Question

I have one string

var str = '';
str += 'category='+jv('category')+'&';

str += 'refresh_rate='+jv('refreshRate')+'&';

str += 'submit=Y';

now I want to take values from jv(‘category’) and jv(‘refreshRate’) in separate string in javascript (I want to extract values after “=” and before “&”).

Thanks.

I’ve used this: http://blog.stevenlevithan.com/archives/parseuri
URI Parser in the past and find it simple to use and it doesn’t rely on any other libraries. Its also pretty lightweight.

The author has a demo page but doesn’t really explain how to use it..
Its really simple, you just do something like this:

var url = "http://my-site.com:8081/index.html?query=go&page=2";
var parsed = parseUri(url);

From there you can get things like the host/protocol/port/etc..
When dealing with the querystring you do

var page = parsed.queryKey.page;
alert(page); //alerts 2

Click the parse button on the demo page to see all properties of the parsed URI object that you can access..
