Aradhya4
Reena5

There are some minor mistakes in your code.
1. initialization for $scope.emailNames was missing.
2. console.log statement was in loop.
3. Instead of appending += to the string, you were overriding it =.
angular.module("myapp", []).controller('MailCtrls', function($scope) {
$scope.employee = [{
id: 1,
name: 'Anil Singh1',
age: 30,
web: 'www.code-sample.com'
}, {
id: 2,
name: 'Sunil Singh2',
age: 25,
web: 'www.code-sample.com'
}, {
id: 3,
name: 'Sushil3',
age: 20,
web: 'www.code-sample.com'
}, {
id: 4,
name: 'Aradhya4',
age: 2,
web: 'www.code-sample.com'
}, {
id: 5,
name: 'Reena5',
age: 25,
web: 'www.code-sample.com'
}];
$scope.GetData = function() {
$scope.emailNames = "Email=";
for (var i = 0; i < $scope.employee.length; i++) {
var abc = $scope.employee[i];
if (abc.name != null) {
$scope.emailNames += abc.name + ",";
}
}
console.log($scope.emailNames.substring(0,$scope.emailNames.length-1));
}
})
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myapp" ng-controller="MailCtrls" ng-init="GetData()">

How to manipulate the object inside the array using javascript?

var arr = [
{ id: 1, name: 'Ahmed Malick', school: 'TEWGS' },
{ id: 2, name: 'Tehmeed Anwar', school: 'DGS' },
{ id: 3, name: 'Azhar Yameen', school: 'DGS' }
]
I want this output:
The student name is his id is and he studies in
Can you please show me what kind of output you expect. Then i will try to solve it.
I'm not sure if this is what you want
var arr = [
{ id: 1, name: "Ahmed Malick", school: "TEWGS" },
{ id: 2, name: "Tehmeed Anwar", school: "DGS" },
{ id: 3, name: "Azhar Yameen", school: "DGS" },
];
arr.map((student) => {
return `Name: ${student.name}, id: ${student.id}, he studies in: ${student.school}`;
}).forEach((output) => {
console.log(output);
});
If you want it in the DOM do this
let html = arr.map((student) => {
return `<p><strong>Name</strong>: ${student.name}, <strong>id</strong>: ${student.id},<strong> he studies in</strong> ${student.school}</p>`;
}).join("")
document.createElement("div").innerHTML = html

How to filter array based on id in angularJS

i have multiple data for one id , i want filter my data like this
$scope.mpArray =[
{ Id: 1, Name: Madhu, Address: Upal },
{ Id: 1, Name: Chandu, Address: Upal },
{ Id: 2, Name: Srinu, Address: Kphb },
{ Id: 2, Name: Vijay, Address: kphb },
{ Id: 3, Name: Ajay, Address: Banglore },
{ Id: 3, Name: Narsi, Address: Banglore },
{ Id: 3, Name: Peter, Address: Banglore },
];
i want to filter my array like this
var FilterArray = [
{ Id: 1,Madhu, Chandu},
{ Id: 2, Srinu, Vijay},
{ Id: 3, Ajay, Narsi, Peter},
];
At first you need to change your FilterArray to
[
{
"Id": 1,
"Name": [
"Madhu",
"Chandu"
]
},
{
"Id": 2,
"Name": [
"Srinu",
"Vijay"
]
},
{
"Id": 3,
"Name": [
"Ajay",
"Narsi",
"Peter"
]
}
]
Notice that name is an array. The FilterArray of your question
var FilterArray = [
{ Id: 1,Madhu, Chandu},
{ Id: 2, Srinu, Vijay},
{ Id: 3, Ajay, Narsi, Peter},
];
Do not contain a valid JSON object inside the array so you need to change the structure to the one where add a new key Name in the JSON object of FilterArray as like the first structure above. Then the below code works great.
$(document).ready(function(){
var myArray =[
{ Id: 1, Name: "Madhu", Address: "Upal" },
{ Id: 1, Name: "Chandu", Address: "Upal" },
{ Id: 2, Name: "Srinu", Address: "Kphb" },
{ Id: 2, Name: "Vijay", Address: "kphb" },
{ Id: 3, Name: "Ajay", Address: "Banglore" },
{ Id: 3, Name: "Narsi", Address: "Banglore" },
{ Id: 3, Name: "Peter", Address: "Banglore" },
];
var FilterArray = [];
var matched;
for(var i=0;i<myArray.length; i++){
matched = false;
var myArrayId = myArray[i].Id;
for(var j=0; j<FilterArray.length; j++){
var FilterArrayId = FilterArray[j].Id;
if(myArrayId === FilterArrayId){
matched = true;
FilterArray[j].Name.push(myArray[i].Name);
// no need to loop further
break;
}
}
if(!matched){
var obj = {
'Id' : myArrayId,
'Name' : [myArray[i].Name],
}
FilterArray.push(obj);
}
}
console.log(FilterArray);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
try this
var mpArray =[
{ Id: 1, Name: 'Madhu', Address: 'Upal' },
{ Id: 1, Name: 'Chandu', Address: 'Upal' },
{ Id: 2, Name: 'Srinu', Address: 'Kphb' },
{ Id: 2, Name: 'Vijay', Address: 'kphb' },
{ Id: 3, Name: 'Ajay', Address: 'Banglore' },
{ Id: 3, Name: 'Narsi', Address: 'Banglore' },
{ Id: 3, Name: 'Peter', Address: 'Banglore' },
];
var filterObject = {};
mpArray.forEach(function (item) {
if (!filterObject[item.Id]) {
filterObject[item.Id] = [];
}
filterObject[item.Id].push(item.Name);
});
console.log(filterObject);
$scope.mpArray =[
{ Id: 1, Name: 'Madhu', Address: 'Upal' },
{ Id: 1, Name: 'Chandu', Address: 'Upal' },
{ Id: 2, Name: 'Srinu', Address: 'Kphb' },
{ Id: 2, Name: 'Vijay', Address: 'kphb' },
{ Id: 3, Name: 'Ajay', Address: 'Banglore' },
{ Id: 3, Name: 'Narsi', Address: 'Banglore' },
{ Id: 3, Name: 'Peter', Address: 'Banglore' },
];
var FilterArray = [];
var FilteredArrayIds=[];
$scope.mpArray.forEach(
function(detailObj) {
if(FilteredArrayIds.indexOf(detailObj.Id)==-1)
return FilteredArrayIds.push(detailObj.Id);
});
for(var i=0; i<FilteredArrayIds.length;i++)
{
var result = $scope.mpArray.filter(function( obj ) {
return obj.Id == FilteredArrayIds[i];
});
var rsltNames = result.map(function(obj){
return obj.Name;
})
var filteredObj ={
id:FilteredArrayIds[i]+',' +rsltNames.join()
}
FilterArray.push(filteredObj);
}
console.log(filteredObj)

Angular UI grid :Show only selected objects

I have a code snippet
$scope.users = [
{ name: "abc", age: 10, location: 'Nagpur' },
{ name: "bcd", age: 30, location: 'Chennai' },
{ name: "efr", age: 29, location: 'Chennai' },
{ name: "abc", age: 25, location: 'Bangalore' },
{ name: "abc", age: 27, location: 'Vizag' }
];
$scope.gridOptions.data = $scope.users;
In grid how to show only users which have name = "abc"?
You just have to filter out all values from your array whose name is "abc"
angular.forEach($scope.users,function(val){
if(val.name=='abc')
$scope.abcUsers.push(val);
});
$scope.gridOptions.data = $scope.abcUsers;

Angular show list in alphabetical order and also show divider

**please anyone can help me i want to print list in Angularjs like this **
enter image description here
Use Order by
$scope.friends = [
{name: 'John', phone: '555-1212', age: 10},
{name: 'Mary', phone: '555-9876', age: 19},
{name: 'Mike', phone: '555-4321', age: 21},
{name: 'Adam', phone: '555-5678', age: 35},
{name: 'Julie', phone: '555-8765', age: 29}
];
<tr ng-repeat="friend in friends | orderBy:'name'">

You have to filter each group by the letters you want. Here's a Plunker Using this list:
$scope.myList = [{
id: 11,
name: 'Okra'
}, {
id: 12,
name: 'Musa'
}, {
id: 4,
name: 'Sky'
}, {
id: 13,
name: 'India'
}, {
id: 14,
name: 'Rose'
}, {
id: 15,
name: 'Titanic'
}, {
id: 16,
name: 'Onion'
}, {
id: 6,
name: 'Germany'
}, {
id: 17,
name: 'Beer'
}, {
id: 18,
name: 'Run'
}, {
id: 2,
name: 'Garden'
}, {
id: 19,
name: 'Mountain'
}]
One function to get the alphabets between the two:
function genCharArray(charA, charZ) {
var a = [], i = charA.charCodeAt(0), j = charZ.charCodeAt(0);
for (; i <= j; ++i) {
a.push(String.fromCharCode(i));
}
return a;
};
Then your filter:
app.filter("cfilter", function () {
return function (input, x, y) {
var groups = [];
var letters = genCharArray(x, y);
for (var i = 0; i < input.length; i++) {
for (var x = 0; x < letters.length; x++) {
if (input[i].name.substring(0, 1) == letters[x])
groups.push(input[i]);
}
} return groups;
}
});
And your HTML:
<div ng-repeat="w in myList | cfilter: 'A':'H' | orderBy: 'name'">
<div>{{w.name}}</div>
</div>
create one directive pass an array of letter and range of alphabates you want to disaply.
<dummy-directive data="arrayData" range="A-G"></dummy-directive>
<dummy-directive data="arrayData" range="H-L></dummy-directive>
<dummy-directive data="arrayData" range="M-P"></dummy-directive>
<dummy-directive data="arrayData" range="Q-Z"></dummy-directive>
Now question is that how to implement directive?
we will display sorted data.
