I have a JSON object returned in my console, and I want to display those data named "offers".
the JSON object is returned like that :
I tried to display my JSON Object data with :
console.log(JSON.stringify(data));
The thing is, it says that "data is not defined"
Does anyone know what happens ? :)
You should add full path to element of json, for example if your json looks like:
var json = {"par":22, "par2":555, "elems":[{"attr1":53, "attr2":99}] };
and if you want to get attr1 value, you should do something like this:
console.log(json.elems[0].attr1); // 53
so in your case that could be something like:
variableName.result.data.offers //variableName is variable that your "consoling"
Method JSON.stringify doesn't get yout specified value from JSON structure, it's converts JSON object to string.
console.dir provides a good representation of object than console.log().U can try with both
console.log(result.data.offers[0]);
console.dir(result.data.offers[0]);

so i have this data which is outputted from stringify(doc)
{
"id": "8467fdae-c38c-4b6e-9492-807d7c9eb97e",
"message": "send to nodejs"
}
but im not sure how can i go ahead in getting a single value from it, e.g message. Any help would be appreciated as ive tried different methods and they seem to not be working
After you use stringify method the value you have is string.
So You can not get single property from it, except you convert it become object again and get property it. Like this:
object = {
"id": "8467fdae-c38c-4b6e-9492-807d7c9eb97e",
"message": "send to nodejs"
};
// JSON string is value which you get after use Stringify method
jsonString = JSON.stringify(object);
// Convert jsonString to object again and get message property
message = JSON.parse(jsonString).message
stringify() will convert json to string.
Before running stringify(), doc is already json and you can get message by doc.message.
after running stringify(), the result will be string, if you want to get json back, you can use JSON.parse()
I'm using a service to load my form data into an array in my angular2 app.
The data is stored like this:
arr = []
arr.push({title:name})
When I do a console.log(arr), it is shown as Object. What I need is to see it
as [ { 'title':name } ]. How can I achieve that?
you may use below,
JSON.stringify({ data: arr}, null, 4);
this will nicely format your data with indentation.
To print out readable information. You can use console.table() which is much easier to read than JSON:
console.table(data);
This function takes one mandatory argument data, which must be an array or an object, and one additional optional parameter columns.
It logs data as a table. Each element in the array (or enumerable property if data is an object) will be a row in the table
Example:
first convert your JSON string to Object using .parse() method and then you can print it in console using console.table('parsed sring goes here').
e.g.
const data = JSON.parse(jsonString);
console.table(data);
Please try using the JSON Pipe operator in the HTML file. As the JSON info was needed only for debugging purposes, this method was suitable for me. Sample given below:
<p>{{arr | json}}</p>
You could log each element of the array separately
arr.forEach(function(e){console.log(e)});
Since your array has just one element, this is the same as logging {'title':name}
you can print any object
console.log(this.anyObject);
when you write
console.log('any object' + this.anyObject);
this will print
any object [object Object]
I am trying to do the following:
render [assignedSchol:assignedSchol,scholType:scholType] as JSON
assignedSchol is an object, and scholType is just a value. I get a "No map entry allowed at this place error". any help?
When you use one liner like you did you must put the conversion in braces like this:
render ( [assignedSchol:assignedSchol,scholType:scholType] as JSON )
But I think the above code returns json data as plain text format so I usually prefer doing it this way:
render(contentType: "text/json") {
[assignedSchol:assignedSchol,scholType:scholType]
}
Which gives me json data with response type json.
This should work:
render(contentType: "application/json") {[assignedSchol:assignedSchol,scholType:scholType]}
my JSON response is as given below
JSON response is
{"code":201,"message":[["TEST Action","NA","30-11--2011"],["TEST Action 2","NA","30-11--2011"]]}.
i want to take the data correspond to 'message'.i used JSON Array.and got response as
JSON array response is
[["TEST Action","NA","30-11--2011"],["TEST Action 2","NA","30-11--2011"]].
Now how can i access each array in that?
You should expand on what you have done, what language you are using, etc. Normally, you should be able to index into the array with the standard notation. In python for example you can do something along the lines of json_data["message"][0] to access the first array and json_data["message"][1] to access the second.
something like :
var d = JSON.parse('{"code":201,"message":[["TEST Action","NA","30-11--2011"],["TEST Action 2","NA","30-11--2011"]]}')
and then you can access each array in message part as :
d.message.forEach(function(obj) { console.log(obj); });
this is my json format
({"message":{"success":true,"result":[{"lead_no":"LEA13","lastname":"Developer","firstname":"PHP","company":"Dummies","email":"nandhajj#gmail.com","id":"10x132"},{"lead_no":"LEA14","lastname":"Venu","firstname":"Yatagiri","company":"Rsalesarm","email":"veve#jajs.com","id":"10x133"},{"lead_no":"LEA4","lastname":"Jones","firstname":"Barbara","company":"Vtigercrm inc","email":"barbara_jones#company.com","id":"10x35"},{"lead_no":"LEA1","lastname":"Smith","firstname":"Mary","company":"Vtiger","email":"mary_smith#company.com","id":"10x32"}]}})
i am trying to retrieve the whole json result values using the following snippet
if (xmlHttp.readyState==4)
{
alert(xmlHttp.status);
if(xmlHttp.status==200)
{
alert("hi");
var jsondata=eval("("+xmlHttp.responseText+")") //retrieve result as an JavaScript object
jsonOutput=jsondata.result;
alert(jsonOutput);
InitializeLeadStorage()
}
}
my alert (hi ) is displayed but the alert(jsonOutput); is undefined , please help me if you could find any mistake
jsonOutput = jsondata.message.result;
result lives on message - it is not a top-level item in the JSON. With things like this, console.log() the JSON and you can check the path to the bit you want.
Also
your variable is global
there are better ways of parsing your JSON. If you don't care about old IEs, you can use the ECMA5 JSON.parse(), else use jQuery or another third-party utility for this
