I have a function which have a long execution time.
public void updateCampaign()
{
context.Session[processId] = "0|Fetching Lead360 Campaign";
Lead360 objLead360 = new Lead360();
string campaignXML = objLead360.getCampaigns();
string todayDate = DateTime.Now.ToString("dd-MMMM-yyyy");
context.Session[processId] = "1|Creating File for Lead360 Campaign on " + todayDate;
string fileName = HttpContext.Current.Server.MapPath("campaigns") + todayDate + ".xml";
objLead360.createFile(fileName, campaignXML);
context.Session[processId] = "2|Reading The latest Lead360 Campaign";
string file = File.ReadAllText(fileName);
context.Session[processId] = "3|Updating Lead360 Campaign";
string updateStatus = objLead360.updateCampaign(fileName);
string[] statusArr = updateStatus.Split('|');
context.Session[processId] = "99|" + statusArr[0] + " New Inserted , " + statusArr[1] + " Updated , With " + statusArr[2] + " Error , ";
}
So to track the Progress of the function I wrote a another function
public void getProgress()
{
if (context.Session[processId] == null)
{
string json = "{\"error\":true}";
Response.Write(json);
Response.End();
}else{
string[] status = context.Session[processId].ToString().Split('|');
if (status[0] == "99") context.Session.Remove(processId);
string json = "{\"error\":false,\"statuscode\":" + status[0] + ",\"statusmsz\":\"" + status[1] + "\" }";
Response.Write(json);
Response.End();
}
}
To call this by jQuery post request is used
reqUrl = "AjaxPages/lead360Campaign.aspx?processid=" + progressID + "&action=updatecampaign";
$.post(reqUrl);
setTimeout(getProgress, 500);
get getProgress is :
function getProgress() {
reqUrl = "AjaxPages/lead360Campaign.aspx?processid=" + progressID + "&action=getProgress";
$.post(reqUrl, function (response) {
var progress = jQuery.parseJSON(response);
console.log(progress)
if (progress.error) {
$("#fetchedCampaign .waitingMsz").html("Some error occured. Please try again later.");
$("#fetchedCampaign .waitingMsz").css({ "background": "url(common/images/ajax_error.jpg) no-repeat center 6px" });
return;
}
if (progress.statuscode == 99) {
$("#fetchedCampaign .waitingMsz").html("Update Status :"+ progress.statusmsz );
$("#fetchedCampaign .waitingMsz").css({ "background": "url(common/images/ajax_loded.jpg) no-repeat center 6px" });
return;
}
$("#fetchedCampaign .waitingMsz").html("Please Wait... " + progress.statusmsz);
setTimeout(getProgress, 500);
});
}
But the problem is that I can't see the intermediate message. Only the last message is been displayed after a long lime of ajax loading message
Also on the browser console I just see that after a long time first requested is completed and after that the second request is completed. but there should be for getProgress ?
I have checked jquery.doc and it says that $post is an asynchronous request.
Can anyone please explain what is wrong with the code or logic?
