<template>
	<view>
		首页
		<u-tabbar
		:list="tabBar" 
		@change="changeEvent()" 
		bg-color="rgb(51, 61, 73)"
		active-color="rgba(8,141,246, 1)"
		inactive-color="#fff">
		</u-tabbar>
	</view>
</template>

<script>
	export default {
		data() {
			return {
				tabBar: '',
			}
		},
		onLoad() {
			this.tabBar = [{
					// pagePath(需以"/"开头)属性即可
					pagePath: "/pages/index/index",
					iconPath: "home",
					selectedIconPath: "home-fill",
					text: '首页',
				},
				{
					pagePath: "/pages/release/release",
					iconPath: "https://cdn.uviewui.com/uview/common/min_button.png",
					selectedIconPath: "https://cdn.uviewui.com/uview/common/min_button_select.png",
					text: '发布',
					 // 在此配置midButton: true   在<u-tabbar 标签内配置  :mid-button="true"  表示此项为凸起按钮项
					// midButton: true,
				},
				{
					pagePath: "/pages/user/user",
					iconPath: "account",
					selectedIconPath: "account-fill",
					text: '我的',
					// isDot 为 true 时 “首页”角标将会以红点的形式显示 2
