[原创]巧妙的让web来执行“计划任务”

updateIndex.asp:

<scrīpt language="Jscrīpt" runat="server">
var fso = new ActiveXObject("scrīpting.FileSystemObject");
var fts = fso.GetFile(Server.MapPath("index.shtml"));

var s = new Date(fts.DateLastModified).getDate();
fso = null;
var t = new Date().getDate();

if(s == t){
    Response.Write("var typeString = '你找到这里来干嘛？';");
    Response.End();
}
else{
    //省略生成index.shtml的代码
    Response.Write("setTimeout(\"parent.location.reload();\",5000);");
    Response.End();
}
</scrīpt>

在index.shtml页面引用方式：

<scrīpt language="Javascrīpt" src="updateIndex.asp"></scrīpt>
