學會用bootstrap的modal和carousel，modalcarousel
bootstrap架構提供了很多好用的javascript組件，可以很方便的實現常用的js效果，比如點擊彈出一個div（modal）、下拉式功能表、旋轉木馬（carousel或slider），非常適合前端不專業的後端程式員使用。下面就來看下modal和carousel如何使用。
modal即點擊彈出div的效果，先看下。
代碼如下：
1 <!DOCTYPE html> 2 <html lang="zh"> 3 <head> 4 <title>Bootstrap Example</title> 5 <meta charset="utf-8"> 6 <meta name="viewport" content="width=device-width, initial-scale=1"> 7 <link rel="stylesheet" href="../../vendor/bootstrap-3.3.7-dist/css/bootstrap.min.css"> 8 <script src="../../vendor/jquery-3.0.0.min.js"></script> 9 <script src="../../vendor/bootstrap-3.3.7-dist/js/bootstrap.min.js"></script>10 </head>11 12 <body>13 <style>14 .prime-img {15 width: 100%;16 }17 .mw {18 width: 300px;19 }20 .box {21 margin: 150px auto;22 text-align: center;23 width: 150px;24 }25 </style>26 27 <div class="container">28 29 <div class="box">30 <h4>Modal Example</h2>31 <!-- Trigger the modal with a button -->32 <img data-toggle="modal" data-target="#myModal" class="prime-img" src="../../asset/images/p1.jpg" alt="">33 <h4 class="box-desc">花</h4>34 </div>35 </div>36 37 <!-- Modal -->38 <div class="modal fade" id="myModal" role="dialog">39 <div class="modal-dialog mw">40 <!-- Modal content-->41 <div class="modal-content">42 <div class="modal-header">43 <button type="button" class="close" data-dismiss="modal">×</button>44 <h4 class="modal-title">Modal</h4>45 </div>46 <div class="modal-body">47 <img class="prime-img" src="../../asset/images/p1.jpg" alt="">48 <div>紅花嬌豔</div>49 </div>50 <div class="modal-footer">51 <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>52 </div>53 </div>54 <!--End Modal content-->55 </div>56 </div>57 <!-- End Modal -->58 </div>59 </body>60 </html>
代碼第7-9行是需要引入的css和js，可以看到bootstrap.min.js依賴於jQuery。
第32行中的 data-target="#myModal" 指定了要彈出div的id，第38行開始的id為myModal的div就是彈出的實現。其中可以看到彈出的div內容被包含在.modal-content中，而它又被分成了三個部分，.modal-header、.modal-body、.modal-header。具體在使用時不用拘泥於上面的寫法，可以自己定義布局和樣式。
再看carousel(也可以叫slider)，即旋轉木馬，又叫投影片或滑塊。
看下，箭頭可以控制：
看下代碼：
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <title>Bootstrap Example</title> 5 <meta charset="utf-8"> 6 <meta name="viewport" content="width=device-width, initial-scale=1"> 7 <link rel="stylesheet" href="../../vendor/bootstrap-3.3.7-dist/css/bootstrap.min.css"> 8 <script src="../../vendor/jquery-3.0.0.min.js"></script> 9 <script src="../../vendor/bootstrap-3.3.7-dist/js/bootstrap.min.js"></script>10 <style>11 .carousel-inner > .item > img,12 .carousel-inner > .item > a > img {13 width: 70%;14 margin: auto;15 }16 </style>17 </head>18 <body>19 <div class="container">20 <br>21 <div id="myCarousel" class="carousel slide" data-ride="carousel">22 <!-- Indicators -->23 <ol class="carousel-indicators">24 <li data-target="#myCarousel" data-slide-to="0" class="active"></li>25 <li data-target="#myCarousel" data-slide-to="1"></li>26 <li data-target="#myCarousel" data-slide-to="2"></li>27 <li data-target="#myCarousel" data-slide-to="3"></li>28 </ol>29 30 <!-- Wrapper for slides -->31 <div class="carousel-inner" role="listbox">32 33 <div class="item active">34 <img src="../../asset/images/p1.jpg" alt="花" width="460" height="345">35 <div class="carousel-caption">36 <h3>花</h3>37 <p>紅花嬌豔</p>38 </div>39 </div>40 41 <div class="item">42 <img src="../../asset/images/p2.jpg" alt="樹" width="460" height="345">43 <div class="carousel-caption">44 <h3>樹</h3>45 <p>大木蒼翠</p>46 </div>47 </div>48 49 <div class="item">50 <img src="../../asset/images/p3.jpg" alt="海" width="460" height="345">51 <div class="carousel-caption">52 <h3>海</h3>53 <p>海浪洶湧</p>54 </div>55 </div>56 57 <div class="item">58 <img src="../../asset/images/p4.jpg" alt="湖" width="460" height="345">59 <div class="carousel-caption">60 <h3>湖</h3>61 <p>晚湖靜美</p>62 </div>63 </div>64 65 </div>66 67 <!-- Left and right controls -->68 <a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">69 <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>70 <span class="sr-only">Previous</span>71 </a>72 <a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">73 <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>74 <span class="sr-only">Next</span>75 </a>76 </div>77 </div>78 79 </body>80 </html>
整個滑動內容和控制元素都被#myCarousel的div包起來，它分為三部分：第23行ol包起來的li組成的按鈕，第31行開始到第65中是要滑動的3個.item元素，第67行後面是左右控制箭頭。
是不是很簡單，拿來就用。有時間再研究下如何把modal和carousel結合起來使用。
