Extract Number Between Slashes

This is my setup: var test = 'http://tv.website.com/video/8086844/randomstring/'.match(/^.+tv.website.com\/video\/(.*\d)/); I want to extract the video id(8086844) and the regex

Solution 1:

Try this regex

/^.+tv.website.com\/video\/([\d]+)/

It will search every digit character after ...video\ word and then give all the concordant digits thereafter till any non-digit character comes

Solution 2:

The problem is the (.*\d) part, it looks for a greedy string ends with a digit, instead you need a continues series of digits after video/, it can be done via (\d+)

change it to

var test  = "http://tv.website.com/video/8086844/randomstring/dd".match(/^.+tv.website.com\/video\/(\d+)/)[1];

Solution 3:

var test = "http://tv.website.com/video/8086844/randomstring/8";
test = test.match(/^.+tv.website.com\/video\/(\d+)/);
console.log(test);
console.log(test[1]);

Output

[ 'http://tv.website.com/video/8086844',
  '8086844',
  index: 0,
  input: 'http://tv.website.com/video/8086844/randomstring/8' ]
8086844

You are almost there. We know that, its going to be only numbers. So instead of .*\d we are gathering only the digits and grouping them using parens.

Solution 4:

This is the simplest of all:

Use substr here

test.substr(28,7)

Fiddle

To extract out the id from your string test:We use substr(from,to)
