jQuery Failing to Work

I'm experimenting with creating a falling effect for a DIV element when a piece of text is hovered over. The original effect can be seen here.

var $dropDiv = $('#dropDiv');
$('#holder p').on('hover', function () {
    // Get position of the clicked div
    var offset = $(this).offset();

    // Get dimensions of the clicked div
    var h = $(this).outerHeight();
    var w = $(this).outerWidth();

    // Get dimensions of the falling div
    var dh = $dropDiv.outerHeight();
    var dw = $dropDiv.outerWidth();

    // Calculate initial horizontal position
    var initLeft = offset.left + ((w / 2) - (dw / 2));

    // Animate the falling effect
    $dropDiv.css({
        left: initLeft,
        top: $(window).scrollTop() - dh,
        opacity: 0,
        display: 'block'
    }).animate({
        left: initLeft,
        top: offset.top - dh,
        opacity: 1
    }, 800, 'easeOutBounce');
});

This is the code I've written. Initially, I thought the issue was with the libraries, so I updated them to match the versions used in the fiddle.

<script src="fall.js"></script>
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js"></script>

The fiddle also had some specific CSS styling which I incorporated into my code.

#holder {
    position: absolute;
    top: 200px;
    left: 100px;   
}
#dropDiv {
    display: none;
    position: absolute;
    top: -20px;
    background: #ccc; 
}

Despite checking the error console and finding no issues, the effect still doesn't work. I'm using Safari Version 5.1.10 and hoping to make it work for both me and Chrome users. What could be the problem and how can I resolve it?

Answer №1

This is the proposed sequence.

<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js"></script>
<script src="fall.js"></script>

Answer №2

To ensure proper execution, enclose your code with:

$(document).ready(function() {

 //your code here

});

There is a chance that your javascript is not running due to it being executed before the elements are fully loaded on the DOM.

Additionally,

If your specific javascript resides in fall.js and utilizes jquery, make sure to load the fall.js file after jquery.

Answer №3

Can you share where you have placed your code? I encountered a similar issue.

<html>
    <head>
        <script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
        <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js"></script>
    </head>
    <body>
      YOUR HTML CODE
     <script type="text/javascript> your code</script>
     or
     <script src="fall.js"></script>
    </body>
</html>

Make sure to place your jQuery code after the html code, at the bottom in the tag for it to work correctly.

It's also important to wrap your code inside a 'ready' function.

$(document).ready(function(){
    your code here...
})

Answer №4

To ensure proper functionality, follow these 2 steps:

1) SEQUENCING - When using jQuery library functions in your JavaScript code, make sure to include the jQuery file first

<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js"></script>
<script src="fall.js"></script>

2) WAIT FOR DOM ELEMENTS - Ensure that the JavaScript/script either loads last in the body section or use the jQuery DOM ready event (More Information Available Here)

Answer №5

There seems to be a slight mix-up between Javascript and CSS in this code snippet.

$('#holder p').on( 'mouseover', function() {
    // code
});

Answer №6

One possible solution is to utilize:

$(function(){
   //insert your code within this function
})
