How to check uniquness while pushing values into array using Angular JS? - angularjs

$scope.displayyears = [];
$scope.Joinyear = function(display) {
$scope.yeardisplay = display;
$scope.yeardisp = $scope.displayyears.push($scope.yeardisplay);
$scope.displayyearss = uniq($scope.yeardisp)
}
it throws error like "uniq is undefined"..How we check uniqueness??

Try checking if the yeardisplay is already in the array before you add it
$scope.displayyears = [];
$scope.Joinyear=function(display){
$scope.yeardisplay=display;
if ($scope.displayyears.indexOf(display) == -1) {
$scope.displayyears.push(display);
}
}

Flutter : How to get the value of the other properties from a List?

All of my Json data is already inside in my model. And I have also a list of data inside "selectedBranches[]". What do I want is to get the other value of the other properties which is the BranchCode and BranchId based on the value from the selectedBranches list and put it to the another list.
My selectedBranches List is consist of list of branchFullName properties from my json data.
But dart says The argument type 'List' can't be assigned to the parameter type 'Pattern'.
#Code Snippet#
selectedBranches = [ex1,ex2,ex3,ex4];
selectedAssignBranches = [];
assignBranch() {
branchModel1 = GetBranchList.fromJson(jsonData1);
var newArr = branchModel1.data;
for (var u in newArr) {
AssignBranch assignModel = new AssignBranch();
if (u.branchFullName.contains(selectedBranches/*error*/)) {
assignModel.BranchCode = u.branchCode;
assignModel.BranchID = u.brID;
selectedAssignBranches.add(assignModel);
}
}
}
#Model#
class Datum {
String branchCode;
String branchName;
String stat;
String brID;
String branchFullName;
I already solve the problem. You just need to have a nested for loop. Thats it!
assignBranch() {
branchModel1 = GetBranchList.fromJson(jsonData1);
var newArr = branchModel1.data;
for (var i in selectedBranches) {
for (var u in newArr) {
if (u.branchFullName == (i)) {
AssignBranch assignModel = new AssignBranch();
assignModel.BranchCode = u.branchCode;
assignModel.BranchID = u.brID;
selectedAssignBranches.add(assignModel);
}
}
}
}

how to check a value in array object angularjs

i have this array object:
$scope.datas.labels=['10','20','30']
and also i have a function return an array object like this:
response.labels=['10','20','30','50','100','80']
i created a function which recieve the last result..but what i want is to check if a value in response.labels exists in the $scope.datas.labels i dont want to insert it..to avoid duplicated data in $scope.datas.labels, how i can do that??
i tried this but i didnt work:
$scope.concatToData=function (response) {
if($scope.datas.labels=='') {
$scope.datas.labels = $scope.datas.labels.concat(response.labels);
}else {
var i;
for (i = 0; i < $scope.datas.labels.length; i++) {
alert('qa' + JSON.stringify($scope.datas.labels));
alert('res' + JSON.stringify(response.labels));
if ($scope.datas.labels[i] !== response.labels[i]) {
$scope.datas.labels = $scope.datas.labels.concat(response.labels[i]);
} else {
break;
}
}
}
$scope.datas.datasets = $scope.datas.datasets.concat(response.datasets);
}
Try this it will work as per your expectation and requirement.
var arr1=['10','20','30'];
var arr2=['10','20','30','50','100','80'];
for (var i in arr2) {
if(arr2[i] != arr1[i]) {
arr1.push(arr2[i]);
}
}
document.getElementById('result').innerHTML = arr1;
#result {
font-weight:bold;
}
<div id="result"></div>
Take a look at the lodash library, you'll find it useful, and this will be useful for you too:
let common = _.intersection($scope.datas.labels, response.labels);
if (_.size(common) && _.includes(common, 'myValue')) {
// You have a winner;
// This item (myValue) is in both;
} else {
}
Hope that helps.
You can also try that:
var response = ['foo', 'fabio'];
var labels = ['foo'];
var result = response.filter((value) => {
return labels.filter((rs) => {
return rs == value;
}).length == 0;
});
It will return only the data that does not exists on $scope.datas.labels.

checkbox filter for json array in Angularjs

I have create a filter but this filter is not working with array inside array.
'http://plnkr.co/edit/oygy79j3xyoGJmiPHm4g?p=info'
Above plkr link is working demo.
app.filter('checkboxFilter', function($parse) {
var cache = { //create an cache in the closure
result: [],
checkboxData: {}
};
function prepareGroups(checkboxData) {
var groupedSelections = {};
Object.keys(checkboxData).forEach(function(prop) {
//console.log(prop);
if (!checkboxData[prop]) {
return;
} //no need to create a function
var ar = prop.split('=');
//console.log("ar is - "+ar);
if (ar[1] === 'true') {
ar[1] = true;
} //catch booleans
if (ar[1] === 'false') {
ar[1] = false;
} //catch booleans
/* replacing 0 with true for show all offers */
if(ar[0]=='SplOfferAvailable.text'){
ar[1]='true';
}else{
}
//make sure the selection is there!
groupedSelections[ar[0]] = groupedSelections[ar[0]] || [];
//at the value to the group.
groupedSelections[ar[0]].push(ar[1]);
});
return groupedSelections;
}
function prepareChecks(checkboxData) {
var groupedSelections = prepareGroups(checkboxData);
var checks = [];
//console.log(groupedSelections);
Object.keys(groupedSelections).forEach(function(group) {
//console.log("groupedSelections- "+groupedSelections);
//console.log("group- "+group);
var needToInclude = function(item) {
//console.log("item- "+item);
// use the angular parser to get the data for the comparson out.
var itemValue = $parse(group)(item);
var valueArr = groupedSelections[group];
//console.log("valueArr- "+valueArr);
function checkValue(value) { //helper function
return value == itemValue;
}
//check if one of the values is included.
return valueArr.some(checkValue);
};
checks.push(needToInclude); //store the function for later use
});
return checks;
}
return function(input, checkboxData, purgeCache) {
if (!purgeCache) { //can I return a previous 'run'?
// is the request the same as before, and is there an result already?
if (angular.equals(checkboxData, cache.checkboxData) && cache.result.length) {
return cache.result; //Done!
}
}
cache.checkboxData = angular.copy(checkboxData);
var result = []; // this holds the results
//prepare the checking functions just once.
var checks = prepareChecks(checkboxData);
input.every(function(item) {
if (checks.every(function(check) {
return check(item);
})) {
result.push(item);
}
return result.length < 10000000; //max out at 100 results!
});
cache.result = result; //store in chache
return result;
};
});
above code is for check box filter.
when i click on checkbox called "Availability" it does not filter the result.
Please help me out.
Thanks.
I think that the way you are navigating through json is wrong because if you put in this way it works
"Location": "Riyadh",
"AvlStatus": "AVAILABLE"
"Rooms": {.....
You have to go in some way through Rooms and right now I think you're not doing that

angular's equivalent of ko.utils.arrayMap or adding extra properties to returned data array?

Im in the process of converting a knockout app to angular, I currently get an array of objects from the server but I would like to extend each object by adding some extra properties.
In knockout I would do the following:
var mappedResults = ko.utils.arrayMap(results, function(item) {
item.selected = ko.observable(true);
item.viewPreview = ko.observable(false);
return new reed.search.Candidate(item, self.viewModel.fileDownloadFailCookieName);
});
and the Candidate viewmodel:
reed.search.Candidate = function(data, fileDownloadFailCookieName) {
debugger
if (data == null) {
throw 'Error: cannot initiate candidate';
}
this.fileDownloadFailCookieName = fileDownloadFailCookieName;
this.candidateId = data.CandidateId;
this.name = data.Name;
this.surname = data.Surname;
this.forename = data.Forename;
this.displayLocation = data.DisplayLocation;
this.lastJobDetails = data.LastJobDetails;
this.displayPayRate = data.DisplayPayRate;
this.lastSignIn = data.LastSignIn;
this.downloadCVUrl = data.DownloadCVUrl;
this.additionalInfo = data.AdditionalInfo;
this.isAvailable = (data.IsAvailable) ? "Availability confirmed" : "";
this.availableMornings = data.AvailableMornings;
this.availableAfternoons = data.AvailableAfternoons;
this.availableEvenings = data.AvailableEvenings;
this.availableWeekends = data.AvailableWeekends;
this.availableShiftWork = data.AvailableShiftWork;
this.availableNights = data.AvailableNights;
this.availabilityUpdatedOn = data.AvailabilityUpdatedOn;
this.availabilityUpdatedOnDate = "| <strong>Availability updated</strong> " + data.AvailabilityUpdatedOn;
this.isAvailableForSomething =
this.availableMornings
|| this.availableAfternoons
|| this.availableEvenings
|| this.availableWeekends
|| this.availableShiftWork
|| this.availableNights;
this.viewPreview = ko.observable(false);
this.selected = ko.observable(false);
this.hasBeenNotified = ko.observable(false);
this.select = function() {
this.selected(true);
};
this.deSelect = function() {
this.selected(false);
};
this.HasFlagSet = function(availability) {
return availability ? "availabilitySelected" : "availabilityNotSelected";
};
this.ajaxCvDownload = function() {
var path = window.location.href,
iframeError,
cookieName = this.fileDownloadFailCookieName;
// download path
path = path.match(/(.+\/)/ig)[0];
if (path.match(/home/ig)) {
path = path.replace('home', this.downloadCVUrl);
} else {
path = this.downloadCVUrl;
};
$('<iframe />').attr('src', path)
.hide()
.appendTo('body').load(function() {
var message = decodeURIComponent(reed.shared.utils.getCookie(cookieName));
message = message.replace(/\+/g, " ");
if (message.length > 0 && message != "null") {
reed.shared.utils.showMessage(message, "Download Failed");
}
});
}
}
how can I achieve the same functionality in angular?
You don't need angular for this array itself contains a map function and all modern browsers support it.
var mappedResults = results.map(function(item) {
item.selected = true;
item.viewPreview = false;
return new reed.search.Candidate(item,
self.viewModel.fileDownloadFailCookieName);
});
Some other things you can improve. Firstly if you are using webapi to return data, use a formatter that fixes casing.Check this blog http://blogs.msmvps.com/theproblemsolver/2014/03/26/webapi-pascalcase-and-camelcase/
Once you have the formatter lines such as these are not required
this.surname = data.Surname;
You can then use angular.extend to copy properties into your class.

AS3/Flash: check if a variable value exists in an array II

Some days ago, Cherniv gave to me this tip:
var name = "Nora";
var names:Array = ["Mary", "Porter", "Nora", "Flint", "Elsa", "Clair",...];
if( names.indexOf( name ) > -1 )
{
// Success
}
Now, I can't check the existence of "Nora" in this array:
var names:Array = [{label:"Mary"}, {label:"Porter"},{label:"Nora"}, ...];
I'll appreciate any help.
Cheers.
UPDATE:
Now it's working. I did use:
for each (var obj:Object in list)
{
if (obj.label == compList.text)
{
updateList = 1;
break;//stops the loop;
}
}
if (updateList == 1)
{
removeCompany();
}
else
{
var nativeAlert:NativeAlert = new NativeAlert();
nativeAlert.alert("You can't update the name!");
}
Is this OK or is an ugly solution?
Thanks
for each( var obj : Object in names )
{
if( obj.label == "Nora" )
{
// Success;
break;//stops the loop;
}
}
I can make it more complex/flexible if you wish.
