How to determine the language of keyboard input using JQuery

I have an application that accepts input in two languages (English and Arabic) I'm validating the input textbox , the validation logic is not the same for English and Arabic, so I need to know what is the language the user is typing

all the solutions I came across determined the default language for the system and browser but nothing I found helped me determining the current input language

ok here is the solution that worked for me. Note that in my application I know for sure the input language will be one of two Languages either input is English Or Arabic so here what I did

            var msgText =  entered message text;
            var textLength = msgText.length; // entered message length
            var isEnglish = true;
            for (var index = 0; index <= textLength; index = index + 1) {

                if (msgText.charCodeAt(index) > 160) {
                    //Not English 
                    isEnglish=false;
                    break;
                }
            }

in the previous Example that is what I Needed , if a single character is Arabic the whole text should be validated as Arabic so I added a variable isEnglish = true by default and will only be changed if a character in the string is not English I iterated the characters in the string using the charCodeAt(index) which returns the ISO Latin-1 Character Number . using the table in the this page I was able to decide that the maximum number in this set that represents English chars was 160 and

You can do this using Google's AJAX Language API

var content = "your text";
google.language.detect(content, function(result) {
  if (!result.error) {
    var language = 'unknown';
    for (lang in google.language.Languages) {
      if (google.language.Languages[lang] == result.language) {
        language = lang;
        break;
      }
    }
    // Now use the variable `language`
  }
});

You can use ActiveXObject to send an input key say 'a' and read its unicode/ascii value. If its 97 its English else not. Check out this question :
