js轉換金錢為中文單位元、萬元、億元、萬億

function unitConvert(num) {
    var moneyUnits = ["元", "萬元", "億元", "萬億"] 
    var dividend = 10000;
    var curentNum = num;
    //轉換數字 
    var curentUnit = moneyUnits[0];
    //轉換單位 
    for (var i = 0; i <4; i++) { 
        curentUnit = moneyUnits[i] 
        if(strNumSize(curentNum)<5){ 
            break;
        }
        curentNum = curentNum / dividend 
    } 
    var m = {num: 0, unit: ""} 
    m.num = curentNum.toFixed(2)
    m.unit = curentUnit;
    return m;
}

function strNumSize(tempNum){ 
    var stringNum = tempNum.toString() 
    var index = stringNum.indexOf(".") 
    var newNum = stringNum;
    if(index!=-1){
        newNum = stringNum.substring(0,index) 
    } 
    return newNum.length
}

調用並且得到返回值

var data=unitConvert(100000);
console.log(data.num+data.unit)
