我正在使用html5输入类型:日期和时间。如何将表单输入类型转换为javascript对象日期(其中包括时间)?
这是我的一部分代码:
<html>
<head>
<script type="text/javascript">
function getDate(date, time)
{
var theDate = new Date();
....
}
</script>
</head>
<body>
<form name="form_task">
Date:<input type="date" name="task_date" />
Time:<input type="time" name="task_time" />
<input type="button" onclick="getDate(task_date.value, task_time.value)" />
</form>
</body>
</html>
您所需要做的就是从两个输入中提取值，将它们连接起来，然后将它们传递给日期对象。

HTML
Date:<input id="date" type="date" name="task_date" />
Time:<input id="time" type="time" name="task_time" />
<button id="calc">Get Time</button>
JS
var calc = document.getElementById("calc")
calc.addEventListener("click", function() {
var date = document.getElementById("date").value,
time = document.getElementById("time").value
console.log(new Date(date + " " + time))
})
你可以这样做:
<!DOCTYPE html>
<style type="text/css">
label {
width:150px;
display:inline-block;
}
</style>
<label for="admissionDate">admission date</label>
<input id="admissionDate" name="admissionDate" type="date" />
<br />
<label for="graduationDate">graduation date</label>
<input id="graduationDate" name="graduationDate" type="date" />
<br />
<label for="birthDate" >birth date</label>
<input id="birthDate" type="date" name="birthDate" />
<br />
<button id="age">Get Age</button>
<script type="text/javascript">
var doc = document;
var admission = doc.getElementById("admissionDate");
var graduation = doc.getElementById("graduationDate");
var birth = doc.getElementById("birthDate");
var age = doc.getElementById("age");
age.addEventListener("click", function(){
var gradDate = new Date(graduation.value);
var birthDate = new Date(birth.value);
var dateDiff = new Date(gradDate - birthDate);
var YEAR_OFFSET = 1970;
alert("This person is " + (dateDiff.getFullYear()-YEAR_OFFSET) + " years old");
});
</script>
**我是这样做的**
var calc = document.getElementById("calc")
calc.addEventListener("click", function() {
var date = document.getElementById("date").value,
time = document.getElementById("time").value
var hi = new Date(date + " " + time).toISOString();
// Set the date we're counting down to
var countDownDate = new Date(hi).getTime();
// Update the count down every 1 second
var x = setInterval(function() {
// Get today's date and time
var now = new Date().getTime();
// Find the distance between now and the count down date
var distance = countDownDate - now;
// Time calculations for days, hours, minutes and seconds
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance % (1000 * 60)) / 1000);
// Output the result in an element with id="demo"
document.getElementById("demo").innerHTML = days + "d " + hours + "h "
+ minutes + "m " + seconds + "s ";
// If the count down is over, write some text
if (distance < 0) {
clearInterval(x);
document.getElementById("demo").innerHTML = "وقت المهمة حان ";
}
}, 1000);})<p id="demo"></p>
Date:<input id="date" type="date" name="task_date" />
Time:<input id="time" type="time" name="task_time" />
<button id="calc">Get Time</button>
</div>这样就不会出现date字段中出现日期而date对象有不同日期的问题了。
let datainicio = $("#data-inicio").val();
let datafim = $("#data-fim").val();
if (!datainicio || !datafim) {
bootbox.alert(DATA_INICIO_DATA_FIM_VAZIAS);
return;
}
// the month is 0-indexed
let dateinicio = new Date(datainicio.slice(0, 4), Number(datainicio.slice(5, 7)) - 1, datainicio.slice(8, 10));
let datefim = new Date(datafim.slice(0, 4), Number(datafim.slice(5, 7)) - 1, datafim.slice(8, 10));
console.log("Date(datainicio): " + dateinicio);
console.log("Date(datafim) : " + datefim);
试试这个
<!DOCTYPE html>
<html>
<head>
<script>
function startTime() {
var today=new Date();
var h=today.getHours();
var m=today.getMinutes();
var s=today.getSeconds();
m = checkTime(m);
s = checkTime(s);
document.getElementById('txt').innerHTML = h+":"+m+":"+s;
var t = setTimeout(function(){startTime()},500);
}
function checkTime(i) {
if (i<10) {i = "0" + i}; // add zero in front of numbers < 10
return i;
}
</script>
</head>
<body onload="startTime()">
<div id="txt"></div>
</body>
</html>
