I have a array of numbers like [ "1", "2", "3" ]

and i need to create a url like

https://api.edmunds.com/v1/api/configurator/withOptions?zip=90045&styleid=200701689&deselected=1&deselected=2&deselected=3&fmt=json&api_key=xxxxxxxxxx

You can try something like

var array = [ "1", "2", "3" ];
var params = array.length ? '&selected=' + array.join('&selected=') : '';
result.innerHTML =  params

<div id="result"></div>

Using Array.map()

var array = [ "1", "2", "3" ];
var params = array.map(function(value){
  return '&deselected='+value
}).join('');
result.innerHTML =  params

<div id="result"></div>

I assume they are using PHP or the like, so doesn't it need to be: &selected[]=? – Thomas Sep 23 '14 at 05:28
Hey arun if you dont mind. Can you explain what this line mean var params = array.length ? '&selected=' + array.join('&selected=') : ''; – divakar Sep 23 '14 at 05:29
@divakar What's there to explain? It's a ternary operation. – emerson.marini Sep 23 '14 at 05:30
@divakar if the array does not contain any elements then we want an empty string – Arun P Johny Sep 23 '14 at 05:31

This should also work.

    var url = "https://api.edmunds.com/v1/api/configurator/withOptions?zip=90045&styleid=200701689", array = ["1", "2", "3"];

if (array.length) {
    var separator = "&deselected=";
    var queryParams = separator + array.join(separator);
    url = url + queryParams;
}

array join and create a url
