Question

我有2个文本框和一个提交按钮。单击提交按钮，第一个文本框中的值应填入第二个文本框。您可以帮助我。谢谢你提前。

Answer 1

<input type="submit" onclick="triggerSubmit();" value="Submit" />

<script type="text/javascript">
  function trigerSubmit(e){
    var textbox1 = document.getElementById('textbox1');  
    var textbox2 = document.getElementById('textbox2');  

    textbox2.value = textbox1.value;
    textbox1.value = '';

    return false; // Prevent form auto submittal

  }
</script>

Answer 2

JTextField txtFld1 = new JTextField(10); // 10 columns
JTextField txtFld2 = new JTextField(10);
JButton btn = new JButton("Submit");

// Register action listener responsible for copying text
// from txtFld2 to txtFld1.
btn.addActionListener(new ActionListener() {
  public void actionPerformed(ActionEvent evt) {
    txtFld1.setTxt(txtFld2.getText());
  }
});
