I have a custom dropdown in angular JS which is a combination of textbox and list. Here on keydown event I am checking the key code and getting the char from String.fromCharCode(keyCode). and apply the style(highlighted) for the typed character from the list. This works fine for a single character.

for example in my list iam having {'india','ireland','egypt','england','nigeria'}

Here my code works if I type e it will point to the first country Egypt. My requirement is if I type en continuously it should highlight England, but this is not happening. As soon as I type n it will highlight Nigeria. because the keydown event is immediately firing and it is selecting for next char entered.

elem.on('keydown.ddl', function (e) {

    case (keyCode >= 65 && keyCode <= 90):

        var keyChar = String.fromCharCode(keyCode); //this give
        //here i am changing the style
        break;
});

Why don't you use directly the value in your textbox? – SinDeus Jun 09 '17 at 08:32
together text box and list should function like a dropdown. until i press enter key the textbox should be null – coder Jun 09 '17 at 08:34
