VUE报错

来源:互联网 发布:百合网淘宝女店主 编辑:程序博客网 时间:2024/06/05 02:56

报错:cannot read property 'forEach' of undefined  对象不是数组

报错:no-trailing-spaces  不允许在语句后存在多余的空格
报错:since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated  由props传入子组件的值不能被修改
