jQuery + Greasemonkey:所有受影响的网站，不限于"window.location.href.indexOf"； [英] jQuery+Greasemonkey: All sites affected, not limited to "window.location.href.indexOf"

问题描述

我正在尝试让代码仅在特定的URL集上运行.对于我一生，我无法弄清楚为什么我单击的每个网站都会运行该代码，而不仅限于我所限制的网站.

I'm trying to have code ran only on specific set of URLs. For the life of me I can not figure out why every website I click, it runs the code, and not limited to the sites I limit it to.

// ==UserScript==
// @name        test
// @namespace   test1
// @description test2
// @include     https://*
// @version     1
// @grant       none
// @require     http://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js
// ==/UserScript==


$(document).ready(function () 
 {  if(   (!window.location.href.indexOf("https://www.youtube.com") > -1)  
        && (!window.location.href.indexOf("https://www.google.com") > -1)    
      )   
  {   
    alert("test");
  }
});

推荐答案

您已经关闭.只需尝试在数组中声明所有预期的url即可:

You were close. Just try declaring all the intended urls in an array :

JavaScript:

  var urls = [
    "https://www.youtube.com",
    "https://www.google.com",
    "https://fiddle.jshell.net",
  ];

  urls.forEach(function(v) {
    if (window.location.href.indexOf(v) >= 0) {
      alert("test");
    }
  });
