乡镇、街道使用echart时报错解决，在echart.js中找到函数parseGeoJSON，用下边的将其替换即可

function parseGeoJSON(geoJson, nameProperty) {geoJson = decode(geoJson);return map(filter(geoJson.features, function (featureObj) {// Output of mapshaper may have geometry nullreturn featureObj.geometry && featureObj.properties && (// avoid length error if missing coordinates(featureObj.geometry.coordinates && featureObj.geometry.coordinates.length > 0)// allow GeometryCollection|| (featureObj.geometry.geometries && featureObj.geometry.geometries.length > 0))}), function (featureObj) {var properties = featureObj.properties;var geo = featureObj.geometry;var geometries = [];if (geo.type === 'Polygon') {var coordinates = geo.coordinates;geometries.push({type: 'polygon',// According to the GeoJSON specification.// First must be exterior, and the rest are all interior(holes).exterior: coordinates[0],interiors: coordinates.slice(1)});}if (geo.type === 'MultiPolygon') {var coordinates = geo.coordinates;each(coordinates, function (item) {if (item[0]) {geometries.push({type: 'polygon',exterior: item[0],interiors: item.slice(1)});}});}else if (geo.type === 'GeometryCollection') {var geometries2 = geo.geometries;each(geometries2, function (geo) { // OR      zrUtil.each(geometries2, function (geo) {var coordinates = geo.coordinates;if (geo.type === 'Polygon') { // this is a full copy from abovegeometries.push({type: 'polygon',exterior: coordinates[0],interiors: coordinates.slice(1)});} // end full copy});}var region = new GeoJSONRegion(properties[nameProperty || 'name'], geometries, properties.cp);region.properties = properties;return region;});}

主要修改下边指出的两个部分

return featureObj.geometry && featureObj.properties && (// avoid length error if missing coordinates(featureObj.geometry.coordinates && featureObj.geometry.coordinates.length > 0)// allow GeometryCollection|| (featureObj.geometry.geometries && featureObj.geometry.geometries.length > 0))

else if (geo.type === 'GeometryCollection') {var geometries2 = geo.geometries;each(geometries2, function (geo) { // OR      zrUtil.each(geometries2, function (geo) {var coordinates = geo.coordinates;if (geo.type === 'Polygon') { // this is a full copy from abovegeometries.push({type: 'polygon',exterior: coordinates[0],interiors: coordinates.slice(1)});} // end full copy});}
