JS实现金额转换(将输入的阿拉伯数字)转换成中文

// 数字转化为中文大写
            number_chinese:function (str) {
                    var num = parseInt(str);
                    var strOutput = "",
                        strUnit = ‘仟佰拾亿仟佰拾万仟佰拾元角分‘;
                    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 += ‘零壹贰叁肆伍陆柒捌玖‘.substr(num.substr(i,1),1) + strUnit.substr(i,1);
                    }
                    return 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")

            }
