js. Variable inside href?

Question

JavaScript

Is it possible to somehow put a variable inside href?

var urlGo=http://goo.gl;
var googleLink = window.document.querySelectorAll("a[href^='urlGo']");

Answer 1

var link = document.querySelectorAll('a[href]');
for ($i = 0; link.length > i; i++) {
 link[i].setAttribute('href', 'http://goo.gl');
}

Answer 2

Pure JS - only in the script, not in the template (see Viktor's and ErgonomicCode's answers).
If a lot of such good is planned, I would look towards template engines

Answer 3

First you need to fix the errors in the code)))
And only then ...

var urlGo="http://goo.gl"; // строки надо в кавычки брать
// можно так
var googleLink = window.document.querySelectorAll("a[href^="+urlGo+"]");

// или вот так
var selector = [
    "a[href^=", 
    urlGo, 
    "]"
].join('');
var googleLink = window.document.querySelectorAll(selector);
