使用方式

在template中引入

<show-toast></show-toast>

在需要使用show-toast的地方使用

this.$showToast({
				title:"操作失败",
				content:"",
				icon:'fail',
				success:res=>{
					console.log("[dsdhfdhsh]")
				}
			});

在main.js中挂在组件

import initToast from "@/components/show-toast/initToast.js"
import showToast from "@/components/show-toast/show-toast.vue"

initToast(Vue);
Vue.component('show-toast',showToast);

文件代码：组件show-toast

show-toast/show-toast.vue
