vue+uniapp 获取上一页直接传递的参数

在小程序里页面之间跳转有时候需要传递参数给下个页面用

const toDetail = item => {

uni.navigateTo({

url: `/pagesFood/stu/FoodSelection?groupCode=1&merchCode=2`,

});

};

那么下个页面就要获取到这些参数，在实际开发中，我们需要区分当前运行环境是小程序还是web浏览器，因为两个环境下获取方式有些差距

let groupCode = "";

let merchCode = "";

const routes = getCurrentPages();

const route = routesroutes.length - 1;

onMounted(() => {

const uniPlatform = uni.getSystemInfoSync().uniPlatform;

if(uniPlatform==="web"){

groupCode = route.$page.options.groupCode;

merchCode = route.$page.options.merchCode;

}else{

groupCode = route.options.groupCode;

merchCode = route.options.merchCode;

}

console.log("111===",groupCode,merchCode);

});
