Vue封装--如何将数字转换成万_vue.js_

 // 万转化 methods:{ formatDecimal(num, decimal) { num = this.fixeds(num * 1) num = num.toString(); let index = num.indexOf("."); if (index !== -1) { num = num.substring(0, decimal + index + 1); } else { num = num.substring(0); } return parseFloat(num).toFixed(decimal); }, } 

 methods: { // 升降顺序 saleamount(row) { return this.formatDecimal(Math.abs(row.month_amount * 1 - row.last_month_amount * 1) / 10000, 1) }, 

{{saleamount(scope.row)}}万

// 保留自定义小数 Vue.prototype.fixeds = function (num,count) { var decimal = 2 if(count == undefined || count == null){ decimal = 2 }else{ decimal = count } var numbers = ''; // 保留几位小数后面添加几个0 for (var i = 0; i < decimal; i++) { numbers += '0'; } var s = 1 + numbers; // 如果是整数需要添加后面的0 var spot = "." + numbers; // Math.round四舍五入 // parseFloat() 函数可解析一个字符串，并返回一个浮点数。 var value = Math.round(parseFloat(num) * s) / s; // 从小数点后面进行分割 var d = value.toString().split("."); if (d.length == 1) { value = value.toString() + spot; return value; } if (d.length > 1) { if (d[1].length < 2) { value = value.toString() + "0"; } return value; } } 

//将超过万/亿的数字加上万/亿的单位 getNum() { for (let i of this.paymentDiv) { //math.floor 就是去除小数点向下取整 math.floor(3.84) = 3 //x.toString() 就是把x变成字符串 let num1 = Math.floor(i.today).toString(); //如果num1长度大于4(num1是万级别的) if (num1.length > 4) { //如果num1长度大于8(num1是亿级别的) if (num1.length > 8) { //num1除以1亿再取整得到的数字再加'亿' let num2 = Math.floor(num1 / 100000000); i.total = num2 + "亿"; } else { //num1除以1亿再取整得到的数字再加'万' let num2 = Math.floor(num1 / 10000); i.total = num2 + "万"; } } } },
