使用chrome浏览器的存储，我想出了如何在标签之间传输数据。 Content.js在新打开的烂番茄选项卡上搜索评级，使用chrome.storage.local.set存储它们，以便popup.js访问并显示在活动选项卡上。

popup.js

 $(document).ready(function(){ function d(c){ console.log(c) } $('#rt').click(function(){ var mov = $('input:text').val() //open new link with movie title name var movUpdate = mov.replace(/ /g,'_') var link = "http://www.rottentomatoes.com/m/" + movUpdate chrome.tabs.create({"url":link,"active":false}) }) chrome.storage.onChanged.addListener(function(changes, areaName) { //updates the ratings // Do whatever you want with the changes. console.log('changed!') chrome.storage.local.get("keyName",function(items) { console.log(items) console.log(items.keyName) var criticsscore = items.keyName[0] var audiencescore = items.keyName[1] $('#criticsscore').html('Critics ' + criticsscore) $('#audiencescore').html('Audience ' + audiencescore) $('#title').html(items.keyName[2]) // Do something with items.keyName }); }); chrome.storage.local.get("keyName",function(items) {//initialize the application console.log(items) console.log(items.keyName) var critics = items.keyName[0] var people = items.keyName[1] $('#criticsscore').html('Critics ' + critics) $('#audiencescore').html('Audience ' + people) $('#title').html(items.keyName[2]) // Do something with items.keyName }); })

 var ratings = document.getElementsByClassName("meter-value") var critics = ratings[0].innerText var audienceIndex = ratings.length - 1 var audience = ratings[audienceIndex].innerText var title = document.getElementById("movie-title").innerText chrome.storage.local.set({"keyName": [critics,audience,title]},function(){console.log('mah critics stored')});
