Making fields hidden should quite frankly be a built in feature of SharePoint. Here are two interesting tricks I found to modify the NewForm.aspx and EditForm.aspx pages, without opening up SharePoint Desinger.
1) Append this to the URL string. This will force the page edit option. &ToolPaneView=2
2) Add a Content Editor Web Part to the page.
3) Paste this javascript code into the web part.
<script language="javascript" type="text/javascript">
_spBodyOnLoadFunctionNames.push("hideFields");
function findacontrol(FieldName) {
var arr = document.getElementsByTagName("!");
// get all comments
for (var i=0;i < arr.length; i++ )
{
// now match the field name
if (arr[i].innerHTML.indexOf(FieldName) > 0)
{ return arr[i]; }
}
}
function hideFields() {
var control = findacontrol("Title");
control.parentNode.parentNode.style.display="none";
}
</script>
