动态添加脚本问题
在 <form> 之后添加OK，在 </form> 之前添加就不OK了，请问哪错了？
//.aspx file

{
//MSDN：Page.RegisterClientScriptBlock 方法已被否决。请改用 ClientScriptManager 类的 RegisterClientScriptBlock 方法。
ClientScriptManager csm = Page.ClientScript;
string strScript1 = "script1 ";
string strScript2 = "script2 ";
//OK
if ((!Page.IsPostBack) && (!csm.IsClientScriptBlockRegistered(strScript1)))
{
string ss1 = "alert( '在 <form> 标记之后 ') ";
csm.RegisterClientScriptBlock(this.GetType(), strScript1, ss1, true);
}
//Error
if ((!Page.IsPostBack) && (!csm.IsStartupScriptRegistered(strScript2)))
{
string ss2 = " <script type=\ "text/javascript\ "> function Click(){ alert( '在标记之前 '); } </script> ";
csm.RegisterStartupScript(this.GetType(), strScript2, ss2, true);
}
}
}
[解决办法]
js函数最好放在 <head> </head> 标签内。
在 <body> </body> 标签内进行调用。
