jQuery getTime function

问题

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...

回答1:

@nickf's correct. However, to be a little more precise:

// 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:

var displayDate = (myDate.getMonth()+1) + '/' + (myDate.getDate()) + '/' + myDate.getFullYear();

Check out the full reference of 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-functions available in the wild.

回答2:

Yes, it is possible:

jQuery.now()

or simply

$.now()

see jQuery Documentation for jQuery.now()

You don't need jquery to do that, just javascript. For example, you can do a timer using this:

<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>

It's plain javascript:

new Date()

this is my way :

    <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 :)

回答7:

Annoyingly Javascript's date.getSeconds() et al will not pad the result with zeros 11:0:0 instead of 11:00:00.

So I like to use

date.toLocaleTimestring()

Which renders 11:00:00 AM. Just beware when using the extra options, some browsers don't support them (Safari)
