代碼如下:
//--------------------------------------------
// 刪除千分點。
//--------------------------------------------
function removeComma(number) {
var num = number.replace(new RegExp(",","g"),"");
if(/^[-+]?[0-9]+(/.[0-9]+)?$/.test(num)) {
return num;
} else {
return number;
}
}
//--------------------------------------------
//添加千分點。
//--------------------------------------------
function addKannma(number) {
var num = number.replace(new RegExp(",","g"),"");
// 正負號處理
var symble = "";
if(/^([-+]).*$/.test(num)) {
symble = num.replace(/^([-+]).*$/,"$1");
num = num.replace(/^([-+])(.*)$/,"$2");
}
if(/^[0-9]+(/.[0-9]+)?$/.test(num)) {
var num = num.replace(new RegExp("^[0]+","g"),"");
if(/^/./.test(num)) {
num = "0" + num;
}
var decimal = num.replace(/^[0-9]+(/.[0-9]+)?$/,"$1");
var integer= num.replace(/^([0-9]+)(/.[0-9]+)?$/,"$1");
var re=/(/d+)(/d{3})/
while(re.test(integer)){
integer =integer.replace(re,"$1,$2")
}
return symble + integer + decimal;
} else {
return number;
}
}
