function removeComma(number) {
var num = number.replace(new RegExp(",","g"),"");
if(/^[-+]?[0-9]+(.[0-9]+)?$/.test(num)) {

}
}
//--------------------------------------------
//添加千分点。

function addKannma(number) {
var num = number.replace(new RegExp(",","g"),"");
// 正负号处理
var symble = "";
if(/^([-+]).*$/.test(num)) {
symble = num.replace(/^([-+]).*$/,"$1");
num = num.replace(/^([-+])(.*)$/,"$2");
}

}
