類型 說明 dataChanged Boolean指示圖層的數據是否已更改。
例子:
// listen to layer's refresh event to fetch the attachments // for the updated features. layer.on("refresh", function(event){ if (event.dataChanged){ const query = layer.createQuery(); layer.queryObjectIds(query).then(function (objectIds) { let attachmentQuery = { objectIds: objectIds, definitionExpression: layer.definitionExpression, attachmentTypes: ["image/jpeg"] }; layer.queryAttachments(attachmentQuery).then(function (attachments) { attachmentQuery.objectIds.forEach(function (objectId) { if (attachments[objectId]) { // process the updated attachments let attachment = attachments[objectId]; } }); }) .catch(function (error) { console.log("attachment query error", error); }); }); } });
