這篇文章主要介紹微信小程序如何實(shí)現(xiàn)聯(lián)動(dòng)菜單,文中介紹的非常詳細(xì),具有一定的參考價(jià)值,感興趣的小伙伴們一定要看完!
第1步:了解一下
左右側(cè)菜單其實(shí)簡(jiǎn)單來講就是把一個(gè)區(qū)域分成左右兩個(gè)部分。關(guān)于組件,我覺得可以直接去微信開發(fā)文檔看。通過代碼,我覺得應(yīng)該是可以理解的。直接上代碼。
第2步:先看一下效果啦
運(yùn)行效率還是可以的很快,無卡頓現(xiàn)象。
第3步:實(shí)現(xiàn)(代碼)
這里我只放了其中一部分,也是可以直接實(shí)現(xiàn)的,沒有問題,可以根據(jù)自己的需要修改。
