用过Arcgis Server for JavaScript API肯定知道InfoWIndow。你在用InfoWindow的时候会发现各种问题,比如不能全然显示的问题,遮盖对象的问题等等。所以呢我在实现这个功能的时候动了下脑子,想自己用div+css弄一个,倒腾了半天,弄出来了一个例如以下所看到的的:
做的比較丑陋,样式方面还得好好下下功夫。东西是差点儿相同实现了,以下说说思路:
首先。DIV定义,这个样式,我定义了5个div,各自是infowin,title,colse,content。arrow,当中。infowin是整个InfoWindow的大框架,title为标题。close为关闭button,content为主要内容,arrow为以下的小尾巴。我们能够将这个小尾巴做的长一点。以免对象被遮盖的情况,代码为:
<div id="mapDiv"> <div id="infowin"> <div id="close" onClick="closeInfoWin()">X</div> <div id="title"></div> <div id="content"></div> <div id="arrow"></div> </div> </div>
<style> html, body, #mapDiv { padding:0; margin:0; height:100%; font-size:10px; position: relative; } #infowin { display:none; z-index:10000; } #close { float:right; padding-top:10px; font-weight:bold; font-size:12px; color:#FFF; border:#000 1px solid; height:20px; width:20px; text-align:center; } #close:hover { cursor:pointer; } #title { background-color:#666; padding:10px; font-weight:bold; font-size:12px; } #content { padding-left:10px; padding-top:10px; background-color:#999; height:200px; } #arrow { background-image:url(arrow.png); height:30px; } </style>样式定义完之后就得考虑事件了,一般InfoWindow是在点击某个对象时弹出来的,所以我们得定义对象图层的click事件:
function leftClick(evt){
infowin.style.display="none";
var strtitle="城市名称"
var strcontent = "****是一座漂亮的城市<br><br>****是一座好看的城市<br><br>****是一座富饶的城市<br><br>****是一座漂亮的城市";
infowin.style.left=(evt.clientX-width/2)+"px";
infowin.style.top=(evt.clientY-height-50)+"px";
infowin.style.position="absolute";
infowin.style.width=width+"px";
infowin.style.height=height+"px";
infowin.style.display="block";
title.innerHTML = strtitle;
content.innerHTML = strcontent;
}
//鼠标单击
featurelayercity.on("click", leftClick);
点击对象,在鼠标的点击位置出现。所以我们得将infowin的position样式设为absolute。并定义left和top分别为clientX和clientY,并将其display设置为block,将其显示,实现的具体代码例如以下:
<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <!--The viewport meta tag is used to improve the presentation and behavior of the samples on iOS devices--> <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"> <title>Feature Layer - display results as an InfoWindow onHover</title> <link rel="stylesheet" href="http://localhost/arcgis_js_api/library/3.8/3.8/js/dojo/dijit/themes/claro/claro.css"> <link rel="stylesheet" href="http://localhost/arcgis_js_api/library/3.8/3.8/js/dojo/dijit/themes/tundra/tundra.css"> <link rel="stylesheet" href="http://localhost/arcgis_js_api/library/3.8/3.8/js/esri/css/esri.css"> <style> html, body, #mapDiv { padding:0; margin:0; height:100%; font-size:10px; position: relative; } #infowin { display:none; z-index:10000; } #close { float:right; padding-top:10px; font-weight:bold; font-size:12px; color:#FFF; border:#000 1px solid; height:20px; width:20px; text-align:center; } #close:hover { cursor:pointer; } #title { background-color:#666; padding:10px; font-weight:bold; font-size:12px; } #content { padding-left:10px; padding-top:10px; background-color:#999; height:200px; } #arrow { background-image:url(arrow.png); height:30px; } </style> <script src="http://js.arcgis.com/3.9/"></script> <script> var infowin,colse,title,content; var width=400,height=230; var closeInfoWin = function (evt){ infowin=document.getElementById("infowin"); infowin.style.display="none"; }; require([ "esri/map", //地图 "esri/layers/ArcGISTiledMapServiceLayer", "esri/layers/FeatureLayer",//特征层 "esri/symbols/PictureMarkerSymbol",//图片点符号 "esri/renderers/SimpleRenderer", //简单渲染 "esri/graphic", //图片 "esri/lang", "dojo/domReady!" ], function( Map,ArcGISTiledMapServiceLayer,FeatureLayer,PictureMarkerSymbol,SimpleRenderer,esriLang ) { var map = new Map("mapDiv", { logo:false, center: [106.6854, 35.8364], zoom: 4, slider: true }); var shpServiceURL="***************************************"; var shpTitlelayer=new ArcGISTiledMapServiceLayer(shpServiceURL); map.addLayer(shpTitlelayer); //-------------------------------------------------------------------------------------------------------- var featurelayercity = new FeatureLayer("******************************************************", { mode: FeatureLayer.MODE_SNAPSHOT, outFields: ["*"] }); var pmsRed = new PictureMarkerSymbol(‘../images/location_icon_blue.png‘, 20, 20).setOffset(0, 15); //简单渲染 var sr=new SimpleRenderer(pmsRed); featurelayercity.setRenderer(sr); map.addLayer(featurelayercity); infowin = document.getElementById("infowin"); colse = document.getElementById("close"); title = document.getElementById("title"); content = document.getElementById("content"); function leftClick(evt){ infowin.style.display="none"; var strtitle="城市名称" var strcontent = "****是一座漂亮的城市<br><br>****是一座好看的城市<br><br>****是一座富饶的城市<br><br>****是一座漂亮的城市"; infowin.style.left=(evt.clientX-width/2)+"px"; infowin.style.top=(evt.clientY-height-50)+"px"; infowin.style.position="absolute"; infowin.style.width=width+"px"; infowin.style.height=height+"px"; infowin.style.display="block"; title.innerHTML = strtitle; content.innerHTML = strcontent; } //鼠标单击 featurelayercity.on("click", leftClick); }); </script> </head> <body class="tundra"> <div id="mapDiv"> <div id="infowin"> <div id="close" onClick="closeInfoWin()">X</div> <div id="title"></div> <div id="content"></div> <div id="arrow"></div> </div> </div> </body> </html>眼下仅仅实现到了这儿, 还有下面问题待解决:1、地图拖动后infowin随着地图的联动。2、地图缩放后infowin随着地图的联动;3、内容不在可视范围时候的移动;4、样式。挺难看的。希望有人实现后共享下代码,造福全GISer。
