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：

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]; } /** 金额格式化添加“,”分隔符 */

money=money.replace(/^(\d*)$/,"$1."); money=(money+"00").replace(/(\d*\.\d\d)\d*/,"$1"); money=money.replace(".",","); var re=/(\d)(\d{3},)/; while(re.test(money)){ money=money.replace(re,"$1,$2"); } money=money.replace(/,(\d\d)$/,".$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,""); }

/** * 金额格式化字符串添加小数点 */ function addPoint(money){ if(/[^0-9\.]/.test(money)){ return money; }

if(money.length < 3 || money.indexOf(".") > -1){
return money;
}

return money.substring(0,money.length - 2) + "." + money.substring(money.length - 2,money.length);
}
/**

金额格式化数字去小数点
*/
function removePoint(money){
if(/[^0-9.]/.test(money)){
return money;
}

var valueFloat = parseFloat(money) 100;
var valueInt = parseInt(valueFloat);
return valueInt;
}
/ 格式化小数点后两位数字以百分比显示 /
function addPercent(str){
var percent = Math.floor(str 100) / 100;
percent=(percent.toFixed(2));
return percent+'%';
}

/** 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(0,8) +

" " + 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]); }
