/**
|
||
* 使用方法：
|
||
* 1.脚本顶部引入 const app = getApp();
|
||
* 2.Utils.$router.push(name,params,type,openMode)
|
||
* -1）params为传入参数和值，如果params有值，将存在本地存储中
|
||
* -2）如果type（默认为params）为query时，参数会拼接到url后面
|
||
* -3）openMode 开发方式 默认navigateTo
|
||
* 3.Utils.$router.reLaunch(name,params,type)//打开到应用内的某个页面,可跳转到Tabbar页面
|
||
* 4.Utils.$router.redirect(name,params,type)//打开到应用内的某个页面,不可重定向到Tabbar页面
|
||
* 5.Utils.$router.switchTab(name)//跳转指定的tab页
|
||
* 6.Utils.$router.back(deltah,params)//返回上n级页面
|
||
* 7.Utils.$router.backHome(params)//返回到首页
|
||
* 8.Utils.$router.webviewRedirect(name, params, openMode)//跳转到webview页面
|
||
* 9.Utils.$router.openUrlScheme //传入url结构解析后跳转
|
||
* 10.链式调用success，fail，complete，
|
||
* 例：Util.$router.push("mine")
|
||
