Display the X button solely once text has been inputted into the textbox

Question

Display the X button solely once text has been inputted into the textbox

I have integrated a text clearing plugin from here in my project to allow users to clear the input field by clicking on an X button. However, I want to modify the code so that the X button only appears when there is text entered in the textbox. I attempted to set a condition in the JavaScript code using the return statement:

if ($('#search').val().length != 0)

but it did not yield the desired results. Below is the snippet of code I tried:

$(document).ready(function(){
    if ($('#search').val().length != 0){
        $('#search').clearable();
        $('.divclearable').show();
    }
    else{
        $('.divclearable').hide();
    }
});

Your assistance with this issue would be greatly appreciated.

Implement a listener for the keyup event -

$(function () {
    $("#search").on("keyup", function() {
        if ($('#search').val().length != 0){
            $('#search').clearable();
            $('.divclearable').show();
        }
        else{
            $('.divclearable').hide();
        }
    });
});

Upon examining the CSS, it is evident that the button belongs to the clearlink class.

To hide it, you can simply use $("a.clearlink").hide().

This method caters to events beyond basic key presses:

$('.divclearable > input').change(
    function() 
    {
        if($(this).val().length == 0)
           $(this).closest('a.clearlink').hide();
        else
           $(this).closest('a.clearlink').show();
    }
);

Is it possible for the jquery change event to trigger when javascript changes an element's text?

To ensure that the clear button both hides and clears text, consider adding a click event. However, be cautious of potential conflicts with the library you are using.

$("#search").change(check_input);
$('.divclearable').click(check_input);
check_input = function(){
    if ($('#search').val().length != 0){
        $('#search').clearable();
        $('.divclearable').show();
    }
    else{
        $('.divclearable').hide();
    }
};

Let's discuss the logic, but remember, you'll need to implement it yourself: There's a CSS class known as "clearlink" which shows the close button. You can customize it by setting one of the initial values to be: display: none. Then, in your JQuery code, when you detect a length change, use a method to change display: none to block. Alternatively, you could create a copy of clearlink called clearlink1 and change the class name of the element.

You can easily do this by using the Inspect Element feature in your browser.
