vue中防止防止重复提交

<div id="app">
      <button @click="submit"  :disabled="isDisable">点击</button>
</div>


data(){
   return{
      isDisable:false
   }
}
methods:{
    submit(){
       this.isDisable=true
       setTimeout(()=>{
           this.isDisable=false   //点击一次时隔两秒后才能再次点击
       },2000)
    }
}
