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

I have a mpgw where the request is JSON.
I save the content in a context variable with JSON.stringify(json)
The problem is when json contains a emoiji eg \uD83D\uDE0D tha variable no longer will be a string, it will be binary and the emoijis is shown as dots.
I need to use the the content of the variable later to calculate hmac so it has to look exact as the original json.
Is there any way to get around this?
Help wold be much appreciated.

Ok, from your comment I can conclude that it is the Stringify() that messes it up. This is according to the cookbook for escaping (there is a RFC describing this)...
Try adding your own function for stringify() that will handle unicode better:
function JSON_stringify(s, emit_unicode) {
var json = JSON.stringify(s);
return emit_unicode ? json : json.replace(/[\u007f-\uffff]/g,
function(c) {
return '\\u'+('0000'+c.charCodeAt(0).toString(16)).slice(-4);
}
);
}
ctx.setVar('json', JSON_stringify(json, false));
Something like that...
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 want to store the result from a call to a Domino Access Service (DAS) in a localStorage however when I try to convert the result object to a JSON string I get an error.
With DAS you get the result as an Array e.g.:
[
{
"#entryid":"1-CD90722966A36D758025725800726168",
"#noteid":"16B46",
Does anyone know how I get rid of the square brackets or convert the Array quickly to a JSON object?
Here is a snippet of my code:
var REST = "./myREST.xsp/notesView";
$.getJSON(REST,function(data){
if(localStorage){
localStorage.setItem('myCatalog',JSON.stringify(data));
}
});
Brackets are part of the JSON syntax. They indicate that this is an array of objects. And as you point to a view it is very likely that you would get more than one object back (one for each entry in the view).
So if you are only interested in the first element you could do this:
var REST = "./myREST.xsp/notesView";
$.getJSON(REST,function(data){
if(localStorage){
var firstRecord = data[0] || {};
localStorage.setItem('myCatalog',JSON.stringify(firstRecord));
}
});
Otherwise, you would need to define a loop to handle each of the objects :-)

Any built-in ready-to-use solution in Kendo UI to parse JSON data according to schema.model?
Maybe something like kendo.parseData(json, model), which will return array of objects?
I was searching for something like that and couldn't find anything built-in. However, using Model.set apparently uses each field's parse logic, so I ended up writing this function which works pretty good:
function parse(model, json) {
// I initialize the model with the json data as a quick fix since
// setting the id field doesn't seem to work.
var parsed = new model(json);
var fields = Object.keys(model.fields);
for (var i=0; i<fields.length; i++) {
parsed.set(fields[i], json[fields[i]]);
}
return parsed;
}
Where model is the kendo.data.Model definition (or simply datasource.schema.model), and json is the raw object. Using or modifying it to accept and return arrays shouldn't be too hard, but for my use case I only needed a single object to be parsed at a time.
I actually saw your post the day you posted it but did not have the answer. I just needed to solve this problem myself as part of a refactoring. My solution is for DataSources, not for models directly.
kendo.data.DataSource.prototype.parse = function (data) {
return this.reader.data(data);
// Note that the original data will be modified. If that is not what you want, change to the following commented line
// return this.reader.data($.extend({}, data));
}
// ...
someGrid.dataSource.parse(myData);
If you want to do it directly with a model, you will need to look at the DataReader class in kendo.data.js and use a similar logic. Unfortunately, the DataReader takes a schema instead of a model and the part dealing with the model is not extracted in it's own method.
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); });
