Tips for placing a checkbox above a DIV element when generating checkboxes within a foreach loop

This is the output I have generated

This HTML code belongs to me

    <td class="category" colspan ="2" id="tdcategory1">
         <div id="category1" style="border:none !important; overflow:hidden; width:auto; height:auto">
         </div>
    </td>

My procedure involves creating a checkbox inside the id="tdcategory1" and creating multiple checkboxes inside the id="category1"

This is my JavaScript code

     var div = $('#tdcategory1');
     var input = $('<input />', { type: 'checkbox', name: "chkallcategory1", id: "chkallcategory1", value: 1, style: "cursor:pointer" });
     input.appendTo(div);

     $.each(data.Records, function (e, key, value) {
      var div = $('#category1');
           var input = $('<input />', { type: 'checkbox', name: cate_name, id: cate_name + '_' + key.id, value: key.id, style: "cursor:pointer" });
         input.appendTo(div);
     });

The issue I am facing is that the first checkbox I create is positioned at the bottom of the #category1 div

Answer №1

To add an input element to a specified div element, you can use the prependto() method.

var targetDiv = $('#tdcategory1');
 var newInput = $('<input />', { type: 'checkbox', name: "chkallcategory1", id: "chkallcategory1", value: 1, style: "cursor:pointer" });
 newInput.prependTo(targetDiv);

Answer №2

While performing the appendTo function for the initial checkbox, it will generate the following code snippet on your webpage:

<td class="category" colspan ="2" id="tdcategory1">
         <div id="category1" style="border:none !important; overflow:hidden; width:auto; height:auto">
         </div>
         <!-- checkbox here -->
</td>

Therefore, it is recommended to insert it before the category1 div.

Approach #1

To achieve this, utilize the insertBefore method as shown below:

var div = $('#category1');
var input = $('<input />', { type: 'checkbox', name: "chkallcategory1", id: "chkallcategory1", value: 1, style: "cursor:pointer" });
input.insertBefore(div);

$.each(data.Records, function (e, key, value) {
  var div = $('#category1');
  var input = $('<input />', { type: 'checkbox', name: cate_name, id: cate_name + '_' + key.id, value: key.id, style: "cursor:pointer" });
  input.appendTo(div);
});

Approach #2

If you lack access to the element and wish to add it at the beginning, consider using prependTo like this:

var div = $('#tdcategory1');
var input = $('<input />', { type: 'checkbox', name: "chkallcategory1", id: "chkallcategory1", value: 1, style: "cursor:pointer" });
input.prependTo(div);

$.each(data.Records, function (e, key, value) {
  var div = $('#category1');
  var input = $('<input />', { type: 'checkbox', name: cate_name, id: cate_name + '_' + key.id, value: key.id, style: "cursor:pointer" });
  input.appendTo(div);
});
