Creating function to expand/close all nodes

**natanz** · 09-14-2012 01:39 AM

Hey guys,

I got these codes:

JS:

Code:

<script language="JavaScript" type="text/javascript">
function openClose(theID) {
if (document.getElementById(theID).style.display == "block") { document.getElementById(theID).style.display = "none" }
else { document.getElementById(theID).style.display = "block" } }
</script>

CSS:

Code:

.texter {display:none} @media print {.texter {display:block;}}

HTML:

Code:

<a class= "link_item" href="#" onclick="openClose('a2'); return false;">Link</a><br/>
<br/><br/>
<div id="a2" class="texter">BLA BLA BLA</div>

I want to create an "Open/Close all" function.
All my tries have not succeeded.

Please help me.

Regards!

1. Thank you for helping.

2. Sorry,
But I think you got me wrong.

My goal is to add a function (to the current expand/close specific).

Or I got you wrong... - You did not post HTML code neither.

Regards.

In jquery, there's a function called toggle() that will help.

<script language="JavaScript" type="text/javascript">
function openCloseAll(){
$('a').toggle();
}
</script>

of course, this supposes that all tags are visible or all tags are closed.
If one must remain open or closed when you call the function, change it in this way:

<script language="JavaScript" type="text/javascript">
function openCloseAll(){
$('a').toggle();
$(this).toggle();
}
</script>

<a href="#" onclick="openCloseAll()">abc</a>

adding a class let's you filter the target anchors...

<script language="JavaScript" type="text/javascript">
function openCloseAll(){
$('a.openclose').toggle();
$(this).toggle();
}
</script>

<a href="#" onclick="openCloseAll()" class="openclose">abc</a>

Hey,
I've tried the function but it hides most parts of my webpage

It's only a question of choosing the right selector.
Adding classes helps to filter your selection.
http://api.jquery.com/category/selectors/

methods hide(), show(), toggle(), fadeIn(), fadeOut(), addClass(), removeClass() and css() will be the most usefull to play on the visibility of your elements.

I hope this will be of some help
