js实现格式化金额,字符,时间的方法

本文实例讲述了js实现格式化金额,字符,时间的方法。分享给大家供大家参考。具体实现方法如下：


代码如下:


//金额转换成大写
     function toDaX(num){
        //金额大小写转换
           if (isNaN(num) || num > Math.pow(10, 12))
                    return "";
           var cn = "零壹贰叁肆伍陆柒捌玖";
           var unit = new Array("拾佰仟", "分角");
           var unit1 = new Array("万亿", "");
           if(parseFloat(num)==0||num==''){
               return "零圆";
           }
           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];
     }

    money=money.replace(/^(d*)$/,"$1.");       money=(money+"00").replace(/(d*.dd)d*/,"$1");       money=money.replace(".",",");       var re=/(d)(d{3},)/;       while(re.test(money)){         money=money.replace(re,"$1,$2");       }       money=money.replace(/,(dd)$/,".$1");      var money =  money_flag+""+money.replace(/^./,"0.")     return money;           }
/** 金额格式化 去“,”分隔符 */ function delComma(value) {   var rtnVal = value + "";   return rtnVal.replace(/,/g,""); }

/** 字符格式化 添加 空格 分隔符 */ function addSpace(value) { if(value == null || value == ""){ return ""; }
    var value = value + "";     var tmpStr = "";     while (value.length > 4) {         tmpStr = tmpStr + value.substring(0,4)+ " ";         value = value.substring(4,value.length);     }     tmpStr = tmpStr + value;     return tmpStr; }
/** 字符格式化 去除 空格 分隔符 */ function removeSpace(value) { var rtnVal = value + "";   return rtnVal.replace(/ /g,""); }
// 格式化日期时间字符串 // YYYYMMDD-》YYYY-MM-DD // YYYYMMDDhhmmss-》YYYY-MM-DD hh:mm:ss function formatDatetime(oldvalue){ if(oldvalue == null){ return ""; }else if(oldvalue.length == 8){ return oldvalue.substring(0,4) +       "-" + oldvalue.substring(4,6) +       "-" + oldvalue.substring(6,8); }else if(oldvalue.length == 14){ return oldvalue.substring(0,4) +       "-" + oldvalue.substring(4,6) +       "-" + oldvalue.substring(6,8) +             " " + oldvalue.substring(8,10) +       ":" + oldvalue.substring(10,12) +       ":" + oldvalue.substring(12,14); }else if(oldvalue.length == 6){ return oldvalue.substring(0,2) +       ":" + oldvalue.substring(2,4) +       ":" + oldvalue.substring(4,6); }else{ return oldvalue; } }
function StringToDate(str){ var datainfo=str.split('-');     return new Date(datainfo[0],datainfo[1],datainfo[2]); }
