本文實例講述了js實現格式化金額,字符,時間的方法。分享給大家供大家參考。具體實現方法如下：

//金額轉換成大寫
     function toDaX(num){
        //金額大小寫轉換
           if (isNaN(num) || num > Math.pow(10, 12))
                    return "";
           var cn = "零壹貳叁肆伍陸柒捌玖";
           var unit = new Array("拾佰仟", "分角");
           var unit1 = new Array("萬億", "");
           if(parseFloat(num)==0||num==''){
               return "零圓";
           }
           var numArray = num.toString().split(".");
           var start = new Array(numArray[0].length - 1, 2);
           function toChinese(num, index) {
               var num = num.replace(//d/g, function($1) {
                    return cn.charAt($1)+ unit[index].charAt(start-- % 4 ? start % 4 : -1);
                   });
               return num;
           }
           for ( var i = 0; i < numArray.length; i++) {
                var tmp = "";
                for ( var j = 0; j * 4 < numArray[i].length; j++) {
                   var strIndex = numArray[i].length - (j + 1) * 4;
                   var str = numArray[i].substring(strIndex, strIndex + 4);
                   var start = i ? 2 : str.length - 1;
                   var tmp1 = toChinese(str, i);
                   tmp1 = tmp1.replace(/(零.)+/g, "零").replace(/零+$/, "");
                   tmp1 = tmp1.replace(/^壹拾/, "拾");
                   tmp = (tmp1 + unit1[i].charAt(j - 1)) + tmp;
                }
               numArray[i] = tmp;
           }
           numArray[1] = numArray[1] ? numArray[1] : "";
           numArray[0] = numArray[0] ? numArray[0] + "元" : numArray[0],numArray[1] = numArray[1].replace(/^零+/, "");
           numArray[1] = numArray[1].match(/分/) ? numArray[1] : numArray[1] + "整";
           return numArray[0] + numArray[1];
     }
