I used checkbox in two items now I can get the value of the second group of checkbox.
The first group of checkbox I use:
<input name="option" type="checkbox" value="1" id="option1">option 1
<input name="option" type="checkbox" value="2" id="option2">option 2
Then
<input name="choice" type="checkbox" value="1" id="choice1">choice 1
<input name="choice" type="checkbox" value="2" id="choice2">choice 2
How can i get the value of selected checkboxes, in each group it is only allowed to select 1 checkbox.
I just need the javascript function
You want a radio button, (where only one option can be selected at a time)
<input name="option" type="radio" value="1" id="option1">option 1
<input name="option" type="radio" value="2" id="option2">option 2
Checkboxes can be grouped into arrays by appending [] to the end of their names:
<input name="option[]" type="checkbox" value="1" id="option1">option 1
<input name="option[]" type="checkbox" value="2" id="option2">option 2
This will not get the effect you want, it will instead group the checkboxes so that all input from them will result in one array. it is still possible to select multiple checkboxes with this method.
You can use this following codes to get the value of the checkbox if you are using multiple checkboxes.
$('input[name=option]:checked').val();
And retrieve the value of radio button as
document.formName.radioboxName.value;
Since you are giving same name for the radio buttons, only one value can be selected.
Katherine if you want to select a single item from both the groups then you should go for the radio other wise you can not restrict to select only one check box and unnecessary you have to write a bulk of worth less code for that.
Also you have to mention the array of check boxes. the syntax you have taken is wrong the correct one is
<input name="option[]" type="checkbox" value="1" id="option1">option 1
<input name="option[]" type="checkbox" value="2" id="option2">option 2
and for radios
<input name="option" type="radio" value="1" id="option1">option 1
<input name="option" type="radio" value="2" id="option2">option 2
With Jquery
var checked;
$("input").each(function () {
if ($(this).is(':checked'))
checked[ $(this).attr("name")] = $(this).attr("value")
})
//checked is an array/object with all your checked checkboxs
No jQuery Pure Javascript
const checkedArr = Array.from(
document.querySelectorAll(`input[name=myCheckboxGroup]:checked`)).map(node=>node.value);

I have these 4 checkboxes and I want to find them in jQuery by their names.
Is there any way to find all 4 checkboxes by their name?
<input type="checkbox" value="1" id="RangeFlexionRightSide1" name="RangeFlexionRightSide">
<input type="checkbox" value="2" id="RangeFlexionRightSide2" name="RangeFlexionRightSide">
<input type="checkbox" value="1" id="ManualFlexionRightSide1" name="ManualFlexionRightSide">
<input type="checkbox" value="2" id="ManualFlexionRightSide2" name="ManualFlexionRightSide">
I am trying these below codes but I didn't get the result:
$("input[name^='Range Manual']").length
$("input[name^='Range,Manual']").length
$("input[name^='Range'][name^='Manual']").length
Yes you could use the ending by selector $= like :
$("input:checkbox[name$='FlexionRightSide']").length
Or using start with selctor ^= like :
$("input:checkbox[name^='Range'],input:checkbox[name^='Manual']").length
NOTE : You could give them a common class, and select them easely using class selector . like :
$('.common_class').length
console.log($("input:checkbox[name$='FlexionRightSide']").length); //4
console.log($("input:checkbox[name^='Range'],input:checkbox[name^='Manual']").length); //4
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" value="1" id="RangeFlexionRightSide1" name="RangeFlexionRightSide">
<input type="checkbox" value="2" id="RangeFlexionRightSide2" name="RangeFlexionRightSide">
<input type="checkbox" value="1" id="ManualFlexionRightSide1" name="ManualFlexionRightSide">
<input type="checkbox" value="2" id="ManualFlexionRightSide2" name="ManualFlexionRightSide">
You can do that with *= which will check if name contains value passed.
Or you can do as your way with ^= as shown below.
In jQuery selectors
[name^='Range'] - Here ^= find element whose name starts with Range.
[name$='Range'] - Here $= find element whose name ends with Range.
[name*='Range'] - Here *= find element whose name contains Range.
Find more about jQuery Selector here.
console.log($("input[name^='Range'], input[name^='Manual']").length);
console.log($("input[name*='RightSide']").length);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" value="1" id="RangeFlexionRightSide1" name="RangeFlexionRightSide">
<input type="checkbox" value="2" id="RangeFlexionRightSide2" name="RangeFlexionRightSide">
<input type="checkbox" value="1" id="ManualFlexionRightSide1" name="ManualFlexionRightSide">
<input type="checkbox" value="2" id="ManualFlexionRightSide2" name="ManualFlexionRightSide">
I guess this is what you need:
$("input[name^='Range'],input[name^='Manual']").length
I need better validation logic, where some Checkboxes and some input fields are grouped together.
The user either have to check at least one checkbox or have to fill at least one input box.
If a checkbox is checked or an input field is filled then the complete group is validated.
What will be the best possible way to validate such a situation?
e.g
<input class="checkbox" type="checkbox" name="check-deal" value="1" grouped="deal" >
<input class="checkbox" type="checkbox" name="check-deal" value="2" grouped="deal">
<input class="checkbox" type="checkbox" name="check-deal" value="3" grouped="deal">
<input class="checkbox" type="checkbox" name="check-deal" value="4" grouped="deal">
<input class="input-group" type="text" name="deal-name1" value="" grouped="deal">
<input class="input-group" type="text" name="deal-name2" value="" grouped="deal">
I have defined an extra attribute grouped for all input and checkboxes that should be grouped togather
but getting no idea how to validate the group as best practice.
DEMO
Point No.1 : There isn't any attribute called grouped for html as of my knowledge but I would suggest you to use data-* prefixed attribute names like data-grouped or data-anyname which is valid
Point No.2 : I rather categorized your checkboxes and textboxes into separate divs and below is how it is:
<div class="chkbox">
<input class="checkbox" type="checkbox" name="check-deal" value="1" />
<input class="checkbox" type="checkbox" name="check-deal" value="2" />
<input class="checkbox" type="checkbox" name="check-deal" value="3" />
<input class="checkbox" type="checkbox" name="check-deal" value="4" />
</div>
<div class="txtbxs">
<input class="input-group" type="text" name="deal-name1" value="" />
<input class="input-group" type="text" name="deal-name2" value="" />
</div>
<button class="btnValidate">Validate</button>
Point No.3 : Below is how you can validate using jquery
$('.btnValidate').on('click',function(){
var chkLength=$('.chkbox .checkbox:checked').length; //get checkbox checked length
var filledText=$(".txtbxs .input-group").val()!="";
//get bool value whether any of the text box is filled or not
if(chkLength || filledText) //check with or condition
alert('valid')
else
alert('invalid');
});
UPDATE
DEMO
As #AkshatG pointed in his answer the discrepancy was there in my answer so I've edited it and here is the updated solution.
$('.btnValidate').on('click',function(){
var chkLength=$('.chkbox .checkbox:checked').length;
var filledText=false; //First set it to false
$.each($(".txtbxs .input-group"),function(index,value){
if($(value).val()!="")
{
filledText=true//if it finds any value then set it to true
return;//break from $.each
}
})
if(chkLength || filledText)
alert('valid')
else
alert('invalid');
});
You first need to take count of each validations. And then check if any of the two has count greater than 0 or not. Guruprasad's answer won't work if you enter text on second textbox because it won't filter all the textboxes. You have to use filter function for this :
$("input[type='text'],textarea").filter(function() {
return $(this).val() != "";
}).length;

Hope this helps.
I have 3 different Radio Buttons in a page with the following code
<input type="radio" name"1" value="1">1</input>
<input type="radio" name"2" value="2">2</input>
<input type="radio" name"3" value="3">3</input>
How can I get the value of the selected radio button with different names ?
I tried
var option = $("input[type='radio'][name='1']:checked").val();
But giving Undefined. Any Idea's ?
You need to have them be the same name, otherwise they don't work as radios (they could all be selected), and you need your html to be valid:
<input type="radio" name="1" value="1">1
<input type="radio" name="1" value="2">2
<input type="radio" name="1" value="3">3
You're missing the = when assigning the name attribute.
<input type="radio" name="1" value="1" />
<!-- ^
Also, as others have pointed out in comments, input tags are self-closing. (although it does work even with invalid html)
Demo: http://jsfiddle.net/g7RT2/
You missed "=" sign after the "name" attribute, selector doesn't match name=1 condition: <input type="radio" name"1" value="1">1</input>
http://jsfiddle.net/gLgBj/
here is a working fiddle
http://jsfiddle.net/mW7mk/
your html is not well formated, the input is self closed and name="1" not name"1"
var options = $("input[type='radio'][name='1']:checked").val();
alert("test : " + options);
worked just fine with :
<label><input type="radio" name="1" value="1" checked="checked"/>1</label>
<label><input type="radio" name="2" value="2"/>2</label>
<label><input type="radio" name="3" value="3"/>3</label>
I have a set of checkboxes that have a name like
form[check][..]
where .. is a number (id). I would have another checkbox that checked would check all the previous checkboxes, a sort of check/uncheck all. The problem is, how can with jQuery get all that checkboxes?
EDIT 1
this is my current html markup:
<input type="checkbox" value="1" name="form[check][1]" />
<input type="checkbox" value="1" name="form[check][2]" />
<input type="checkbox" value="1" name="form[check][3]" />
<input type="checkbox" value="1" name="form[check][..]" />
<input type="checkbox" name="checkAll" />
Add a class to the checkboxes you want checked, and select them using that class
$('.myCheckbox').prop('checked', true);
$('[name="checkAll"]').on('change', function(){
$('input[name^="form[check]"]:checkbox').prop('checked', $(this).prop('checked'));
});
