单击按钮时隐藏表单字段

对不起,我的英语不好。

我有一种形式,当通过各种按钮调用时,应隐藏一些字段。

以下是按钮:

<a  data-target="#call">Button 1</a> 
<a  data-target="#call">Button 2</a>

这是表格:

<div id="call">
<form>
<div class="pole1">Field 1</div>
<div class="pole2">Field 2</div>
</form>
</div>

一个表单只能有一个ID,在我看来,这是一个“呼叫”。

如何在单击“按钮1”时仅显示“字段1”? 当您单击“按钮2”时仅显示“字段2”时,该怎么做?

请尝试这个

io.on('connection', (socket) => {
  //create canChannel with socketcan(node-can)
  var channel = can.createRawChannel('vcan0', true);

  //emit messagees to the *can message* listening to the canChannel
  socket.emit('can message', channel.addListener('onMessage', (data) => {
    io.emit('can message', data);
  }));

  channel.start();
  //disconnect
  socket.on('disconnected', (socket) => {
    console.log('socket disconnected');
  });

这是表格:

constructor() {
    this.socket = io();
    this.socket.on('can message', (msg) => {
      console.log('data', msg);
    });
  }

javascript代码:

<a  data-target="#call" onclick="show('id1');">Button 1</a> 
<a  data-target="#call" onclick="show('id2');">Button 2</a>

 <a href="#"   onclick='myFunction1()'>Button 1</a> 
<a href="#"   onclick="myFunction2()">Button 2</a>

<div id="call">
<form>
<div class="pole1" id="Field1Id">Field 1</div>
<div class="pole2"  id="Field2Id">Field 2</div>
