.checked = true) checkedClass: 'checked', // if not empty, used instead of 'checkedClass' option (input type specific) checkedCheckboxClass: '', checkedRadioClass: '', // if not empty, added as class name on unchecked state (input.checked = false) uncheckedClass: '', // if not ...

.checked = true) checkedClass: 'checked', // if not empty, used instead of 'checkedClass' option (input type specific) checkedCheckboxClass: '', checkedRadioClass: '', // if not empty, added as class name on unchecked state (input.checked = false) uncheckedClass: '', // if not ...
While using JavaScript for this task, we will be using the.checkedproperty. As it suggests itself, the checked property is used to check whether the selected radio button/checkbox is checked or not. If it is checked then the value is set to 'true' otherwise 'false'. ...
