地图卷帘实现——参考ArcGIS API

xiaoxiao2023-09-30 131

添加点、线、面图层

参考教程：ArcGIS API for Javascript本示例参考：Add Layers To 2D Map编辑软件:Hbuilder功能：鼠标在地图上移动，实现两幅地图的卷帘效果。

【? Code First ?】

Part 1：HTML

<html> <head> <meta charset="utf-8"> <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no"> <title>Lux's Map</title> <link rel="stylesheet" href="css/css01.css" /> <link rel="stylesheet" href="css/css04.css" /> <link rel="stylesheet" href="https://js.arcgis.com/4.10/esri/css/main.css"> <link rel="stylesheet" href="css/css_menu.css" /> <script src="https://js.arcgis.com/4.10/"></script> <script src="js/js04.js"></script> </head> <body> <ul> <li> <a class="entypo-star" href="demo01.html"></a> <span>ChangeBaseMap</span> </li> <li> <a class="entypo-newspaper" href="demo02.html"></a> <span>AddLayers</span> </li> <li> <a class="entypo-link" href="demo03.html"></a> <span>LinkMap</span> </li> <li> <a class="entypo-menu" href="demo04.html"></a> <span>LayerSwipe</span> </li> </ul> <div onmousemove="SwipeMap()"> <div id="viewDiv01"></div> <div id="viewDiv02"></div> </div> </body> </html>

Part 2：CSS

#viewDiv02 { position: absolute; padding: 0; margin: 0; top: 0px; right: 0px; height: 100%; width: 100%; }

Part 3：Javascript

require([ "esri/Map", "esri/views/MapView" ], function(Map, MapView) { //**********************************************功能：swip map********************************************************** var map01 = new Map({ basemap: "streets" }); var view = new MapView({ container: "viewDiv01", map: map01, center: [-118.71511,34.09042], zoom: 11 }); var map02 = new Map({ basemap: "gray" }); var view = new MapView({ container: "viewDiv02", map: map02, center: [-118.71511,34.09042], zoom: 11 }); }); function SwipeMap() { console.log(event.clientX); //鼠标屏幕x坐标等于上层地图宽度 document.getElementById("viewDiv02").style.clip="rect(0px,"+event.clientX +"px,768px,0px)"; }

Part 4：Menu（CSS）

@import url(http://weloveiconfonts.com/api/?family=entypo); /* entypo */ [class*="entypo-"]:before { font-family: 'entypo', sans-serif; } @-webkit-keyframes flip { 0%{-webkit-transform:rotateY(0deg); opacity:1;} 100%{-webkit-transform:rotateY(95deg); opacity:0;} } @-moz-keyframes flip { 0%{-webkit-transform:rotateY(0deg); opacity:1;} 100%{-webkit-transform:rotateY(95deg); opacity:0;} } @-o-keyframes flip { 0%{-webkit-transform:rotateY(0deg); opacity:1;} 100%{-webkit-transform:rotateY(95deg); opacity:0;} } @keyframes flip { 0%{-webkit-transform:rotateY(0deg); opacity:1;} 100%{-webkit-transform:rotateY(95deg); opacity:0;} } body { background:url(forestblur.jpg) no-repeat; background-size:cover 100%; } h2 { color: #555; text-align: center; } ul { position:absolute; top: 45px; left: 15px; margin:50px auto; padding:0; z-index: 9; width:200px; height:220px; list-style:none; -webkit-perspective:1000; -moz-perspective:1000; -o-perspective:1000; perspective:1000; } li { margin:2px 0; padding:0; } li a { display:block; height:18px; width:20px; background:rgba(155,155,155,0.5); color:#fff; padding:8px 6px; text-decoration:none; text-align:center; } li span { width:154px; float:left; text-align:center; background:rgba(155,155,155,0.5); color:#fff; margin:-34px 34px; padding:8px 6px; transform-origin:0%; opacity:0; -webkit-transform:rotateY(95deg); -webkit-transition:.5s; -moz-transition:.5s; -o-transition:.5s; transition:.5s; -webkit-animation: flip 2s; -moz-animation: flip 2s; -o-animation: flip 2s; animation: flip 2s; } span[class='menu']{-webkit-animation:none;} li:nth-child(2) span { -webkit-animation-delay:.5s; -moz-animation-delay:.5s; -o-animation-delay:.5s; animation-delay:.5s;} li:nth-child(3) span { -webkit-animation-delay:.4s; -moz-animation-delay:.4s; -o-animation-delay:.4s; animation-delay:.4s;} li:nth-child(4) span { -webkit-animation-delay:.3s; -moz-animation-delay:.3s; -o-animation-delay:.3s; animation-delay:.3s;} li:nth-child(5) span { -webkit-animation-delay:.2s; -moz-animation-delay:.2s; -o-animation-delay:.2s; animation-delay:.2s;} li:nth-child(6) span { -webkit-animation-delay:.1s; -moz-animation-delay:.1s; -o-animation-delay:.1s; animation-delay:.1s;} li a:hover ~ span { opacity:1; -webkit-transform:rotateY(0deg); -moz-transform:rotateY(0deg); -o-transform:rotateY(0deg); transform:rotateY(0deg); -webkit-transition:.5s; -moz-transition:.5s; -o-transition:.5s; transition:.5s; }

这个是功能的全部代码，我的项目界面是这样嘚，本模块功能对应Demo03、js03、css03文件：代码下载地址：链接：WebGIS_Demo_X4 提取码：uy3p

····其中Demo04是该示例代码，对应css04，对应js04；界面中有设置一个功能切换菜单Menu（对应样式为CSS_Menu）；img为第一个功能切换底图时界面上显示的图片引用；

功能实现界面如下：

功能实现思路：两幅地图卷帘，则在对应的地图显示窗口（两个div）中，两幅地图位置完全重合即可实现，同时设置上面的地图的div窗口的宽度与鼠标的屏幕坐标的x值一致即可；
