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:
function addComma(money) { if(money==""){ return ""; } if(money){ money = money.trim(); } if(/[^0-9\.\-\+]/.test(money)){ return money; } money = parseFloat(money) + ""; if('NaN' == money){ return "0.00"; } var money_flag = ""; if(money.indexOf("-") != -1){ money = money.replace(/-/g,""); money_flag = "-"; }
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]); }
希望本文所述对大家的javascript程序设计有所帮助。
