How can I get the name of an html page in Javascript?

Question

I have an html page and I would like inside the html page to retrieve the name of the html document via Javascript. Is that possible?

eg name of html document = "indexOLD.html"

Answer 1

var path = window.location.pathname;
var page = path.split("/").pop();
console.log( page );

Answer 2

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; }

Answer 3

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.

Answer 4

Use: location.pathname

alert(location.pathname);

Answer 5

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);

Answer 6

使用window.location.pathname获取当前页面 URL 的路径。

Answer 7

Get Document Name

location.href.split("/").pop().split("?").shift();

With Query String

location.href.split("/").pop()

Answer 8

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();

Answer 9

@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);

Answer 10

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.

Answer 11

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.
}
