Js獲取頁面地址參數
復制代碼 代碼如下:
function getUrlPara(paraName)
{
var sUrl = location.href;
var sReg = "(?://?|&){1}" + paraName + "=([^&]*)"
var re = new RegExp(sReg, "gi");
re.exec(sUrl);
return RegExp.$1;
}

地址跳轉
復制代碼 代碼如下:
var pn = $("#gotopagenum").val();//#gotopagenum是文本框的id屬性
location.href = "NewList.aspx?pagenum="+pn;//location.href實現客戶端頁面的跳轉

千分位
復制代碼 代碼如下:
function Convert(money)
{
var s = money; //獲取小數型數據
s += "";
if (s.indexOf(".") == -1) s += ".00"; //如果沒有小數點，在後面補個小數點和00
if (/\.\d$/.test(s)) s += "0"; //正則判斷
while (/\d{4}(\.|,)/.test(s)) //符合條件則進行替換
s = s.replace(/(\d)(\d{3}(\.|,))/, "$1,$2"); //每隔3位添加一個
return s;
}

判斷是否數字
復制代碼 代碼如下:
function IsNumeric(txt) {
if (txt == "") {
return false;
}

if (txt.indexOf(",") > 0) {
txt = txt.replace(",", "");
}

if (isNaN(txt)) {
return false;
}
else {
return true;
}
}

將數字進行兩位小數的格式化
復制代碼 代碼如下:
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 < 0) {
pos_decimal = s_x.length;
s_x += '.';
}
while (s_x.length <= pos_decimal + 2) {
s_x += '0';
}
return s_x;
}

Js 進行數字運算的函數 parseFloat parseInt

js 當前日期 yyyy-mm-dd 預置查詢條件
復制代碼 代碼如下:
var now = new Date();
var year = now.getYear();

if (now.getYear() < 1900) {
year = now.getYear() + 1900;
}

var month = now.getMonth() + 1;
var day = now.getDate();

if (month < 10) month = "0" + month;
if (day < 10) day = "0" + day;

$("#txtDate1").val(year.toString() + "-" + month.toString() + "-01");
$("#txtDate2").val(year.toString() + "-" + month.toString() + "-" + day.toString());

Js 獲取時間戳，在某些情景下代替Guid
復制代碼 代碼如下:
function NowTimeCode()
{
var Result="";

var now = new Date();

var year = now.getYear();

if (now.getYear() < 1900) {
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 < 10) month = "0" + month;
if (day < 10) day = "0"+ day;
if (hour < 10) hour = "0"+ hour;
if (minutes < 10) minutes = "0"+ minutes;
if (second < 10) second = "0"+ second;

if (millisecond < 10)
millisecond = "00"+ millisecond;
else
{
if (millisecond < 100)
{
millisecond = "0"+ millisecond;
}
}

Result = year.toString() + month.toString() + day.toString() + hour.toString() + minutes.toString() + second.toString() + millisecond.toString();

return Result;

}
