How to get the json files data in a specific order? - javascript

I parsed 3 different json files to an html page using AngularJS.
Here's my code:
Factory code
app.factory('myapp', ['$http', function($http) {
function getLists() {
var tab = ['url1', 'url2', 'url3'];
var list = [];
for(i = 0; i < tab.length; i++) {
$http.get(tab[i])
.then(function(res) {
list.push(res.data);
});
}
return list;
}
return {
getLists: getLists
};
]);
What I want is to display the data of the different files by gender (male/female) That depends on the name 'nm'. The names of girls then the names of boys .The data of the first url in the first line , the second one in the second line , etc...
Html code:
<tr ng-repeat="d in list">
<td>{{d.nm}}</td>
<td>{{d.cty}}</td>
<td>{{d.hse}}</td>
<td>{{d.yrs}}</td>
</tr>
I thinked about doing an if test in the controller where I specify the names of girls and the name of boys but it's not really obvious to me how to do that
what should I do?

You can give ID for the Name. Then Give orderBy for the id' of the name.
<tr ng-repeat="d in list| orderBy:ID">
</tr>

Angular has orderBy directive and you can use it inside ng-repeat to sort your data.
Try like that;
Replace genderField and nameField with your propery names.
<tr ng-repeat="d in list| orderBy:['genderField','nameField']">
<td>{{d.nm}}</td>
<td>{{d.cty}}</td>
<td>{{d.hse}}</td>
<td>{{d.yrs}}</td>
</tr>
Reference

I have created an id as #tommoc suggested me in a comment and that worked :)

How to stop inner ng-repeat in a nested loop from updating when the array changes

So I have an array of events and each event has teams participating. these two object are related but neither is a property of the other.
What I want to do is loop through every event and display every team participating in it. I try to do this using nested ng-repeats. My problem is the inner ng-repeats only displays once the outer ng-repeat has finished executing. Meaning that what ever team participated in the last event processed will be displayed in every table.
In my controller I have an array of teams and I update that array every time I get a new event, and an array of every
here is my repeating table
<div ng-repeat="event in events" ng-init="getTeams(event.eventId)">
<div class="active title">Teams in {{event.eventName}} #{{event.eventId}}</div>
<table>
<thead>
<tr>
<th>Name</th>
<th>Sport</th>
<th>Motto</th>
<th>W-L-D</th>
<th>Description</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="team in teams">
<td>{{team.teamName}}</td>
<td>{{team.teamSport}}</td>
<td>{{team.teamMotto}}</td>
<td>{{team.win}}- {{team.lose}} - {{team.draw}}</td>
<td>{{team.teamDescription}}</td>
</tr>
</tbody>
</table>
</div>
and here is my controller
(function(){
angular
.module('foo')
.controller('EventController', function ($scope, $location, EventService) {
$scope.events = [];
$scope.targetEvent = {};
$scope.teams = [];
EventService.getEvents()
.then(function(events){
$scope.events = events;
});
$scope.getTeams = function(currEventId){
EventService.getTeams(currEventId)
.then(function(eventTeams) {
$scope.teams = eventTeams;
})
}
})()
I have tried using track by but tracking it by the eventId or teamId does not seem to work. Thank you in advance for your help
Although you have creating teams variable each time. It would be global and single for all events as per your current implementation. I don't think so you should be using ng-init here, rather perform that operation inside controller itself by looping over events.
EventService.getEvents().then(function(events){
$scope.events = events;
//loop over each event.
events.forEach(function(event){
EventService.getTeams(currEventId)
.then(function(eventTeams) {
//placed specific teams on event level
event.teams = eventTeams;
})
})
});
Then you just need to change the inner ng-repeat to below and remove ng-init
<tr ng-repeat="team in event.teams">

How to process a json and return a new json

What I'm trying to make is an angular app that reads in a json file and displays them, and allows users to edit the json file using html controls. Then, the user can create a new json object based on their selections and display it.
Here is a picture to help describe what I'm trying to do:
So, the user sees this, they make certain selections, e.g. lock them or delete them, then they hit create, and a new json file is returned based on which objects they have chosen to lock or delete.
At the moment I just have a standard angular app which gets and displays the json:
var app = angular.module('myApp', []);
app.controller('customersCtrl', function($scope, $http) {
$http.get("http://www.w3schools.com/angular/customers.php").then(function (response) {
$scope.myData = response.data.records;
});
$scope.createJson = function(){
// Create new json file
};
});
The body of my html/my angular app looks like this at the moment:
<div ng-app="myApp" ng-controller="customersCtrl">
<table>
<tr ng-repeat="x in myData">
<td>{{ x.Name }}</td>
<td>{{ x.City }}</td>
<td>{{ x.Country }}</td>
<td><input type="checkbox" name="lock" value="{{x.Name}}"></td>
<td><input type="checkbox" name="delete" value="{{x.Name}}"></td>
</tr>
</table>
<button ng-click="createJson()">Create</button>
</div>
Baiscally, I'm not sure if my approach is correct at the moment, and if it is, I don't really know what my next step is.
P.S. this is just test data I am using for the sake of learning/testing, it is not my data, I got it from: http://www.w3schools.com/angular/customers.php
You can try
JSON.stringify($scope.myData)
or
angular.toJson($scope.myData)
this will give you string representation of your data object. The rest is up to you, you may assign it to textarea, post it back to server (in this case, you most likely won't even need to encode it before) etc.
You should use
<td><input type="checkbox" name="lock" value="{{x.Name}}"></td>
<td><input type="checkbox" name="delete" value="{{x.Name}}"></td>
as
<td><input type="checkbox" name="lock" ng-model="x.Name"></td>
<td><input type="checkbox" name="delete" ng-model="x.Name"></td>
(Actually I didn't understand why you use string in checkbox. It should be boolean value).
By this way any change will change your $scope.myData.
On create you should take info from user and create a new JsonObject like
var newObject = {
Name: 'Name Surname',
City: 'City',
Country: 'Country'
}
And add this to your myData with;
$scope.myData.push(newObject);
I ended up creating an appropriate solution by simply creating a new and empty JSON object:
var newJson = [];
and populating it by looping through my original one and using array.push() to add the selected entries:
for (var person in $scope.myData){
if($scope.myData[person].Delete === false || $scope.myData[person].Lock === true){
newJson.push($scope.myData[person])
}
}

ng repeat array in array

I am trying to repeat a child array of a multidimensional array with ng repeat in Angular.
My json object is this:
$scope.items = [{ "id":1,
"BasisA":"1",
"Basis":true,
"personSex":"m",
"isCollapsed":false,
"name":"Mark Polos",
"age":"1955",
"results":[{"1000":{"company_name":"***","model":"***","modelname":"***","pr":222,"rating":4.5,"priority":9,"matching":1},
"1001":{"company_name":"***","model":"***","modelname":"***","pr":228.7,"rating":5.7,"priority":7,"matching":2},
"1002":{"company_name":"***","model":"***","modelname":"***","pr":241.7,"rating":1.9,"priority":4,"matching":3}
}]
}]
Itried somthing like this:
... data-ng-repeat="item in items">
And then in the table of this child:
<tr data-ng-repeat="i in item | orderBy:'insItem.pr'">
It doesn't look like that results property is actually an "array." If that's just a typo in your example, then disregard. If not ... read on.
It looks like an array with a single item, and that Item is a set of properties which are, in turn, objects. In other words, you would reference the property "pr" for the result named "1000" by with code that looks like item.results[0]["1000"].pr NOT with code that looks the way your ng-repeat is expecting(item.results[0].pr).
Can you transform your items when you get them so that results is a true array?
OR - can you use a function inside of your controller that returns the array you are looking for?
View Code:
<... data-ng-repeat="result in resultsFromItem(item)" >
Controller Code:
$scope.resultsFromItem = function (item) {
if(item==undefined || item.results==undefined || item.results.length==0) {
return [];
}
var myResults = [];
for (var key in item.results[0]) {
if(item.results[0].hasOwnProperty(key)) {
myResults.push(item.results[0][key]);
}
}
return myResults;
}
You might even decide to hang that "transformed" results object off each item object (so you only have to go through the transform one time) if you wanted to.
You should access to the results field:
... data-ng-repeat="item in items">
<tr data-ng-repeat="i in item.results">
Since the nested array is in the results property of the main object.
I used three nested ng-repeat directives to get this rolling :-) The third ng-repeat uses ng-repeat="(key, value) in result" functionality to display all result object keys and values, which I got working with the help of this answer on how to iterate over keys and values in ng-repeat. The orderBy: part isn't yet working (if someone knows how to implement that then any help is welcomed).
<ul>
<li ng-repeat="item in items">
id: {{item.id}}, name: {{item.name}}, age: {{item.age}}, results:
<table>
<tr ng-repeat="result in item.results">
<td>
<table style="border: 1px solid black;">
<tr ng-repeat="(key, value) in result | orderBy: value.pr">
<td> {{key}} </td> <td> {{ value }} </td>
</tr>
</table>
</td>
</table>
</li>
</ul>

AngularJs. Problems with ng-repeat

I'm having two tables witch renders data trough angularJs, coming from 2 c#-methods.
The tables are structured almost exactly the same. The first one below is used as I searchfield and the other one is used basiclly to render names.
My problem is that the first one works perfect, but the other one does not. And I don't see the problem. Any help would be appreciated. // Thanks!
Here are my two tables. (the first one is working)
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.3.0-beta.18/angular.min.js"></script>
<div ng-app="searchApp">
<div ng-controller="searchController">
#*first table works*#
<span style="color: white">Search:</span> <input data-ng-click="myFunction()" ng-model="searchText">
<table style="color: white" id="searchTextResults">
<tr><th>Name</th></tr>
<tr ng-show="!!searchText.length != 0" ng-repeat="friend in friends | filter:searchText">
<td data-id="{{friend.id}}" data-ng-click="SendFriendRequest(friend.id)">{{friend.id.replace("RavenUsers/","")}}</td>
</tr>
</table>
#*Does not work*#
<input type="button" value="Get friends requests" data-ng-click="GetFriendRequests()">
<table style="color: white">
<tr><th>Friend requests</th></tr>
<tr ng-repeat="friendRequest in friendRequests">
<td data-id="{{friendRequest.UserWhoWantsToAddYou}}" data-ng-click="acceptUserRequest(friendRequest.UserWhoWantsToAddYou)">{{friendRequest.UserWhoWantsToAddYou}}</td>
</tr>
</table>
</div>
</div>
HERE IS MY SCRIPT
<script>
var App = angular.module('searchApp', []);
App.controller('searchController', function ($scope, $http) {
//Get all users to the seachFunction
$scope.myFunction = function () {
var result = $http.get("/Home/GetAllUsersExeptCurrentUser");
result.success(function (data) {
$scope.friends = data;
});
};
//Get friendRequests from other users
$scope.GetFriendRequests = function () {
var result = $http.get("/Home/GetFriendRequests");
result.success(function (data) {
$scope.friendRequests = data;
});
};
});
</script>
The first script-function called myFunction works perfect and the data coming from my c#-method looks like this:
[{"id":"RavenUsers/One"},{"id":"RavenUsers/Two"},{"id":"RavenUsers/Three"}]
The second script-function called GetFriendRequests does not work, and as far as I can see there is no difference between this data passed into here than the data passed into myFunction:
[{"userWhoWantsToAddYou":"RavenUsers/Ten"},{"userWhoWantsToAddYou":"RavenUsers/Eleven"}]
I'd suggest you use then instead of success because $http returns a promise.
If your table doesn't "render" then put a breakpoint inside success function, console.log() the data or check friendRequests inside your HTML template, e.g. using <div>{{ friendRequests | json }}</div>, to ensure you actually got data from response.
Now you do not handle exceptions at all.
Example:
result.then(function(data) {
console.log('got data')
},function(error) {
console.log('oh noes :( !');
});
Related plunker here http://plnkr.co/edit/KzY8A3
It would be helpful if you either (a) provided a plunker to your code or (b) provided the error message.
ng-repeat requires a uniquificator on each item in the repeat, which defaults to item.id. If you don't have an id field on the item, you'll need to tell angular what field to use.
https://docs.angularjs.org/api/ng/directive/ngRepeat
So I'd suggest changing
<tr ng-repeat="friendRequest in friendRequests">
to
<tr ng-repeat="friendRequest in friendRequests track by userWhoWantsToAddYou">
and see if that works.

AngularJS - ng-repeat Showing single records Multiple Times

I am working with AngularJS. I am getting strange behavior from ng-repeat. I have a controller which returns me the data to ng-repeat such as:
.....
//My other JS Functions
.....
var app = angular.module('main', ['ngTable']).
controller('DemoCtrl', function($scope, ngTableParams) {
var data = [
//data in JSON form
];
$scope.tableParams = new ngTableParams({
page: 1, // show first page
count: 5 // count per page
}, {
total:data.length,
getData: function($defer, params) {
var slicedData = data.slice((params.page() - 1) * params.count(), params.page() * params.count());
alert(slicedData.length);
console.log(slicedData);
$defer.resolve(slicedData);
}
});
})
So, now one thing to note here that I am getting expected data after slicing it that I am passing to:
$defer.resolve(slicedData);
So, no issue seems here as it passes desired data.
Now, I have ng-repeat where I show data in form of tables such as:
<table ng-table="tableParams" class="table ng-table-responsive">
<tr ng-repeat="d in $data">
<td data-title="Name">
{{d.id}}
</td>
<td data-title="length">{{$data.length}}</td>
<td data-title="Age">
{{d.ciscoID}}
</td>
</tr>
</table>
So, here I am getting accurate length that is 5. But the number of records(rows) shown are 25(5*5) that each row is shown five times. Similarly, if I set the count to 10, then each record will be shown ten times.
I am unable to understand this scenario as
<td data-title="length">{{$data.length}}</td>
gives me the correct length then it should iterate correctly too.
P.S. My getData() method in the controller is called twice don't know why?
Any help/guidance regarding this will be highly appreciated. Thanks :-)
This Issue was fixed just by replacing the 'JS' and 'CSS' files with the latest ones.
