如何基于来自Javascript的值以模态形式标记复选框？

Question

如何在Javascript的模态窗体上设置输入复选框的值？以下是我正在做的事情，但没有标记复选框。

我的Javascript :(复选框是安全帽，靴子和状态）

var $modal = $('#editJob');
$modal.find('input#jobTitle').val(thisJobObject.title);
$modal.find('input#payRate').val(thisJobObject.payrate);
$modal.find('input#startDate').val(thisJobObject.durationstart);
$modal.find('input#endDate').val(thisJobObject.durationend);
$modal.find('input#workingHours').val(thisJobObject.workinghrs);
$modal.find('input#location').val(thisJobObject.location);
$modal.find('input#experience').val(thisJobObject.experience);
$modal.find('input#hardhat').prop('checked', thisJobObject.hardhat);  //I tried this based on other posts but it did not work
$modal.find('input#boots').val(thisJobObject.boots);
$modal.find('input#other').val(thisJobObject.other);
$modal.find('input#status').val(thisJobObject.status);
$modal.find('textarea#description').val(thisJobObject.description);

模态形式（以玉为单位）：

#editJob.modal.fade(tabindex='-1', role='dialog', aria-labelledby='editJobLabel', aria-hidden='true')
          .modal-dialog#popupEditJob
            .modal-content#formEditJob(action='#', method='post', name='formEditJob')
              .modal-header#header
                button.close(type='button', data-dismiss='modal', aria-hidden='true', onclick='div_hide()') ×
                h4#label.modal-title Edit Job Details
              .modal-body
                #formBody(style='padding: 5px 20px;')
                  form#formFields.form-horizontal(data-parsley-validate='')
                    .form-group
                      label.col-sm-3.control-label(for='jobTitle')

我没有收到错误消息，代码编译得很好，但是没有标记复选框，即使在thisJobObject对象中标记了安全帽，引导和状态字段。

感谢您的帮助！
