checkbox being checked on false - jquery

Question

$('#checkyes').prop('checked', row['checkb']);
var check = row['checkb'];
alert(check);
$('#checkyes').checkboxradio('refresh');

The alert correctly shows the value inside row['checkb'] to be false, yet the checkbox gets ticked anyway. Am I missing some quotations somewhere or can I not use the row value?

Answer 1

 var isResult = (row['checkb'] == 0) ? false : true; 
 $('#checkyes').prop('checked', isResult);

  $('#checkyes').prop('checked', JSON.parse(row['checkb']));

Answer 2

Try

$('#checkyes').prop('checked', (row['checkb'] == 'true') ? true : false);

Or

$('#checkyes').prop('checked', (row['checkb'] == 'true') );

Or

 var chk = (row['checkb'] == 'true') ? true : false; //Or var chk = (row['checkb'] == 'true'); $('#checkyes').prop('checked', chk );

Problem

row['checkb'] has value string true or false not Boolean value .

So $('#checkyes').prop('checked', row['checkb']); will evaluate to checked.

String value here prop('checked', String) makes it true for all cases .

Answer 3

根据Tushar Gupta的回答，我建议：

$('#checkyes').prop('checked', row['checkb'] == 'true');
