Problem:
How can we check for a #hash in a URL using javascript ?
Solution 1:
URL properties in document.location. Same URL properties are also available to anchor elements:
// To process anchors on click
jQuery('a').click(function () {
if (this.hash) {
// Clicked anchor has a hash
} else {
// Clicked anchor does not have a hash
}
});
// To process anchors without waiting for an event
jQuery('a').each(function () {
if (this.hash) {
// Current anchor has a hash
} else {
// Current anchor does not have a hash
}
});Solution 2:
You can use this:
if(window.location.hash) {
// Fragment exists
} else {
// Fragment doesn't exist

Try this:
if(window.location.hash) {
var hash = window.location.hash.substring(1); //Puts hash in variable, and removes the # character
alert (hash);
// hash found
} else {
// No hash found
}Solution 4:
This is one of the solution:
<script type="text/javascript">
if (location.href.indexOf("#") != -1) {
// Our code in here accessing the string like this
// location.href.substr(location.href.indexOf("#"))
}
</script>

If the URL is not in the document's location this code will be responsible.

alert(hash)
} else {
// do something else
}Solution 6:
This code helps to solve the problem.
$('#myanchor').click(function(){
window.location.hash = "myanchor"; //set hash
return false; //disables browser anchor jump behavior
});
$(window).bind('hashchange', function () { //detect hash change
var hash = window.location.hash.slice(1); //hash to string (= "myanchor")
//do sth here, hell yeah!
});
