Using jQuery to append URL with anchor #
Question by jeffkee
While retrieving items via AJAX etc., the links are set to do this:
$(this).click(function(){
ajax_function(); // hypothetical ajax call that puts data into a <div> of my choice
return false;
});
In this scenario, I’m wondering what the best way is to utilize jQuery to add things to my URL in this format:
http://www.mydomain.com/products
turns into
http://www.mydamain.com/products#category-12,page-4
Further note- I’m talking about the actual URL of the browser (in the URL bar) not a URL that is part of the DOM.

After searching some more (with better keywords than before on Google) I found the answers I needed, and I wrote the following functions:
function get_url_hash(argument) {
var hash = location.hash.replace('#','');
if(argument=='' || argument==undefined) {
return hash;
alert(blank);
} else {
var foundhash = false;
// specific argument given - let's find the value attached.
var hashblock = hash.split(',');
for(x in hashblock) {
var hasharray = hashblock[x].split('-');
if(hasharray[0]==argument) {
return hasharray[1];
foundhash = true;
}
}
if(foundhash==false) {
return false;
}
}
}
function modify_url_hash(argument, value) {
// This function goes through the entire hash,
// figures out which parts of the hash should be added, updated or removed based on entry,
// and then spits out final result.
var hash = get_url_hash();
var foundhash = false; // foundhash is set to false by default. if this hash is NOT found, then we add it at the end!
var hashcount = 0; // keep count of total # so as to determine where to put the commas etc.
var newhash = '';
if(hash.length>0) {
var hashblock = hash.split(',');
for(x in hashblock) {
var hasharray = hashblock[x].split('-');
if(hasharray[0]==argument) {
hasharray[1] = value;
foundhash = true;
}
if(hasharray[1]!=false && hasharray[1]!='') { // if new value is NOT false, we keep it in.. otherwise don't feed it to newhas so it disappears.
if(hashcount>0) { newhash = newhash+','; }
newhash = newhash+hasharray[0]+'-'+hasharray[1];
hashcount++;
}
}
}
if(foundhash==false) {
// this is a new hash block.
if(hashcount>0) { newhash = newhash+','; }
newhash = newhash+argument+'-'+value;
}
location.hash = newhash;
}

May be something like
oldlink = $('#mylinkselector').attr("href");
newlink = oldlink="#category-12,page-4";
$("#mylinkselector").prop("href",newlink);
