如何使用Javascript SDK调用带有参数的云代码函数

我知道在iOS sdk中我可以这样做

[PFCloud callFunctionInBackground:@"email" withParameters:@{@"param1": @"quantity1, @"param2": @"quantity2} block:^(NSString *result, NSError *error) {
    if (error) {
        //error
    } else {
        // make sure the set the email sent flag on the object
        NSLog(@"result :%@", result);
    }
}];

---

但是如何使用Javascript函数来实现这一点呢

Parse.Cloud.run("email", { param1:"quantity1", param2:"quantity2" }).then(function(result) {
    // make sure the set the email sent flag on the object
    console.log("result :" + JSON.stringify(result))
}, function(error) {
    // error
});

使用下面的代码可以完美地工作

NSDictionary *param = [[NSDictionary alloc] initWithObjectsAndKeys:@"A",@"param1",@"B",@"param2", nil];
    [PFCloud callFunctionInBackground:@"email" withParameters:param block:^(id object, NSError *error)
    {

    }];

NSDictionary *param = [[NSDictionary alloc] initWithObjectsAndKeys:@"A",@"param1",@"B",@"param2", nil];
    [PFCloud callFunctionInBackground:@"email" withParameters:param block:^(id object, NSError *error)
    {

    }];
