添加指向活动标签的指针以显示

时间：2018-04-19 05:48:43

标签： javascript html css

我创建了一个视频库，以标签方式显示4个视频。

功能正常，设计也正常，但我需要在第二栏中添加指向活动视频的指针/箭头

// Video Tabs script
InitPlayVideoTabs();
			      
function InitPlayVideoTabs() {
    $('.hp-video-a').click(function (e) {
        // alert('inside function');
        e.preventDefault();
        var URL = $(this).attr('href');
        var htm = '<iframe width="100%" class="hp-active-iframe" min-height="324" src="http://www.youtube.com/embed/' + URL + '?showinfo=0&autoplay=1" frameborder="0" allowfullscreen="1" ></iframe>';

	$('.hp-video-a').css("background","none");
	$(this).css("background","#eee");
			 
	//code to autoplay video
	//$(".hp-active-iframe")[0].src += "&autoplay=1";
	//ev.preventDefault();
				
        // alert(URL);
        $(".hp-active-video-title").html($(this).find(".hp-video-title").html());
        $(".hp-active-video-date").html($(this).find(".hp-video-date").html());
        $('.hp-active-iframe').attr('src', URL);

        return false;
    });

你能检查一下：

我添加了一些代码：

在CSS中：

.hp-video-right-col a:active i.right, .hp-video-right-col a:focus i.right{
  border: solid black;
  border-width: 0 6px 6px 0;
  display: inline-block;
  padding: 3px;
  transform: rotate(-45deg);
  -webkit-transform: rotate(-45deg);
}

在所有a代码中的代码中：

<div style="float:left; padding-right:10px; padding-top:25px">
    <i class="right"></i>
</div>

工作小提琴如下：

// Video Tabs script
InitPlayVideoTabs();

function InitPlayVideoTabs() {

  $('.hp-video-a').click(function(e) {

您可以使用类添加三角形。我在消息来源中记录了我添加/删除/更改的内容。 HTML未受影响。

您只需要为初始加载设置三角形。
