Read Multiple lines of Text field value using JQuery

To read a value of multiple lines of text from a Edit Form or New Form. Assume Comments is the field name

<script  language="javascript" type="text/javascript" >
function PreSaveAction()
   var Comments = getTagFromIdentifierAndTitle("textarea","TextField","Comments");  

   var CommentsText = RTE_GetEditorDocument(;
   var CommentsTextValue = CommentsText .body.innerText;

function getTagFromIdentifierAndTitle(tagName, identifier, title) 
    var len = identifier.length;  
    var tags = document.getElementsByTagName(tagName);  
    for (var i=0; i < tags.length; i++)
        var tempString = tags[i].id;  
        if (tags[i].title == title && (identifier == "" || tempString.indexOf(identifier) == tempString.length - len))
            return tags[i];  
    return null;  


Additionally, use the following code to read the selected value of a drop down.

var val =  $("select[title='ChoiceFieldName']").val();

  1. Thanks! It looks this is the newest one on 'get value from multiple lines of text'. I tried this code but returned 'null' value from function call. Do you have idea what's wrong?
