如何在一个功能EXCUTE多个ClientScript.RegisterStartupScript（）？ [英] how to Excute more than one ClientScript.RegisterStartupScript() in one function?

问题描述

我要执行从服务器端JavaScript函数，所以我说下面一行：

I want to execute javascript function from server side, so i added following line:

 ClientScript.RegisterStartupScript(Page.GetType(), "@msg", "ValidateRequiredFields('" + txtRequiredFieldValidation.ClientID + "');", true);

它工作正常。但我想上面的语句之后立即执行相同的JavaScript函数。
所以我加了以下几行：

it works fine. but i want to execute same JavaScript function immediately after above statement. so i added following lines :

ClientScript.RegisterStartupScript(Page.GetType(), "@msg", "ValidateRequiredFields('" + txtEmailValidation.ClientID + "');", true);
        ClientScript.RegisterStartupScript(Page.GetType(), "@msg", "ValidateRequiredFields('" + txtOnlyNumbersValidations.ClientID + "');", true);

但我注意到，只有第一个startupscript执行。为什么？我怎么能在一个函数执行多个startupscript？

but i noticed that only first one startupscript executes.. why? how can i execute multiple startupscript in one function?

推荐答案

根据 MSDN

用的RegisterStartupScript方法添加的脚本块在页面加载完毕，但页面的onload事件引发之前执行。脚本块不保证>是在他们注册的顺序输出。如果脚本块的顺序是>重要的是，使用StringBuilder对象在一个字符串来收集脚本在一起，>然后注册他们都在一个单一的客户端脚本块。

The script block added by the RegisterStartupScript method executes when the page finishes loading but before the page's OnLoad event is raised. The script blocks are not guaranteed >to be output in the order they are registered. If the order of the script blocks is >important, use a StringBuilder object to gather the scripts together in a single string, and >then register them all in a single client script block.

所以，把共同呼吁应为你工作。

So putting the call together should work for you

"ValidateRequiredFields('" + txtEmailValidation.ClientID + "');
 ValidateRequiredFields('" + txtOnlyNumbersValidations.ClientID + "');"
