unable to edit css with javascript -


i trying edit form these simple

testings:

<span id="a">30 <span id="aa" style="display:none;"><input type="text" id="aa" name="q"/></span></span> <span id="cq"><a href="javascript:changeqty()">change</a></span> <span id="cq2" style="display:none"><a href="javascript:save()">save</a></span>  <script>   function changeqty(){     document.getelementbyid("a").style.display="hidden";     document.getelementbyid("aa").style.display="inline";     document.getelementbyid("cq").style.display="hidden";     document.getelementbyid("cq2").style.display="inline";   } </script>

but strangely,my attempt hide fields not working. can view hidden fields when click on change link. whats wrong doing ?

there no hidden attribute display, need use none.

function changeqty(){   document.getelementbyid("a").style.display="none";   document.getelementbyid("aa").style.display="inline";   document.getelementbyid("cq").style.display="none";   document.getelementbyid("cq2").style.display="inline"; }
