How do I uncheck the checkbox after modal dialog button is clicked?

Here's my problem:

Fiddle here: https://www.bootply.com/jMryRDRZNT

I need to display a warning message when a user clicks a checkbox. A modal dialog is then displayed where user can click 'I understand' and 'Cancel' When 'Cancel' button is clicked I want to uncheck the checkbox.

I try to do it this way:

$('#btnModalCancel').click(function() {
    $('chkImm').attr('checked', false);
});

tried also 'prop' instead of attr - still not working. It appears that after the dialog is displayed something is preventing the checkbox from changing. I placed console.log('test') inside the function - it is called, but the checkbox is not getting unchecked... See the fiddle in the link above.

I've use this one to Show the modal:

$('#myCheckbox').attr("checked", "checked");

but it' will not work if you're hiding the modal by this:

$('#myCheckbox').prop('checked', false);

So to show and hide properly, Both I'm using PROP method during Showing and Hiding.

$('#myCheckbox').prop('checked', false); //To Hide
$('#myCheckbox').prop('checked', false); //To Show

Your selector for chkImm is wrong, use #chkImm

For jQuery 1.6+ :

.attr() is deprecated for properties; use the new .prop() function instead as:

$('#myCheckbox').prop('checked', true); // Checks it
$('#myCheckbox').prop('checked', false); // Unchecks it

For jQuery < 1.6:

To check/uncheck a checkbox, use the attribute checked and alter that. With jQuery you can do:

$('#myCheckbox').attr('checked', true); // Checks it
$('#myCheckbox').attr('checked', false); // Unchecks it

Reference: https://stackoverflow.com/a/17420580/1715121

$('#chkImm').on('change', function() {
  if ($(this).is(':checked')) {
    $("#myModal").modal({
      backdrop: 'static',
      eyboard: false
    });
  }
});

$('#btnModalCancel').click(function() {
  $('#chkImm').attr('checked', false);
});

                            </button>

  1. Correct selector for checkbox will be $('#chkImm')
  2. Use prop to change checked state.
$('#chkImm').prop('checked', false);

Updated your code: https://www.bootply.com/GuRVklMhIa#

Try doing: document.getElementById("chkImm").checked = false;
