=radio]").on("change",function(){
if(this.checked) {
alert(this.value);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="myForm">
<span><input type="radio" name="q12_3" value="1">1</span><br>
<span><input type="radio" name="q12_3" value="2">2</span>
</form>
From this question, I came up with an alternate way to access the currently selected input when you're within a click event for its respective label. The reason why is because the newly selected input isn't updated until after its label's click event.
TL;DR
$('label').click(function() {
var selected = $('#' + $(this).attr('for')).val();
...
});
$(function() {
// this outright does not work properly as explained above
$('#reported label').click(function() {
var query = $('input[name="filter"]:checked').val();
var time = (new Date()).toString();
$('.query[data-method="click event"]').html(query + ' at ' + time);
});
// this works, but fails to update when same label is clicked consecutively
$('#reported input[name="filter"]').on('change', function() {
var query = $('input[name="filter"]:checked').val();
var time = (new Date()).toString();
$('.query[data-method="change event"]').html(query + ' at ' + time);
});
// here is the solution I came up with
$('#reported label').click(function() {
var query = $('#' + $(this).attr('for')).val();
var time = (new Date()).toString();
$('.query[data-method="click event with this"]').html(query + ' at ' + time);
});
});
input[name="filter"] {
display: none;
}
