【iClient】Leaflet服务器端专题图，如何设置标签沿线标注？

Answer 1

【解决方法】使用labelExpression，如果多个字段，使用“”“||”连接。贴图 代码参考： themeLabel = new L.supermap.ThemeLabel({ labelExpression:"NAME"+"||"+"SmLength", alongLine: new L.supermap.ThemeLabelAlongLine({ isAlongLine:true, alongLineDirection:L.supermap.AlongLineDirection.NORMAL, }), overlapAvoided:false, smallGeometryLabeled:false }); themeParameters = new L.supermap.ThemeParameters({ themes: [themeLabel], datasetNames: ["Rivers"], dataSourceNames: ["World"] });
