Replace Point keystroke with a Comma

Sometimes you need to prevent your user to use some key characters in your Input Fields.
Like my customer wanted also to use the Comma [,] as the Point [.] as decimal seperator. 
If you use for example Dutch regional settings the decimal seperator is the [,] and the Point is used
as thousant seperator. So my customer wanted to use as Point as Comma as seperator. 
What to do about it? 
Simple answer. Catch the keystroke of the Point and replace it by a Comma. 
My solution below is not perfect if they put a Point between the numbers. 
If someone knows what I have to add in place of the fill up of the ","
please don't hesitate to let me know.
 

$(document).ready(function() {
 if ($(":input[title='MyField']").val() != "")
  $("nobr:contains('MyField')").closest('tr').hide();
 ReplacePointbyComma();
});

function ReplacePointbyComma(){
    $(":input[title='MyNumericField']").keydown(function(e) {
  var keycode = (e.keyCode ? e.keyCode : e.which);
  /// 110 Point on numeric keyblock
  /// 190 Shift Point in alfanumeric keyblock
  if (keycode == 110 || keycode == 190 )
  {
   e.preventDefault();
   $(":input[title='MyNumericField']").val($(":input[title='MyNumericField']").val() + ",");
  }
 });
}
 

Check if Sharepoint Richt Text Editor Field is empty or not (works in IE, Firefox and Chrome)

Found out this week that the code for checking the content of a multi-line rich text field was 
not working for other than IE-browsers.
So after some debugging in Chrome I found a solution that works in Chrome and in Firefox.
I hope that it's also working in other browsers... but I don't have them to my position at work.
Have fun with my new code... 

 firefox/chrome bugfix...
    var scomments = "";
    if ($.browser.msie) 
 {     
  // IE browser, check on language needed because Sharepoint and IE Translates the IFrame name in different languages.   
  if (_spPageContextInfo.currentLanguage == 1036) 
  {
            var systemDescriptionRTE = $("textarea[title='Comments']").closest("span").find("iframe[Title='Éditeur de texte enrichi']").contents().find("body");
            scomments = $(systemDescriptionRTE).text();
        }
        else
        {
            if (_spPageContextInfo.currentLanguage == 1043) 
   {
                var systemDescriptionRTE = $("textarea[title='Comments']").closest("span").find("iframe[Title='RTF-editor']").contents().find("body");
                scomments = $(systemDescriptionRTE).text();
            }
            else
            {
                var systemDescriptionRTE = $("textarea[title='Comments']").closest("span").find("iframe[Title='Rich Text Editor']").contents().find("body");
                scomments = $(systemDescriptionRTE).text();
            }
        }
 }
 else
 {
 // if other browser
        var systemDescriptionRTETextArea = $("textarea[Title='Comments']"); 
        scomments = $(systemDescriptionRTETextArea).val(); 
 }
  

Now you can check with the 'scomments' variable is it is empty or containing some values.

Check if Rich TextField is Empty

Last week I had some problems to do a check wether a Rich Text Box is filled in or not. 
When doing a check on the Text propertie of the TextField, 
I found out that Sharepoint puts default something in the TextField. 

Like it or not, but it's really frustrating that you can't use the JQuery test .isEmpty().
So after some testing, I found out that Sharepoint puts a Paragraph tag in the TextField. 
So here under you can found out how I did the check wether a Rich TextField is filled in or not. 
 

if( ($(ctl00_m_g_6e043a15_d2d5_4e91_a8c6_562e51fe3b46_ff121_ctl00_ctl00_TextField_inplacerte).text() == "") || ($(ctl00_m_g_6e043a15_d2d5_4e91_a8c6_562e51fe3b46_ff121_ctl00_ctl00_TextField_inplacerte).html() == "
?
") )
    {
        alert('Please fill in the Rich Text box field !');
        return false;
    }
