Re: [Echo-list] Getting lost focus event in text field

[Georg S. <geo...@we...>]

to fulfill the requirements you can do the following:

1. create a new component based on nextapp.echo.TextField.

2. in your TextFieldUI change the SERVICE_TEXT_FIELD_SCRIPT to a
modified one:

[code]
function E_textFieldKeyPress(event, E_id, E_value) {
    var E_code;

    if (event.keyCode) {
        E_code = event.keyCode;
    } else {
        E_code = event.which;
    }
    
    if (E_code == 13) {
        E_setParameter(E_id, E_value);
        E_setAction(E_id, "enter");
    }
    
    if(E_code == 9) {
        E_setParameter(E_id, E_value);
        E_setAction(E_id, "tab");
    }
}
[/code]

This script detects the TAB (9) key and notifies the server
with E_setAction(...)

If you want to distinct whether "enter" or "tab" was pressed
modify the clientAction-Method of your TextFieldUI to something
like this:

[code]
 public void clientAction(String command) {		
   if (renderedActive) {
     if("tab".compareTo(command) == 0)
       doTabWork();
     else {
       TextField textField = (TextField) getComponent();
       textField.fireActionEvent();	
     }
   }
}
[/code]

best regards,

  Georg
