无缝的jQuery字幕? [英] Seamless jQuery Marquee?

问题描述

是否有可能在jQuery中创建100％无缝的字幕(或仅使用JavaScript，但首选jQuery)?

Is it possible to create a 100% seamless marquee in jQuery (or just javascript but jQuery prefered)?

我制作了一个简单的选取框，该选取框向左移动直到离开屏幕为止，然后简单地(在视线之外)向右跳转并重新开始.但是我希望它没有等待.

I've made a simple marquee that moves left until it is off the screen then simply jumps (when out of view) to the right and starts again. However I would love it to not have the wait.

我想到的唯一方法是复制文本并将其放在第一个文本之后，然后再次交换它们.但是我不知道如何在jQuery中实现它，我一直在看jQuery的.clone()，但是不能使其正常工作，一切都会跳跃.

The only way I could think of doing this would be to duplicate the text and put it after the first text, then swap them round again. However I have no idea how to implement this in jQuery, I've been looking at jQuery's .clone() but can't get it working correctly, everything jumps.

有什么想法吗?

感谢您的时间，

推荐答案

给出以下标记:

<div id="marquee">My Text</div>

对于重复，我会做这样的事情:

For the duplication, I'd do something like this:

$("#marquee").wrapInner("span"); // wrap "My Text" with a new span
$("#marquee").append($("#marquee span").clone().hide()); // now there are two spans with "My Text"

移动和交换跨度非常简单.这是一个功能齐全的示例:

Moving and swapping the spans is pretty easy. Here's a fully functional example:

$(function() {

    var marquee = $("#marquee"); 
    marquee.css({"overflow": "hidden", "width": "100%"});

    // wrap "My Text" with a span (old versions of IE don't like divs inline-block)
    marquee.wrapInner("<span>");
    marquee.find("span").css({ "width": "50%", "display": "inline-block", "text-align":"center" }); 
    marquee.append(marquee.find("span").clone()); // now there are two spans with "My Text"

    // create an inner div twice as wide as the view port for animating the scroll
    marquee.wrapInner("<div>");
    marquee.find("div").css("width", "200%");

    // create a function which animates the div
    // $.animate takes a callback for when the animation completes
    var reset = function() {
        $(this).css("margin-left", "0%");
        $(this).animate({ "margin-left": "-100%" }, 3000, 'linear', reset);
    };

    // kick it off
    reset.call(marquee.find("div"));

});

查看实际效果.

免责声明:

对于任何专业网站，我都不推荐这样做.但是，如果您想重现1990年的复古外观，这可能会很有用.

I don't recommend this for any professional website. However, it might be useful if you're trying to reproduce a retro 1990's look.
