图像隐藏，然后鼠标移动淡入、淡出并再次淡入

发布于 2024-08-21 09:32:25 字数 919 浏览 8 评论 0原文

我试图让图像在 3 秒内没有鼠标操作时淡出，然后在再次移动鼠标时淡入。

如果有人能告诉我如何使图像隐藏直到鼠标移动，我也将不胜感激。因此，当页面加载时，在鼠标移动之前您看不到图像。

这就是我到目前为止所拥有的...

I am trying to get an image to fade out when there has been no mouse action for 3 seconds and then fades in when the mouse is again moved.

I would also be appreciative if anyone could tell me how I can make the image be hidden until the mouse moves. So when the page loads up you don't see the image until the mouse moves.

This is what I have so far...

            $(document).mousemove(function() {
            if (timer) {
            clearTimeout(timer);
            timer = 0;
            }
            $('#top:visible').fadeIn();
            timer = setTimeout(function() {
            $('#top').fadeOut()
            }, 3000)
            })
        </script>
        </head>
        <body>
            <div id="top">

            </div>
        </body>
    </html>

Thanks so much for your help!

我已经用一体式页面更新了我的答案。希望这会让事情变得更加清楚。最好将 javascript 放在自己的文件中，但这会让您继续前进。

确保此行：

<script type="text/javascript" src="jquery-1.4.1.min.js"></script>

正确指向具有正确位置和名称的 jQuery 文件。

让我知道进展如何。

I've updated my answer with an all-in-one page. Hopefully this will make things more clear. Better to have javascript in its own file, but this will get you going.

Make sure that this line:

<script type="text/javascript" src="jquery-1.4.1.min.js"></script>

correctly points to your jQuery file with the right location and name.

Let me know how it goes.

试试这个：

$(document).ready(function() {
    var timer;
    // hide initially
    $('#top').hide();

    $(document).mousemove(function() {
        if (timer) {
            clearTimeout(timer);
            timer = 0;
        }
        $('#top').fadeIn();
        timer = setTimeout(function() {
            $('#top').fadeOut();
        }, 3000)
    });
});

Try this:

$(document).ready(function() {
    var timer;
    // hide initially
    $('#top').hide();

    $(document).mousemove(function() {
        if (timer) {
            clearTimeout(timer);
            timer = 0;
        }
        $('#top').fadeIn();
        timer = setTimeout(function() {
            $('#top').fadeOut();
        }, 3000)
    });
});
