1. js中点击按钮将html页面导出成图片
一、添加引用在解决方案上单击右键，选择“Add Reference。”
添加“System.Windows.Forms”，添加完后，Web.Config 中应该有类似下面的内容：二、设置 STA 模式在 @ Page 指令中加上 AspCompat="true"，以强制该网页在 STA（单线程单元） 模式下执行。结果类似如下：<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" AspCompat="true" %>三、写截图代码using System;using System.Collections;using System.Configuration;using System.Data;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.HtmlControls;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Drawing;using System.Drawing.Imaging;using System.Windows.Forms;public partial class _Default : System.Web.UI.Page{private WebBrowser _webBrowser;protected void Page_Load(object sender, EventArgs e){string url = Request.QueryString["url"];if (string.IsNullOrEmpty(url)){url = ">
<head>
<script type="text/javascript">
var count=0;
function Change(){
count++;
if(count>18){
count=1;
}
i = document.getElementById("image");
j = document.getElementById("txt");
j.value="当前照片第"+count+"张"；
if(count<10){
i.src="../../image/00"+count+".jpg";
}else{
i.src="../../image/0"+count+".jpg";
}
}
</script>
</head>
<body onl oad="Change();">
<p>；点击图片，切换到下一张，最后一张的下一张是第一张</p>
<p><input id="txt" type="text" /></p>
<div>
<img id="image" name="image" src="" onclick="Change();" />
</div>
</body>
</html>
