使用ajax时出现警报脚本问题！！！！ (C#asp.net) [英] Alert script problem when using ajax!!!! (c# asp.net)

问题描述

嗨朋友..
感谢您给予我的答复.

现在我想问一件事，我正在使用服务器端的警报消息框，如您给我的代码一样，如


if(txtusername.text.trim()== string.empty)
{
response.write("alert(``输入用户名'');");
}

在不使用ajax的情况下也可以正常工作，
但是当我使用ajax控件(脚本管理器和更新面板)时，
它不起作用..
Ajax是什么问题?
如果代码中有什么变化，请告诉我..


我也想知道我也可以将警报框用于其他数据格式吗?喜欢验证(日期时间，整数值，电子邮件地址..)

并可以使用IF(condition)来完成它，就像我已经为空文本框做到了吗?

或者，如果您可以告诉我其他服务器端验证方法，请告诉....

非常感谢..::

hi friends..
thanks for your answers given to me..

now i want to ask one more thing that i am using the alert message box in the server side as per your code given to me like


if(txtusername.text.trim()==string.empty)
{
response.write("alert(''Enter username'');");
}

its working fine without using ajax,
but when i use ajax controls (script manager and update panel),
its not working..
what is the problem with ajax??
and if there is something to change in the code, then tell me..


i also want to know can i use alert box for other data formats too?? like to validate (datetime, integer value,email address..)

and can it be done with IF(condition) like i have done it already for the empty textbox??

or if you can tell me other server side validation method then tell....

thanks a lot.. :)

使用AJAX时，必须使用ScriptManager 来执行脚本.试试这个.

While using AJAX, you have to use ScriptManager for executing the script. Try this.

ScriptManager.RegisterStartupScript(this, 
    this.GetType(), 
    "AlertScript", 
    "alert(''Enter username'');", 
    true);
