为什么我的Jquery淡化功能不起作用？

时间：2016-11-07 03:45:45

标签： javascript jquery html css

我是Jquery的新手，正在尝试将其实施到我的网站中。我正在尝试在滚动时淡化（向上）我的第一行图片。但由于某种原因，他们不会滚动。似乎无法找到解决方案，有什么帮助吗？

    $(function() {

            if (location.pathname.replace(/^\//,'') == this.pathname.replace(/^\//,'') && location.hostname == this.hostname) {

                target = target.length ? target : $('[name=' + this.hash.slice(1) +']');
                if (target.length) {
                    $('html, body').animate({
                        scrollTop: target.offset().top
                    }, 1000);

    });


    // GALLERY FADEIN ----------------

    $('.js--wp-1').waypoint(function(direction) {

    }, {
        offset: '50%'
    });


});

试试这个： -

＆＃13;
＆＃13; 
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
    $(".btn1").click(function(){
        $("p").fadeOut()
    });
    $(".btn2").click(function(){
        $("p").fadeIn();
    });
});
</script>
</head>
<body>

<p>This is a paragraph.</p>

<button class="btn1">Fade out</button>
<button class="btn2">Fade in</button>

</body>
</html>
＆＃13;
＆＃13;
＆＃13;

或

$('#message').hide().html("You clicked on a checkbox.").fadeIn('slow');
