母版页如何使用javascript？
母版页invoice_master：
<asp:Content ID= "Content1 " ContentPlaceHolderID= "ContentPlaceHolder1 " Runat= "Server ">
<script language = "javascript ">
function GetTotal()
{
docoment.all[ "tbxTotal "].value = docoment.all[ "tbxSubTotal1 "].value;
}
</script>

<div style= "height:40px; ">
<asp:textbox runat= "server " id= "tbxSubTotal1 " onTextChanged= "GetTotal "> </asp:textbox> </div>
<div> <asp:textbox runat= "server " id= "tbxTotal " > </asp:textbox> </div>

</asp:content>

编译出错：
“GetTotal”不是“ASP.masterpages_invoice_master”的成员。


[解决办法]
在page_load：
tbxSubTotal1.Attributes.Add( "onTextChanged ", "GetTotal() ");
