Hi I have been playing around with this for a while but no solution yet.

There are three parts to my code, the aim is to create a custom word to insert into a call for a url, so a specific kml file is loaded onto my webmap.

  1. A function to generate a word by clicking a button on my website.(there are 6 other buttons that once clicked create a word)

    var pub = [];
function myFunction7() { 
pub.push("pub");

  2. Once the words have been created, this step adds the variable to an array. The array will = the words needed to match the url. 

    var url = [pub]

    So var url = bar if pub button is clicked.

  3. I would like a new variable to = the words in the array that is generated after the user clicks the buttons. 

    var name = url
var src = "https://www.dropbox.com/"+name+".kml?dl=1";

The problem comes at step 3. Instead of loading the kml the map disappears and url to the kml file is not read so nothing is loaded. Buttons all work, I have tested up to step 2 by printing the result on the web page.

Thanks for any help!

  • it is a map layer but it would be treated the same as any other file you would like to load onto a website Commented Apr 16, 2016 at 13:22

    Well if you cast array to string (which you are doing) you will get comma-separated values. Maby try to var name = url.join(''); If you get the desired src the problem must be somewhere else. Commented Apr 16, 2016 at 13:26
  • And the problem would come from the url that is malformed? Have you set name to "cafebar" before? Commented Apr 16, 2016 at 13:29
  • I have another piece of code to remove the commas. It seems that if I have var name = "bar" the layer loads Commented Apr 16, 2016 at 13:30

    @Kar98k you asked this same question not even an hour ago, so I've flagged this as a duplicate. Commented Apr 16, 2016 at 15:31

Did you check your vars and their typeof? eg. using console.log

I think that, because pub is an array, then url is an array, then name is an array, then your src fails... expecting a string.

If you push only 1 string to pub then you could do:

var url = pub.toString();

or get the first element from pub:

var url = pub[0];

Of course you could do that later on, depending on the rest of your code, eg.

var name = url.toString();
var src = "https://www.dropbox.com/"+name.toString()+".kml?dl=1";

Thank you! This works in creating the correct url (as shown by the console log) but the file is still not loaded automatically onto the map. What does the 0 do in the var url = pub[0]?
it gets the first element from pub array... which is the string "pub" you pushed into it
how did you use the src string?
Is there a way to make the map reload its self after the button has been clicked? I think after the url is updated the map is not initialised with the new url
show code that sets the source attribute to the element... or show a demo of your page
