Getting multiple checked checkbox labels into an array

Question

I am hoping to get all the checked checkboxes from my form into an array.

Here is what I did.

$("div.category-panel input:checked").next ('label').text(); perfectly gets all the checked checkboxes but it just shows them together as one text. As an example, checkbox1, checkbox2 and checkbox3 (if checked) would show as checkbox1checkbox2checkbox3.

I was hoping to get these different checkboxes in an array so that I can use them.

    $('.submit').on("click", function(e) {

    //got all checked checkboxes into 'children'.            
    children = $("div.category-panel input:checked").next ('label').text();

    //Put in array.            
    var array = [];
    var i = 0;
    $.each(children, function(key, value){
        array.push($(this).text());
    });

    //Show the array.
    for (var i = 0; i < array.length; i++) {
      console.log(array[i]);
    }

 });

HTML, just in case is:-

<div class="category-panel">

<input type="checkbox" name="name_service2" id="tid-46" value="46" checked="checked"> <label class="option" for="edit-tid-46">CheckBox1</label>

<input type="checkbox" name="name_service3" id="tid-47" value="47" checked="checked"> <label class="option" for="edit-tid-47">CheckBox2</label>

<input type="checkbox" name="name_service4" id="tid-44" value="44" checked="checked"> <label class="option" for="edit-tid-44">CheckBox3</label>

<input type="checkbox" name="name_service5" id="tid-48" value="48" checked="checked"> <label class="option" for="edit-tid-48">CheckBox4</label>

</div>

You can use .map() like

 $('.submit').on("click", function (e) {

     //got all checked checkboxes into 'children'.            
     var array = $("div.category-panel input:checked").next('label').map(function(){
         return $(this).text();
     }).get();

     //Show the array.
     for (var i = 0; i < array.length; i++) {
         console.log(array[i]);
     }

 });

$('.submit').on("click", function(e) {

   //got all checked checkboxes into 'children'.            
   var array = $("div.category-panel input:checked").next('label').map(function() {
     return $(this).text();
   }).get();

   //Show the array.
   for (var i = 0; i < array.length; i++) {
     console.log(array[i]);
   }

 });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="category-panel">
  <input type="checkbox" name="name_service2" id="tid-46" value="46" checked="checked" />
  <label class="option" for="edit-tid-46">CheckBox1</label>
  <input type="checkbox" name="name_service3" id="tid-47" value="47" checked="checked" />
  <label class="option" for="edit-tid-47">CheckBox2</label>
  <input type="checkbox" name="name_service4" id="tid-44" value="44" checked="checked" />
  <label class="option" for="edit-tid-44">CheckBox3</label>
  <input type="checkbox" name="name_service5" id="tid-48" value="48" checked="checked" />
  <label class="option" for="edit-tid-48">CheckBox4</label>
</div>
<button class="submit">submit</button>

In your case children is a string, which contains the concatenated text of all label's which are next siblings of checked checkboxes

you need to use .map() function to get the all labels text as object. then use .get() to get them in array:

$("div.category-panel input:checked").next('label').map(function(){
    return $(this).text();
}).get();// ["checkbox1","checkbox2" ,"checkbox3"]

If you want them as comma separated values, use .join() after .get()

$("div.category-panel input:checked").next('label').map(function(){
  return $(this).text();
}).get().join();//  "checkbox1, checkbox2 ,checkbox3"

   <input type="checkbox" name="name_service2" id="tid-46" value="46" checked="checked" /> <label class="option" for="edit-tid-46">A Value</label>

   <input type="checkbox" name="name_service3" id="tid-47" value="47" checked="checked" /> <label class="option" for="edit-tid-47">A Value</label>

   <input type="checkbox" name="name_service4" id="tid-44" value="44" checked="checked" /> <label class="option" for="edit-tid-44">A Value</label>

   <input type="checkbox" name="name_service5" id="tid-48" value="48" checked="checked" /> <label class="option" for="edit-tid-48">A Value</label>

$('.submit').on("click", function(e) {
    //got all checked checkboxes into 'children'.            
    children = $("div.category-panel input:checked").next ('label');

    //Put in array.            
    var array = [];
    $.each(children, function(){
        array.push($(this).text());
    });

    //Show the array.
    $(array).each(function(){
        console.log(this.toString());
    });

 });
