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 again          
            if (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 found
function withLateElement(selector, doAction)
{   
    //checks to see if this element is already being waited for                             
    if (!(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 code is the code you want to inject, the one that replaces the ajax methods
document.head.appendChild(script); //make sure document.head is already loaded before doing it
script.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
    };
})();
