在开发的过程中，用到了节流，引入公共的节流，初始调用如下（报错了…）。 template中：
<button class="btn" @click="throttle(Submit(),500,2)" :disabled="!normalUse">创建</button>JS文件只是引入：
import {throttle} from '../../../../utils/index'以上代码，执行后的结果：
vconsole.min.js?aac1:10 [Vue warn]: Property or method "throttle" is not defined on the instance but referenced during render. Make sure that this property is reactive, either in the data option, or for class-based components, by initializing the property.

解决方法如下： 写法错误，不能写在template中，要写在js代码块中，所以改动了下： template:
<button class="btn" @click="toCreate" :disabled="!normalUse">创建</button>js 代码：
import {throttle} from '../../../../utils/index'; //引入节流 toCreate(){ throttle(this.Submit(),400,2); },这样就可以了，完成
