[英]Jquery Activate on DropDownList/SELECT item changed
I have some JQuery code that filters out a list of links on the page. 我有一些JQuery代码可以过滤出页面上的链接列表。 At present the filtering is fired when a link wih a blind href is clicked.
当前,当单击带有盲href的链接时,将触发过滤。 The id of the link is taken to determine which content remains visible on the page.
链接的ID用于确定哪些内容在页面上保持可见。 EG:
例如:
<script type="text/javascript">
$(document).ready(function () {
//when a link in the filters div is clicked...
$('#filters a').click(function (e) {
//prevent the default behaviour of the link
e.preventDefault();
//get the id of the clicked link(which is equal to classes of our content
var filter = $(this).attr('id');
//show all the list items(this is needed to get the hidden ones shown)
$('#content ul li').show();
/*using the :not attribute and the filter class in it we are selecting
only the list items that don't have that class and hide them '*/
$('#content ul li:not(.' + filter + ')').hide();
});
});
I need to changed this so that, the JQuery is activated when an option is changed in a DropDownList/SELECT. 我需要对此进行更改,以便在DropDownList / SELECT中更改选项时激活JQuery。 However, I cant quite get my head around how to change this JScript to detect the selection in the DDL rather than a hyperlink.
但是,我不太了解如何更改此JScript来检测DDL中的选择,而不是超链接。
Any help would be greatly appreciated. 任何帮助将不胜感激。
Thanks. 谢谢。
Use the change() event 使用change()事件
$("#idOfDropDown").change(function() {
//code here
var filter = this.value //gets the value of the selected dropdown item.
});
This will fire each time a dropdown selection has been made. 每次选择下拉菜单时都会触发。
