如何使用jQuery重置选择的多选字段？ [英] How do you reset a Chosen multiple select field using jQuery?

问题描述

我有一个带有多个选择字段的表单，使用Formtastic和Chosen创建。

I have a form with a multiple select field, created using Formtastic and Chosen.

此表单有一个多选字段，这里是rails代码：

This form has a multiple select field, here is the rails code for it:

 = semantic_form_for 'post', :url => action_name_post_path(@post), :html => {:method => :put}, :remote => true do |f|
    = f.input :blogs, :label => _("Blog"), :as => :select, :multiple => :true, :input_html => {:class => "chzn-select"}, :collection => Blog.all

我想使用jQuery重置输入字段（表单已提交并远程重置），我似乎无法弄清楚如何删除所选元素//清除输入字段。问题是选择更改输入字段，因此它不是一个简单的文本区域。

I would like to reset the input field using jQuery (the form is submitted and reset remotely), and I can't seem to figure out how to remove the selected elements//clear the input field. The issue is that chosen changes the input field so it isn't a simple text area.

有人能指出我正确的方向吗？

Can anyone point me in the right direction?

推荐答案

试试这个

$('.chzn-select').val('').trigger('liszt:updated');
