Select all textboxes using jQuery

Question

I have code which displayed a person's info in a table(fields:name, surname, address, etc.) and one of the inputs is a checkbox. The code is as follows:

  $("#table").append('<tr class="trow'+j+'">'+
                      '<td class="ids" id="z'+i+'">'+totrecs+'</td>'+
              '<td>'+member[i].jdate+'</td>'+
              '<td class="users" 

              '<td id="contact'+i+'">'+member[i].fname+' '+member[i].lname+'</td>'+
              '<td id="myaddress'+i+'">'+member[i].address1+' '+member[i].town+'</td>'+

              '<td><input type="checkbox" name="whome" id="showMe'+i+'"'+
                                             'class="boxes" onclick="getMe('+i+')" /></td></tr>');  
      totrecs++;
      j++;
     }

What I am tryin to do is program a function that when clicking a certain button all of the checkboxes will be selected/checked.

I would appreciate any help. Thank You.

Answer 1

<input type="button" value="Check/Uncheck All" />

$('#btnId').on('click', function() {

    var check = false;

    if( !$(this).hasClass('checked')){
        bool = true;
    }

    $(this).toggleClass('checked');

    $('#table input[type="checkbox"]').prop('checked', check)
});

To check all checkboxes in #table using jQuery:

$('#table :checkbox').attr('checked', '');

Note that this will not trigger any click events you set for the checkboxes. You should use the change event instead of click to make it happen as expected.
