Question

您好我想从div获取标签值并将其显示在html div标签中。我正在构建一个带有播放列表的html5视频播放器，只要我点击缩略图，视频就会发生变化，并且每次都会为div添加不同的标签。我想在html中打印该标签，并在每次显示新视频时更改它。我尝试过一些东西，但无法让它发挥作用。 jsfiddle https://jsfiddle.net/zo8tcuxs/1/

我的代码是：

<section id="video-container">
    <video id="videoarea" controls="controls" poster="" src="" id="video1" ></video>
<div id="description" label="" type="text"> </div>
<ul id="playlist">
    <li id="videoweek1" movieurl="http://clips.vorwaerts-gmbh.de/VfE_html5.mp4" label="This is video number 1 " type="video/mp4" moviesposter="http://html5videoformatconverter.com/data/images/screen.jpg">
    <img src="http://html5videoformatconverter.com/data/images/screen.jpg" class="video-thumbnail">
</li>
    <li id="videoweek2" movieurl="http://clips.vorwaerts-gmbh.de/VfE_html5.mp4" label="This is video number 2 " type="video/mp4" > <img src="http://html5videoformatconverter.com/data/images/screen.jpg" class="video-thumbnail"></li> 
</ul>
</section>

$(function() {
    $("#playlist li").on("click", function() {
        $("#videoarea").attr({
            "src": $(this).attr("movieurl"),
            "poster": "",
            "autoplay": "autoplay"
        })
    })
    $("#playlist li").on("click", function() {
        $("#description").attr({
            "label": $(this).attr("label")
        })
    })
    $("#videoarea").attr({
        "src": $("#playlist li").eq(0).attr("movieurl"),
        "poster": $("#playlist li").eq(0).attr("moviesposter")
    })



})

Answer 1

标签没有值，它在> html here </（开始和结束标记）下有html。试试这个：

$( function() {
    var lblTxt = $('#label').html();
    $('#div').html(lblTxt);
});

HTML

<label id="label">Hello</label>

<div id="div">
</div>

Answer 2

您需要设置目标.text()元素的.html() / div。

    $("#description").attr({
        "label": $(this).attr("label")
    }).text($(this).attr("label"))
