我可以想到两种方法：
1-使用计时器检查脚本是否仍然存在，否则，请再次添加…
2-检查ajax调用，如果它们的URL与删除脚本的URL之一匹配，请再次添加脚本。
即使在ajax调用之后，您的脚本（清单中定义的脚本）仍然存在，只是不再运行（不确定历史记录推送器会发生什么）。因此，我假设您只需要阅读一些元素或重新运行Stript。我以为您添加了附加html标记的脚本。
因此，您需要读取某些元素或重新运行某些代码。
1-计时器方法-我为希望添加到页面中某个 目标元素的* 任何元素 （不仅是脚本）创建了解决方案。 *
它使用计时器检查目标元素是否存在。当找到目标元素时，就添加我的元素。然后调整计时器以检查我的元素是否仍然存在。如果没有，请再次添加。
您只需
appendChildPersistent要打一次电话，这将在您浏览时始终保持活动状态。
var timers = {}; //stores the setInterval ids//this is the only method you need to call//give your script an `id` (1)//the child is your script, it can be anything JQuery.append can take//toElem is the Jquery "SELECtOR" of the element to add your script into.//I'm not sure what would happen if toElem were not a string.//callback is a function to call after insertion if desired, optional.appendChildPersistent = function(id, child, toElem, callback){ //wait for target element to appear withLateElement(toElem, function(target) { target.append(child); //appends the element - your script if (typeof callback !== 'undefined') callback(); //execute callback if any //create a timer to constantly check if your script is still there timers[id] = setInterval(function() { //if your script is not found, clear this timer and tries to add againif (document.getElementById(id) === null) { clearInterval(timers[id]); delete timers[id]; appendChildPersistent(id, child, toElem, callback); } },3000); });}//this function waits for an element to appear on the page//since you can't foresee when an ajax call will finish//selector is the jquery selector of the target element//doAction is what to do when the element is foundfunction withLateElement(selector, doAction){ //checks to see if this element is already being waited forif (!(selector in timers)) { //create a timer to check if the target element appeared timers[selector] = setInterval(function(){ var elem = $(selector); //checks if the element exists and is not undefined if (elem.length >= 0) { if (typeof elem[0] !== 'undefined') { //stops searching for it and executes the action specified clearInterval(timers[selector]); delete timers[selector]; doAction(elem); } } }, 2000); } }（1）在脚本标签中添加ID似乎不是问题：为脚本标签提供ID
2-捕获ajax调用
一种选择是使用chrome.webRequest。但是奇怪的是，这对我没有用。下面是另一个选择。
对于这种情况，请检查此答案， 不要忘 了在那里阅读与 Chrome扩展程序
相关的答案。只有遵循整个过程，它才起作用。幸运的是，我今天进行了测试，它效果很好：p
在这里，您要做的是更改
XMLHttpRequest方法
open并
send在调用它们时进行检测（并可能也获取参数）。
但是，在Google扩展程序中，绝对有必要 在页面中注入Stript （不是后台页面或脚本注入内容脚本，而是内容脚本向 dom中
注入一些代码，如下所示）。
var script = document.createElement('script');script.textContent = actualCode; //actual pre is the pre you want to inject, the one that replaces the ajax methodsdocument.head.appendChild(script); //make sure document.head is already loaded before doing itscript.parentNode.removeChild(script); //I'm not sure why the original answer linked removes the script after that, but I kept doing it in my solution这是至关重要的，因为该扩展程序试图创建一个隔离的环境，并且您
XMLHttpRequest对此环境所做的更改将完全不参与。（这就是为什么JQuery.ajaxComplete似乎不起作用的原因，您需要在页面中注入脚本才能使其工作-
请在此处查看）
在此纯Javascript解决方案中，您将替换方法：
//enclosing the function in parentheses to avoid conflict with vars from the page scope(function() { var XHR = XMLHttpRequest.prototype; // Store the orignal methods from the request var open = XHR.open; var send = XHR.send; // Create your own methods to replace those //this custom open stores the method requested (get or post) and the url of the request XHR.open = function(method, url) { this._method = method; //this field was invented here this._url = url; //this field was invented here return open.apply(this, arguments); //calls the original method without any change //what I did here was only to capture the method and the url information }; //this custom send adds an event listener that fires whenever a request is complete/loaded XHR.send = function(postData) { //add event listener that fires when request loads this.addEventListener('load', function() { //what you want to do when a request is finished //check if your element is there and readd it if necessary //if you know the exact request url, you can put an if here, but it's not necessary addMyElementsToPage(); //your custom function to add elements console.log("The method called in this request was: " + this._method); console.log("The url of this request was: " + this._url); console.log("The data retrieved is: " + this.responseText); }); //call the original send method without any change //so the page can continue it's execution return send.apply(this, arguments); //what we did here was to insert an interceptor of the success of a request and let the request continue normally };})();
