Js获取页面地址参数
function getUrlPara(paraName)
{
var sUrl = location.href;
var sReg = "(?://?|&){1}" + paraName + "=([^&]*)"
var re = new RegExp(sReg, "gi");
re.exec(sUrl);
return RegExp.$1;
}
地址跳转
var pn = $("#gotopagenum").val();//#gotopagenum是文本框的id属性
location.href = "NewList.aspx?pagenum="+pn;//location.href实现客户端页面的跳转
千分位
function Convert(money)
{
var s = money; //获取小数型数据
s += "";
if (s.indexOf(".") == -1) s += ".00"; //如果没有小数点,在后面补个小数点和00
if (/\.\d$/.test(s)) s += "0"; //正则判断
while (/\d{4}(\.|,)/.test(s)) //符合条件则进行替换
s = s.replace(/(\d)(\d{3}(\.|,))/, "$1,$2"); //每隔3位添加一个
return s;
}
判断是否数字
function IsNumeric(txt) {
if (txt == "") {
return false;
}
if (txt.indexOf(",") > 0) {
txt = txt.replace(",", "");
}
if (isNaN(txt)) {
return false;
}
else {
return true;
}
}
将数字进行两位小数的格式化
function changeTwoDecimal_f(x) {
var f_x = parseFloat(x);
if (isNaN(f_x)) {
alert('function:changeTwoDecimal->parameter error');
return false;
}
f_x = Math.round(f_x * 100) / 100;
var s_x = f_x.toString();
var pos_decimal = s_x.indexOf('.');
if (pos_decimal pos_decimal = s_x.length;
s_x += '.';
}
while (s_x.length s_x += '0';
}
return s_x;
}
Js 进行数字运算的函数 parseFloat parseInt
js 当前日期 yyyy-mm-dd 预置查询条件
var now = new Date();
var year = now.getYear();
if (now.getYear() year = now.getYear() + 1900;
}
var month = now.getMonth() + 1;
var day = now.getDate();
if (month if (day
$("#txtDate1").val(year.toString() + "-" + month.toString() + "-01");
$("#txtDate2").val(year.toString() + "-" + month.toString() + "-" + day.toString());
Js 获取时间戳,在某些情景下代替Guid
function NowTimeCode()
{
var Result="";
var now = new Date();
var year = now.getYear();
if (now.getYear() year = now.getYear() + 1900;
}
var month = now.getMonth() + 1;
var day = now.getDate();
var hour = now.getHours();
var minutes = now.getMinutes();
var second = now.getSeconds();
var millisecond = now.getMilliseconds();
if (month if (day if (hour if (minutes if (second
if (millisecond millisecond = "00"+ millisecond;
else
{
if (millisecond {
millisecond = "0"+ millisecond;
}
}
Result = year.toString() + month.toString() + day.toString() + hour.toString() + minutes.toString() + second.toString() + millisecond.toString();
return Result;
}
