Question

<script type="text/javascript">
//window.onload = Now;
function Now(){
var n=new Date();
return n.toLocaleDateString();

};


</script>

i put the above code in the head part.

<body onload="Now();">

but on the page, there is no show anything.when i using window.onload = Now or put the script code after the label; the result is the same, why?

ps:i want to write the result out on the page. but when i used document.write(Now()); it still not displayed on the page.

The `Now` function doesn't do anything, except return a value. What are you expecting to see? — James Allardice, Jun 25 '13 at 09:53
What result? What do you expect this code to do? As far as I can see it works out what the time is then throws away the result. — symcbean, Jun 25 '13 at 09:54

You aren't doing anything with the return value of Now(), so it is being quietly discarded.

Perhaps you want to do something like onload="alert(Now());"

i want to write the result out. but when i used document.write(Now()); it still not work. – stack2013a Jun 25 '13 at 09:57
That's because `document.write` can only be called before the page has loaded. – Niet the Dark Absol Jun 25 '13 at 09:59
if i want to show the result on the page? how do i do? thank you. – stack2013a Jun 25 '13 at 10:00
There are many ways. The most primitive being `document.body.innerHTML = something` – Niet the Dark Absol Jun 25 '13 at 10:01

Try to put alert box. If it exists in the script or not.

Modify your HTML a bit to have a DOM element that will help you post the resut onto your page,

<body onload="Now();">
    <span id="dateHelper"></span>
</body>

And then modify your script to do the following,

function Now(){
    var n=new Date();
    var lds = n.toLocaleDateString();

    document.getElementById("dateHelper").innerHTML = lds;
};
