Please help me to adjust an existing script to replace COMMA with DOT. I use a script which limit the inserting character into Text fields. Only 1,2,3,4,5,6,7,8,9,0 and "." and "," are accepted to be inserted. I would like to have two buttons of inserting DOT - key==188 (ma) and key== 190 (dot).

jQuery.fn.ForceNumericOnly =
    function()
    {
        return this.each(function()
        {
            $(this).keydown(function(e)
            {
                var key = e.charCode || e.keyCode || 0;
                return (
                    key == 8 || 
                    key == 9 ||
                    key == 46 ||
                    key == 110 ||
                    key == 188 ||   
                    key == 190 ||
                    (key >= 35 && key <= 40) ||
                    (key >= 48 && key <= 57) ||
                    (key >= 96 && key <= 105));

            });
        });
    };
$("#iMONEY").ForceNumericOnly();

• It is not clear what problem you're having. – Pointy Commented Oct 20, 2013 at 7:36
• I do not know how to replace COMMA with DOT... – Sergiu Costas Commented Oct 20, 2013 at 7:37
• It is easy to give up from COMMA, but I would like to have ACTIVE button COMMA but inserting DOT – Sergiu Costas Commented Oct 20, 2013 at 7:38
• 1 I think it'd be easier to catch "keypress" and simply replace any mas in the field value with dots. – Pointy Commented Oct 20, 2013 at 7:40
• I honestly would avoid such approach, unless it's okay to you don't replace ma with dot if the user paste a text with ma in the text field (using keyboard or mouse). Same it's applying for drag & drop. – ZER0 Commented Oct 20, 2013 at 8:33

Just use

if(e.keyCode == 188){
    e.preventDefault();
    $(this).val($(this).val() + '.');
}

Here you go. :)

For future references Mini-Tutorial.

The value of the textbox is updated after keypress event is fired. It's not a place to replace ma with dot. Use keyup event instead:

jQuery.fn.ForceNumericOnly =
    function()
    {
       this.keyup(function(e)
            {
//                console.log("Change");
                $(this).val($(this).val().replace(/,/g,"."));
            });
    };
$("#iMONEY").ForceNumericOnly();

DEMO

var key = e.charCode || e.keyCode || 0;
// 110 is numpad ma code
if (key === 188 && key === 110) {
    e.preventDefault();
    $(this).val($(this).val() + '.');                   
}

You need to use the Replace method

var someVariable = "1,2,3,4,5,6,7,8,9,0";
$mylabel.text( someVariable.replace(',', '.') );

EDIT: If you are checking from TextBox then do it like this:

if(Key == 188){
   var someVariable =  $("#TEXTBOXID").val();
    somVariable = someVariable.replace(',', '.');
}
