I am new to jquery. I have below the code to find out whether the check box is checked or not. But though the check box is checked it always goes to else block in below the code:
if ($('#someId').is(':checked')) {
alert("checked");
} else {
alert("unchecked");
}
Html code:
By default the check box is not checked. The code is as below.
<td>
select :<br><input type="checkbox" id="someId" name="someId" value="">
</td>
Am I doing anything wrong here? Thanks!
try this:
select :<input type="checkbox" id="someId" name="someId" value="" checked />
<input id="btnSubmit" type="button" value="Submit"/>
$("#btnSubmit").on("click",function(){
if ($("#someId").is(':checked')) {
alert("checked");
} else {
alert("unchecked");
}
});

i hope it helps.
Skip jQuery's methods for this if you're only dealing with one checkbox: the DOM checked property is as easy as it could possibly be. jQuery only confuses the issue. Feel free to use jQuery to get hold of the element though.
var isChecked = $("#someId")[0].checked;
I am throwing out a guess that you need a doc ready function
$( document ).ready(function() {
$("#someId").on("click",function(){
if ($(this).is(':checked')) {
alert("checked");
} else {
alert("unchecked");
}
});
});`
see http://learn.jquery.com/using-jquery-core/document-ready/
if ($("#Your_CheckBox").is(':checked')) {
}

http://jsfiddle.net/1uvL7tcm/
$(document).ready(function () {
if ($('#plainText').is(':checked')) {
alert('checked');
}
});
What's wrong with my code? the alert doesn't get trigger.
Try http://jsfiddle.net/1uvL7tcm/3/
You need to bind to all checkbox elements change event as such:
$("input[type=checkbox]").change(function(){
if ($(this).is(":checked")){
alert('checked');
}
});
The code you have runs once, when the page loads. If your checkbox is checked by default, you will get the alert. I modified your jsFiddle to have it checked by default and you get the alert: http://jsfiddle.net/1uvL7tcm/2/
If what you're looking for is to have this code triggered anytime a checkbox is changed, you will have to add a change handler:
$('input[name="checkbox"]').change(function() {
if ($(this).is(':checked')) {
alert('checked');
}
});
In your case the checked condition is only checked once when the dom ready event is fired... what you need is to check the condition whenever the checked state is changed... for that you need to write a handler for the change event using change() method from jQuery.
Since you want the same handler to be fired for all checkboxes, you can use a common attribute among all the three checkboxes which is its name as a selector. So
$(document).ready(function () {
$('input[name="checkbox"]').change(function () {
if (this.checked) {
alert('checked: ' + this.value);
}
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<input type="checkbox" name="checkbox" id="plainText" value="status">
<label for="plainText">Status</label>
<input type="checkbox" name="checkbox" id="image" value="Images">
<label for="image">Images</label>
<input type="checkbox" name="checkbox" id="video" value="Video">
<label for="video">Video</label>
Try This..
$('#plainText').on('click',function(){
if ($('#plainText').is(':checked')) {
alert('checked');
}
});
Try this...
$(document).ready(function(){
$("input[type=checkbox]").change(function(){
if ($("#plainText").is(":checked")){
alert('checked');
}
});
});
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 have a radio button selection that jquery is able to loop through them and read the values for each one just fine, but jquery can only detect when one of them has been selected. When selecting the other one, jquery just ignores it and tells me none have been selected.
jquery:
$('[name="banner_type"]').each(function() {
console.log($(this).val());
if($(this).is(':checked')) {
valid = $(this).val();
return valid;
} else if(!$(this).is(':checked')) {
valid = false;
}
});
html:
<input type="radio" id="upload" name="banner_type" value="upload" />
<input type="radio" id="html" name="banner_type" value="html" />
"upload" is being ignored by jquery, "html" is not
Im doing it this way:
valid=false;
$('[name="banner_type"]').each(function() {
if($(this).is(':checked'))
valid = $(this).val();
});
So each time You check for radio being checked, valid value is renewed.
here's fiddle for You. Function "check" checks validity, returning false if none is selected.
http://jsfiddle.net/CLaDG/
The else part is setting value for valid but not returning it. Also the value is always false for second radio button. Try this:
$('[name="banner_type"]').each(function() {
console.log($(this).val());
if($(this).is(':checked')) {
valid = $(this).val();
return valid;
} else if(!$(this).is(':checked')) {
valid = $(this).val();
return valid;
}
});
This can be written shorter and better but right now I am just fixing the issue I see.
not sure which version of jQuery you are on, but try using jQuery.prop as well as delegated event on the container might be cleaner, such as:
$('.your-radios-container').on('change','[name="banner_type"]',function(){
valid = $(this).prop('checked');
});
I have forked your fiddle to show you how it could work:

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 have a page that has a number of checkboxes in it. I would like to write a function that will be called when the ckeckbox is clicked, that determines if the checkbox is checked or not.
<input type="checkbox" onclick="toggleVis('id', this);"/> ID
<input type="checkbox" onclick="toggleVis('edit', this);" checked="checked"/> Edit
<input type="checkbox" onclick="toggleVis('last', this);"/> Last
Note some checkboxes start checked.
I figured that there must be a way to do this based on a reference passed, so I passed the this value as a parameter.
function toggleVis(name, checkbox)
{
//if(checkbox.checked())
console.log('checked');
if($('.'+name).css('display') != "none")
$('.'+name).css('display', 'none');
else
$('.'+name).css('display', 'table-cell');
}
I am open to use jQuery.
You were close.
if(checkbox.checked) {
console.log('checked');
//...
}
There's no checked() method, but there is a checked property. Note that your code may only work on clicks. Perhaps onchange would be better?
Look at the checkboxobj.checked property (instead of calling it like a function). In your case, you could reference if (checkbox.checked) { ... }. More information can be found on this website
If you wanted to do this with jQuery you might try the following. Note that I'm binding to the checkbox instead of including the 'onclick' or 'onchange' directly on the HTML element.
$('[type=checkbox]').click(function(){
if( $(this).attr('checked') ){
console.log('checked');
if($('.'+$(this).attr('name')).css('display') != "none") {
$('.'+$(this).attr('name')).css('display', 'none');
} else {
$('.'+$(this).attr('name')).css('display', 'table-cell');
}
}
});
And a JQuery-based solution:
var checked = $(checkbox).is(':checked');
Helpful if you want to find the checkbox first by some JQ selector.
<input type="checkbox" class="checkthis"> ID
<input type="checkbox" class="checkthis" checked="checked"> Edit
<input type="checkbox" class="checkthis"> Last
$(input.checkthis).click(function() {
if($(this).is(':checked') {
// do checked stuuf
} else {
// do not checked stuff
}
});
