Trouble with the div element's change event

Hey there!

I'm having trouble with this jQuery code that is supposed to fade in or fade out a div based on its contents.

Here is the HTML code:

<div class="mainContentWrapper">
    sample text
</div>

And here is the CSS code:

div.mainContentWrapper{
display: none;
width: 80%;
margin: 0.5% 10%;
padding: 0.5% 3%;
box-sizing: border-box;

border-radius: 4px;
border: 0.15em solid #1C86EE;
background-color: rgba(255,255,255,0.65);
}

Lastly, the jQuery function I've been trying to use:

$(document).ready(function(){
$('.mainContentWrapper').on('change',function(){
    var mainContentWrapper_str=$.trim($(this).text());
    if(mainContentWrapper_str.length==0){
        $('.mainContentWrapper').fadeOut(500);
    }else{
        $('.mainContentWrapper').fadeIn(500);
    }
});
});

Answer №1

onChange does not work for modifications to the css. It is designed for interactive components like <input> or <textarea>.

Answer №2

Using onChange is limited to <input>, <select>, and <textarea> elements.
