jQuery滑动切换帮助 [英] Jquery sliding toggle help

问题描述

大家好，
我陷入了一个问题.我已使用此jQuery代码以滑动效果切换2个div:

Hello everyone,
I am stuck with a problem. I have used this jQuery code for toggling 2 divs with a slide effect:

<script type=text/javascript>
    $(document).ready(function() {
        //hide the all of the element with class msg_body
        $(".msg_body", "litCategoryName").hide();
        //toggle the componenet with class msg_body
        $(".msg_head").click(function() {
            $(this).next(".msg_body").slideToggle(50);
        });
    });
</script>

它工作正常，但当有人展开和折叠2个div时，我也想显示+或-.
谁能指导我如何实现这一目标.

It''s working fine, but I want to display a + or - too when someone expands and collapses the 2 divs.
Can anyone guide me on how to achieve this.

Thanks in advance!

推荐答案

(document).ready(function(){ //使用msg_body

(document).ready(function() { //hide the all of the element with class msg_body

(.msg_body"，"litCategoryName").hide();隐藏所有元素. //使用类msg_body

(".msg_body", "litCategoryName").hide(); //toggle the componenet with class msg_body

(.msg_head").click(function(){

(".msg_head").click(function() {
