1.event.target: 触发事件的具体控件,不产生冒泡作用,是谁就是谁,这个在锁定事件触发的控件时经常用到,比如:
<div @click.stop = "addItem($event)">
<span data-type = "radio">单选题</span>
<span data-type = "checkbox">多选题</span>
<span data-type = "textarea">文本题</span>
</div>
<script>
export default{
method: {
addItem(event){
let target = event.target
if(target.nodeName.toLowerCase() === 'span') { // 当点击了选择的按钮后
this.showMask = true // 显示弹出框
this.questItem.type = target.dataset.type // 设置问题的类型
}
}
}
</script>
