HTML how do I insert dynamic date in webpage

I have a static webpage, nothing changes dynamically. However the client wants a date insert into text within the page. The date will always be the current daet plus one day. how do I 开发者_运维百科do that?

Use JavaScript and insert the date onLoad.

Take a look here for a working example: http://jsfiddle.net/xGDvp/

This will update the date as follows: February 5, 2011

Your HTML:

<span id="spanDate"></span>

Your Javascript

    <script type="text/javascript">
           var months = ['January','February','March','April','May','June','July',
'August','September','October','November','December'];       
var tomorrow = new Date();
tomorrow.setTime(tomorrow.getTime() + (1000*3600*24));       
document.getElementById("spanDate").innerHTML = months[tomorrow.getMonth()] + " " + tomorrow.getDate()+ ", " + tomorrow.getFullYear();
    </script>

You could use Server Side Includes (SSI), if your server supports them.

If your server is Apache, you could, for example, put the following element into your HTML page to output a current date + 1 day:

<pre>
<!--#exec cmd="date -v +1d '+DATE: %Y-%m-%d'" -->
</pre>

Assuming today is 2011-02-05, you'll have the following output on your page in browser:

...
DATE: 2011-02-06
...

To output the full weekday name, you can use date -v +1d '+DATE: %A %d, %Y', which gives you DATE: Sunday 06, 2011.

window.onload = initDate;
function initDate() {
     var dayName = new Array("Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday","Saturday");
     var monName = new Array("January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December");
     var now = new Date();
     var dtString = dayName[now.getDay()] + ", " + monName[now.getMonth()] + " " + now.getDate();
     document.getElementById("dtField"). innerHTML = dtString;
}

If your not opposed to PHP, then you could do something like this... Also Tizag.. http://www.tizag.com/phpT/phpdate.php

<?php
$todayPlusADay = mktime(0, 0, 0, date("m"), date("d")+1, date("y"));
echo "Todays Date Plus One Day (Tomorrow) ".date("m/d/y", $todayPlusADay); 
?>

Quick search for "php echo date + 1 day" produced that little diddy :) That could certainly be expanded upon to any extent just about.

You could use javascript to insert the date somewhere in the page:

<script type="text/javascript">
var newDate = new Date();
newDate.setDate(newDate.getDate() + 1);

//insert it via jquery
$('#displayDate').html((newDate.getMonth() + 1) + '/' + newDate.getDate() + '/' + newDate.getFullYear());

//or insert it via javascript
document.getElementById('displayDate').innerHTML = (newDate.getMonth() + 1) + '/' + newDate.getDate() + '/' + newDate.getFullYear();

</script>

and the html:

<span id="displayDate"></span>

test it here: http://jsfiddle.net/9xWUT/

I recommend XDate because it will save a lot of typing. Also, please don't use innerHTML, it's such a bad habit. I just did the same on a web page and the key thing was to use inline javascript beneath the tag you are updating although you can use 'onload' as well.

In the page I add the tag and put in some default info just because:

<p>Today is <span id="todays_date" style="font-style: italic;">November 1, 2015</span></p>

With this below that:

<script type="text/javascript">
  var today = new XDate();

  document.getElementById("todays_date").innerHTML = "";

  document.getElementById("todays_date").appendChild(document.createTextNode(today.toString("MMMM d, yyyy")));
</script>

NB: I do use innerHTML to quickly obliterate nested tags rather than a recursive "delete all children" because that's in a different library and not pertinent to this example.

You can do that in javascript. http://www.tizag.com/javascriptT/javascriptdate.php

Then you can add for example a span tag in your text, and insert the date with javascript. If you can use jQuery, you can do something like:

html:

<p>Tomorrow: <span class="tomorrow"></span></p>

javascript:

$(function() {
    var date = new Date()
    $(".tomorrow").html(date.getDate() + 1) // you'll have to search how to format the date
});

You can do it in my way this is below

HTML:

< asp:Label ID="Label1" runat="server" Text='' >

JavaScript:

<script language="javascript" type="text/javascript">
function date_time() {
    var dt = new Date();
    document.getElementById('<%=Label1.ClientID%>').innerHTML = dt;
    setTimeout(function () { date_time(); }, 1000);
}
date_time();
