我的目標是用本地擁有的自制文件替換網頁中的原始JavaScript文件。我找到了一個有趣的腳本here,我用它來適應我的目標。使用Greasemonkey替換/交換html文件中的JavaScript文件
// ==UserScript==
// @name JS_tamper
// @namespace namespace
// @include http://192.168.1.1/*
// @version 1
// @grant none
// @run-at document-start
// ==/UserScript==
var newJSFile = "http://localhost:8080/tamper.js"; //The JS file to load in replacment of old JS file
var oldJSFile = "http://192.168.1.1/menuBcm.js"; //The old JS file as it is named in inspect element (make sure its spelled EXACTLY the same)
var pattern = new RegExp(oldJSFile, "i"); //Create the RegExp pattern with the /i switch to make it case-insensitive
function injectScript(originalPage) { //Function injectScript replaces the file
console.log('Replace stage 2: Replace text matching', oldJSFile, 'with', newJSFile);
var moddedPage = originalPage.replace(pattern, newJSFile); //Modify the HTML code that we got, replacing the old JS file with the new one
document.open();
console.log('Replace stage 3: Write new HTML to page...');
document.write(moddedPage); //Write to the page the new HTML code
document.close();
}
setTimeout(function() { //Wait a bit for the page's HTML to load...
console.log('Replace stage 1: target HTML');
injectScript(document.documentElement.outerHTML); //Run function injectScript with the page's HTML as oldPage in the function
}, 1111);
但是控制檯日誌中從未達到3級大概是由於某種錯誤開口(document.open()
)文件或更換(.replace
)的腳本。
輸出:
//Replace stage 1: target HTML JS_tamper.user.js:29:5
//Replace stage 2: Replace text matching "http://192.168.1.1/menuBcm.js" with "http://localhost:8080/tamper.js"
有誰知道爲什麼我有這個問題或解決使用Greasemonkey的(或其它擴展名)這個問題也許是另一種方式?
如果您對某些相關文件感興趣,我已經在同一個項目上創建了另一個thread另一個(不同)問題。
謝謝您的回答!我應該用'window.a'替換一個東西嗎? – Clone
@Clone這只是一個例子。這取決於'oldJSFile'的內容。你甚至可以重寫一些本地API來提出一個錯誤。 – blackmiaool
