在C#中编程添加前台脚本

在Page_load函数添加以下代码

private void Page_Load(object sender, System.EventArgs e)
{
file://以下定义需要的客户端脚本，**注意格式**

string script = "< script language=javascript >"+
"function select_unit(element)"+
"{"+
" var arr = window.open(''../Components/UnitListBox.aspx?element=''+element,'''', ''left=200,width=300,top=200,height=230,status=no,toolbar=no,menubar=no,location=no,scrollbars=no'');"+
"}"+
"function select_date(element)"+
"{"+
" var arr = window.open(''../Components/SelectDate.aspx?element=''+element, '''', ''left=200,width=300,top=200,height=230,status=no,toolbar=no,menubar=no,location=no,scrollbars=no'');"+
"}"+
"function show_help()"+
"{"+
" var arr = window.open(''../help/WebPrintHelp.aspx'', '''', ''left=100,width=600,top=100,height=300,status=no,toolbar=no,menubar=no,location=no,scrollbars=yes'');"+
"}"+
"< /script >";
if(!Page.IsClientScriptBlockRegistered("clientScript")) file://这里是关键，判断是否已有ClientScript
this.RegisterClientScriptBlock("clientScript",script); file://这里是关键，如果没有则写上他script
file://试试是否成功
this.ImageButton1.Attributes.Add("onclick","javascript:select_unit(''UserDetail.txtUnit'')");
this.ImageButton2.Attributes.Add("onclick","javascript:show_help()");

file://......其他的功能写在这里
