我正在尝试使用Electron(以前的Atom Shell)为Twitter编写一个包装器.
我的main.js文件(它看起来几乎与“Hello World”示例相同,我只是在一个地方更改了它):
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;
});
});
我尝试在mainWindow.loadUrl()之后立即调用alert()函数,但它不执行.
我知道main.js文件就像我的应用程序的服务器端,但问题是……如何在页面上调用JavaScript函数?我应该在哪里写代码?
例如,我想执行此操作:
$(document).ready(function() {
alert("Hurray!");
});
解决方法:
我已经解决了这个问题.这是示例代码:
...
app.on('ready', function() {
...
mainWindow.webContents.on('did-finish-load', function() {
mainWindow.webContents.executeJavaScript("alert('Hello There!');");
});
...
});
