Javascript OpenLayers addLayers因TypeError失败
我正在从OpenLayers 3.15.0更新到6.3.1。 调用map.addLayer时,出现以下错误:Javascript OpenLayers addLayers因TypeError失败,javascript,openlayers,Javascript,Openlayers,我正在从OpenLayers 3.15.0更新到6.3.1。 调用map.addLayer时,出现以下错误: Uncaught TypeError:无法读取未定义的属性“ol\u uid”@ ecb://web/java/ol.js:1:23754 以下是其名称的上下文: 函数getMinZoom(){ var-width=map.clientWidth; 返回Math.ceil(Math.LOG2E*Math.log(宽度/256)); } //创建wms图层 函数addWMSLayer(u
Uncaught TypeError:无法读取未定义的属性“ol\u uid”@
ecb://web/java/ol.js:1:23754
以下是其名称的上下文:
函数getMinZoom(){
var-width=map.clientWidth;
返回Math.ceil(Math.LOG2E*Math.log(宽度/256));
}
//创建wms图层
函数addWMSLayer(url、attTxt、attHref、层、格式、服务器、res1、res2、res3、res4){
初始化映射();
//加载wms层的平铺源
var newRes1=编号(getCalcResolutionSrv(res1));
var newRes2=数量(getCalcResolutionSrv(res2));
var newRes3=数量(getCalcResolutionSrv(res3));
var newRes4=编号(getCalcResolutionSrv(res4));
var newWMSSource=new ol.source.TileWMS({
url:url,
参数:{
“层”:层,
“格式”:格式,
},
服务器类型:“mapserver”,
投影:投影
});
var minZoom=getMinZoom();
var newWmsLayer=新建ol.layer.Tile({
范围:范围,,
资料来源:newWMSSource,
minResolution:newRes4,
maxResolution:newRes1,
zIndex:0,
最小缩放:最小缩放
});
wmsResolution.push(编号(newRes1-0.00100));
wmsResolution.push(newRes2);
wmsResolution.push(newRes3);
wmsResolution.push(编号(newRes4+0.00100));
map.addLayer(newWmsLayer);
ECBJS.addNewWMSLayer(url、层、newRes1、newRes2、newRes3、newRes4);
};
该函数与3.15.0中用于调用addLayer的函数相同,但zIndex和minZoom属性除外。在3.15.0版本中,它开始工作
有什么问题吗
更新
我基于CefSharp的MinimalExample创建了一个MinimalExample解决方案。您需要Visual Studio或Rider才能打开它。
当前,在MainWindows.xaml.cs中的函数CallWebSite中对EvaluateScript Async的调用返回
Message=“Uncaught TypeError:无法读取的属性“ol\u uid”
未定义@ecb://web/java/ol.js:1:23754"
成功=错误
我希望它能和你一起回来
Message=“”
成功=正确
映射对象未正确初始化。以下是创建地图的代码:
var map = new ol.Map({
controls: ol.control.defaults().extend([
new ol.control.ScaleLine({
units: 'metric'
})
]).extend([mousePositionControl]),
layers: [filterVector],
overlays: [overlay],
logo: false,
target: 'map',
view: new ol.View({
})
});
它使用带有mousePositionControl的扩展。mousePositionControl定义为:
var mousePositionControl = new ol.control.MousePosition(
{
coordinateFormat: ol.coordinate.createStringXY(1),
projection: 'EPSG:2056',
className: 'custom-mouse-position',
target: document.getElementById('info'),
undefinedHTML: ' '
});
所以它使用了一个投影。投影未正确初始化
var extent = [2420000, 130000, 2900000, 1350000];
var jsLayers = new Object();
if (proj4) {
proj4.defs("EPSG:2056", "+proj=somerc +lat_0=46.95240555555556 +lon_0=7.439583333333333 +k_0=1 +x_0=2600000 +y_0=1200000 +ellps=bessel +towgs84=674.374,15.056,405.346,0,0,0,0 +units=m +no_defs");
};
var projection = ol.proj.get('EPSG:2056');
projection.setExtent(extent);
从我学到的,我可以用
ol.proj.proj4.register(proj4);
帮助投影。现在是:
var extent = [2420000, 130000, 2900000, 1350000];
var jsLayers = new Object();
if (proj4) {
proj4.defs("EPSG:2056", "+proj=somerc +lat_0=46.95240555555556 +lon_0=7.439583333333333 +k_0=1 +x_0=2600000 +y_0=1200000 +ellps=bessel +towgs84=674.374,15.056,405.346,0,0,0,0 +units=m +no_defs");
};
ol.proj.proj4.register(proj4);
var projection = ol.proj.get('EPSG:2056');
projection.setExtent(extent);
此更改后,filterVector丢失,必须在初始化地图之前将覆盖的定义移动到
var filterSource = new ol.source.Vector({ wrapX: false });
var filterVector = new ol.layer.Vector({
source: filterSource,
style: new ol.style.Style({
fill: new ol.style.Fill({
color: 'rgba(255, 255, 255, 0.5)'
}),
stroke: new ol.style.Stroke({
color: '#ffcc33',
width: 2
}),
image: new ol.style.Circle({
radius: 7,
fill: new ol.style.Fill({
color: '#ffcc33'
})
})
})
});
var container = document.getElementById('popup');
var content = document.getElementById('popup-content');
var closer = document.getElementById('popup-closer');
var overlay = new ol.Overlay(({
element: container,
autoPan: true,
autoPanAnimation: {
duration: 250
}
}));
我更新了上的最小示例以反映这些更改。映射对象未正确初始化。以下是创建地图的代码:
