Jquery Input Number Validation

$(document).ready(function() {
    $("#txtboxToFilter").keydown(function(event) {
        // Allow: backspace, delete, tab, escape, and enter
        if ( event.keyCode == 46 || event.keyCode == 8 || event.keyCode == 9 || event.keyCode == 27 || event.keyCode == 13 || 
             // Allow: Ctrl+A
            (event.keyCode == 65 && event.ctrlKey === true) || 
             // Allow: home, end, left, right
            (event.keyCode >= 35 && event.keyCode <= 39)) {
                 // let it happen, don't do anything
                 return;
        }
        else {
            // Ensure that it is a number and stop the keypress
            if (event.shiftKey || (event.keyCode < 48 || event.keyCode > 57) && (event.keyCode < 96 || event.keyCode > 105 )) {
                event.preventDefault(); 
            }   
        }
    });
});

For number only

Greasemonkey and JQuery

I try to @require http://ajax.microsoft.com/ajax/jQuery/jquery-1.4.2.js
but it fail

so after search found if use full version (min version will get another error.)
we must change some in jquery code in line by used try catch to avoid error

isSupported = (eventName in el);
if ( !isSupported ) {
el.setAttribute(eventName, "return;");
isSupported = typeof el[eventName] === "function";
}
el = null;

to

try {
isSupported = (eventName in el);
if ( !isSupported ) {
el.setAttribute(eventName, "return;");
isSupported = typeof el[eventName] === "function";
}
el = null;
} catch(e) {}

now it work.

and another notice require will load only once when install user script to grease monkey so if you edit it it will need to uninstall and install again

to install new script is easy drag and drop your script to browser.

and you got lasted script by

jQuery and error "$ is not define"

To day I use Jquery in ASP.NET MVC and can't make it work.
It's always show java script error about "$ is not defined"

Yes after search and found a call wrong path for Include my jQuery script

and my problem now is confuse about relative path for jquery in my master page

and finally anything solve by

Url.Content ("~/Scripts/jquery-1.3.2.min.js")

Used this instead of

../../Scripts/jquery-1.3.2.min.js

Yes I don't include full code here because Google don't support code html for example with out encoding it myself.

I will find another block for do that.

Yes this will solve problem with css too.
