1.要素圖層服務地址
http://192.168.120.19:6080/arcgis/rest/services/FeatureLayer/FeatureServer/2
2.截圖效果
3. 有效參數 Object IDs，接下來僅僅對該參數進行傳值即可。
4.完整代碼如下：

var featureAttributes = results.features[i].attributes;
for (var attr in featureAttributes) {

}
resultItems.push("<br>");
}
dom.byId("info").innerHTML = resultItems.join("");
}
});

<body>
查詢要素信息:
<input type="text" id="ids" value="1">
<input id="execute" type="button" value="Get Details">
<br />
<br />
<div id="info" style="padding:5px; margin:5px; background-color:#eee;">
</div>
</body>
</html>
