在 href 中查找包含特定字符串的链接,并仅删除带有 javascript 的斜杠之间的 href

Fnd links containing particular string in href and remove href between slashes with javascript only

我有一个用例,我必须 select 所有 <a>,在 url 中包含字符串,例如“/web/local”,并删除“[=18=” ]" 来自所有这些链接的所有 href。

注意:我无法使用 jQuery。我可以使用纯 js 或 YUI。

提前致谢。

查看内联评论:

let phrase = "/web/local";

// Get all the links that contain the desired phrase into an Array
let links = Array.prototype.slice.call(document.querySelectorAll("a[href*='" + phrase +"']"));

// Loop over results
links.forEach(function(link){
  // Remove the phrase from the href
  link.href = link.href.replace(phrase, "");
});

// Just for testing:
console.log(document.querySelectorAll("a"));
<a href="http://www.something.com/web/local">Some Link</a>
<a href="http://www.something.com/web/local">Some Link</a>
<a href="http://www.something.com/web/local">Some Link</a>
<a href="http://www.something.com/web/local">Some Link</a>
<a href="http://www.something.com/web/local">Some Link</a>

为了正确获取/设置 href 属性,您需要使用 getAttribute/setAttribute:

document.querySelectorAll('a[href*="/web/local"').forEach(function(ele) {
  ele.setAttribute('href', 
           ele.getAttribute('href').replace('/web/local', ''));

    console.log(ele.outerHTML);
});
<a href="/web/local"></a>
<a href="22222/web/local"></a>
<a href="/web/local"></a>
