I'm trying to update values inside $scope.match.teams[0] with vaules for the players' names, but when I input in a single field, it is bound to every players' name for that team.
Controller:
$scope.match = {
teams: [
{
id: 0,
name: "",
players: [
{ id: 1, name: "" },
{ id: 2, name: "" },
{ id: 3, name: "" },
{ id: 4, name: "" },
{ id: 5, name: "" },
{ id: 6, name: "" },
{ id: 7, name: "" },
{ id: 8, name: "" },
{ id: 9, name: "" },
{ id: 10, name: "" },
{ id: 11, name: "" },
]
},
{
id: 1,
name: "",
players: [
{ id: 1, name: "" },
{ id: 2, name: "" },
{ id: 3, name: "" },
{ id: 4, name: "" },
{ id: 5, name: "" },
{ id: 6, name: "" },
{ id: 7, name: "" },
{ id: 8, name: "" },
{ id: 9, name: "" },
{ id: 10, name: "" },
{ id: 11, name: "" },
]
}
]
};
$scope.battingFirstSelected = function(){
switch ($scope.battingFirst.id) {
case 0:
$scope.battingSecond = $scope.match.teams[1];
case 1:
$scope.battingSecond = $scope.match.teams[0];
}
};
HTML:
Team batting first:
<select
ng-change="battingFirstSelected()"
ng-model="battingFirst"
ng-options="team.name for team in match.teams">
</select>
<div ng-repeat="player in battingFirst.players">
<input
class="form-control"
ng-model="match.teams[battingFirst.id].player.name"
value="" />
</div>
<div ng-repeat="player in match.teams[battingFirst.id].players">
{{ match.teams[battingFirst.id].player.name }}
</div>
The selection of the team works fine, it's just assigning the names that's the problem here.
The output of {{ match.teams[battingFirst.id] }} shows that I'm creating a new team every time I fill in one of the inputs, with a { player: {"name":"sdf"} } object attached to it.
You just need to try:
ng-model="player.name"
Your battingFirst is already a selected team from the above select. When you bind to players in this battingFirst, you bind correctly to players of the selected team.
<div ng-repeat="player in battingFirst.players">
<input
class="form-control"
ng-model="player.name"
value="" />
</div>
The problem you have is because ng-repeat creates child scopes. Therefore match.teams inside your ng-repeat is not the same as the match.teams of your parent scope.

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

The arrays I have
const users = [
{ id: 1, name: "field 1" },
{ id: 2, name: "field 2" },
{ id: 3, name: "field 3" },
{ id: 4, name: "field 4" },
];
const onlineUsers = [
{ id: 1, name: "field 1" },
{ id: 3, name: "field 3" }
];
I would like to find the online and offline ones by comparing the two series
I want to do:
const userLists = [
{ id: 1, name: "field 1", online: true },
{ id: 2, name: "field 2", online: false },
{ id: 3, name: "field 3", online: true },
{ id: 4, name: "field 4", online: false },
];
Using Array.map and Array.some
const users = [
{ id: 1, name: "field 1" },
{ id: 2, name: "field 2" },
{ id: 3, name: "field 3" },
{ id: 4, name: "field 4" },
];
const onlineUsers = [
{ id: 1, name: "field 1" },
{ id: 3, name: "field 3" }
];
var retVal=users.map(u=>{
var isOnline=onlineUsers.some(ou=> ou.id==u.id);//this will check if onlineUsers have some record with given userid
return {...u,online:isOnline}
})
console.log(retVal)
You can just traverse through the user list and you can find out the onlineuser using find and just push it in the onlineuserList.
const users = [
{ id: 1, name: "field 1" },
{ id: 2, name: "field 2" },
{ id: 3, name: "field 3" },
{ id: 4, name: "field 4" },
];
const onlineUsers = [
{ id: 1, name: "field 1" },
{ id: 3, name: "field 3" }
];
const userLists = [];
users.forEach(user => {
if(onlineUsers.find(q => q.id == user.id)){
userLists.push({
id: user.id,
name: user.name,
online: "true"
})
}
else{
userLists.push({
id: user.id,
name: user.name,
online: "false"
})
}
})
console.log(userLists);
a bit faster approach using Array.indexOf() and JSON.strigify()
const onlineUsers = JSON.stringify([
{ id: 1, name: "field 1" },
{ id: 3, name: "field 3" }
]);
const userList = users.map(user =>
({
...user,
online: onlineUsers.indexOf(JSON.stringify(user)) > -1
})
);
OR if you neither want to change original onlineUsers array nor declare another variable:
const userList = users.map(user =>
({ ...user, online: JSON.stringify(onlineUsers).indexOf(JSON.stringify(user)) > -1 })
);
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);
});

I'm trying to give an array to my makeSlider function.
The HTML5 Data attribute selects the correct array. Unfortunately, it is not interpreted as an array.
It does not work:
values = $(this).data("slider");
makeSlider(sliderID, targetID, values);
Is working:
makeSlider(sliderID, targetID, dataMehrfachauswahlmatrixLeft);
HTML:
<div class="noui-slider" id="slider-1" data-slider="dataMehrfachauswahlmatrixLeft">
<!-- slider here -->
</div>
<div class="hidden-md-up">
<!-- Store selected value -->
<input class="form-control slider-value" id="input-target-1">
</div>
JS (script.js):
$(document).ready(function() {
// slider array
// Matrix 1
var dataMehrfachauswahlmatrixLeft = [{
id: 1,
value: "sehr wichtig"
}, {
id: 2,
value: ""
}, {
id: 3,
value: ""
}, {
id: 4,
value: ""
}, {
id: 5,
value: "unwichtig"
}, {
id: null,
value: "weiß nicht"
}];
// Matrix 2
var dataMehrfachauswahlmatrixRight = [{
id: 1,
value: "in hohem Maße"
}, {
id: 2,
value: ""
}, {
id: 3,
value: ""
}, {
id: 4,
value: ""
}, {
id: 5,
value: "in geringem Maße"
}, {
id: null,
value: "weiß nicht"
}];
// build slider
var makeSlider = function(sliderID, targetID, values) {
...
}
// init slider
$(".noui-slider").each(function(index) {
var sliderID = $(this).attr("id"),
targetID = $(this).next().find(".slider-value").attr("id");
values = $(this).data("slider");
makeSlider(sliderID, targetID, values);
});
});
Problem with current implementation it that the variable value doesn't refers to the defined array. Its a string literal having value i.e. dataMehrfachauswahlmatrixLeft, dataMehrfachauswahlmatrixRight
Define the array in window or any other object scope.
// Matrix 1
window.dataMehrfachauswahlmatrixLeft = [...];
// Matrix 2
window.dataMehrfachauswahlmatrixRight = [...]
Then use Bracket notation to access object dynamic properties.
values = $(this).data("slider");
makeSlider(sliderID, targetID, window[values]);
An example here
$(document).ready(function() {
var myOBj = {};
// slider array
// Matrix 1
myOBj.dataMehrfachauswahlmatrixLeft = [{
id: 1,
value: "sehr wichtig"
}, {
id: 2,
value: ""
}, {
id: 3,
value: ""
}, {
id: 4,
value: ""
}, {
id: 5,
value: "unwichtig"
}, {
id: null,
value: "weiß nicht"
}];
// Matrix 2
myOBj.dataMehrfachauswahlmatrixRight = [{
id: 1,
value: "in hohem Maße"
}, {
id: 2,
value: ""
}, {
id: 3,
value: ""
}, {
id: 4,
value: ""
}, {
id: 5,
value: "in geringem Maße"
}, {
id: null,
value: "weiß nicht"
}];
// build slider
var makeSlider = function(sliderID, targetID, values) {
console.log(values)
}
$(".noui-slider").on('click', function() {
var values = $(this).data("slider");
makeSlider(1, 2, myOBj[values]);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class='noui-slider' data-slider='dataMehrfachauswahlmatrixLeft'>1</div>
<div class='noui-slider' data-slider='dataMehrfachauswahlmatrixRight'>2</div>
The JSON :
$scope.results=[
{
id: 1,
name: null,
class: "First"
},
{
id: 2,
name: John,
class: "First"
},
{
id: 3,
name: Mary,
class: "Second"
},
{
id: 4,
name: null,
class: "Third"
}
]
HTML:
<div class="col-md-6 form-group" data-ng-repeat="item in results| filter:{name:'!null'}">{{item.name}}</div>
I wanted to filter out the data that has name with value null.What's wrong with my code?
your json formate is not proper try this
plunker link http://plnkr.co/edit/H94f6XhyyhbvJ3F25NoA?p=preview
$scope.results=[
{
id: 1,
name: null,
class: "First"
},
{
id: 2,
name: "John",
class: "First"
},
{
id: 3,
name: "Mary",
class: "Second"
},
{
id: 4,
name: null,
class: "Third"
}
];
Solved it by adding this piece of code:
<div class="col-md-6 form-group" data-ng-repeat="item in results| filter:{name:'!!'}">{{item.name}}</div>
