You can use regular expression capturing groups and exec() function from JavaScript RegExp prototype.

For example, following code will extract everything after the first occurrence of src= or return null if provided string doesn't match.

function extract(str) {
  var regex = /^(?:.*src=)(.*)$/i;
  return regex.test(str) ? /^(?:.*src=)(.*)$/i.exec(str)[1] : null;

document.getElementById('demo').innerHTML = extract('http://localhost/test/test.html?');

Check the explanation of this regular expression and test on different strings at
