Question

。我正在尝试制作一些画廊。想要使用addClass显示图像，然后单击相同的位置以删除此新类我google寻求帮助，但是在试图让它正常工作一小时之后，我正在请求你的帮助。我在这里找到了反向选项的解决方案（首先删除并添加）

代码：

 <script type="text/javascript" src="http://www.s-ola.me/js/jquery.nailthumb.1.1.min.js"></script>
<style>

#window {
width:              570px;
height:             455px;
position:           relative;
background-color:   grey;
padding:            20px;
margin:             0 auto;
top:                50%;
margin-top:         -225px;
}

.image {
display:    inline-block;
margin:     5px;
}

 #wrapper {
width:              568px;
height:             455px;
position:           absolute;
}

.close {
display:    none;
}
.big_image{
width:      100%;
display:    block;
}
</style>

$(document).ready(function(){

$('img').click(function(){
    $('.image').toggleClass('close');
    $('#wrapper').append('<img src="'+this.src+'" class="big_image" />');

})
$(document).ready(function(){
$('.big_image').click(function(){
    if($('.big_image')) {$('.big_image').remove(); $('.image').toggleClass('close'); }
})

})

</script>
</body>
</html>

请告诉我错误的地方。

再次感谢。阿列克谢 alexela.biz

Answer 1

试试这个：

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

这将在不存在时添加一个close类，并在它出现时删除该类

Answer 2

终于做到了这是我的解决方案：

$(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();
    }
})
})

希望它会有所帮助

Answer 3

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

你可能意味着：

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

addClass（）然后单击removeClass（）（jquery）
