tab功能的实现需要在项目根目录下app.json文件中配置,创建tab时，需要准备相应的图标文件和新建对应的页面，然后就可以在对应页面中写项目原型了。下面是一个简单的tab实现，直接可以拷贝到项目中使用，没有多余的代码。
效果图：
示例代码：
"tabBar": {
"selectedColor": "#20B3AD",
"color": "#999",
"borderStyle": "white",
"backgroundColor": "#F0F0F0",
"list": [
{
"pagePath": "pages/index/index",
"iconPath": "images/home.png",
"selectedIconPath": "images/homeSelected.png",
"text": "首页"
},
{
"text": "租赁",
"pagePath": "pages/lease/lease",
"iconPath": "images/lease.png",
"selectedIconPath": "images/leaseSelected.png"
},
{
"text": "预售",
"pagePath": "pages/sale/sale",
"iconPath": "images/sale.png",
"selectedIconPath": "images/saleSelected.png"
},
{
"pagePath": "pages/my/my",
"iconPath": "images/mine.png",
"selectedIconPath": "images/mineSelected.png",
"text": "我的"
}
]
}
