显示FileUpLoad控件所浏览的图片?
今天编程的时候我想用
this.Image1.ImageUrl =FileUpload1.PostedFile.FileName;
显示FileUpLoad控件所浏览的图片,可是显示不出来.
在网上查了之后,发现了这样一段代码:
"源"代码:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="CarSignStory.aspx.cs" Inherits="后台管理_CarSignStory" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>无标题页</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:FileUpload ID="FileUpload1" runat="server" />
<img id="img" style="display:none"/>
</div>
</form>
</body>
</html>.cs文件代码:
protected void Page_Load(object sender, EventArgs e)
{
FileUpload1.Attributes.Add("onchange", "document.getElementById('img').src=this.value;document.getElementById('img').style.display='block';"); 
}
