I am trying to use Adapter for Push Notification. I followed all steps define in this IBM Worklight Developer site for Push Notification and make a project and its working. Now further i want to send notifications to a specific device. For this worklight give a method getDeviceSubscriptions() which return JSON array containing number of object for each subscribed device.
deviceSubscriptions = userSubscription.getDeviceSubscriptions() ;
the JSON include:
[{
"platform": "",
"eventSourceId": "",
"alias": "",
"token": "",
"userAgent": "",
"device": "",
"applicationId": "",
"options": {}
},
{
"platform": "",
"eventSourceId": "",
"alias": "",
"token": "",
"userAgent": "",
"device": "",
"applicationId": "",
"options": {}
}]
Now i want to get value of key device and token. So how can it can be achieved.
At that time i am using JSON.stringify it return a string but i want to have direct access to device and token. When i used JSON.parse it gives [object , Object] but not display any JSON.
After the JSON parse, use this to point out the key directly
obj[0]["device"]
For all the available node you should use incremental value in place of [0], like
obj[i]["device"];
i++;
Just access the properties using array syntax:
var firstDevice=deviceSubscriptions[0].device;
var secondDevice=deviceSubscriptions[1].device;
etc...
Update
Currently your JSON is not valid, the valid json should be :
{
"items": [
{
"platform": "Google",
"eventSourceId": "PushAdapter.PushEventSource",
"alias": "myPush",
"token": " ",
"userAgent": " ",
"device": " ",
"applicationId": " ",
"options": {}
},
{
"platform": "Google",
"eventSourceId": "PushAdapter.PushEventSource",
"alias": "myPush",
"token": " ",
"userAgent": " ",
"device": " ",
"applicationId": " ",
"options": {}
}
]
}
Parse your json string like :
var data = JSON.parse(yourJsonString);
Now access the device and token properties value like:
var device = data.items[0].device; //give device value of 0th item
var token = data.items[0].token; //give token value of 0th item

The ser function should give whole JSON array present in server to formdt[] and then iterate over it and get every object and convert to JSON and push bioguide to id array,search id from input and match with JSON nested value of each object in the array
nothing happens gives error in console :
_this.formdt is undefined at line 37 (this.fdts.getdt().subscribe(dt=>this.formdt.push=dt))
Given error is pretty explicit : this.formdt is undefined.
You've declared preperty type but haven't initialize it.
So replace formdt:string[] with formdt:string[] = []
I'm having some problems when trying to retrieve values from a JSON response sent via the $.post() method in jQuery. Here is the script:
var clickedName = $('#customerId').val();
$.post("/customer-search", { name: clickedName }).done( function(response) {
var results = $.parseJSON(response);
console.log(results);
$('#account-name').html(results.firstname + ' ' + results.lastname);
$('#email').html(results.email);
$('#telephone').html(results.telephone);
if (results.fax) {
$('#fax').html(results.fax);
} else {
$('#fax').html('n/a');
}
$('#personal').fadeIn();
return false;
});
Just to explain, I'm using twitter typeahead in a Symfony2 project, and basically this script will fire when a name is clicked (selected) from the list after typing. The customer-search URL runs a search of the database as follows:
$q = $request->request->get('name');
$em = $this->getDoctrine()->getManager();
$customer = $em->getRepository('AppBundle:Oc73Customer')->findLikeName($q);
$addresses = $em->getRepository('AppBundle:Oc73Address')->findByCustomerId($customer[0]['customerId']);
$results = array();
$results['customer'] = $customer;
$results['addresses'] = $addresses;
return new Response(json_encode($results));
Which will successfully return a Json encoded response, and the value of 'response' which is printed in the console (as per the jquery above) is:
{
"customer": [{
"firstname": "Mike",
"lastname": "Emerson",
"email": "xxxx#xxxx.co.uk",
"telephone": "01234 5678910",
"fax": null,
"password": "8e1f951c310af4c20e2cd6b68dee506ac685d7ae",
"salt": "e2b9e6ced",
"cart": null,
"wishlist": null,
"newsletter": 0,
"addressId": 84,
"customerGroupId": 1,
"ip": null,
"status": 1,
"approved": 1,
"token": null,
"dateAdded": {
"date": "2016-02-16 12:59:28.000000",
"timezone_type": 3,
"timezone": "Europe/Berlin"
},
"availCredit": null,
"customerId": 75
}],
"addresses": [{}]
}
I am trying to retrieve the customer details by using the method I always use, so to get the firstname, I use results.firstname where results is a parsed JSON string, as written in my jQuery response.
However, all I get from results.firstname is undefined, even when it clearly is defined. So, basically, I'm wondering what I am doing wrong?
Hope someone can shed some light on my problem.
The properties you're trying to access are objects in the customer array, not on the parent object itself. Assuming that the response only ever contains one customer object then you can use result.customer[0], like this:
$.post("/customer-search", { name: clickedName }).done(function(response) {
var results = $.parseJSON(response);
var customer = response.customer[0];
$('#account-name').html(customer.firstname + ' ' + customer.lastname);
$('#email').html(customer.email);
$('#telephone').html(customer.telephone);
$('#fax').html(customer.fax ? customer.fax : 'n/a');
$('#personal').fadeIn();
});
If it's possible that multiple customer objects will be returned in the array the you would need to amend your code to loop through those objects and build the HTML to display them all - without using id attributes.
I was able to access it like "results.customer[0].firstname"
var cus =
{
"customer": [{
"firstname": "Mike",
"lastname": "Emerson",
"email": "xxxx#xxxx.co.uk",
"telephone": "01234 5678910",
"fax": null,
"password": "8e1f951c310af4c20e2cd6b68dee506ac685d7ae",
"salt": "e2b9e6ced",
"cart": null,
"wishlist": null,
"newsletter": 0,
"addressId": 84,
"customerGroupId": 1,
"ip": null,
"status": 1,
"approved": 1,
"token": null,
"dateAdded": {
"date": "2016-02-16 12:59:28.000000",
"timezone_type": 3,
"timezone": "Europe/Berlin"
},
"availCredit": null,
"customerId": 75
}],
"addresses": [{}]
}
alert(cus.customer[0].firstname);
I've figured out how to query for some metadata for example calling this in my query:
<td>" + record['created'].value + "</td> <-- populates some table data
But this comes back undefined which confuses me because the CloudKit dashboard has a value for Created By (as part of the automatic Metadata that is created with each record.)
How do I query for the ID/UUID as well as get the response in a HTML/JS-readable manner?
After fetching one or more records with CloudKit.js you'll notice you get back an Object that looks like this:
{
"recordName": "6E863D3D-5371-4376-A9BA-3B294F480E4E",
"recordType": "Message",
"fields": {
"text": {
"value": "hi",
"type": "STRING"
},
},
"recordChangeTag": "ib461v1s",
"created": {
"timestamp": 1434751588720,
"userRecordName": "_36ed4b61e7a11c9302f851fe25a9b911",
"deviceID": "_2"
},
"modified": {
"timestamp": 1434751588720,
"userRecordName": "_36ed4b61e7a11c9302f851fe25a9b911",
"deviceID": "_2"
}
}
The recordName is a record's unique identifier, and the Object has a created attribute which points to an Object with a timestamp field.
How to get value from [object Object] in javaScript.
i have a json response from php which i pass in javascript .

Look at javascript tutorial
obj['key_name']
JSON objects work as an array. You can access to an element with a key:
obj['Account'] // returns dimts
obj.Account // works also
You should read some tutorial about it, like JSON: What It Is, How It Works, & How to Use It
Please retrive the value as
var jArray = <?php echo json_encode($_SESSION['return'] ); ?>;
var obj = JSON.parse(jArray);
var value=obj.Result;
I have zero experience in php so I don't know what's the resulting object from your first line of code. But assuming jArray is a json object with the structure defined in your question...you access its values as shown below...
jArray.Account;
jArray.DeviceList[0].Device; //access the device property of the first object in the DeviceList array
jArray.DeciveList[0].EventData.StatusCode;

And I want to get pagelocation of the children.
Can anyone tell me how to do this?
Hi
i also want to get indexes from this and then want to get pagelocations of that particular children. Can you tell me how would i do that?
And also when i when i am getting indexes array it is returning me ,, only and not the index nos.
I am using following code for that :
indexes=response.documents.map(function(e){ return e.children.index; })
Thanks & Regards
If you're interested in simply retrieving all the page locations, you can do it using filter:
var locations = [];
json.documents.forEach(function(e,i) {
e.children.forEach(function(e2,i2) {
locations.push(e2.pageLocation);
)}
});
// returns flat array like [item1,item2,item3,item4]
You can get an array of arrays using map:
var locations = [];
var locations = json.documents.map(function(e) {
return e.children.map(function(e2) {
return e2.pageLocation;
});
});
// returns 2-dimensional array like [[item1,item2],[item1,item2]]
Your json response is an appropriate javascript object So you can access all elements of the object like you do as in back end.
here, you have an array of object of the type documents and each document object has array of objects of the type children. so
syntax would be
myjson.documents[0].children[0].pagelocation
( = http://192.168.5.13:8888/ebook/user_content/_ADMIN_/_IMAGES_/HDS_054227~201106290029/image_1.png)
will give you the very first page location..
and so on
