Javascript Solutions
Solution 1 - Javascript
var path = window.location.pathname;
var page = path.split("/").pop();
console.log( page );
Solution 2 - Javascript
Current page: It's possible to do even shorter. This single line sound more elegant to find the current page's file name:
var fileName = location.href.split("/").slice(-1);
or...
var fileName = location.pathname.split("/").slice(-1)
This is cool to customize nav box's link, so the link toward the current is enlighten by a CSS class.
JS:
$('.menu a').each(function() {
if ($(this).attr('href') == location.href.split("/").slice(-1)){ $(this).addClass('curent_page'); }
});
CSS:
a.current_page { font-size: 2em; color: red; }
Solution 3 - Javascript
Try this
location.pathname.substring(location.pathname.lastIndexOf("/") + 1);
location.pathname gives the part (domain not included) of the page URL. To get only the filename you have to extract it using the substring method.
Solution 4 - Javascript
Use: location.pathname
alert(location.pathname);

Solution 5 - Javascript
This will work even if the url ends with a /
:
var segments = window.location.pathname.split('/');
var toDelete = [];
for (var i = 0; i < segments.length; i++) {
if (segments[i].length < 1) {
toDelete.push(i);
}
}
for (var i = 0; i < toDelete.length; i++) {
segments.splice(i, 1);
}
var filename = segments[segments.length - 1];
console.log(filename);
Solution 6 - Javascript
Use window.location.pathname
to get the path of the current page's URL.
Solution 7 - Javascript
Get Document Name
location.href.split("/").pop().split("?").shift();
With Query String
location.href.split("/").pop()
Solution 8 - Javascript
Single statement that works with trailing slash. If you are using IE11 you'll have to polyfill the filter
function.
var name = window.location.pathname
.split("/")
.filter(function (c) { return c.length;})
.pop();

@Ethan's solution was what I needed but I had to make some changes. Namely, the elements in the toDelete array don't take into account that removing an element from the array segments decrease their number. So here are my two pence:
let segments = window.location.pathname.split('/');
let toDelete = [];
for (let i = 0; i < segments.length; i++) {
if (segments[i].length < 1) {
toDelete.push(i);
}
for (let i = 0; i < toDelete.length; i++ ) {
segments.splice(toDelete[i], 1);
for (let j = i; j < toDelete.length; j++ ) {
(toDelete[j])--;
}
}
let filename = segments[segments.length - 1];
console.log(filename);
Solution 10 - Javascript
const page = location.href.split("/").slice(-1).toString().replace(".EXTENSION", "").split("?")[0];
This will get the page name also removing the extension (like .html or .php) and eventually all get parameters like (?id=1). If you haven't the extension you can remove the replace()
part, otherwise replace .EXTENSION with your preferred extension.
Solution 11 - Javascript
If you want to check if it has the path "indexOLD.html" at the end of URL, you can use this as well:
if(window.location.pathname.endsWith("indexODL.html")) {
// your code block here.
}
