<body>
获取和设置input的值：<input type='hidden' id='provSelect1' name='provSelect1' runat='server' value='111' />
<script>
window.onload = function(){
var psel = document.getElementById("provSelect1");
alert("获取到的value：" + psel.value+" ,"+$("#provSelect1").val()); //获取
psel.value = "123"; //设置
alert("设置后的value：" + psel.value); //设置后的
};
$(document).ready(function(){
var val = $("#provSelect1").val(); //获取
alert("获取到的value：" + val);
$("#provSelect1").val("123"); //设置
alert("设置后的value：" + $("#provSelect1").val());
});
</script>
</body>
实际运用（reset属性的另一种写法）
<script>
function getNowDate() {
var date = new Date();
var sign1 = "-";
var sign2 = ":";
var year = date.getFullYear() // 年
var month = date.getMonth() + 1; // 月
var day = date.getDate(); // 日
var hour = date.getHours(); // 时
var minutes = date.getMinutes(); // 分
var seconds = date.getSeconds() //秒
// 给一位数数据前面加 “0”
if (month >= 1 && month <= 9) {
month = "0" + month;
}
if (day >= 0 && day <= 9) {
day = "0" + day;
}
var currentdate = year + sign1 + month + sign1 + day;
return currentdate;
}
//console.log(getNowDate());
function res() {
var username = document.getElementById("username");
var rechargeId = document.getElementById("rechargeId");
var fromTime = document.getElementById("fromTime");
var toTime = document.getElementById("toTime");
var type = document.getElementById("type");
username.value='用户名';
rechargeId.value='充值编号';
fromTime.value=getNowDate()+"T00:00";
//console.log(time1);
toTime.value=getNowDate()+"T23:59";
type.value='';
}
</script>
