本文例項為大家分享了jQuery實現檢視圖片的具體程式碼,供大家參考,具體內容如下
HTML
<!-- 放縮圖的div --> <div class="sl"> <img src="images/1.jpg" /> <img src="images/2.jpg" /> <img src="images/3.jpg" /> </div> <!-- 實現關燈的div --> <div class="gd"></div> <div class="yt"> <!-- 左翻按鈕 --> <div class="left"> <img src="images/left.png" alt="jQuery實現檢視圖片功能" width="100"> </div> <div class="tp"> <!-- 展示原圖 --> <img src="images/1.jpg" class="show" /> <!--放開始和結束圖片的盒子 --> <div class="ss" style="display: none;"> <img src="images/start.png" alt="jQuery實現檢視圖片功能" width="50" class="start"> </div> </div> <!-- 右翻按鈕 --> <div class="right"> <img src="images/right.png" alt="jQuery實現檢視圖片功能" width="100"> </div> </div>
CSS
html,body{ padding: 0; margin: 0; } .sl img { width: 300px; } .gd { background-color: rgba(0,0.7); position: absolute; z-index: 900; display: none; top: 0; left: 0; } .sl { position: absolute; z-index: 888; display: flex; flex-wrap: wrap; justify-content: center; } .sl>img { width: 25%; } .yt { z-index: 990; position: absolute; display: none; left: 500px; top: 200px; } .tp { margin: 0 20px; } .yt>div { display: inline-block; } .left,.right { position: relative; top: -110px; cursor: pointer; } .ss { position: relative; width: 50px; height: 50px; left: 270px; } .start { z-index: 990; position: absolute; }
JS
var max = $(".sl img").length; $(function (e) { var width = $(window).width(); var height = $(window).height(); $(".gd").css({ "height": height,"width": width }); //左翻按鈕動畫 $(".left").hover( function () { $(this).animate({ "left": "-10" }); },function () { $(this).animate({ "left": "0" }); } ); //右翻按鈕動畫 $(".right").hover( function () { $(this).animate({ "right": "-10" }); },function () { $(this).animate({ "right": "0" }); } ); //被點選的縮圖 $(".sl>img").click(function (e) { $(".gd").show(500); $(".yt").fadeIn(800); var index = $(this).index(); //當前被點選圖片的索引 $(".tp>img").attr("src","images/" + (index + 1) + ".jpg"); //左翻 $(".left").click(function (e) { if (index - 1 < 0) { index = max - 1; } else { index = index - 1; } $(".tp>img").attr("src","images/" + (index + 1) + ".jpg"); }); //右翻 $(".right").click(function (e) { if (index == max - 1) { index = 0; } else { index = index + 1; } $(".tp>img").attr("src","images/" + (index + 1) + ".jpg"); }); //隱藏和顯示播放按鈕 $(".tp").hover( function () { $(".ss").fadeIn(500); $(this).animate({ "opacity": "0.7" },700); },function () { $(".ss").fadeOut(500); $(this).animate({ "opacity": "1" },700); } ); //點選開始播放 再次點選結束播放 let flag = true; $(".start").click(function () { if (flag == true) { time = setInterval(function () { if (index == max - 1) { index = 0; } else { index = index + 1; } $(".tp>img").attr("src","images/" + (index + 1) + ".jpg"); },2000); flag = false; $(".start").attr("src","images/stop.png"); } else { clearInterval(time); flag = true; $(".start").attr("src","images/start.png"); } }); let h = $(".tp>img").height(); $(".ss").css({ "top": -h / 2 - 25 }); //隱藏關燈效果 $(".gd").click(function () { $(".gd").hide(800); $(".yt").fadeOut(500); }); }); });
