错误处理响应：TypeError：在chrome-extension中无法读取未定义的属性“ show”

问题描述

在contentScript.js上，我放了这段代码...

chrome.runtime.sendMessage({ todo: "showPage" });

和backgroundScript.js

chrome.runtime.onMessage.addListener(function(request,sender,senderResponse) {
  if (request.todo == "showPage") {
    chrome.tabs.query({ active: true,currentwindow: true },function(tabs) {
      chrome.pageAction.show(tabs[0].id);
    });
  }
});

这是manifest.json文件

{
  "manifest_version": 2,"name": "Startpage Chrome Extension","description": "The extension will replace/load additional CSS and override Startpage default style,it should look exactly (or almost) like Google.","version": "1.0.1","author": "OpenText","content_scripts": [
    {
      "matches": ["*://*.google.com/*"],"all_frames": true,"js": ["./jquery.js","./startpage.js"],"css": ["startpage.css"],"run_at": "document_start"
    }
  ],"background": {
    "scripts": ["./jquery.js","background.js"],"persistent": false
  },"icons": {
    "16": "icon.png","48": "icon.png","128": "icon.png"
  },"offline_enabled": true,"browser_action": {
    "default_icon": "icon.png","default_popup": "popup.html","default_title": "Startpage Extension"
  },"permissions": ["tabs","activeTab","storage","*://www.google.com/*"]
}

这是我得到的错误：“错误处理响应：TypeError：无法读取chrome-extension：//phgdcficdbmcpddkligkfkjjcognioik/background.js：17：25中未定义的属性“ show”

解决方法

只需将 **Inventory Model** func showStockList_byStockQuantity() -> [StockModel] { let allStocks = self.ofStock.sorted(byKeyPath: "name",ascending: true).distinct(by: ["name"]) var activeStocks:[StockModel] = [] for stock in allStocks.enumerated() { let stockQuantity:Int = realm!.objects(StockModel.self).filter("name == %@",stock.element.name).sum(ofProperty: "quantity") if stockQuantity > 0 { activeStocks.append(stock.element) } } return activeStocks } 中的“browser_action”更改为“page_action”。
