javascript - 如何获取数组的值并将其与 window.locaton 匹配

Question

我想在循环中删除部分字符串，然后我必须检查它是否等于 window.location。

linkAdd= 应该返回一个数组。但它看起来像它返回一个字符串。那么如何检查网站上是否有等于 adresPath var 的点赞？如何创建一个包含所有 /123/1.php、/123/2.php、/123/3.php 而不仅仅是一个 /123/1.php 的 var？然后检查/123/1.php是否等于adresPath变量？

我试图删除每个元素上域的第一部分。通过真正的他们。并做.replace。但它似乎没有返回一个数组。要获得清晰的解释，请检查代码。

var adresPath = window.location.pathname; 
var link      = $('.menu-item>a');
var linkAdres = $('.menu-item>a').href;
var linkAdd   =  $('.menu-item>a').href.replace("http://bertconinx.com/","")
//link linkAdres and linkadd should be arrays. but when i try linkadd[i] it returns a letter of the string.

//ther are 19 a href in my code.


for(i = 0; i < link.length; i++){
    var linkAdd   = link[i].href.replace("http://bertconinx.com/","")
    };

if(adresPath=linkAdd[i]){alert(happy happy it works!)};```

Answer 1

这是你可以用普通的 javascript 做的事情

const links = document.getElementsByClassName('menu-item');
const anchors = [];
for (let i = 0; i < links.length; i++) {
    anchors.push(links[i].getElementsByTagName('a')[0]); 

}

const linkAddresses = [...anchors].map(anchor => anchor.href.replace("http://bertconinx.com/",""));

现在你将["category/portriats/", "2019/08/12/non-profit-profit/", "2019/09/16/girls/", "category/portriats/", "2019/08/12/non-profit-profit/", "2019/09/16/girls/"]在你的linkAddress变量中有一个数组。现在您可以遍历此数组并查找是否有任何链接与addresPath

linkAddresses.forEach(address => {
    if (address === adresPath) {
        // matches
    }
})
