前台js调用后台代码方法,此方法只适用于后台方法的修饰符为public或protected,如果是其他修饰符会报错。
>后台C#代码:
1 protected int Add(int x, int y) 2 { 3 return x + y; 4 }
>前台JS代码:
1 <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default7.aspx.cs" Inherits="Default7" %> 2 3 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 4 <html xmlns="http://www.w3.org/1999/xhtml"> 5 <head runat="server"> 6 <title></title> 7 <script type="text/javascript"> 8 function m() { 9 var x = "<%=Add(6,4) %>"; 10 alert(x); 11 } 12 </script> 13 </head> 14 <body> 15 <form id="form1" runat="server"> 16 <div> 17 <a href="javascript:void(0);" onclick="m()">JS调用C#代码</a> 18 </div> 19 </form> 20 </body> 21 </html>
C#代码调用javascript
>后台C#代码
1 protected void btnSubmit_Click(object sender, EventArgs e) 2 { 3 Page.ClientScript.RegisterClientScriptBlock(ClientScript.GetType(), "m", "<script>m(); </script>"); 4 }
>前台JS代码:
1 <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default7.aspx.cs" Inherits="Default7" %> 2 3 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 4 <html xmlns="http://www.w3.org/1999/xhtml"> 5 <head runat="server"> 6 <title></title> 7 <script type="text/javascript"> 8 function m() { 9 alert("火云邪神超神!"); 10 } 11 </script> 12 </head> 13 <body> 14 <form id="form1" runat="server"> 15 <div> 16 <asp:Button ID="btnSubmit" runat="server" Text="C#调用JS" OnClick="btnSubmit_Click" /> 17 </div> 18 </form> 19 </body> 20 </html>
结语
说句实话,在.net方面真是个菜,貌似这种调用有三四种方法,可是我就会这种,学的多额。大神看见不要笑哦,IT小菜鸟成长ing
