问题描述
我必须在定位"小部件 (esri-icon-locate") 中添加自定义 SVG 文件,而不是来自 ArcGIS 的导航图标.问题是,默认图标出现在自定义 svg 文件的顶部.有没有办法隐藏默认图标?
I have to add a custon SVG file instead of the navigation icon from ArcGIS in the 'locate' widget ('esri-icon-locate'). Here the problem is, the default icon is appearing top of the custom svg file. Is there any way to hide the default icon?
view.when(_ => {
const n = document.getElementsByClassName("esri-icon-locate");
if (n && n.length === 1) {
n[0].classList += " mapnavigation"
}
});
和CSS,
.mapnavigation:before{
display: block;
background: url('mapnavigation.svg');
background-repeat: no-repeat;
background-size: 17px 17px;
background-color: #ffffff;
}
推荐答案
您已经非常接近解决方案了,您只需要将其设为节点的唯一类.看看我给你的例子,
You were really close to the solution, you just need to make it the only class of the node. Take a look at the example I put for you,
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no" />
<title>Locate button | Sample | ArcGIS API for JavaScript 4.18</title>
<link rel="stylesheet" href="https://js.arcgis.com/4.18/esri/themes/light/main.css" />
<style>
html,
body,
#viewDiv {
padding: 0;
margin: 0;
height: 100%;
width: 100%;
}
.my-svg-icon {
background: url(https://openlayers.org/en/latest/examples/data/square.svg);
width: 20px;
height: 20px;
}
</style>
<script src="https://js.arcgis.com/4.18/"></script>
<script>
require([
"esri/Map",
"esri/views/MapView",
"esri/widgets/Locate"
], function (Map, MapView, Locate) {
var map = new Map({
basemap: "topo-vector"
});
var view = new MapView({
container: "viewDiv",
map: map,
center: [-56.049, 38.485, 78],
zoom: 3
});
var locateBtn = new Locate({
view: view
});
// Add the locate widget to the top left corner of the view
view.ui.add(locateBtn, {
position: "top-left"
});
view.when(_ => {
const n = document.getElementsByClassName("esri-icon-locate");
if (n && n.length === 1) {
n[0].classList = 'my-svg-icon';
}
});
});
</script>
</head>
<body>
<div id="viewDiv"></div>
</body>
</html>
