从后面的代码中调用javascript函数 [英] Calling javascript function from code behind

问题描述

我有一个帐户设置页面，用户可以在其中更改公司名称，管理员密码或主密码.我正在使用javascript和链接.当用户单击更改管理员密码"链接时，将调用javascript代码，并将相应的"div"设置为style.display = inline(否则，其始终为style.display = none).设置密码后，用户单击保存密码"(一个按钮).这导致回发，因此可见的"div"被隐藏.

我正在尝试在page_load上调用一个javascript函数来检查用户是否正在使用管理员密码，它应该显示它，即set style.display = inline ...但是我无法做到这一点.我正在使用的代码被称为一次，但不是在每个回发中.请帮助:

这是我的代码，用于在page_load
上调用javascript函数

 如果(不是 ClientScript.IsStartupScriptRegistered(  viewdiv"))我. GetType ()，"  viewdiv" ;,   view('divAdminPassword'); "，结束 如果 

而我的javascript函数是:

功能视图(obj)
     {
          var  div = document.getElementById(obj);


                div.style.display = " ;

    }

首先从上面的主题的一些背景知识开始阅读CodeProject文章

这真的很奇怪

我在一个aspx文件中有以下代码

 暗链接 As  字符串 = " & ViewState.Item(" )
                           如果(不是 ClientScript.IsStartupScriptRegistered("  OpenPage")))我. GetType ()，"  OpenPage"，  window.open('"& link& " ，真)

                           结束 如果 

它设法使用url
打开一个新窗口
当我尝试在其他页面上使用相同的脚本时，它不起作用！
可能是什么问题?

 page.clientscript.registerscriptblock(我. gettype ()，" ，"  

I have an account settings page where the user can change the company name, admin password or main password. I am using javascript and links. When user click the "change admin password" link, the javascript code is called and the appropriate "div" is set to style.display=inline (otherwise its always style.display=none). After setting the password, the user clicks "Save Password" (a button). This causes a postback and so the visible "div" gets hidden.

I am trying to call a javascript function on page_load to check if the user was working on the admin password, it should display it i.e set style.display=inline... however i am unable to do that. The code i am using just gets called ONCE but not on every postback. Kindly help:

Here is my code for calling the javascript function on page_load

If (Not ClientScript.IsStartupScriptRegistered("viewdiv")) Then

                Page.ClientScript.RegisterStartupScript _
(Me.GetType(), "viewdiv";, "view('divAdminPassword');", True)
            End If

And my javascript function is:

function view(obj)
     {
         var div = document.getElementById(obj);


                div.style.display = "inline";

    }

Start with some background reading on the subject above is a CodeProject Article

this is really strange

i have the following code in one aspx file

Dim link As String = "collection.aspx?SettleID=" & ViewState.Item("SettleID")
                           If (Not ClientScript.IsStartupScriptRegistered("OpenPage")) Then

                               Page.ClientScript.RegisterStartupScript _
                                                   (Me.GetType(), "OpenPage", "window.open('" & link & "');", True)

                           End If

it manages to open a new window with the url

when i try to use the same script on other pages, it does not work!
what could be the issue?

page.clientscript.registerscriptblock(me.gettype(),"alert","alert('Invalid username',true)"
