I am new to AngularJS and trying to create a $scope for tracks for later usage
data.json (sample):
[
{
"album": "Album name",
"tracks": [
{
"id": "1",
"title": "songtitle1",
"lyric": "lyrics1"
},
{
"id": "2",
"title": "songtitle2",
"lyric": "lyrics2"
}
]
}
]
Controller
app.controller('lyricsCtrl', function($scope, $http) {
$http.get('data.json')
.then(function(result) {
$scope.albums = result.data;
$scope.tracks = result.data.tracks;
console.log($scope.tracks); //Undefined...
});
});
Why is $scope.tracks undefined?
If your json file is as is:
[
{
"album": "Album name",
"tracks": [
{
"id": "1",
"title": "songtitle1",
"lyric": "lyrics1"
},
{
"id": "2",
"title": "songtitle2",
"lyric": "lyrics2"
}
]
}
]
We have a response of:
data: Array[1]
0: Object
album: "Album name"
tracks: Array[2]
Since data is returned as an array you would handle like any other javascript array and access by index, so you could do a loop or if you know only 1 result is going to be returned you could use the zero index:
$http.get('data.json').then(function(result) {
console.log(result);
// Assign variables
$scope.album = result.data[0].album;
$scope.tracks = result.data[0].tracks;
for (var i = 0, l = $scope.tracks.length; i < l; i++) {
console.log($scope.tracks[i].title);
}
});
result.data is an array,So you must have to use index to access its child like:-
$scope.tracks = result.data[0].tracks;
It should be result.data[0].tracks as data is an array
$scope.tracks = result.data[0].tracks;

Json data returned from my ASP.NET core server with:
JsonConvert.SerializeObject(categories.Select(t => new { id = t.Id.ToString(), text = t.Name.ToLower() }))
Looks:
[
{
"id": "7929d7ad-c7c3-45c5-b749-7633a478d55c",
"text": "apparel"
},
{
"id": "e551cbc2-9069-4c99-a66b-5824ec2610b2",
"text": "electronics"
}]
But I want result like:
{"results":[
{
"id": "7929d7ad-c7c3-45c5-b749-7633a478d55c",
"text": "apparel"
},
{
"id": "e551cbc2-9069-4c99-a66b-5824ec2610b2",
"text": "electronics"
}]}
for select2. How can I achieve that?
try this
JsonConvert.SerializeObject( new {
results = categories.Select(t => new { id = t.Id.ToString(), text = t.Name.ToLower() })
} );
I want to transform my data from one json structure to another. What is the best way to do it?
Here is my original resource (customer) structure is:
{
"id": "123",
"data": {
"name": "john doe",
"status": "active",
"contacts": [
{
"email": "john#email.com"
},
{
"phone": "12233333"
}
]
}
}
I want to change it to:
{
"id": "123",
"name": "john doe",
"status": "active",
"contacts": [
{
"email": "john#email.com"
},
{
"phone": "12233333"
}
]
}
Keeping in mind that I might have an array of resources(customers) being returned in GET /customers cases. I want to change that to an array of new data type.
If customer object is array of object then below will help you to get desire format result
var result = customerObj.map(x => {
return {
id: x.id,
name: x.data.name,
status: x.data.status,
contacts: x.data.contacts
};
});
here I have used Object.assign() it will be helpful to you
var arr={
"id": "123",
"data": {
"name": "john doe",
"status": "active",
"contacts": [
{
"email": "john#email.com"
},
{
"phone": "12233333"
}
]
}
}
arr=Object.assign(arr,arr.data);
delete arr['data'];
console.log(arr);
You have to Json.parse the json into variable, and then loop through the array of objects, changes the object to the new format, and then JSON.stringify the array back to json.
Example code
function formatter(oldFormat) {
Object.assign(oldFormat, oldFormat.data);
delete oldFormat.data;
}
let parsedData = JSON.parse(Oldjson);
//Take care for array of results or single result
if (parsedData instanceof Array) {
parsedData.map(customer => formtter(customer));
} else {
formatter(parsedData);
}
let newJson = JSON.stringify(parsedData);
console.log(newJson);
Edit
I made the formatter function cleaner by using Kalaiselvan A code
I'm getting below JSON result from a PHP page using ajax request. I tried a lot to get the desired result. I have done below approach but still unable to get as expected.
{
"search": {
"entry": [
{
"attribute": [
{
"name": "title",
"value": [
"Mr."
]
},
{
"name": "mail",
"value": [
"kiran#gmail.com",
"Kiran#yahoo.com",
"kiran#hotmail.com"
]
}
]
}
]
}
}
I have tried the following search to get the value using Defiant.js
success: function (data) {
var xx=JSON.stringify(data);
// var got = $.each(data.search.entry[0].attribute, function (i, v) {
// return v;
//
// });
alert(xx);
var z=JSON.search( xx, '//*[name="title"]/value[1]' );
alert(z);
},
How would I can get results like title='Mr' or mail='kiran#gmail.com'.
Why you need regex solution if your json has proper structure. I have seen your code and json and it seems that you need first index value for title and mail. see following function which can search both title and mail.
var arrt = ' {"search": {"entry": [ {"attribute": [ {"name": "title","value": [ "Mr."] }, {"name": "mail","value": [ "kiran#gmail.com", "Kiran#yahoo.com", "kiran#hotmail.com"] }] }] }}';
SearchMyWordTT(arrt,"title");
//SearchMyWordTT(arrt,"mail");
function SearchMyWordTT(arr,index){
arr = JSON.parse(arr);
for(var i=0;i< arr["search"]["entry"][0]['attribute'].length;i++){
if(typeof (arr["search"]["entry"][0]['attribute'][i]['name']) !="undefined" && arr["search"]["entry"][0]['attribute'][i]['name'] == index)
retIn = arr["search"]["entry"][0]['attribute'][i]['value'][0];
}
return retIn;
}
I am using AngularJS with RESTAPI, I am able to get the customers data sent from server in a JSON format. My Angular code snippet as below:
app.factory("services", ['$http', function($http) {
var serviceBase = '/api/album';
var obj = {};
obj.getCustomers = function(){
return $http.get(serviceBase);
};
return obj;
}]);
app.controller('listCtrl', function ($scope, services) {
services.getCustomers().then(function(data){
alert(JSON.stringify(data.data));
$scope.customers = data.data;
});
});
Here is my JSON data:
{
"data": [
{
"id": "1",
"artist": "Gotye75",
"title": "Making Mirrors7"
},
{
"id": "100",
"artist": "ytttt5",
"title": "1231"
},
{
"id": "101",
"artist": "65",
"title": "565444555"
},
{
"id": "102",
"artist": "6",
"title": "6"
},
{
"id": "103",
"artist": "y",
"title": "yy"
},
{
"id": "104",
"artist": "ty",
"title": "yt"
},
{
"id": "109",
"artist": "ytrer",
"title": "yt"
}
]
}
I am able to display the JSON data in table if my JSON does not contain the "data" hear. However if my jSON data comes with "data" header, it is unable to display. I am asking, what are the solution in Angular to parse the JSON object.
For example if it is in BackboneJS, i can simply do
parse: function (response) {
//alert(JSON.stringify(response.data));
return response.data;
}
How can i do it in Angular?
$http resolves its promises with a response object. The data is accessed via the response object's data property. So to get to the array, you'd have to use
$scope.customers = data.data.data;
$http's promise is enhanced with a .success() convenience method which unwraps the response object...
services.getCustomers().success(function(data){
alert(JSON.stringify(data.data));
$scope.customers = data.data;
});
I solved it by
app.controller('listCtrl', function ($scope, services) {
services.getCustomers().then(function(data){
//notice that i added the third data
$scope.customers = data.data.data;
});
});
I am using loopjs tokeninput in a View. In this scenario I need to prePopulate the control with AdminNames for a given Distributor.
Code Follows :
$.getJSON("#Url.Action("SearchCMSAdmins")", function (data) {
var json=eval("("+data+")"); //doesnt work
var json = {
"users": [
eval("("+data+")") //need help in this part
]
}
});
$("#DistributorCMSAdmin").tokenInput("#Url.Action("SearchWithName")", {
theme: "facebook",
preventDuplicates: true,
prePopulate: json.users
});
There is successful return of json values to the below function. I need the json in the below format:
var json = {
"users":
[
{ "id": "1", "name": "USER1" },
{ "id": "2", "name": "USER2" },
{ "id": "3", "name": "USER3" }
]
}
