myElement.style.displays = 'hide';

**rfl** · Jan 24, 2007, 12:57

i'm playing around with javascript and tried the following:
//a.js

HTML Code:

function  oculta() {
    var paragrafo = document.getElementById("a");
    paragrafo.style.displays = 'hide';
}
window.onload = oculta;

//test.htm

HTML Code:

<html>
<head>
<title></title>
<style type = "text/css"></style>
<script type = "text/javascript" src = "a.js"></script>
</head>
<body>
<p id = "a" >bla bla</p>
</body>
</html>

but nothing happens, either i use 'none', or '' or even 'hide'
what am i doing wrong?

should be:

Code:

paragrafo.style.display = 'none';

display not displays

that's how i had it, but allways got a error msg saying invalid argument about display property;
so i went here:

and changed it...

shoudn't it be

Code:

window.onload = oculta();

instead of

Code:

window.onload = oculta;

?

just a thought...

Only if you want the oculta() function to run immediately and return the value that is to be run when the page finishes loading. If you want oculta to run after the page is loaded you need to leave off the () so that it assigns the function to the event handler and not the value returned from the function.

This code works fine for me, there must be something else in your script:

HTML Code:

<html>
<head>
<title></title>
<style type = "text/css"></style>
<script type = "text/javascript"><!--
function  oculta() {
    var paragrafo = document.getElementById("a");
    paragrafo.style.display = "none";
}
window.onload = oculta;
//-->
</script>
</head>
<body>
	<p id="a">bla bla</p>
</body>
</html>

Thank you Felgall for explaining a problem I've had for ages. I was always getting those 'property not etc...' errors when I used window.onload, and now I understand why.

cant use hide, but none or '' instead, and so works fine
