   //num为小写金额，单位元

    changeMoney(num) {

        if(isNaN(num))return "";

        var strPrefix="";

        if(num<0)strPrefix ="(负)";

        num=Math.abs(num);

        if(num>=1000000000000)return "";

        var strOutput = "";

        var strUnit = '仟佰拾亿仟佰拾万仟佰拾元角分';

        var strCapDgt='零壹贰叁肆伍陆柒捌玖';

        //将单位转换为分

        num += "00";

        var intPos = num.indexOf('.');

        if (intPos >= 0){

            num = num.substring(0, intPos) + num.substr(intPos + 1, 2);

        }

        strUnit = strUnit.substr(strUnit.length - num.length);

        for (var i=0; i < num.length; i++){

            strOutput += strCapDgt.substr(num.substr(i,1),1) + strUnit.substr(i,1);

        }

        return strPrefix+strOutput.replace(/零角零分$/, '整').replace(/零[仟佰拾]/g, '零').replace(/零{2,}/g, '零').replace(/零([亿|万])/g, '$1').replace(/零+元/, '元').replace(/亿零{0,3}万/, '亿').replace(/^元/, "零元");

    },
