Javascript functions work in firefox and chrome but not IE9

[nerone]

I have some simple functions in javascript which work fine in most browser except IE9. I have heard Ie9 is fussy about commas etc. But I cannot spot any obvious problems. Can anyone of you guys and gals shed any light? Full code below\[code\] <script type="text/javascript"> document.addEventListener("DOMContentLoaded", load, false); function load() { //dom loaded var elUserId = document.getElementById("user_id"); var elPasswordId = document.getElementById("password"); var elLoginMsg = document.getElementById("usernameMsg"); var elPasswordMsg = document.getElementById("passwordMsg"); var elIncreaseFontSize = document.getElementById("increaseFont"); var elResetFontSize = document.getElementById("resetFont"); var elChangeContrast = document.getElementById("changeContrast"); var elResetContrast = document.getElementById("resetContrast"); var logInbox = document.getElementById("loginBox"); var helpWithBB = document.getElementById("helpWithBB"); var fontUp = '135%'; var fontReset = '100%'; var black = '#000000'; var white = '#ffffff'; var divReset ='415px'; var divChange ='525px'; var txtSizeChange ='40.5em'; var txtReset ='42em'; elLoginMsg.style.display ='none'; elPasswordMsg.style.display = 'none'; elPasswordId.addEventListener("focus", function(){ showText(elPasswordMsg); }, false); elUserId.addEventListener("click", function(){ showText(elLoginMsg); }, false); elResetFontSize.addEventListener("click", function(){ //pass size change and element affected to be manipulated //resetTextSize(fontReset,logInbox,elPasswordMsg); changeTextSize(fontReset,logInbox,elPasswordMsg,divReset,txtReset); }); elChangeContrast.addEventListener("click", function(){ //pass size change and element affected to be manipulated changeContrast(logInbox, helpWithBB, black, white); }); elResetContrast.addEventListener("click", function(){ document.location.reload(true); }); elIncreaseFontSize.addEventListener("click", function(){ //pass size change and element affected to be manipulated changeTextSize(fontUp,logInbox,elPasswordMsg,divChange,txtSizeChange); }); function changeContrast(mainDiv, secDiv, txtColor, bkColor){ secDiv.style.background = bkColor; mainDiv.style.background = bkColor; showText(elPasswordMsg); showText(elLoginMsg); elLoginMsg.style.color = txtColor; elPasswordMsg.style.color = txtColor; var anchors = document.getElementsByTagName('a'); for(var i = 0; i < anchors.length; i++) { anchors.style.color = txtColor; } var para = document.getElementsByTagName('p'); for(var i = 0; i < anchors.length; i++) { para.style.color = txtColor; } } function changeTextSize(fontUp, elDiv, msg, divH, msgT){ document.body.style.fontSize=fontUp; elDiv.style.height = divH; msg.style.top = msgT; } function showText(id){ id.style.display ='block'; } } </script> \[/code\]
