}
解决方案
这可以删除给定 select
元素的所有 optgroup
子项:
标记:
< select id =mySelect>
< optgroup label =MyGroup>< / optgroup>
< option>选项< / option>
< option>选项< / option>
< option>选项< / option>
< option>选项< / option>
< optgroup label =MyGroup2>< / optgroup>
< option>选项< / option>
< option>选项< / option>
< option>选项< / option>
< / select>
jQuery:
code> $(function(){
$(#mySelect)。children()。remove(optgroup);
});

All I was attempting was to edit some old code, where I had made an option group, but now I'd like to take it away. I can't just do it with css because it's using the chosen plugin.
function flavorChooser (title, item) {
var title = 'hidden';
var optgroup = jQuery('<optgroup display="' + title + '"/>');
jQuery.each(item, function(sub_title, sub_item) {
if (typeof sub_item[0] !== "undefined") {
var opt = jQuery('<option value="' + sub_item[0] + '" data-store-locator-value="' + sub_item[0] + '">' + sub_title + '</option>');
optgroup.prepend(opt);
}
});
// console.log('chozen ');
// jQuery('.chzn-container .chzn-results .group-result').css('display', 'none');
return optgroup;
}
解决方案
This works to remove all of the optgroup
children of a given select
element:
Markup:
<select id="mySelect">
<optgroup label="MyGroup"></optgroup>
<option>Option</option>
<option>Option</option>
<option>Option</option>
<option>Option</option>
<optgroup label="MyGroup2"></optgroup>
<option>Option</option>
<option>Option</option>
<option>Option</option>
</select>
jQuery:
$(function () {
$("#mySelect").children().remove("optgroup");
});
