如何通过JQuery从没有扩展名的URL获取页面名称 [英] How to get the pagename from the URL without the extension through JQuery

问题描述

我有一个网址： -

I have a URL:-

http://www.example.com/keyword/category.php

或

http://www.example.com/keyword/category.php#4

我需要一个神奇的abracadabra，它只给我这个网址中的类别页面名称。

I need a magic abracadabra which gives me only the pagename as category from this URL.

这是我尝试过的，它给出了类别.PHP 即可。但它有两个问题。这是丑陋和漫长的，它给我带有扩展名的文件名。

Here is what I tried, and it gives category.php. But it has two problems. It is ugly and long and it gives me filename with an extension.

var currurl = window.location.pathname;
var index = currurl.lastIndexOf("/") + 1;
var filename = currurl.substr(index);

谢谢。

推荐答案

只需将其转换为如下函数：

Just make this into a function as below:

function getPageName(url) {
    var index = url.lastIndexOf("/") + 1;
    var filenameWithExtension = url.substr(index);
    var filename = filenameWithExtension.split(".")[0]; // <-- added this line
    return filename;                                    // <-- added this line
}

然后当你需要使用它时：

Then when you need to use it:

var url = "http://www.example.com/keyword/category.php";
var myFilename = getPageName(url);

所有丑陋都隐藏在一个函数中，主代码看起来很干净！

All of the "ugliness" has been hidden in a function and the main code looks nice and clean!
