Question

如果我在NWJS应用程序上使用window.open创建窗口，则该窗口似乎根本无法访问任何nodejs或nwjs模块。我该如何解决呢？

我使用document.write来编写页面的内容，因为根据代码运行的上下文它会有所不同。

 import java.io.*;

public class sort {

/**
 * @param args the command line arguments
 */
public static void main(String[] args) throws IOException{
    // TODO code application logic here
    //Declare BufferedReader
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

    //declare variables
    int x=0, y=0;
    double grade=0.0;
    String course;

    //ask user how many courses they completed
    System.out.println("How many courses have you completed?");
    //obtain answer
    int completed=Integer.parseInt(br.readLine());

    //declare array for course
    String courses[]=new String[completed];

    //ask user to enter the course names use a FOR loop for this
    for(int i=0;i<courses.length;i++)
    {            
        System.out.println("Please enter course name " + (i+1));
        course = br.readLine(); 
        System.out.println("What is the grade you got for " + course);
        //get their answer
        grade = Double.parseDouble(br.readLine());

    //end for loop

    //display to the user the high achievement award qualifiers:

    System.out.println("High-Ahcievement Award Qualifiers: \n");
    if(grade>93)
    {
        //output
    }
    else if(grade<70)
    {
        System.out.println("Needs Improvement:");
        //output
    }
    }
}
}

在app.js里面有：

    var fs = require("fs");
    var text = fs.readFileSync(myfolder);
text=text.toString();
    var wndo = window.open("about:blank", "", "scrollbars=1,width=300,height=500");
wndo.moveTo(screen.width/2-250,screen.height/2-175);

    wndo.document.write(`<!DOCTYPE html>
<html>
<head>
  <title>JS Coder</title>
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="editor/style.css"/>
</head>

<input  style="display:none;" name="file" id="fileDialog" type="file" onchange="openeditor()" />
<label class="button button1" for="fileDialog">Open</label>


<input style="display:none;" name="filesave" id="filesave" type="file" onchange="saveeditor()" nwsaveas />
<label class="button button1" for="filesave" >Save</label>

 <div id="content" contenteditable="true"></div>

<script src="editor/app.js"></script>
<script type="text/javascript">
  document.getElementById('content').innerHTML = "`+text+`"

</script>

</html>`);

有没有办法在该窗口中启用node / nwjs模块？如果没有，我如何在我的应用程序中打开一个新窗口，该窗口可以访问node / nwjs模块，一旦打开，就可以在其中执行代码？

您打开的窗口中唯一不是静态的部分是+ text + ...所以，您有一个几乎静态的HTML页面

这是可行的。像这样创建一个静态页面：

<!DOCTYPE html>
<html>
<head>
    <title>JS Coder</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body>
    <input  style="display:none;" name="file" id="fileDialog" type="file" onchange="openeditor()" />
    <label class="button button1" for="fileDialog">Open</label>

    <input style="display:none;" name="filesave" id="filesave" type="file" onchange="saveeditor()" nwsaveas />
    <label class="button button1" for="filesave" >Save</label>

    <div id="content" contenteditable="true"></div>
    <script src="editor/app.js"></script>
    <script type="text/javascript">
        function loadText(text) {
            document.getElementById('content').innerHTML = text;
        }
    </script>
</body>
</html>

让我们说它叫otherpage.html - 它也和你的“主页”在同一个文件夹中

现在，主页中的javascript是

    var fs = require("fs");
    var text = fs.readFileSync(myfolder);
    text=text.toString();
    var wndo = window.open("otherpage.html", "", "scrollbars=1,width=300,height=500");
    wndo.addEventListener('load', () => {
        wndo.loadText(text);
    });
    wndo.moveTo(screen.width/2-250,screen.height/2-175);

因此主页面等待加载其他页面，然后调用另一页loadText来加载文本

新窗口无法访问NWJS模块？
