I have successfully pulled EPOCH dates and converted them into strings, but my previous code did not check or remove duplicates. Does anyone have any suggestions on what I can add to accomplish this? The timestamp in this case is the EPOCH date that I retrieved from live data! ANGULARJS1
let dateDictionary = {};
for (index = 0; index < dataFromDatabase.length; index++) {
let temporaryDateString = "";
let temporaryDate = new Date(dataFromDatabase[index].TIMESTAMP);
temporaryDateString += temporaryDate.getFullYear();
temporaryDateString += "-";
if ((temporaryDate.getMonth()+1) < 10) {
temporaryDateString += "0";
}
temporaryDateString += (temporaryDate.getMonth()+1);
temporaryDateString += "-";
if (temporaryDate.getDate() < 10) {
temporaryDateString += "0";
}
temporaryDateString += temporaryDate.getDate();
// create a dictionary, and if entry for this string already exists, skip
if (!dateDictionary[temporaryDateString]) {
dateDictionary[temporaryDateString] = true;
}
}
If you want your dates in an array, simply use:
let uniqueDates = Object.keys(dateDictionary)
To prevent duplicates, you can utilize the set method:
const uniqueSet = new Set(["apple", "banana", "orange", "apple"]);
uniqueSet.has("apple") // true
uniqueSet.size === 3); // true
By passing an array to the Set constructor, you can initialize the set with specific items.
To eliminate duplicates, you can utilize the angular.equals method:
let uniqueArray = [];
angular.forEach($scope.items, function(item) {
let isDuplicate = false;
angular.forEach(uniqueArray, function(uniqueItem) {
if(angular.equals(item.id, uniqueItem.id)){ isDuplicate = true };
});
if(!isDuplicate && item.name !== "") { uniqueArray.push(item); }
});
$scope.items = uniqueArray;
