Hi guys,

Forgive me if this is a stupid question as I'm fairly new to computing. Been trying to make a webpage that displays a googlemap with multiple markers based on data from an XML file but can't seem to get it to work. Would be ETERNALLY grateful to anyone who can pick out where I'm going wrong!

<html>
<head>
<script type="text/javascript">

	function callXML(){
		if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
  			xmlhttp=new XMLHttpRequest();
  		}
		else {// code for IE6, IE5
  			xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  		}
		xmlhttp.open("GET","partners.xml",false);
		xmlhttp.send();
		return xmlhttp.responseXML;
	}
	
		xmlDoc=callXML();
		
		var partners=xmlDoc.getElementsByTagName("partner");
		var lats=new Array();
		var lngs=new Array();
		var titles=new Array();
		var descs=new Array();
		var lat;
		var lng;
		var title;
		var desc;

		for (var i=0;i<partners.length;i++) {
				lat=partners[i].getAttribute("lat");
				lats.push(lat);
				lng=partners[i].getAttribute("lng");
				lngs.push(lng);
				titles=partners[i].getAttribute("title");
				titles.push(title);
				descs=partners[i].getAttribute("desc");
				descs.push(desc);
		}
		
		var latlng = new google.maps.LatLng(lats[0], lngs[0]);
		var myOptions = {zoom: 11, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP};
    	        var map = new google.maps.Map(document.getElementById("map_canvas"),myOptions);
		
		for (i=0;i<partners.length;i++){
				latlng = new google.maps.LatLng(lats[i], lngs[i]);
				marker= new google.maps.Marker({position: latlng, map: map, title: titles[i]});
		}

Rinjin,

Here's a few things to try:

Give the page a doctype (first line, right at the top of the file). eg.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Install google maps on the page:
<script src="http://maps.google.com/maps/api/js?sensor=false" type="text/javascript"></script>

If it still doesn't work, then split the code down the middle and test the two halves separately :

  1. 2nd half: Work with hard-coded arrays - lats, lngs, titles and descs - for say 3 or 4 points. Do the markers appear on the map?
  2. 1st half: Fetch the xml file and populate the arrays. Do the arrays contain the correct data as expected?

When both halves work, then put them back together. It will work.

Hi Airshow,

Thanks so much for taking the time to try and help me. I've added in the bits you suggested and I have tried to test it in that way but it seems like no matter what I do the page won't even display the map, with or without the markers, it's always just a blank page :<

Member Avatar for Airshow

If your test with hard-coded arrays yields a blank page then then you need to concentrate on the Google code. Make sure that the AJAX code is commented out.

Do you get an error in your error console or does it fail silently?

Have you tried testing with hard-coded values in the line var latlng = new google.maps.LatLng(lats[0], lngs[0]); ?

Hi Airshow,

Thanks for bearing with me. I did try that but I still get the same problem of having nothing displayed, but not sure where to go from there :<<

I did notice that I didn't declare the marker variable though, so have added that in at least

Member Avatar for Airshow

Rinjin,

I've not tried running your code but guess it will fail at line 42 (maybe silently), because the DOM element with id="map_canvas" doesn't exist when the code runs.

By wrapping all your javascript in:

onload = function(){
    //your code here
}

you will ensure that it doesn't run until the HTML in the document body has been interpreted and rendered.

You also need to give the canvas some width and height.

Add to the document head:

<style>
#map_canvas {
	width:300px;
	height:300px;
	border:1px solid #000;
}
</style>

I've changed some stuff around and have gotten the map to show, but none of the markers are coming up even if i hardcode the lat and lng. code looks like this atm

Rinjin, you're still trying to debug the whole thing in one go.

First get the markers right with hard-coded data, then debug the AJAX.

The line for (i=0;i<title.length;i++){ needs fixing. It should loop through the array titles not the string title .

That's not what I meant by hard-coded. The code still relies on partners and partners relies on AJAX to deliver an xml file.

Also, now there's a mixture of google maps api v2 and v3. Should be v3 throughout.

This is more like what I was expecting to see:

okay thank you, so i guess that means there's a problem with my arrays? ive replaced the hard code with the section of my code that is meant to fetch the attributes and push them into the prospective arrays but it's gone right back to the problem of displaying nothing

Member Avatar for Airshow

Yes, that's what I would expect. The problem is not with the arrays themselves but with the way you are trying to populate them with data.

You need to do some background reading on AJAX.

Hint: xmlhttp.open("GET","partners.xml",false); won't work in most browsers. Try xmlhttp.open("GET","partners.xml",true); with an asynchronous response handler.

With the help of examples on the web, you'll find it's quite simple. I could write the for you but you will get more satisfaction from doing it youself.

Yeah I appreciate that, thank you, and I know it's a lot more work for you to try and drop hints rather than come out with the answer. but it hasnt worked at all, would it help if i provided the xml code as well?

Don't get despondent. I've learned this stuff over the last 13 years or so and some of it was hard work.

Hello rinjin07
you are using AJAX call in sync context.
The "A" in AJAX stands for "Asynchronous"

Therefore this code might get you walking:

var oReq = getXMLHttpRequest();
var xmlDoc;

function getXMLHttpRequest(){
        return new window.XMLHttpRequest;
	}

function handleRequest(){
	    if( oReq.readyState == 4 ){
	        if( oReq.status == 200 ){
	xmlDoc = oReq.responseXML;
	procesXMLData() 
		}
	    }
	}
	
if (oReq != null) {
	    oReq.open("GET", "partners.xml", true);
	    oReq.onreadystatechange = handleRequest;
	    oReq.send();
}
	
function procesXMLData(){
	var lat, lng, title, desc;
	var lats=[], lngs=[], titles=[], descs=[];
	var partners=xmlDoc.getElementsByTagName("partner");

alert(partners[0])	/*if you get this alert you are good to go
		if alert 'undefined' or something bad:
		change "partners.xml" to its absolute url
		else remove this alert and continue debugging hereon
		if the rest of the script is good but still no go
		re-check your html code as adviced by Airshow */

	for (var i=0;i<partners.length;i++) {
		lat=partners[i].getAttribute("lat");
		lats.push(lat);
		lng=partners[i].getAttribute("lng");
		lngs.push(lng);
		titles=partners[i].getAttribute("title");
		titles.push(title);
		descs=partners[i].getAttribute("desc");
		descs.push(desc);
	}
	
	var latlng = new google.maps.LatLng(lats[0], lngs[0]);
	var myOptions = {zoom: 11, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP};
    	        var map = new google.maps.Map(document.getElementById("map_canvas"),myOptions);
	
	for (i=0;i<partners.length;i++){
			latlng = new google.maps.LatLng(lats[i], lngs[i]);
			marker= new google.maps.Marker({position: latlng, map: map, title: titles[i]});
	}

Hello

You need to debug this step first:

var oReq = getXMLHttpRequest();
var xmlDoc;

function getXMLHttpRequest(){
        return new window.XMLHttpRequest;
	}

function handleRequest(){
	    if( oReq.readyState == 4 ){
	        if( oReq.status == 200 ){
	xmlDoc = oReq.responseXML;
	procesXMLData() 
		}
	    }
	}
	
if (oReq != null) {
	    oReq.open("GET", "partners.xml", true);
	    oReq.onreadystatechange = handleRequest;
	    oReq.send();
}
	
function procesXMLData(){
	var lat, lng, title, desc;
	var lats=[], lngs=[], titles=[], descs=[];
	var partners=xmlDoc.getElementsByTagName("partner");

	alert(partners[0])	
	}

Because If you've only pasted the previous code without inspecting your following declarations - you'd undoubtedly fail. Because the function {procesXMLData} is left open [not finished] for you to work on. If nothing else, it lacks its final closing "}" and will fail to register / cause a javascript error before anything else. As it did.

OK than, first:
Watch if(this shortened code) will give you an alert box, -If it does:

A) But theres nothing useful in its message content (as I sugested earlier) - format your xml doc reference as absolute i.e.: "http://mydomain.com/mycordsfolder/partners.xml" and refresh you page.
If this doesn't solve the problem: please make sure that your "partners.xml" file: 1. Exists; 2. Is in the same folder; 3. Contains Tags of type <partner> (in same case xml sensitive nature).

Just drop the filthy XML completely, that was never meant to be and wasn't even supposed to exist. It's a worthless artificial w3c crap that was never meant to be used in practice anyway.


Here, try this:

Name it "partners.txt"; save it in UTF-8 in any case to avoid server complications do the same with html, it is set as utf anyway.

And no don't use the bloody UTF it doesn't support all characters (used) - leave it as is, let the browser detect encoding, it does a better job than me. This revision uses markers also...

Have fun

Meanwhile, I have something completely different in mind but I won't post it because Troy's approach will certainly do the job if departure from (evil) XML is ok.

Member Avatar for Troy III

Well... :')
-There's no such thing as evil Language i.e.,[any communications protocol], the thing with xml and other web filth, is that they are practically unusable.
xhml is dead, thank goodness - long live HTML.

But anyway feel free to post it, I like your coding manner.

p.s: have you tried the last revision? Only tested on IE9 and Fx5 but I'm sure it will work full range, way back to IE4.01.

Regards.

the xml i sent is only exemplary, have over 30 instances of partners i need to add in :<

Member Avatar for Troy III

well that's what you get for using xml.
converting it all into a js-DSO [javascript data source objrct] on some rich text editor is a breeze.

You take a sample of mine compare it with your xml: find the diferences an use find / replace than copy-paste it all in a plain text document . And yes nowdays its called a JSON.

You could use some XML to JSON converter but youre out of luck -your xml is mallformed according to dreaconian error handling of you data formulation on the xml parser I gues.

-but here are two possible automatic conversions made online:

Troy,

p.s: have you tried the last revision? Only tested on IE9 and Fx5 but I'm sure it will work full range, way back to IE4.01.

Both versions work fine here in Opera 11.50 under Win7.

Your code is so concise, I'm almost afraid to post my monster, though it does contain a little extra functionality (clickable markers and an infoWindow) and you can switch between external and hard-coded data for dev/testing.

I won't post it yet because it will give Rinjin a headache from too many choices.
