I have changed my JSON, then I can't able to filter the data.
var result = $filter('filter')(foo.results, {id:2426})[0];
if you limit on your JSON data
and you can make sure the data property value is num
maybe you can try this ...
var foo = {
"count": 70,
"language": "en",
"0": {
"id": "2420",
"name": "Medical Center"
},
"1": {
"id": "7840",
"name": "Conference Room"
},
"2": {
"id": "2426",
"name": "Deck 5 Starboard"
}
};
foo.results = [];
for(var property in foo){
if(property == parseInt(property, 10).toString()){
foo.results.push(foo[property]);
}
}
var result = $filter('filter')(foo.results, {id:2426})[0];
$scope.name = result.name;
wish help !!

I need your opinion in this situation:
I get from API with this function:
getRS(
idProject: string
): Observable<ResponseModel<RSModel>> {
return this.http.get<ResponseModel<RSModel>>(
ApiUrlsConfig.getRS(
idProject
)
);
}
this response:
{
"data": [
{
"id": "id1",
"state": 1,
"note": null
},
{
"id": "id1",
"state": 2,
"note": "Reason 1"
},
{
"id": "id2",
"state": 2,
"note": "Reason updated3",
}
],
"result": null
}
I need to use filter in this response because I should be get the last state for each id. For example, I want to display state 2 in item with id: id1. For this I want to use filter. The problem is because I can't use filter on it, I don't understand why.
I tried to write this code:
#Input() set jobId(jobId: string) {
this.optionsService
.getRS(
this.idProject
)
.pipe()
.subscribe((res) => {
let resId = res.filter((aaa)=>{
if(aaa.id === jobId){
res.slice(-1)[0].id
}
}
)
});
}
Not function.
Please can you share with me any idea?
Thank you
Try this logic:
Loop backwards throw it.
Loop backwards over index to the start.
Splice duplicates.
let response = {
"data": [
{
"id": "id1",
"state": 1,
"note": null
},
{
"id": "id1",
"state": 2,
"note": "Reason 1"
},
{
"id": "id2",
"state": 2,
"note": "Reason updated3"
}
],
"result": null
}
let data = response.data;
for (let i = data.length - 1; i >= 0; i--) {
for (let j = i - 1; j >= 0; j--) {
if (data[i].id === data[j].id) {
data.splice(j, 1);
j++;
}
}
};
console.log(data);
try this:
if(aaa.id == jobId){
return res.slice(-1)[0].id
}
I have an array list which needs to be converted to a single object with few of the values from array list using TypeScript in Angular 8. Below is the array:
"arrayList": [{
"name": "Testname1",
"value": "abc"
},
{
"name": "Testname2",
"value": "xyz"
}
]
This needs to be converted to the below format,
data: {
"Testname1": "abc",
"Testname2": "xyz",
}
No matter how much i try, i end up creating a list instead of a single object. Can you please help on the same?
You can use as follows,
var arr = [
{
"name": "Testname1",
"value": "abc"
},
{
"name": "Testname2",
"value": "xyz"
}
];
var result = {};
for (var i = 0; i < arr.length; i++) {
result[arr[i].name] = arr[i].value;
}
console.log(result);
Try with using .reduce() as the following:
const arrayList = [{ "name": "Testname1", "value": "abc" }, { "name": "Testname2", "value": "xyz" }];
const data = arrayList.reduce((a, {name, value}) => {
a[name] = value;
return a;
}, {});
const result = { data };
console.log(result);
Use Array.map() to get a list of [name, value] entries, then use Object.fromEntries() to convert to an object:
const arrayList = [{ "name": "Testname1", "value": "abc" }, { "name": "Testname2", "value": "xyz" }];
const result = Object.fromEntries(arrayList.map(({ name, value }) => [name, value]));
console.log(result);
Please use the below code
const rawData = {
"arrayList": [{
"name": "Testname1",
"value": "abc"
},
{
"name": "Testname2",
"value": "xyz"
}
]
};
const updatedData = {
data: {}
};
for (const item of rawData["arrayList"]) {
updatedData.data[item.name] = item.value;
}
console.log(updatedData);
Hi I am implementing a chart in my Angularjs Application, You can see this plunker http://jsfiddle.net/fusioncharts/73xgmacm/ The thing which I want to achieve is to change the value attribute to profit. How can I do this ? I want to display profit not values.
Regards
After 2 days I finally find out the answer. The thing is You cannot change the Fusionchart attribute value but you can change the attribute of your API once you fetched. I used a loop after I fetched the API and replace the 'profit' attribute with value in this way I made the chart. Yes The thing which i had been ignoring was the use of 'variable' instead of scope. If you see this example you would understand Example Here. I am sharing my code May be it helps someone else too.
Give below is my json array which i called tps.json
[
{
"index": "1",
"variantoption": "fan-green",
"company": "sk fans",
"quantity": "650",
"profit": "78296",
"loss": "8457",
"year": "2016"
},
{
"index": "2",
"variantoption": "fan-white",
"company": "al ahmed fans",
"quantity": "450",
"profit": "78296",
"loss": "8457",
"year": "2016"
},
{
"index": "3",
"variantoption": "fan-purple",
"company": "asia fans",
"quantity": "350",
"profit": "78296",
"loss": "8457",
"year": "2016"
},
{
"index": "4",
"variantoption": "fan-yellow",
"company": "falcon fans",
"quantity": "250",
"profit": "78296",
"loss": "8457",
"year": "2016"
}
]
and here is my controller
$http.get('js/tps.json').success(function (data) {
var chartdata = data;
var arrLength = chartdata.length;
console.log(arrLength);
for (var i = 0; i < arrLength; i++) {
if (chartdata[i]['profit'] && chartdata[i]['index']) {
chartdata[i].value = chartdata[i].profit;
delete chartdata[i].profit;
chartdata[i].label = chartdata[i].index;
delete chartdata[i].index;
console.log(chartdata);
}
}
console.log(chartdata);
FusionCharts.ready(function () {
var tps = new FusionCharts({
type: 'column2d',
renderAt: 'chart-container',

Hi can somebody help Removing element from nested json array like this
JSON
[{
"id": 1,
"name": "Furniture & Fixture",
"choice": {
"0": {
"req_goods": "table",
"qty": "10"
},
"1": {
"req_goods": "chair",
"qty": "5"
}
}
}, {
"id": 2,
"name": "Miscellaneous Property",
"choice": {
"0": {
"req_goods": "Office Rent",
"qty": "1"
}
}
}]
here how do I remove choice 1 of id 1 .
HTML
<div ng-repeat="cb in capital_budgets">
<div ng-repeat="choice in choices[$index]">
<input ng-model="cb.choice[$index].req_goods">
<input ng-model="cb.choice[$index].qty">
<button ng-hide="$first" ng-click="removeChoice($parent.$index,$index)">-</button>
</div>
<button ng-click="addNewChoice($index)">+</button>
</div>
JS
$scope.capital_budgets = [{"id":1,"name":"Furniture & Fixture"},
{"id":2,"name":"Miscellaneous Property"}];
$scope.choices = [{}];
$scope.choices[0] = [{}];
$scope.choices[1] = [{}];
$scope.choices[2] = [{}];
$scope.choices[3] = [{}];
$scope.choices[4] = [{}];
$scope.addNewChoice = function(id) {
$scope.choices[id].push({});
};
$scope.removeChoice = function(parent_id, id) {
$scope.choices[parent_id].splice(id, 1);
};
The Above removeChoice() remove last element but I want to remove the element that user choose to remove. please help i have been trying from 2 days.
You can make 'choice' of the array type as follows and use the index of the particular choice in the ng-repeat directive to remove the choice from the choices array.
angular
.module('demo', [])
.controller('DefaultController', DefaultController);
function DefaultController() {
var vm = this;
vm.items = [
{
"id": 1,
"name": "Furniture & Fixture",
"choices": [
{
"id": 1,
"req_goods": "table",
"qty": "10"
},
{
"id": 2,
"req_goods": "chair",
"qty": "5"
}]
}, {
"id": 2,
"name": "Miscellaneous Property",
"choices": [
{
"id": 1,
"req_goods": "Office Rent",
"qty": "1"
}]
}];
vm.removeChoice = removeChoice;
vm.addChoice = addChoice;
function removeChoice(itemId, index) {
for (var i = 0; i < vm.items.length; i++) {
if (vm.items[i].id === itemId) {
vm.items[i].choices.splice(index, 1);
break;
}
}
}
function addChoice(index) {
var id = vm.items[index].choices.length + 1;
vm.items[index].choices.push({
id: id,
req_goods: "",
qty: 0
});
}
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="demo">
<div ng-controller="DefaultController as ctrl">
<div ng-repeat="item in ctrl.items">
<h3>{{item.name}}</h3>
<div ng-repeat="choice in item.choices">
<input type="text" ng-model="choice.req_goods" />
<input type="text" ng-model="choice.qty" />
<button type="button" ng-click="ctrl.removeChoice(item.id, $index)">Remove</button>
</div>
<button type="button" ng-click="ctrl.addChoice($index)">Add</button>
</div>
</div>
</div>
You can remove choice "1" of id 1 using the below code snippet.
var json = [
{
"id": 1,
"name": "Furniture & Fixture",
"choice": {
"0": {
"req_goods": "table",
"qty": "10"
},
"1": {
"req_goods": "chair",
"qty": "5"
}
}
}, {
"id": 2,
"name": "Miscellaneous Property",
"choice": {
"0": {
"req_goods": "Office Rent",
"qty": "1"
}
}
}];
function removeChoice(json, parentId, choice) {
for (var i = 0; i < json.length; i++) {
if (json[i].id === parentId) {
delete json[i].choice[choice];
break;
}
}
}
removeChoice(json, 1, "1");
console.log(json);
If you want the the choice also to be of the same type as its parent element i.e. an array you could change your JSON as follows and do as shown in the below code snippet to remove a choice from the JSON
var json = [
{
"id": 1,
"name": "Furniture & Fixture",
"choices": [
{
"id": 1,
"req_goods": "table",
"qty": "10"
},
{
"id": 2,
"req_goods": "chair",
"qty": "5"
}]
}, {
"id": 2,
"name": "Miscellaneous Property",
"choices": [
{
"id": 1,
"req_goods": "Office Rent",
"qty": "1"
}]
}];
function removeChoice(json, parentId, choiceId) {
for (var i = 0; i < json.length; i++) {
if (json[i].id === parentId) {
for (var j = 0; j < json[i].choices.length; j++) {
if (json[i].choices[j].id === choiceId) {
json[i].choices.splice(j, 1);
break;
}
}
break;
}
}
}
removeChoice(json, 1, 1);
console.log(json);
In both of the above methods I've passed the source you want to modify as a parameter to the removeChoice function whereas you can also directly use a variable available within the scope of execution of the removeChoice function and pass only parentId and choiceId as parameters in the below code snippet, you can replace items with the object on your controller's $scope.If you prefer isolation of the code you can pass the items object as a parameter to the removeChoice function as it won't be dependent on the external components directly being used in the method body, I would suggest to have separation of concerns.
var items = [
{
"id": 1,
"name": "Furniture & Fixture",
"choices": [
{
"id": 1,
"req_goods": "table",
"qty": "10"
},
{
"id": 2,
"req_goods": "chair",
"qty": "5"
}]
}, {
"id": 2,
"name": "Miscellaneous Property",
"choices": [
{
"id": 1,
"req_goods": "Office Rent",
"qty": "1"
}]
}];
function removeChoice(parentId, choiceId) {
for (var i = 0; i < items.length; i++) {
if (items[i].id === parentId) {
for (var j = 0; j < items[i].choices.length; j++) {
if (items[i].choices[j].id === choiceId) {
items[i].choices.splice(j, 1);
break;
}
}
break;
}
}
}
removeChoice(1, 1);
console.log(items);
Try This
$scope.removeChoice = function(parent_id,id) {
var TempArr=[];
var parentLength=$scope.choices[parent_id].length;
for(i=0;i<parentLength;i++ ){
if(parentLength[i]!==id){
TempArr.push(parentLength[i]);
}
if(i==parentLength-1){
$scope.choices[parent_id]=[];
$scope.choices[parent_id]=TempArr;
}
}
};
How I can create a $filter with custom function to determining if match ?
This is a json sample with structure:
$scope.routes =[
{
"id": 0,
"name": "Rosa Barnes",
"origin": [
{
"address": [
{
"locality": "Madrid",
"country": "ES"
}
]
}
]
},
{
"id": 1,
"name": "Wright Montoya",
"origin": [
{
"address": [
{
"locality": "London",
"country": "UK"
}
]
}
]
},
{
"id": 2,
"name": "Pearson Johns",
"origin": [
{
"address": [
{
"locality": "London",
"country": "UK"
}
]
}
]
}
];
I want a $filter that passing one country, match in origin.address.country , is possible?
I proved this code but not works:
$scope.routesToShow = $filter('filter')($scope.routes, {origin.address.country: "UK"});
Here there are a demo:
http://jsfiddle.net/86U29/43/
Thanks
What you need is a custom filter. It also looks like you might need to tweak your data structure too.
Take a look at this:
app.filter('CustomFilter', function () {
function parseString(propertyString) {
return propertyString.split(".");
}
function getValue(element, propertyArray) {
var value = element;
propertyArray.forEach(function (property) {
value = value[property];
});
return value;
}
return function (input, propertyString, target) {
var properties = parseString(propertyString);
return input.filter(function (item) {
return getValue(item, properties) == target;
});
}
});
You could use this filter, like this:
$scope.routesToShow = $filter('CustomFilter')($scope.routes, 'origin.address.country', 'UK');
Here is an updated jsfiddle (notice the updated data structure): http://jsfiddle.net/moderndegree/86U29/44/
You can find more information on creating custom filters here:
https://docs.angularjs.org/guide/filter#creating-custom-filters
Simply.
var filter = function(obj){
return obj.origin[0].address[0].country === 'UK';
}
$scope.routesToShow = $filter('filter')($scope.routes, filter);
