[OpenLayers-Users] Drawing on the fly route

[Matthew Pulis]

Hi,

Just would like to say that finally with the help of crschmidt and pgiraud
from #OpenLayers , I managed to get the routing working.

I would like to say that the tutorial on pgRouting has some old things that
I suggest should be changed to reflect the new OpenLayers.js

function displayRoute(response) {

if (response && response.responseXML) {

// erase the previous results result.removeFeatures(result.features);

// parse the features var edges =
response.responseXML.getElementsByTagName('edge');
var features = []; for (var i = 0; i < edges.length; i++) {

var wkt = edges[i].getElementsByTagName('wkt')[0].textContent; var g =
parser.read(wkt); features.push(g);

} result.addFeatures(features);

}

}

In the function on the wiki, there is features.push(new
OpenLayers.Feature.Vector(g)); which now should just be changed with
features.push(g); since g is already a Feature.Vector array so no need to
mention it again.

Thanks alot for your support, and hope this thread helps others with my
problem :)

Cheers
