Get checkbox list values with jQuery

Question

In a div, I have some checkbox. I'd like when I push a button get all the name of all check box checked. Could you tell me how to do this ?

<div id="MyDiv"> .... <td><%= Html.CheckBox("need_" + item.Id.ToString())%></td> ... </div> 

Thanks,

Answer 1

$(document).ready(function() {     $('#someButton').click(function() {         var names = [];         $('#MyDiv input:checked').each(function() {             names.push(this.name);         });         // now names contains all of the names of checked checkboxes         // do something with it     }); });

Since nobody has mentioned this..

If all you want is an array of values, an easier alternative would be to use the .map() method. Just remember to call .get() to convert the jQuery object to an array:

Example Here

var names = $('.parent input:checked').map(function () {     return this.name; }).get();  console.log(names); 

var names = $('.parent input:checked').map(function () {      return this.name;  }).get();    console.log(names);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <div class="parent">      <input type="checkbox" name="name1" />      <input type="checkbox" name="name2" />      <input type="checkbox" name="name3" checked="checked" />      <input type="checkbox" name="name4" checked="checked" />      <input type="checkbox" name="name5" />  </div>

Pure JavaScript:

Example Here

var elements = document.querySelectorAll('.parent input:checked'); var names = Array.prototype.map.call(elements, function(el, i) {     return el.name; });  console.log(names); 

var elements = document.querySelectorAll('.parent input:checked');  var names = Array.prototype.map.call(elements, function(el, i){      return el.name;  });    console.log(names);

<div class="parent">      <input type="checkbox" name="name1" />      <input type="checkbox" name="name2" />      <input type="checkbox" name="name3" checked="checked" />      <input type="checkbox" name="name4" checked="checked" />      <input type="checkbox" name="name5" />  </div>
