問(wèn)題描述

我正在嘗試使用 Twitter 編寫(xiě)一個(gè)包裝器.io/" rel="noreferrer">Electron(以前的 Atom Shell).

I'm trying to write a wrapper for Twitter using Electron (formerly Atom Shell).

我的 main.js 文件(它看起來(lái)幾乎與Hello World"的例子，我只是在一個(gè)地方改了):

My main.js file (it looks almost identical to the "Hello World" example, I just changed it in one place):

var app = require('app');  // Module to control application life.
var BrowserWindow = require('browser-window');  // Module to create native browser window.

// Report crashes to our server.
require('crash-reporter').start();

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the javascript object is GCed.
var mainWindow = null;

// Quit when all windows are closed.
app.on('window-all-closed', function() {
  if (process.platform != 'darwin')
    app.quit();
});

// This method will be called when atom-shell has done everything
// initialization and ready for creating browser windows.
app.on('ready', function() {

  // Create the browser window.
  mainWindow = new BrowserWindow ({'width':1000,'height':600});
  // and load the index.html of the app.
  mainWindow.loadUrl('https://twitter.com');

  // Emitted when the window is closed.
  mainWindow.on('closed', function() {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    mainWindow = null;
  });
});

我嘗試在 mainWindow.loadUrl() 之后立即調(diào)用 alert() 函數(shù)，但它沒(méi)有執(zhí)行.

I try to call alert() function right after mainWindow.loadUrl() but it does not execute.

我知道 main.js 文件就像我的應(yīng)用程序的服務(wù)器端，但問(wèn)題是……如何在頁(yè)面上調(diào)用 JavaScript 函數(shù)?我應(yīng)該在哪里寫(xiě)代碼?

I understand that main.js file is like the server side of my app, but the question is... How can I call a JavaScript function on page? Where should I write the code?

例如，我想執(zhí)行此操作:

For example, I want to perform this:

$(document).ready(function() {
    alert("Hurray!");
});

推薦答案

我已經(jīng)解決了這個(gè)問(wèn)題.下面是示例代碼:

I have solved the problem. Here's the example code:

...

app.on('ready', function() {

  ...

  mainWindow.webContents.on('did-finish-load', function() {
    mainWindow.webContents.executeJavaScript("alert('Hello There!');");
  });

  ...

});

這篇關(guān)于如何在 Electron 渲染的網(wǎng)頁(yè)上調(diào)用 JavaScript 函數(shù)?的文章就介紹到這了，希望我們推薦的答案對(duì)大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
