The jQuery function is not functioning correctly

Currently, I am in the process of setting up an accordion menu using jQuery and CSS3. Everything is working perfectly fine so far except that the menu always opens upon page load and the code to hide it is not functioning as intended. Here's the link to the fiddle I have created:

Here is the jQuery code snippet I am working with:

$(document).ready(function() {

    //ACCORDION BUTTON ACTION (ON CLICK DO THE FOLLOWING)
    $('.zero_menu_title_collapse').click(function() {

        //REMOVE THE ON CLASS FROM ALL BUTTONS
        $('.zero_menu_title_collapse').removeClass('on');

        //CLOSE ALL OPEN SLIDES REGARDLESS
        $('.zero_menu_content').slideUp('normal');

        //CHECK IF THE NEXT SLIDE IS HIDDEN AND OPEN IT
        if($(this).next().is(':hidden') == true) {

            //ADD THE ON CLASS TO THE BUTTON
            $(this).addClass('on');

            //OPEN THE SLIDE
            $(this).next().slideDown('normal');
         } 

     });

    //ADDS THE .OVER CLASS FROM THE STYLESHEET ON MOUSEOVER 
    $('.').mouseover(function() {
        $(this).addClass('over');

    //ON MOUSEOUT REMOVE THE OVER CLASS
    }).mouseout(function() {
        $(this).removeClass('over');                                        
    });

    //CLOSES ALL S ON PAGE LOAD
    $('.zero_menu_content').hide();

});

Answer №1

To ensure your accordion content is initially hidden, include this CSS rule:

.zero_menu_content {
    display: none;
}

UPDATE: This version will not only hide the content but also correct any syntax errors in your code.

For additional reference, you can visit http://jsfiddle.net/dfsq/YU6nZ/15/

The unnecessary $('.zero_menu_content').hide(); has been removed as it is redundant with the CSS solution.

Answer №2

Learn how to access your browser's JavaScript console. I am encountering the following error message:

There seems to be a syntax error: .

This error is specifically related to this snippet of code:

$('.').mouseover(function() {
  ^^^

I am unsure about the correct format for this code, but the accordion feature functions properly once this block is removed.

Answer №3

There is a mistake in your code.

$('').mouseover(function() {
    $(this).addClass('over');
}).mouseout(function() { $(this).removeClass('over'); });

You will receive an error message saying undefined expression . in the console. This causes the code execution to halt at that point.

Answer №4

An error has been detected in your JavaScript code:

Uncaught Error: Syntax error, unrecognized expression: . 

The issue occurs when:

$('.').mouseover(function() {
    $(this).addClass('over');

//ON MOUSEOUT REMOVE THE OVER CLASS
}).mouseout(function() {
    $(this).removeClass('over');                                        
});

To fix the error, make the following adjustment:

//ADDS THE .OVER CLASS FROM THE STYLESHEET ON MOUSEOVER 
$('.zero_menu_content_row').mouseover(function() {
    $(this).addClass('over');

//ON MOUSEOUT REMOVE THE OVER CLASS
}).mouseout(function() {
    $(this).removeClass('over');                                        
});

Refer to this correct fiddle for more information: http://jsfiddle.net/YU6nZ/12/

Answer №5

//WHEN MOUSEOVER, ADD THE .OVER CLASS FROM THE STYLESHEET
$('.').mouseover(function() {
    $(this).addClass('over');

//ON MOUSEOUT, REMOVE THE OVER CLASS
}).mouseout(function() {
    $(this).removeClass('over');                                        
});

This code causes a JavaScript error preventing $('.zero_menu_content').hide(); from executing. Please check the browser console for error messages.

Answer №6

Give this a try:

 $(document).ready(function() {
/***************************************************************************************************************
HIDES ALL ZERO_MENU_CONTENT ON PAGE LOAD
***************************************************************************************************************/   
$('.zero_menu_content').hide();

//ON CLICK OF ACCORDION BUTTON, DO THE FOLLOWING ACTIONS
$('.zero_menu_title_collapse').click(function() {

    //REMOVE 'on' CLASS FROM ALL BUTTONS
    $('.zero_menu_title_collapse').removeClass('on');

    //CLOSE ALL OPEN SLIDES
    $('.zero_menu_content').slideUp('normal');

    //IF THE NEXT SLIDE IS HIDDEN, THEN SHOW IT
    if($(this).next().is(':hidden') == true) {

        //ADD 'on' CLASS TO THE BUTTON
        $(this).addClass('on');

        //SHOW THE SLIDE
        $(this).next().slideDown('normal');
     } 

 });


/*** REMOVE IF MOUSEOVER FUNCTIONALITY IS NOT NEEDED ***/

//ADD 'over' CLASS ON MOUSEOVER 
$('.').mouseover(function() {
    $(this).addClass('over');

//REMOVE 'over' CLASS ON MOUSEOUT
}).mouseout(function() {
    $(this).removeClass('over');                                        
});

/*** END REMOVAL OF MOUSEOVER FUNCTIONALITY ***/




});

I have moved your hide() function to the beginning of the script.

$(document).ready(function(){

});
