Vue中阿拉伯數字與漢字的相互轉換

numberfilter (num) { const changeNum = ['零', '一', '二', '三', '四', '五', '六', '七', '八', '九'] // changeNum[0] = "零" const unit = ['', '十', '百'] num = parseInt(num) const getWan = (temp) => { const strArr = temp.toString().split('').reverse() let newNum = '' for (var i = 0; i < strArr.length; i++) { newNum = (i == 0 && strArr[i] == 0 ?
