所以我的openlayers实现的背景似乎被压扁成垂直条纹.奇怪的是,它并不总是这样,但即使我把所有的改变都保留在我知道它正在工作的地步,它仍然是破碎的.这让我想知道瓦片资产的交付方式是否有变化.我已经尝试使用osm和wms层之间切换,没有任何改变,任何帮助将不胜感激.
以下是相关代码：
initMap: function() {
var view = this;
var map = this.map = new OpenLayers.Map();
map.render(this.$map[0]);
var wmsLayer = new OpenLayers.Layer.WMS( "OpenLayers WMS","http://vmap0.tiles.osgeo.org/wms/vmap0?",{layers: 'basic'});
var osmLayer = new OpenLayers.Layer.OSM();
this.layers = {
point: new OpenLayers.Layer.Vector("Point Layer"),line: new OpenLayers.Layer.Vector("Line Layer"),polygon: new OpenLayers.Layer.Vector("Polygon Layer")
};
this.setValue(this.value);
map.addLayers([this.layers.point,this.layers.line,this.layers.polygon,osmLayer]);
drawControls = {
point: new OpenLayers.Control.DrawFeature(this.layers.point,OpenLayers.Handler.Point),line: new OpenLayers.Control.DrawFeature(this.layers.line,OpenLayers.Handler.Path),polygon: new OpenLayers.Control.DrawFeature(this.layers.polygon,OpenLayers.Handler.Polygon)
};
this.layers[this.layerType].events.on({'sketchcomplete': function(feature) {
if (!view.multiple) {
// deactivate polygon layer once a polygon has been added
drawControls[view.layerType].deactivate();
}
}});
for(var key in drawControls) {
map.addControl(drawControls[key]);
}
if (this.layers[this.layerType].features.length) {
var bounds = this.layers[this.layerType].getDataExtent();
var zoom = this.layers[this.layerType].getZoomForExtent(bounds);
var lon = (bounds.top - bounds.bottom) / 2;
var lat = (bounds.right - bounds.left) / 2;
map.setCenter(new OpenLayers.LonLat(lon,lat),3);
map.zoomToExtent(bounds);
if (view.multiple) {
drawControls[view.layerType].activate();
}
} else {
map.setCenter(new OpenLayers.LonLat(-11174482.03751,4861394.9982606),4);
drawControls[view.layerType].activate();
}
this.$('.clear').click(function(e) {
e.preventDefault();
view.layers[view.layerType].destroyFeatures();
drawControls[view.layerType].activate();
});
},
这是输出：
