Question

我正在使用最新的nodewebkit并按照文档（https://github.com/rogerwang/node-webkit/wiki/Screen）运行以下代码，但它总是失败。任何人都可以告诉我为什么我有这个错误，你怎么解决它？

<!DOCTYPE html>
<html>
<body>
    <script>
      function ScreenToString(screen) {
        var string = "";
        string += "screen: "+ screen.id;
        return string;
      } 

      var gui = require('nw.gui');
      gui.Screen.Init();
      var string  = "" ; 
      var screens = gui.Screen.screens;

      for(var i=0;i<screens.length; i++) {
        string += ScreenToString(screens[i]);
      }
      document.write(string);
    </script>
</body>
</html>

错误：

Uncaught node.js Error 

SyntaxError: Unexpected end of input

    at Screen.screens (screen.js:65:15)

此脚本将窗口移动到另一个屏幕的中心（如果有的话）。

var gui = require('nw.gui');

// initialize the Screen singleton
gui.Screen.Init();

// get the current window
var win = gui.Window.get();

function moveToOtherWindow() {
    for(var i = 0; i < gui.Screen.screens.length; i++) {
        var screen = gui.Screen.screens[i];
        // check if the window is horizontally outside the bounds of this screen
        if (win.x < screen.bounds.x || win.x > screen.bounds.x + screen.bounds.width) {
            // move the window to this screen
            win.x = screen.bounds.x + (screen.bounds.width - win.width) / 2;
            win.y = screen.bounds.y + (screen.bounds.height - win.height) / 2;
            break;
        }
    }
}

moveToOtherWindow();

node webkit - 文档说屏幕可以工作，但是它不可能使它工作
