Question

I am trying to insert a specific character say the letter “H” every time a key is pressed in another text box.

Eg.

Text box 1: Type your name

Text box 2: HHHHHHHHHHHHHH

I have tried

$('#cartText16132').keyup( function() {
    $('input#test').val('1');
});

But that only inserts one “1”

Hope that makes sense.

Answer 1

The following code should do what you want:

$("#cartText16132").keyup(function() {
    $("#test").val(this.value.replace(/./g, "H"));
});​

Another solution without regular expressions:

$("#cartText16132").keyup(function() {
    $("#test").val(Array(this.value.length + 1).join("H"));
});​
