Caps Lock On/Off indicator in Oracle APEX

-

 

In this post I will be explaining how to show Caps Lock On/Off indicator in Oracle APEX.

Follow the below steps to achieve this:

1) Create a Page Item (Type of the item is Password).

     Item Name: P33_PASSWORD (Use the item name in your page instead of this)

2) Paste the below CSS code in the Inline Section

#caps-lock-div{

    color:rgb(250, 76, 76);

    font-size: 1.3rem;

    line-height: 2rem;

}

3) Paste the below JavaScript code in the Function and Global Variable Declaration section

var password = document.getElementById("P33_PASSWORD");
var $password = $("#P33_PASSWORD").parent().parent();
var element = '<span id="caps-lock-div" class="fa fa-warning"> CapsLock key is on!</span>';

var capsLockCheck = function (event) {
    let $element = $('#caps-lock-div');

    if (event.getModifierState("CapsLock")) {
        if($element.length == 0){    
            $password.append(element);
        }
    } 
    else {
        if($element.length){
            $element.remove();
        }  
    }  
};

password.addEventListener('keyup', capsLockCheck, false);
password.addEventListener('mousedown', capsLockCheck, false);


Note: Use the item name in your page instead of  P33_PASSWORD

      Hey Sasha, I have tested the above JavaScript code. It works fine for me. Please see the DEMO.

      If you put the code in the Item post text section, the message will be displayed to the right of the Item(not below), which most of the users do not prefer. That is why I have chosen this approach.
