doing substring in [removed].hash

Question

Somehow window.location.hash is being handled differently in different browsers. If I have a url as follows

http://maps-demo.bytecraft.com.my/postdemo/parcel         


        

Answer 1

You could just use window.location.href instead of hash but why not use regex? More reliable and future-safe than a method based on substringing from character N. Try:

window.location.href.match(/#parcel\/history\/(.*?)(\?|$)/)[1]

Regex isn't the right answer all the time, but sometimes it's just right.

Edit: cleaned up method encapsulation

function GetValue()
{
    var m = window.location.href.match(/#parcel\/history\/(.*?)(\?|$)/);
    return m ? m[1] : null;
}

Answer 2

Try this:

var match = window.location.href.match(/^[^#]+#([^?]*)\??(.*)/);
var hashPath = match[1];
var hashQuery = match[2];

This matches the following parts of the hash:

…#parcel/history/1?as=json&desc[]=ctime&desc[]=history_id
  \______________/ \____________________________________/
   hashPath         hashQuery

Answer 3

You could also do that :

var whatYouWant = window.location.hash.split('?')[0].substring(14);

Answer 4

This is my current solution to the problem

    var get_hash_end = function(_hash) {
        var result = _hash.length;

        if(_hash.search(/\?/g) != -1) {
            result = _hash.search(/\?/g);
        }

        return result;
    };
