javascript - Use vue.js to achieve the effect: click li, get the html value of the current click li, and the parameter this becomes the window object?

The effect to be achieved:

Main code

<body>
<p id="page">
    <ul>
        <li v-on:click="aa(this)" v-for="item in items">{{item}}</li>
    </ul>
</p>
<script type="text/javascript">
new Vue({
  el: '#page',
  data: {
        items:[11,22,33,44]
  },
  methods:{
    aa:function(obj){
        console.log(obj);  //打印出来的是 window对象？
        alert(obj.html());   //找不到点击的值；
    }
  }
})
</script>
</body>

Problem Description:

The this passed after clicking li is printed as the window object, not the li object, so the object cannot be found; how to pass the current li object to js?

    Read the documentation carefully...don't make assumptions about these inexplicable usages.

    When an inline event needs to access the original event object, just add the $event parameter to it. Like this: 

    <li v-on:click="aa($event)" v-for="item in items">{{item}}</li>

    To get the object of the current li tag, just read the currentTarget attribute under the event object, that is, event.currentTarget.

    <li @click="aa(item)" v-for="item in items">{{item}}</li>
    aa(item) {
  console.log(item) // 当前li的内容
}

    Add a ref attribute to li and then get the dom node through this.$refs in methods

    Test possible: 

    <li @click="aa($event)" v-for="item in items">{{item}}</li>
      methods:{
    aa:function(event){
        console.log(event.target.innerHTML);
    }
  }
