Azure移动服务javascript从插入函数更新
我正在为WindowsPhone8、iOs和android创建一个移动应用程序。我正在使用WindowsAzure来保存一些配置文件应用程序和一些设备信息。我对JavaScript几乎没有什么经验,尽管在我的头撞了一整天的砖墙之后,我想它开始发出咔哒声了。尽管如此,您可能会嘲笑我下面的代码 下面是一个名为Devices的表的insert语句 如果用户ID当前没有任何记录,我将尝试进行正常插入 如果已经有记录,则更新该记录Azure移动服务javascript从插入函数更新,javascript,mobile,azure,Javascript,Mobile,Azure,我正在为WindowsPhone8、iOs和android创建一个移动应用程序。我正在使用WindowsAzure来保存一些配置文件应用程序和一些设备信息。我对JavaScript几乎没有什么经验,尽管在我的头撞了一整天的砖墙之后,我想它开始发出咔哒声了。尽管如此,您可能会嘲笑我下面的代码 下面是一个名为Devices的表的insert语句 如果用户ID当前没有任何记录,我将尝试进行正常插入 如果已经有记录,则更新该记录 function insert(item, user, request)

我想你会想要这样的东西:
function insert(item, user, request) {
item.userId = user.userId;
var deviceTable = tables.getTable('Devices');
deviceTable
.where({
userId: user.userId
}).read({
success: function(results) {
if (results.length > 0) {
//We found a record, update some values in it
results[0].fieldName = X;
//Update it in the DB
deviceTable.update(results[0]);
//Respond to the client
request.respond(200, results[0]);
console.log('updated position ok');
} else {
//Perform the insert in the DB
request.execute();
console.log('Added New Entry',user.userId);
//Reply with 201 (created) and the updated item
request.respond(201, item);
}
}
});
