supermap构件的查询

1.后台搭建服务（后补）

2. 主要代码

var sql = {
    "getFeatureMode": "SQL",
    "datasetNames": ["***:***"],  //这里从后台查对应的服务
    "maxFeatures": 1000,
    "queryParameter": {
        "sortClause": null,
        "ids": null,
        "name": null,
        "attributeFilter": "SmID<10",  //根据过滤返回的数据
        "groupClause": null,
        "linkItems": null,
        "joinItems": null,
        "fields": null
    }
}

const result = post(`。。。服务地址/featureResults.json?returnContent=true`, sql)

for(var i=0;i<result.features.length;i++){
    console.log(result.features[i]);
}
