You can use the following function to get all of the checkboxes that are within a designated parent area.

function getCheckboxes(parent) {
    parent = parent || document;
    var inputs = parent.querySelectorAll('input'),
        checkboxes = [];
    for (i = 0; i < inputs.length; i += 1) {
        if (inputs[i].type.toLowerCase() === 'checkbox') {
    return checkboxes;

Hi svibuk,

I assume you want a functionality similar to select all and deselect all.

If it is not complicated for you then you can go through below steps.

(Consider it for one tab, you can implement the same for other tabs as well)

  1. In the first column of your grid you will be having the checkboxes.
  2. Add a class to all the checkboxes appearing in the first column
  3. Through jquery you can change the status of those checkboxes using that class name
