Jquery tutorials limit text boxes to Numbers and decimal point examples to share

$(function(){    
             
            $(".NumText").keyup(function(){   
                    $(this).val($(this).val().replace(/D|^0/g,'')); 
                }).bind("paste",function(){  //CTR+V event handling & NBSP;    
                    $(this).val($(this).val().replace(/D|^0/g,''));    
                }).css("ime-mode", "disabled"); //CSS Settings input method not available & NBSP;    

             
            $(".NumDecText").keyup(function(){   
                    $(this).val($(this).val().replace(/[^0-9.]/g,''));   
                }).bind("paste",function(){  //CTR+V event handling & NBSP;    
                    $(this).val($(this).val().replace(/[^0-9.]/g,''));    
                }).css("ime-mode", "disabled"); //CSS Settings input method not available & NBSP;    
        }); 

Then add the class name to the text box that needs to be validated, like this:

<input type="text" class="txt NumText"  Width="100px"  runat="server" />
