How to make a url params from array data?

Question

Let's say I can get some data like below:

data = ["s=abc","t=123","a=567","b=789"]

How I can handle these data to obtain a url string like "?s=abc&t=123&a=567&b=789"

I write some code

for(i=0;i<data.length;i++){
  data[i].split("=");
}

but stuck for a while.

Can anyone help me? by the way, the data.length may different each time.

Thanks.

Use join with & as glue. This will concat the elements of the array by using & as glue, then you can prepend ? to the resulting string.

var data = ["s=abc", "t=123", "a=567", "b=789"];
var params = '?' + data.join('&');

console.log(params);
document.write(params);

Note: If your parameters contains special characters you can use encodeURIComponent to encode it.

If you need the params to be url encoded, use $.param( data);
