Thread: Change TextBox input language

again

Another one that I've been searching for a while..
how can i change a textbox input language from english to greek?
What I mean... In my keyboard I have 2 languages, english and greek. I want, when I type to a textbox, to write in greek, even if the language selected is english.
Thank you

how can I replace it while typing?

I mean, while typing the english characters to be replaced by the greek ones..

I'll try it and I'll let you know.. Thank you..

Why this doesn't work?

Code:

<%
function ChkStr(strT)
	strT = Replace(strT, "a", "α")
	strT = Replace(strT, "b", "β")
	ChkStr = strT
End Function
%>

<input type="text"
id="test" onKeyUp="ChkStr(this.id)">

Found it!

Code:

function greeklish(x)
{
var y=document.getElementById(x).value;
y=y.replace("a", "α");
y=y.replace("b", "β");
y=y.replace("g", "γ");
document.getElementById(x).value=y
}


<input type="text"
id="greek" onKeyUp="greeklish(this.id)">

I haven't add all the letters yet but it's OK, right?

I was just about to post this to see if it's any good

Code:

function change_letter(id){
  var txt = document.getElementById(id).value;
  var old_txt = '';
  var new_txt = '';
     for(var i=txt.length-1;i<txt.length;i++){
         old_txt = txt.charCodeAt(i);
         //chr ref for a=97 for z=123 isNaN takes care of any other key presses
            if(old_txt>=97&&old_txt<=123&&!isNaN(old_txt)){
               //difference in chr numbers between a and alpha is 848
               new_txt = String.fromCharCode(txt.charCodeAt(i)+848);
               //replace the old character for the new one
               document.getElementById(id).value = txt.replace(String.fromCharCode(old_txt), new_txt);
            }
     }
}
 

To use it:-

Code:

<input type="text" id="textbox1" onkeyup="change_letter(this.id)" /> 

I found the difference between the chr values of a and alpha to be 848. So it grabs the last letter from the textbox checks the value is between a and z and then adds 848 to the chr value. Then it replaces the old character with the new one. I thought this would save having to add all the letters manually.

The only slight problem with this method is where characters do not have direct replacements. Maybe you could add something in to filter these.

Hope that helps.

For the english characters that don't exist in greek I did this:

Code:

if (y.match("c")) 
{
alert("Μόνο ελληνικά");
y=y.replace("c", "");
}

The problem though is that with your code starts ok (a=α, b=β, ...) but then it replaces your "m" with our "n", your "k" with our "l" and other... it's not correct..

Yeah...I thought that might be a problem...

What you need to do is, if c isn't a letter in greek, any letters after c have to only have 847 added to them.

Then if, for example if j isn't a letter in greek, anything after j would only have 846 added to it.

Depending on how many letters don't have a replacement, perhaps a switch statement might be better.

Hope that makes sense...
