On Click, Change className of Multiple Elements with the Same className

[olylo]

Hi,

Basically, what I am trying to do is this:

<p class="nav_p"><img src="<? nav('Home'); ?>" alt="" /></p>
<p class="nav_p"><img src="<? nav('e-Portfolio'); ?>" alt="" /></p>
<p class="nav_p"><img src="<? nav('Blog'); ?>" alt="" /></p>
<p class="nav_p"><img src="<? nav('About Me'); ?>" alt="" /></p>
<p class="nav_p"><img src="<? nav('Links'); ?>" alt="" /></p>
<br />
<p class="nav_p_small"><img src="<? nav_small('Big'); ?>" alt="" /></p>
<p class="nav_p_small"><a href="#" onclick="[change all elements with the current class of "nav_p" to a class of "nav_p_small"]><img src="<? nav_small('Small'); ?>" alt="" border="0" /></a></p>

onclick="[change all elements with the current class of "nav_p" to a class of "nav_p_small"]

How can I do this? Any help would be very much appreciated.

function swapClass() {
// assumes all elements with class='nav_p'are <p>
var aP=document.getElementsByTagName('p');
for(var i=0; i<aP.length; i++) {
    if(aP[i].className==='nav_p') {
        aP[i].className='nav_p_small';
        }
    }
}

Well, that works for <p> but what if i want to change the class of a DIV? I tried to do it by myself but i'm not familiar with javascript, so.. can u guys give me a light?

This should work, just edited code of Fang.

function swapClass() {
// assumes all elements with class='nav_div'are <div>
var aDiv=document.getElementsByTagName('div');
for(var i=0; i<aDiv.length; i++) {
    if(aDiv[i].className==='nav_div') {
        aDiv[i].className='nav_div_small';
        }
    }
}

    if(aDiv[i].className==='nav_div') {
        aDiv[i].className='nav_div_small';
        }
    }
}

Thanks! This pretty much worked. But i noticed that when i change the class by clicking the div i cant click again to just swap to original class. How can i apply this swap between classes?

		
function changeClass(x)
	{
	    x.className=(x.className=="boxes")?"boxes-min":(x.className=="boxes-min")?"boxes":"boxes-min";
	}
