Menu
I’m using the following “text sections” script which is great. But I want to add a “previous” button & cannot figure it out. Any help would be great!
this is in my external .js file:
function toggleMe(a){
var next=document.getElementById(a);
var b=new String();
b= a-1;
var prev=document.getElementById(b);
if(!next)return true;
if(next.style.display==”none”){
next.style.display=”block”
prev.style.display=”none”
window.scrollTo(0,0);
} else {
next.style.display=”none”
}
return true;
}
And this goes in the body of the html page:
<div id=”1″ style=”display: block;”>
<p>

<input type=”button” class=”pagebutton button” onclick=”return toggleMe(‘2’)” value=”Go to Section 2″>
</div>
<div id=”2″ style=”display: none;”>

<input type=”button” class=”pagebutton button” onclick=”return toggleMe(‘4’)” value=”Go to Section 4″>
</div>
<div id=”4″ style=”display: none;”>

Ma quande lingues coalesce, li grammatica del resultant lingue es plu simplic e regulari quam ti del coalescent lingues. Li nov lingua franca va esser plu simplic e regulari quam li existent Europan lingues.</p>

<strong>Do not put a button on the last section; your page is done, the user can’t go any farther.</strong><p>

<em>You could always add a button to reload the page:</em></p>
<input type=”button” class=”pagebutton button” onclick=”window.location.reload()” value=”Reload page”>
</div>
