回答1:

Try this:

$('#wrapper').toggleClass('close');

This will add a close class when it is not there and removes the class when it's there

Finally made it Here is my solution:

$(document).ready(function(){
$('img.image, img.big_image').live('click', function(){
    if (!$('.big_image').length) {
        $('.image').addClass('close');
        $('#wrapper').append('<img class="big_image" src="'+this.src+'" />');
    }
    else
    {
        $('.image').removeClass('close');
        $('.big_image').remove();
    }
})
})

hope it will help

回答3:

 if($('#wrapper').hasClass('close')) {$('#wrapper').removeClass('class')}

You probably mean:

 if($('#wrapper').hasClass('close')) {$('#wrapper').removeClass('close')}
