Question

I have a URL that includes a product ID which can be in the following format:

One alphabetical letter followed by a number of any number of digits, then an underscore, and then any number of digits and underscores.

So this is a valid product id: c23_02398105 and so is this: c23_02398105_9238714.

Of course in a URL, it’s sandwiched between other query string items, so in this url, i want to extract just the id:

http://www.mydomain.com/product.php?action=edit&id=c23_02398105&side=1

I’ve been trying a regex something along the lines of this, to no avail:

/&id=[a-z]_[(0-9)*]&/

What’s the correct way to extract the product id?

Answer 1

function qry(sr) {
  var qa = [];
  for (var prs of sr.split('&')) {
    var pra = prs.split('=');
    qa[pra[0]] = pra[1];
  }
  return qa;
}

var z = qry('http://example.com/product.php?action=edit&id=c23_02398105&side=1');
z.id; // c23_02398105
