If checkbox is checked - show input field. Works in JSFiddle, not on website


I probably have been staring at this too long and am missing something obvious, but: why is this working fine in JSFiddle and NOT when I upload it??

The alert at the end is showing up on the test website, but the "showthis" is also visible no matter what.

<script type="text/javascript" src="scripts/jquery-1.11.0.min.js"></script>
<script type="text/javascript" src="scripts/showfield.js"></script>
</head>

<body>

<input type="checkbox" name="checkbox" id="checkbox" value="checkbox" />
<br />
<input id="showthis" name="showthis" size="50" type="text" value="text here"/>

</body>
</html>

jQuery (I've downloaded a minified jQuery 1.11.0 , which is what's working in JSFiddle)

//hide field by default
$('input[name="showthis"]').hide();

//show it when the checkbox is clicked
$('input[name="checkbox"]').on('click', function(){
if ( $(this).prop('checked') ) {
    $('input[name="showthis"]').fadeIn();
} 
else {
    $('input[name="showthis"]').hide();
}
});


// the alert is showing fine 
alert ("hello");

Solution

  • Wrap your code in a loading event. This is the newer, preferred, syntax (rather than $(window) or $(document)):

    $(function () {
        $('input[name="showthis"]').hide();
    
        //show it when the checkbox is clicked
        $('input[name="checkbox"]').on('click', function () {
            if ($(this).prop('checked')) {
                $('input[name="showthis"]').fadeIn();
            } else {
                $('input[name="showthis"]').hide();
            }
        });
    });
