商城首頁(yè)主要包含以下幾個(gè)部分

• 1.使用ion-slide實(shí)現(xiàn)首頁(yè)幻燈片颗祝；
• 2.使用ion-grid實(shí)現(xiàn)商品分類蓄愁；
• 3.使用ion-list實(shí)現(xiàn)商品列表嘱朽；

說(shuō)一下實(shí)現(xiàn)思路

• 1.先獲取網(wǎng)絡(luò)請(qǐng)求的數(shù)據(jù)轨帜，查看數(shù)據(jù)結(jié)構(gòu)转锈；
• 2.根據(jù)數(shù)據(jù)結(jié)構(gòu)來(lái)判斷需要展示的數(shù)據(jù)，編寫(xiě)html；
• 3.調(diào)整界面樣式衔憨，編寫(xiě)scss叶圃；

準(zhǔn)備工作

開(kāi)始之前請(qǐng)到阿里開(kāi)源圖標(biāo)庫(kù)準(zhǔn)備首頁(yè)需要的小圖標(biāo)，不想自己找的同學(xué)践图，在文章最后的交流群的群文件里有導(dǎo)出好的資源小圖標(biāo)掺冠，下載后直接放到項(xiàng)目的src/assets/icon/目錄中即可。
并在index.html的header節(jié)點(diǎn)中導(dǎo)入資源圖標(biāo)庫(kù)码党；
