jQuery Select All Checkbox; Deselect parent when child checkbox unchecked

89 views Asked by At

I've created a JSFiddle. When viewing it, check a parent and you'll see the children are selected. Ideally, when a child is deselected, I'd like for the parents to become unchecked, this could be one or two parents depending on what was deselected (the parent are to act as a select all for the children beneath it).

I'm not sure of the best way to do to accomplish due to the nesting.

$("input[type='checkbox']").change(function() {
  $(this).siblings()
    .find("input[type='checkbox']")
    .prop('checked', this.checked);
});
#listContainer {
  /*width:400px;*/
  width: 100%;
}

  list-style: none;
  padding: 0;
  margin: 0;
}

I've included the JS code below but to get the full picture, please visit the JSFiddle.

$("input[type='checkbox']").change(function() {
  $(this).siblings()
    .find("input[type='checkbox']")
    .prop('checked', this.checked);
});

I also tried this but it unchecks all the same-level items as well:

$("input[type='checkbox']").change(function() {
  if ($(this).is(':checked')) {
    $(this).siblings()
      .find("input[type='checkbox']")
      .prop('checked', this.checked);
  } else {
    $(this).parents()
      .find("input[type='checkbox']")
      .prop('checked', this.checked);
  }
});

Edit: As per the comment, use a recursive function would solve the problem.

let checkbox = "input[type='checkbox']";

$(checkbox).change(function() {
  let $this = $(this);
  CheckChildren($this);
  CheckParents($this);
});

let CheckChildren = function($this) {
  $this.siblings()
    .find(checkbox)
    .prop('checked', $this.is(":checked"));
}

let CheckParents = function($this) {
  let $parent = $this.parent().parent();
  if($parent.length == 0) return;
  // get the number of all checkboxes that $parent contains
  // get the number of checked checkboxes that $parent contains
  // if the two numbers equals, this checkbox($parent.siblings(checkbox)) should be checked.
  let checked = $parent.find(checkbox).length
            === $parent.find(`${checkbox}:checked`).length;
            // this is "template strings"
            // `${checkbox}:checked` = checkbox + ":checked"
  CheckParents($parent.siblings(checkbox).prop("checked", checked));
}

I find the easiest way to do this is to just add an ID to the parent (which I see you already have) and then let the children know who their parent is via a data attribute. It keeps it simple. Might not be workable for you if you don't have visibility at that level of the code though.

The html would be something like:

<input type="checkbox" name="phase" id="phase_cb_1" class='one'> Phase 1
<input type="checkbox" name="week" id="week_cb_1" class='one'> Week 1
<input type="checkbox" name="day" id="day_cb_1" data-parent='week_cb_1' data-parents-class='one'> Day 1

Then the jquery would just add a little to what you already have:

$("input[type='checkbox']").change(function() {
if ($(this).is(':checked')) {
   $(this).siblings()
     .find("input[type='checkbox']")
     .prop('checked', this.checked);
  } else {
     var parentId = $(this).data('parent');
     $("#"+parentId).prop('checked', this.checked);
     // Or if you want all parents:
     var parentsClasses = $(this).data('parents-classes');
     $("."+parentsClasses).prop('checked', this.checked);
  }
});

This would uncheck a single parent. If you wanted to be able to uncheck multiple parents, you can apply the same logic, but use classes instead of ids... or a combination of both.
