进度参考代码

1.按钮点击的时候开始监视进度
var interval = window.setInterval(GlobalControlProcess, 1500);
2.js调用一般处理程序轮询进度
function GlobalControlProcess(){
$.post("/Common/ComputeProcess.ashx", {ComputeType:"rsk_pro"},function(data){
data=JSON.parse(data);
if (data.state.toString() == "7") {
SetCompleted();
window.clearInterval(interval);
}
else{
SetPorgressBar(Math.ceil(parseInt(data.state)/7*100));
$("#p"+data.state.toString()).fadeIn("slow");
}
});

3.进度完成后清除计时器
window.clearInterval(interval);

4.一般处理程序代码

context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
if (context.Request["ComputeType"]!=null&&!string.IsNullOrEmpty(context.Request["ComputeType"]))
{
string computeType = context.Request["ComputeType"];
if (HttpContext.Current.Session[computeType] == null)
{
HttpContext.Current.Session.Add(computeType,1);
}
var obj = new {state = HttpContext.Current.Session[computeType.ToString()]};
context.Response.Write(Newtonsoft.Json.JsonConvert.SerializeObject(obj));
context.Response.End();

}
