javascript - 如何在 vue js 上传递 id @click ？

Question

我想通过 this.id 参数传递 id 但我无法发送和接收它。如何在 vue.js 上发送 this.id 作为参数？

<button 
    id="txt"
    @click="activate(this.id)"
    class="kind-btn"
    type="button"
>
    <i class='fas   fa-poll-h kind-icon'></i>
</button>
<button
    id="pic"
    @click="activate(this.id)"
    class="kind-btn"
    type="button"
    style="padding-left: 15px;"
>
    <i class='fas fa-image kind-icon'style="font-size: 30px;"></i>
</button>
<button
    id="sound"
    @click="activate(this.id)"
    class="kind-btn"
    type="button"
>
    <i class="material-icons kind-icon"style="font-size: 31px;top: 8px;margin-bottom: 13px;">music_video</i>
</button>

//js

activate: function(i) {
  console.log(i);
  switch (i) {
    case "txt":
      $("#" + this).css({"background-color": "#fe5d87", "color": "white"});
      break;

    case "pic":
      $("#" + this).css({"background-color": "#fe5d87", "color": "white"});
      break;

    case "sound":
      $("#" + this).css({"background-color": "#fe5d87", "color": "white"});
      break;
    // 
    // default:
    //   $("#txt").css({"background-color": "#fe5d87", "color": "white"});
  }

Answer 1

https://v2.vuejs.org/v2/guide/events.html

您可以执行@click="activate"

methods: {
    activate: function (event) {
        console.log(event.target.id)
    }
}

如果您需要传递更多数据，另一种方法是传递事件

@click="activate('your custom data string', $event)"
