vue 子組件里面data 有多個(gè)數(shù)組的話不能同時(shí)循環(huán)遍歷嗎

Component template should contain exactly one root element.
樓上已經(jīng)說(shuō)了 只能有一個(gè)根元素

多個(gè)數(shù)組遍歷是可以的，沒(méi)有限制。
報(bào)錯(cuò)信息是什么？
你的模版有問(wèn)題，<template>里只能有一個(gè)根元素，所以你應(yīng)該再嵌套一個(gè)<div>

謝邀??！
樓上已經(jīng)說(shuō)明了問(wèn)題所在，奈何還未解決，直接復(fù)制替換你上面的那些內(nèi)容便可看到效果！
