javascript - How to toggle element visibility without jQuery? -

-

i'm writing auction template ebay, hoping ebay allow it. apparently don't because jquery has things string.replace() etc.

the code basic.

$(document).ready(function(){      function changeimage(){         if($("#coin1").css("display") == "none"){               $("#coin1").fadein("slow");         }else{               $("#coin1").fadeout("slow");         }     };      setinterval ( changeimage, 5000 ); });

i need rewrite in plain javascript...

if can live without fading effect, should pretty straightforward:

function changeimage() {     var image = document.getelementbyid('coin1');     image.style.display = (image.style.display == 'none') ? 'block' : 'none'; }  setinterval(changeimage, 5000);

while fading cool , all, it's makes code lot more complicated, when not allowed use external libraries. basically, need deal additional timers, firing short intervals, changing opacity of target element on each callback.

if want fading, see "javascript tutorial - simple fade animation".
