jQuery getTime function
提问by Tsundoku
is it possible to create a jQuery function so that it gets current date and time? I've been looking around documentation but haven't found anything so far...
是否可以创建一个 jQuery 函数来获取当前日期和时间？我一直在寻找文档，但到目前为止还没有找到任何东西......

@nickf's correct. However, to be a little more precise:
@nickf 是对的。但是，更准确地说：
// if you try to print it, it will return something like:
// Sat Mar 21 2009 20:13:07 GMT-0400 (Eastern Daylight Time)
// This time comes from the user's machine.
var myDate = new Date();
So if you want to display it as mm/dd/yyyy, you would do this:
所以如果你想把它显示为 mm/dd/yyyy，你可以这样做：
var displayDate = (myDate.getMonth()+1) + '/' + (myDate.getDate()) + '/' + myDate.getFullYear();
Check out the full referenceof the Date object. Unfortunately it is not nearly as nice to print out various formats as it is with other server-side languages. For this reason there-are-many-functionsavailable in the wild.
查看Date 对象的完整参考。不幸的是，打印出各种格式并不像使用其他服务器端语言那样好。出于这个原因有-有-多-功能在野外可用。

You don't need jquery to do that, just javascript. For example, you can do a timer using this:
你不需要 jquery 来做到这一点，只需要 javascript。例如，您可以使用以下方法执行计时器：
<body onload="clock();">
<script type="text/javascript">
function clock() {
var now = new Date();
var outStr = now.getHours()+':'+now.getMinutes()+':'+now.getSeconds();
document.getElementById('clockDiv').innerHTML=outStr;
setTimeout('clock()',1000);
}
clock();
</script>
<div id="clockDiv"></div>
</body>

this is my way :
这是我的方式 ：
<script type="text/javascript">
$(document).ready(function() {
setInterval(function(){currentTime("#idTimeField")}, 500);
});
function currentTime(field) {
var now = new Date();
now = now.getHours() + ':' + now.getMinutes() + ':' + now.getSeconds();
$(field).val(now);
}
it's not maybe the best but do the work :)
这可能不是最好的，但要做好工作:)

Annoyingly Javascript's date.getSeconds()et alwill not pad the result with zeros 11:0:0instead of 11:00:00.
令人讨厌的是，Javascriptdate.getSeconds()等人不会用零11:0:0代替11:00:00.
So I like to use
所以我喜欢用
date.toLocaleTimestring()
Which renders 11:00:00 AM. Just beware when using the extra options, some browsers don't support them (Safari)
其中呈现11:00:00 AM. 使用额外选项时请注意，某些浏览器不支持它们（Safari）
