jQuery 1.4.4 - issue with attr('selected', null)
- by Renso
Issue:
The code below worked before under version jQuery 1.4.2 but when I upgraded to version 1.4.4 it no longer worked as expected - it did not unselect the list box item, only setting "selectd" worked:
_handleClick: function(elem) {
var self = this; var initElem = this.element;
var checked = $(elem).attr('checked');
var myId = elem.attr('id').replace(initElem.attr('id') + '_chk_', '');
initElem.children('option[value=' + myId + ']').attr('selected', function() {
if (checked) {
return 'selected';
} else { return null; }
});
if ($.isFunction(self.options.onItemSelected)) {
try {
self.options.onItemSelected(elem, initElem.children('option').get());
} catch (ex) {
if (self.options.allowDebug)
alert('select function failed: ' + ex.Description);
}
}
},
Solution:
Under jQuery 1.4.4 you need to explicitly remove the attribute as in "removeAttr('selected'):
_handleClick: function(elem) {
var self = this; var initElem = this.element;
var checked = $(elem).is(':checked');
var myId = elem.attr('id').replace(initElem.attr('id') + '_chk_', '');
if (checked) {
initElem.children('option[value=' + myId + ']').attr('selected', 'selected');
} else {
initElem.children('option[value=' + myId + ']').removeAttr('selected');
}
if ($.isFunction(self.options.onItemSelected)) {
try {
self.options.onItemSelected(elem, initElem.children('option').get());
} catch (ex) {
if (self.options.allowDebug)
alert('select function failed: ' + ex.Description);
}
}
},
