[OpenLayers-Users] OpenLayers.Layers.Text with variable filename as input

[Robert Sanson]

Hi Carl
 
Indeed it is possible. I do the same with my application. See code snippet below:
 
if(gTF==1){ 
                    var gate = new OpenLayers.Layer.Text( "Gate", {location: "./farmfiles/" + farmid + ".gate"} );
                    map.addLayer(gate);
}
 
In this case, I use a variable called farmid, and the text file is composed of this plus some other bits.
 
Kind regards,
 
Robert Sanson

Hello,

I am very new to OpenLayers and just as new to javascript, so I 
apologize in advance for my lack of basic understanding of all of this.

But, I am attempting to plot points on a map using 
OpenLayers.Layers.Text and it works just fine. However I would ideally 
like to pass the filename in through the URL. In the following line, I 
would like to replace "./lsrtext.txt" with a variable but am having no 
luck.

var newl = new OpenLayers.Layer.Text( "text", {location: "./lsrtext.txt"} );

Is it possible to do such a thing? I have the code working which 
processes the variable name, and I am able to process the lat, lon and 
zoom level this way. But I can't seem to get it working with the 
filename. The documentation states that the URL of the text file can't 
be changed once passed in. Does this count as changing?

Thanks for any help!

-Carl
