margin ges code total 點擊 上下 fin move sub
1.橫向滾動條.
div.1 > div.2 > img img img
第一: 設置 div.1 一個固定的寬度 和高度 . 例如寬度 700px; 高度是 120px; 設置 overflow-x
第二; 每個圖片的 寬度是 150px, 高度 100px( 比 div.1 小, 要可以顯示橫向滾動條
第三: 重點 . 設置 div.2 的寬度 . 如果有 10個圖片, 每個圖片margin-right 為 10px, 那麽 div.2 的寬度就是 (150+10)*10
這裏要考慮 inline-box 的元素之間有間隙. 可以設置 div.2 的font-size 為 0px; img 的font-size 為 16px;
參考樣式:
1 .kecheng_03_content { 2 width: 100%; 3 height: 120px; 4 overflow-x: auto; 5 /*border: 1px solid red;*/ 6 margin-top: 20px; 7 } 8 9 .kecheng_03_content .xuan { 10 width: 750px; 11 font-size: 0px; 12 -webkit-text-size-adjust:none;13 } 14 15 .kecheng_03_content .xuan div { 16 width: 120px; 17 height: 90px; 18 display: inline-block; 19 margin-right: 20px; 20 box-shadow: 0px 0px 2px 2px #DBDBDB; 21 22 } 23 24 .kecheng_03_content .xuan div video { 25 width: 120px;26 height: 90px; 27 } 28 29 .kecheng_03_content .xuan div img { 30 width: 120px; 31 height: 90px; 32 }
2. 點擊切換視頻或者圖片.
要求:
1)點擊下面滾動條中的圖片, 圖片對應的視頻可以切換;
2)也可以 直接點擊 perv 或者 next 切換視頻.
---------------------------
保證視頻 和圖片 都是 這樣的命名方法: 1.mp4 , 2.mp4, 3.mp4, 4.mp4, 5.mp4; 1.png, 2.png , 3.png , 4.png , 5.png
---------------------------
2-1: html結構:

第9行: 設置了 data-num="1" data-totalnum="5" data-subsrc="<?php echo PROJECT . ‘Application/View/Home/Course/dzsk/video/‘; ?>"
data-num 當前的播放的是第一個視頻, data-totalnum 總共視頻是 5個. data-subsrc 視頻存放的上級地址. 視頻播放地址 = data-subsrc + 1.mp4
第 16- 18行:
<div data-num="1" onclick="jumpContent(this)">
17 <img data-videosrc="<?php echo PROJECT . ‘Application/View/Home/Course/dzsk/video/1.mp4‘; ?>" src="<?php echo PROJECT . ‘Application/View/Home/Course/dzsk/video/1.png‘; ?>">
18 </div>
data-num 表示點擊這個圖片,對應的視頻是 1.mp4
data-videoserc 表示的這個圖片對應的視頻地址.
2-2: 上一個,下一個對應的js 函數.
