jQuery Extension for Parsing URL Variables
This is an extension that I have been using to parse URL search strings and hash codes. I thought that I would share it with the world, and if the world has a better method I hope that someone shares it with me.

jQuery.extend({
// return an associative array with url query parameters
urlVars: function() {
// we have a search string
if (window.location.search){
// drop the ? and then split on &
var ary=window.location.search.substr(1).split("&");
var qStr=[];
// for each set
for (i=
0;i<ary.length;i++) {
// split on = and put that array back in original
ary[i]=ary[i].split("=");
// unescape the first item and restore spaces
ary[i][0]=unescape(ary[i][0].replace(/\+/g," "));
// if there is a second item
if (ary[i][1]) {
// unescape the second item and restore spaces
ary[i][1]=unescape(ary[i][1].replace(/\+/g," "));
// we have a pair to return
qStr[ary[i][0]]=ary[i][1];
}
}
// return the pairs
return qStr;
// no search string
} else {
// return an empty array
return [];
}
},
// return a string value for a query parameter
urlVar: function(vnam) {
var vval=$.urlVars()[vnam];
if(vval != undefined) {
return vval;
} else {
return "";
}
},
// return a string value of the first hash
urlHash: function() {
if(window.location.hash){
var ary=window.location.hash.substr(1).split("#");
return ary[0];
} else {
return "";
}
},
// return an array with all the hashes
urlHashes: function() {
if(window.location.hash){
return ary=window.location.hash.substr(1).split("#");
} else {
return [];
}
},
// return true if the hash is present
hasHash: function(hnam) {
if(jQuery.inArray(hnam, $.urlHashes()) > -1) {
return true;
} else {
return false;
}
}
});
