首先需要在Vue实例中定义属性
按钮未被禁用

Html:

<div>
<button @click="submit()" :disabled="isDisable">点击</button>
</div>

JavaScript:

var vm = new Vue({
    el: "#app",
    data:{
    isDisable: false
    },
    methods: {
    disabel:function(){
    //点击按钮之后禁用按钮
    this.isDisable = true
    //处理
    ......
    //
    setTimeout(() => {
        this.isDisable = false
    }, 2000)
    },
    },
})
