页面js代码：
<script src="js/jquery-1.7.1.js" type="text/javascript"></script>
<script type="text/javascript">
var timer;
function progressShow()
{
//$("#progressSpan").text("<%=progressInt %>%");
$.ajax({
//url: "自写progressBar.aspx/returnProgress",
//type: "text/plain",
//contentType: "application/text;charset=utf-8",
url: "ashx/returnProgress.ashx",
success: function(data){
alert(data);
$("#progressDiv").width(data);
$("#progressSpan").text(data);
},
error: function(error){
alert("error: "+error);
}
});
}
window.onload = function(){ timer = setInterval(progressShow,1500);}
</script>
body：
<div id="contentDiv" style="width:100px; background-color:Gray;">
<div id="progressDiv" style="width:1px; background-color:Red;">
<span id="progressSpan" style="color:Black;"></span>
</div>
</div>
aspx.cs:
namespace progressBar进度条
{
public partial class 自写progressBar : System.Web.UI.Page
{
public static int progressInt;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Thread thread = new Thread(new ThreadStart(progressUp));
thread.Start();
}
}
public void progressUp()
{
for (int i = 1; i < 101; i++)
{
Thread.Sleep(2000);
progressInt = i;
}
}
[WebMethod]
public static string returnProgress()
{
//HttpContext.Current.Response.Write(progressInt);
//HttpContext.Current.Response.End();
return progressInt.ToString();
}
}
}
ashx:
[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class returnProgress : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
context.Response.Write(自写progressBar.progressInt);
}
public bool IsReusable
{
get
{
return false;
}
}
}
实际上progressInt一直在增加，可是为什么取出来的progressInt全是0？
