javascript - read the GET variables in url JQuery

Question

Sorry for another "simple" question, but is there an easy way to read the GET variables from a URL. example. I have a url http://www.domain.com/page.php?var1=1 In my case I will only have 1 variable i.e. var1 or var2 (the variable can change but there will only every be one per url). All the tuts I have seen relate to arrays rather than "singletons" OK I know an array solution may be better but this is just a simple single get variable. Any suggestions? Thanks in advance

Answer 1

var split = location.search.replace('?', '').split('=')

split[0] is your var name, and split[1] is your var value. You actually don't really need jQuery for that piece of code ;)

As for twiz's comment, splitting multiple variables can be done like that:

var split = location.search.replace('?', '').split('&').map(function(val){
  return val.split('=');
});

You can access variable name by split[index][0] and value by split[index][1].

Of course you can use the second snippet instead of the first one for one variable too.
