Javascript Java-在browser.execute（脚本）中使用方法

我有一个包含名称的数组的方法，我使用SWT Browser和

Browser.execute（）

我想填写表单

我的问题: 我想在

浏览器中使用
generateName（）
方法。execute（）

部分而不是TEST as value

方法

/**
 * generate name, lastname
 */
public void generateName() {
   Random generateName = new Random();
   String[] name = {"Liam", "Elias", "Kevin", "Julian", "Linus", "Levi", "Jonas", "Daniel", "Milan", "Maria", "Alexander", "Manfred", "Max", "Jens", "Dennis", "Oliver", "Jan", "Bob", "Henry"};
   String[] lastname = {"Meyer", "Müller", "Eilers", "Gerdes", "Schröder", "Janssen", "Ahlers", "Bruns", "Behrens", "Harms", "Schmidt", "Macke", "Kruse", "Becker", "Lange", "Suhr", "Schulte", "Weber", "Lampe"};

   // debug
   System.out.println(name[generateName.nextInt(19)] + " " + lastname[generateName.nextInt(19)]);
}

带listner的按钮

/**
 * Create contents of the window.
 */
protected void createContents() {
    shell = new Shell();
    shell.setSize(800, 600);
    shell.setText("SWT Application");

    Browser browser = new Browser(shell, SWT.NONE);
    browser.setUrl("www.pseudopage.com/SignUp");
    browser.setBounds(10, 10, 780, 352);

    Button btnNewButton = new Button(shell, SWT.BORDER);
    btnNewButton.addSelectionListener(new SelectionAdapter() {
        public void widgetSelected(SelectionEvent e) {
            browser.execute("document.getElementById('txtFirstName').value=\"TEST\"");
        }
    });
    btnNewButton.setBounds(10, 374, 94, 28);
    btnNewButton.setText("Generate");

}

我不确定我是否理解你的问题。。希望我有：

你可以：

browser.execute("document.getElementById('txtFirstName').value=\"" + generateName() + "\"");

但是generateName必须返回一个值，而不是打印它

public String generateName() {
   Random generateName = new Random();
   String[] name = ...
   String[] lastname = ...

   return name[generateName.nextInt(19)] + " " + lastname[generateName.nextInt(19)];
}

成功了！将方法更改为String而不是void，当然返回。非常感谢。
