So first off I did search and I found this Enable/Disable a dropdownbox in jquery which got me on the right track. I'm new to jquery so when seeing other code I can adapt it to fit and work for me.
So what i'm asking is how do you make it check to see if two check boxes condition are true?
<script>
$(document).ready(function() {
$("#box1").click(function() {
if ($(this).is(":checked")) {
$("#tech1").prop("disabled", false);
} else {
$("#tech1").prop("disabled", true);
}
});
});
</script>
I want it to be if box1 and box2 are checked enable this box? I understand you can do it with an if statement, but I'm not sure where exactly it goes. Thanks in advance.
Would this work:
$("#box1").click(function() {
if ($(this).is(":checked")) &&
$("#box2").click(function() {
if ($(this).is(":checked"))
I doesn't work and I assume thats because that above creates two functions and not the if statement that I need.
Include both in the event handler, and check if both are checked
$(document).ready(function() {
var boxes = $("#box1, #box2");
boxes.on('change', function() {
var disabled = boxes.filter(':checked').length === boxes.length;
$("#tech1").prop("disabled", disabled);
});
});
FIDDLE
Consider box1 & box2 checkboxes defined with a css class boxes as below:
<input type="checkbox" id="box1" class="boxes" />
<input type="checkbox" id="box2" class="boxes" />
Now you can use box class as jquery selector to do your task
<script>
$(document).ready(function() {
$(".boxes").click(function(){
if($(".boxes:checked").size() == $(".boxes").size()){
$("#tech1").prop("disabled", false);
}else{
$("#tech1").prop("disabled", true);
}
);
});

I call a function in jquery for a checkbox toggle change. It works as expected.
Now I want to change this when the box is checked show some tables else hide.
But I don't know how to modify my function.. [1]
How can I modify this ?
[1]
HTML
<label class="checkbox"> <input type="checkbox" id="toggleSequence" name="sequence_check" id="sequence_check">
Jquery
$("#toggleSequence").change(function(e){
if($(this).is(":checked")){
$(this).parent().next().show();
}else{
$(this).parent().next().hide();
}
});
JS Fiddle
$('#toggleSequence').parents('table').next().hide(); // first you need to hide it use can also use css for this
$("#toggleSequence").change(function (e) {
if ($(this).is(":checked")) {
alert();
$(this).parents('table').next().show();
} else {
$(this).parents('table').next().hide();
}
});
I have this jQuery code:
$(document).ready(function(){
$('.checkdisplay').change(function(){
if(this.checked)
$('.todisplay').fadeIn('slow');
else
$('.todisplay').fadeOut('slow');
});
});
This works great only if I check the .checkdisplay radio button: the div appears, but after, if i uncheck .checkdisplay radio button, the div .todisplay doesn't disappear.
Where i'm wrong? :(
EDIT:

You need to test all the radios and only show on the one with the correct class
You could have used ID too
Notice I use .on("click" since change needs a blur in some browsers
Live Demo
$(function(){
$("input[name='roomdoor']").on("click",function(){
if ($(this).hasClass("checkdisplay") && this.checked)
$('.todisplay').fadeIn('slow');
else
$('.todisplay').fadeOut('slow');
});
});
$(document).ready(function () {
$('.radio').change(function () {
if ($(this).hasClass('checkdisplay') && this.checked) $('.todisplay').fadeIn('slow');
else $('.todisplay').fadeOut('slow');
});
});
Demo
The problem is, you can't uncheck a radiobutton.
Problem is your radio button, you should use checkbox like,
Once a radio button having class checkdisplay is checked then it will be checked, how it can be unchecked
<input type='checkbox' class='checkdisplay' />
<div class='todisplay'>test</div>
Demo
Updated, try this like,
$(document).ready(function(){
$('.radio').change(function(){// add onchange on radio class
// check the radio has checkdisplay class or not
if($(this).hasClass('checkdisplay') && this.checked)
$('.todisplay').fadeIn('slow');
else
$('.todisplay').fadeOut('slow');
});
});
Working demo
$('.checkdisplay').click(function() {
if( $(this).is(':checked')) {
$(".todisplay").fadeIn('slow');
} else {
$(".todisplay").fadeOut('slow');
}
});
I have group of checkboxes and that are compulsory to be applied but the situation is user can be able to check only one check box at a time. So, for this I have implemented something like this with the help of internet. No doubt it works fine when there are no checkbox checked by default. But suppose, one of the checkbox is checked true when page loads, then this does not works unitl I click on checkbox twice.
Here is what I am using::
So , Assuming I have set of 5 checkboxes, I set same class name for all the checkboxes and then
<input type="checkbox" class="myclass" onclick="Checkme(this.className);"/>
<input type="checkbox" class="myclass" onclick="Checkme(this.className);"/>
<input type="checkbox" class="myclass" onclick="Checkme(this.className);"/>
<input type="checkbox" class="myclass" onclick="Checkme(this.className);"/>
<input type="checkbox" class="myclass" onclick="Checkme(this.className);"/>
In View page I have declared::
function Checkme(class_Name) {
Check_OR_Uncheck(class_Name);
}
In Common js::
function Check_OR_Uncheck(class_Name) {
$("." + class_Name).click(function () {
if ($(this)[0].checked) {
$("." + class_Name).each(function () {
$(this)[0].checked = false;
});
$(this)[0].checked = true;
}
else {
$(this)[0].checked = false;
}
});
}
Please Help me to achieve this..
Keep your code in the document ready event. This will register the click event for "myclass".
$(".myclass").click(function () {
if ($(this)[0].checked) {
$(".myclass").each(function () {
$(this)[0].checked = false;
});
$(this)[0].checked = true;
} else {
$(this)[0].checked = false;
}
});
jsfiddle
You could use document ready handler and call method:
jsFiddle
$(function(){
$(':checkbox:checked').each(function(){
Checkme(this.className);
});
});
Try this
$(function(){
$('.myclass').click(function(){
var s=$(this).prop('checked');
if(s==true)
{
$('.myclass').prop('checked',false)
$(this).prop('checked',true)
}
});
});
Or
You simply can use
if(s==true)
{
$(this).siblings().prop('checked',false);
}
FIDDLE
Try this
$(function(){
$('input:checkbox').prop('checked', false)
$('input:checkbox').click(function(){
if($(this).is(':checked')){
$('input:checkbox').not(this).prop('checked', false);
}
});
})
Instead of implementing a group of check boxes that behave like a group of radio buttons, I suggest implementing a group of radio buttons that look like a group of check boxes:
input[type=radio] {content:url(mycheckbox.png)}
input[type=radio]:checked {content:url(mycheckbox-checked.png)}
This approach simplifies your implementation; you have two one-line CSS rules instead of a JS event handler function, event binding (on both document ready and the HTML element itself), not to mention a possible dependency on jQuery (if you choose to use it).
The catch to this approach is that it requires CSS3 support. For more info, check out this SO answer: https://stackoverflow.com/a/279510/2503516
I am trying to check if a radio box is checked using JavaScript, but I can't seem to figure it out properly.
This is the HTML code:
<input type="radio" name="status" id="employed_yes" value="yes">
<input type="radio" name="status" id="employed_no" value="no">
I have tried using jQuery as follows:
$(document).ready(function() {
if($('#employed_yes').is(':checked')) {
// do something
}
});
Also, I tried using pure Javascript by getting the element and check its 'checked' attribute, but it didn't work.
I look forward to your insight!
Thank you!
Use onchange
$('input[type="radio"]').on('change',function(){
if($('#employed_yes').is(':checked')) {
alert("yes");
}
});
DEMO
Try to check using name of the radio buttons like
if($('input[name="status"]').val() != "") {
// do something
} else {
alert("Select an Status");
}
Your solution doesn't work because when the page loads the checkbox's default state is unchecked, which is when the jQuery code runs.
You need to listen for the change event on the checkbox like so:
$(document).ready(function() {
$("#employed_yes").change(function() {
if(this.checked) {
document.write("checked");
}
});
});
Demo: http://jsfiddle.net/7CduY/
Try this. This will alert Hi on document ready if the any radio button is checked. If you want to check on specific event then you can bind on any event to check same.
$(document).ready(function() {
if($('input[type=radio]').is(':checked')) {
alert("Hi");
}
});
if($('input:radio:checked').text("yes") {
// do something
}
Got the idea from the jQuery forum. http://forum.jquery.com/topic/how-to-check-whether-all-radio-buttons-have-been-been-selected
Dude, I think you Wanted, whether radio button is checked or not, this what i understand from your question
If so here it is
$(document).ready(function() {
$('input[type="radio"]').on('change',function(){
if($('[name=status]:checked').length) {
alert("checked");
}
});
});
FIDDLE DEMO
Pure JS:
<input type = "button" value = "What?" name = "wic" onclick = "whatischecked(this.name);" />
Event onClick:
function whatischecked(name) {
var
emp = document.getElementById("employed_yes").checked
nonemp = document.getElementById("employed_no").checked
if (emp) {
alert("Employed");
};
if (nonemp) {
alert("Non-Employed");
};
if ((emp == false) & (nonemp == false))
{
alert("nothing checked")
};
}
I am trying to disable a order button when the page loads and enable it when one checks the Terms and condition checkbox.

if(j$('input[name="checkbox1"]').not(":checked"))
{
j$('input[name="Order"]').attr('disabled', 'disabled');
}
else
{
j$('input[name="Order"]').removeAttr('disabled');
}
j$('#checkbox1').change(function(){
if(j$('input[name="checkbox1"]').is(":checked")
{
j$('input[name="Order"]').attr('disabled', 'disabled');
}
else
{
j$('input[name="Order"]').removeAttr('disabled');
}
}
});
Thanks

The code you provided had some missing ( and {, here is an updated version with some changes to handle the checkbox state properly:
var j$ = jQuery.noConflict();
j$(document).ready(function() {
var checkbox1 = j$('#checkbox1');
var order = j$('input[name="Order"]');
var verifyChecked = function() {
if (checkbox1.is(":checked") === false) {
order.attr('disabled', 'disabled');
} else {
order.removeAttr('disabled');
}
};
verifyChecked();
checkbox1.change(verifyChecked);
});
Here is a jsfiddle with it working:
http://jsfiddle.net/7uRf6/4/
You have missed a closing parenthesis
if(j$('input[name="checkbox1"]').is(":checked")
should be
if(j$('input[name="checkbox1"]').is(":checked"))
Also you can use an id selector instead of this attribue selector.
And if you want to enable the button when the checkbox is checked you have to
if(!j$('input[name="checkbox1"]').is(":checked"))
in your change event,
if(j$('input[name="checkbox1"]').is(":checked")
it should be
if(j$('input[name="checkbox1"]').not(":checked")
I suggest you to create a function to check it.
var j$ = jQuery.noConflict();
j$(document).ready(function(){
ToggleButton();
j$('#checkbox1').change(ToggleButton);
});
function ToggleButton()
{
if(j$('input[name="checkbox1"]').not(":checked"))
{
j$('input[name="Order"]').attr('disabled', 'disabled');
}
else
{
j$('input[name="Order"]').removeAttr('disabled');
}
}
<script src="jquery.js"></script>
<script>
$(document).ready(function (){
$('#ch').click(
function (){
if($(this).is(':checked')){
$('#bt').attr('disabled','disabled');
}
else {
// remove
$('#bt').removeAttr('disabled');
}
}
)
})
</script>
<input type="button" value="button" id="bt"/>
<input type="checkbox" id="ch"/>
