jquery - Changing textContent using javascript, Cushy CMS -

ok, i'm going bad rep here asking many questions. have javascript dynamically changes content on page. works fine. issue need able tag text 'class="cushycms"' in order allow access site owner easy content changes. here basic code script, there more 1 set give idea of i'm doing. tried adding class tag inside innerhtml, cushy couldn't see it.

<script language="javascript" type="text/javascript">    function changetext(idelement) {     if(idelement==0){       document.getelementbyid('tagmain').innerhtml ='<class="cushycms">default text display on page load.';       document.getelementbyid('tagtext').innerhtml ='<class="cushycms">more default body text on page load.';    } </script> 

i looking way put these text fields in hidden div , pull textcontent there. example of section works cushy

 <h2 class="cushycms">preventative maintanence</h2> 

i'm beginning hang of javascript, though java primary language. want more rounded langauge skills trying leanr as can. in advance help.

cushy cms requires actual html in order edit. use following:

html

<p id="tagmain-replace" class="cushycms" style="display:none;"></p> <p id="tagmain">default text</p> 

js

var newtext = document.getelementbyid('tagmain-replace').innertext; if( newtext != ''){     document.getelementbyid('tagmain').innertext = newtext; } 

i suggest changing ids better work project.
