补充

获取页面显示的安全距离

封装的公共函数--用于获取手机端的安全可视距离(顶部top和底部bottom)

    /**
	 * @description 获取页面的安全显示区域
	 * @returns { object } 返回的安全top，bottom
	 */
	setSafeDistance(){
		let app = uni.getSystemInfoSync()
		let top = app.statusBarHeight+'px'
		let bottom = app.safeAreaInsets.bottom+'px'
		let safe = {
			top:top,
			bottom:bottom
		}
		return safe;
	}

进行页面点击跳转

 官网文档：uni.navigateTo(OBJECT) | uni-app官网

注意：

1、path的跳转路径前要加 " / "

2、pages.json文件夹要对tabBar进行配置要不不进行跳转

"tabBar": {
	"height": "1px",
	"custom": true,
	"list": [
		{
			"pagePath": "pages/bookkeeping/bookkeeping",
			"text": ""
		},
		{
			"pagePath": "pages/wealth/wealth",
			"text": ""
		}
	]
}

scss简化媒体查询

//媒体查询响应式开发
@mixin mediaModel($model:'pc'){
	@if $model == "pc"{
		@media (min-width:481px){
			@content;
		}
	}@else{
		@media (max-width:480px){
			@content;
		}
	}
}
