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：
//金额转换成大写
functiontoDaX(num){
//金额大小写转换
if(isNaN(num)||num>Math.pow(10,12))
return"";
varcn="零壹贰叁肆伍陆柒捌玖";
varunit=newArray("拾佰仟","分角");
varunit1=newArray("万亿","");
if(parseFloat(num)==0||num==''){
return"零圆";
}
varnumArray=num.toString().split(".");
varstart=newArray(numArray[0].length-1,2);
functiontoChinese(num,index){
varnum=num.replace(/\d/g,function($1){
returncn.charAt($1)+unit[index].charAt(start--%4?start%4:-1);
});
returnnum;
}
for(vari=0;i<numArray.length;i++){
vartmp="";
for(varj=0;j*4<numArray[i].length;j++){
varstrIndex=numArray[i].length-(j+1)*4;
varstr=numArray[i].substring(strIndex,strIndex+4);
varstart=i?2:str.length-1;
vartmp1=toChinese(str,i);
tmp1=tmp1.replace(/(零.)+/g,"零").replace(/零+$/,"");
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";
returnnumArray[0]+numArray[1];
}

/**字符格式化添加空格分隔符*/ functionaddSpace(value){ if(value==null||value==""){ return""; }
