Scores not updating

[kingmullet]

Is anyone else running into an issue with updating the scores? It’s been working fine then all of the sudden this week it times out while trying to load.

[Smokey Jones]

I had that happen on Thursday as well. I'm hoping that it was a problem with the NFL feed. I just tried it and it's still acting up.

[huhwhut]

I've got the same thing. Scores not updating.

[Lush]

It's still down for me too....bummer

[chuckie365]

Does anybody have any ideas how to fix this problem? Thanks!

[Keno]

Yes, I am on-board with chuckie365 - how can we get this fixed? It's a very useful and fantastic part of the program. Thanks!!

I think the root of the problem might be that NFL.com has changed how they are serving up scores in the https://www.nfl.com/scores/2018/REG page. Unfortunately, I don't know enough about how the data is parsed in the UpdateScores.asp file to figure it out.

[BobbyG63]

This was driving me crazy.
So I coded a Score Loader that is driven from the NFL XML feed.
Lighting fast because it does not have to wait for the NFL Score site to load and then to scrape the score from it.
Let me know what you think.

Replace the "scoresLoader" code in the "UpdateScores.asp" with the code below...

Code: Select all

	//=========================================================================
	// Module: scoresLoader
	//
	// Used to set game scores using data retrieved from the NFL.com web site.
	//=========================================================================
	var scoresLoader = function () {

		// The update form.
		var formEl = null;

		// The week to update.
		var week = "";

		// Define an array to hold form field information for each game listed
		// on the form.
		var gameFields = [];

		// Auto-update parameters.
		var autoUpdate               =  false;
		var autoUpdateLoadTimeoutID  =   null;
		var autoUpdateLoadTimeout    = 300000; // 5 minutes.
		var autoUpdateDialogTimeout  =    500; // one half second.

		// Holds the data parsed from the scores page.
		var gameData = null;

		// Used for dialog messages.
		var resultMsg       = "";
		var errorMsg        = "";
		var foundNewResults = false;

		//---------------------------------------------------------------------
		// Initializes the scores loader.
		//---------------------------------------------------------------------
		function init() {

			// Get the scores update form.
			formEl = document.getElementById("scoresForm");

			// Get the week.
			week = formEl.elements["week"].value;

			// Scan the form and build the games fields array.
			var i = 1;
			var el;
			while ((el = formEl.elements["id-" + i]) != null) {

Following... waiting for a fix

[chuckie365]

Thanks for the fix. For some reason the auto update didn't work with the NE KC game but it worked with the others!

[GiantsFan]

Thanks for the re-write BobbyG63, that worked for me.

[BobbyG63]

After posting my original fix, I noticed that the feed I was using that allows for the selection of Year Season, and Week is not as "real-time" as I expected. The feed that is closer to "real-time" does not allow for the selection of Year, Season, and Week.

I modified the code to pull from the "real-time" feed, check to see if it is the current week and process.
If it is not the current week, I go back to using the historic data feed.

In UpdateScores.asp, in the processXMLScores function:

Replace:

Code: Select all

			var xmlURL = "http://www.nfl.com/ajax/scorestrip?season=2018&seasonType=REG&week="+week;
			var myData = getDataFeed(xmlURL);
			var parser = new DOMParser();
			var xmlDoc = parser.parseFromString(myData, "text/xml");

			var gameEls = xmlDoc.getElementsByTagName("gms");
			if (gameEls.length > 0) {
				var week = gameEls[0].getAttribute("w");
				var year = gameEls[0].getAttribute("y");
				var type = gameEls[0].getAttribute("t");
				if (type == "R")
					week = "REG" + week;
				else
					week = "PRE" + week;
			}

With:

Code: Select all

			var xmlURL = "http://www.nfl.com/liveupdate/scorestrip/ss.xml"
			var myData = getDataFeed(xmlURL);
			var parser = new DOMParser();
			var xmlDoc = parser.parseFromString(myData, "text/xml");

			var gameEls = xmlDoc.getElementsByTagName("gms");
			if (gameEls.length > 0) {
				var week = gameEls[0].getAttribute("w");
				var year = gameEls[0].getAttribute("y");
				var type = gameEls[0].getAttribute("t");
			}			
			
			if (formWeek != week) {
				var xmlURL = "http://www.nfl.com/ajax/scorestrip?season=2018&seasonType=REG&week="+formWeek;
				var myData = getDataFeed(xmlURL);
				var parser = new DOMParser();
				var xmlDoc = parser.parseFromString(myData, "text/xml");
			}

Happy scoring!!!

[mspslb]

Working great for me and load time is very fast. Really appreciate the fix!

[Smokey Jones]

Lighting fast because it does have to wait fro the NFL Score site to load and then to scrape the score from it.
Let me know what you think.

Dude! You weren't kidding when you said "lightning fast"!! This is awesome!!! Thanks for coding this and sharing it with us!

Thanks BobbyG63!! This is AWESOME & wicked fast!

I've tried implementing this and it didn't work. Autoupdate just hangs.

[CDKING1]

I made the changes but not working for me as well.

[mspslb]

Same here when I tried it earlier this week. I think it has to do with the formWeek variable. It isn't declared and no value for it. Haven't had a chance to look further since, but I think that is where the issue lies. I think there are some changes that weren't included in the paste.

[chuckie365]

The original change he suggested is working ok for me...haven't tried the second modification yet...

[baldy51497]

Correct, I believe this fixed the loading. Pretty simple change, but trying to contribute. Bare with me here, first time posting code.

Replace:

Code: Select all

			var week = formEl.elements["week"].value;

With:

Code: Select all

			
			var week;
            		var formWeek = formEl.elements["week"].value;

[BobbyG63]

In the 4.0 version of updateScores, var week = ""; is defined up top, under the scoresLoader function.
and the "week" that is refereed to in the "formEl.elements["week"].value" statement comes from the form
"<div><input type="hidden" name="week" value="<% = week %>" /></div>"

Can someone explain the problem and I will look to see how to correct it?

Thank you...

[baldy51497]

The problem was just that the scores weren't loading. I apologize that my suggested fix may have not been correct, even though it did seem to make it work. I didn't look through the whole document to determine what variables had been initiated. I believe that mspslb was correct though when he stated that the loading problem was caused by the formWeek variable. I definitely don't fully understand programming, but I do understand the basics, so I am just being impatient and trying to help. Question, so is "week" always set by the init function, setting it from the hidden form input value? So does it need to be set again in the scoresloader? And would the better fix be to just change the "week" variable you are setting from the xml to be something like "xmlWeek"? Then checking whether the form week "week" is different from the most current feed week "xmlWeek"? BobbyG63, thanks for your rewrite, it is very fast like you said.

I tried it a few different ways, and they all break it. So my fix isn't really best, but I can't figure out what the correct fix is.

[BobbyG63]

No problems Baldy... It's all good...
To answer your question...
No, week comes from the 1st XML feed (which does not allow for a requested week, the NFL is always returning current week)
So if the Form week differs from the LiveFeed XML, then you have to request the scores with the Ajax call. That calls allows you to specify the requested week.

The code is working perfectly for me... Should I re-post the entire scoresLoader function?

[mspslb]

@BobbyG63 that would be good, if you don't mind.
