使用Java显示/隐藏tr [英] To show/Hide tr using Javascript

问题描述

嗨

编写以下Javascript来显示和隐藏tr区域，但是当其触发时，tr区域将再次打开和关闭.

如果错误，请更正我的代码.

Hi

The following Javascript is written to show and hide a tr region but when its firing the tr region opens and closes again.

Kindly correct my code if wrong .

function ShowHide() {
           var trid = document.getElementById("tr_View_Filter_Template_List");
           if (trid != null) {
               if (trid.style.display == "block") {
                   trid.style.display = 'none';
               }
               else {
                   trid.style.display = 'block';
               }
           }
       }

调用Java脚本的C#代码

lnView_Filter_Template_List.Attributes.Add(General_Constants.onclick，"ShowHide();");

C# Code to Call Javascript

lnView_Filter_Template_List.Attributes.Add(General_Constants.onclick, "ShowHide();");

推荐答案

我看不到您的代码有任何问题，可能是该函数以某种方式被连续两次调用.在您的函数中放置一个警报，该警报应告诉您是否被两次调用.

I don''t see any problem with your code, it could be that this function is somehow called twice in succession. Put an alert in your function and that should tell you if it is called twice.
