前端js,ts小写数字转大写

简单的处理就是用一个键值对来匹配

写好对应的键值对：

const state = reactive({
    smallBigDic: {
        1: "一",
        2: "二",
        3: "三",
        4: "四",
        5: "五",
        6: "六",
        7: "七",
        8: "八",
        9: "九",
        10: "十",
        11: "十一",
        12: "十二",
    }
})

写好转化方法：

const methods = {
    numberSmallToBig: function (_num) {
        let big = state.smallBigDic[_num]
        if (big) {
            return big
        }
        else {
            return _num
        }
    }
}

页面上使用：

methods.numberSmallToBig(chapterItem.chapterOrder)
