[英]jquery cloning select box without selected option
Need to clone select box from previous one ( ie, add select box 'n' number of time from the previous one ) But when I added each time, all the previously selected options should not be available in the cloned select box list. 需要从上一个克隆选择框(即,从前一个添加选择框'n'的次数)但是,当我每次添加时,所有先前选择的选项在克隆的选择框列表中都不可用。
$('.field_select_box_list').each(function(){
$(this).find('option:selected').remove();
});
This code removes the parent select boxes selected option too.. but I want remain them to have the selected option. 这段代码也删除了父选择框的选定选项。.但是我希望保留它们具有选定的选项。
any help. 任何帮助。
Your clone code can just do something like 您的克隆代码只能做类似的事情
$('el').clone().find('option:selected').remove().end()
The .end()
causes the selector to return to being $('el')
rather than the filtered option:selected
selector, so you can continue running things like .appendTo()
etc without needing to break the chain. .end()
会使选择器返回到$('el')
而不是已过滤的option:selected
选择器,因此您可以继续运行.appendTo()
类的东西而无需打断链。
I think you need use one select_box original , hidden it. 我认为您需要使用一个select_box original ,将其隐藏。 Then you can remove with select_box second not hidden or add more element from select_box original .
然后,您可以使用select_box第二个未隐藏的元素删除它,或者从select_box original添加更多元素。
