How can i get value with javascript regular expressions

i have following text

http://www.mydomain.com/#!/account/?id=17

and i am getting # with window.location.href which is gi开发者_开发百科ving me

#!/account/?id=17

now i want to extract that id value with preg_match or any regular expression because that id value is dynamic... actually i am loading data with jquery ajax...please let me know the exact expression for getting value of id...

Try this:

"#!/account/?id=17".match(/id=(.*)/)[1]

EDIT

var result = window.location.href.match(/id=(.*)/);

• match returns an array with two positions:
  • result[0] = all matched string ("id=17")
  • result[1] = first group match ("17")
