Javascript onclick link text change

Question

I'm working on a new page and for the mobile version I'm going to make a navigation toggle in order to hide and to show the navigation.

HTML code :

<div id="toogleNavigation">
    <a onclick="toggle_visibility('nav_header','nav_header_level2');">Navigation Einblenden</a>
</div>

Javascript code :

function toggle_visibility(id, id2) {
    var e = document.getElementById(id);
    var f = document.getElementById(id2);
    if(e.style.display == 'block' || 
       e.style.display == 'block' && 
       f.style.display == 'block') {
        e.style.display = 'none';
        f.style.display = 'none';
        document.getElementById('toogleNavigation').innerHTML = "Navigation 1einblenden";
    } else {
        e.style.display = 'block';
        f.style.display = 'block';
        document.getElementById('toogleNavigation').innerHTML = "Navigation 2ausblenden";
    }
}

I've tried with :

document.getElementById('toogleNavigation').innerHTML = "Navigation 2ausblenden";

to change the text in text "Navigation Einblenden" when pressing on the link, but this doesn't work... Does somebody has an idea?

Answer 1

Moved the id from div to the a.

See it working in jsbin http://jsbin.com/eqeheb/5/watch

<div> <a id="toogleNavigation" onclick="toggle_visibility('nav_header','nav_header_level2');">Navigation Einblenden</a> </div>

Answer 2

Make change like this....
HTML code

<div id="toogleNavigation">
    <a id="divInner" onclick="toggle_visibility('nav_header','nav_header_level2');">
        Navigation Einblenden
    </a>
</div>

And JavaScript Code

function toggle_visibility(id, id2) {
   var e = document.getElementById(id);
   var f = document.getElementById(id2);
   if(e.style.display == 'block' ||
      ( e.style.display == 'block' &&            
      f.style.display == 'block' ) ) {
        e.style.display = 'none';
        f.style.display = 'none';
        document.getElementById('divInner').innerHTML = "Navigation  1einblenden";
      } 
      else {
        e.style.display = 'block';
        f.style.display = 'block';
        document.getElementById('divInner').innerHTML = "Navigation 2ausblenden";
      }
}
