I've been working on a function within my service that retrieves data
function getSomeData() {
return $http
.get('/someData.json')
.then(itWorked)
.catch(onFail);
Currently, this function returns all the records from the JSON file. However, I'm facing a challenge when trying to retrieve just a single record based on its ID. It should be a straightforward search, but so far I haven't had any luck.
When dealing with an array, creating your own find function is a viable option:
let foundElement;
data.forEach(function(element){
if(element === targetId){
foundElement = element;
}
});
Alternatively, for a more efficient solution, consider using Lodash (which comes highly recommended), enabling you to achieve the same result in just one line of code:
let foundElement = _.find(data, {id: targetId});
To retrieve a specific record from a list, you can utilize the $filter service.
var filterOutRecordFromList = function(
arrayObjects, condition) {
var filteredData = $filter('filter')(arrayObjects,condition,true);
return filteredData[0];
};
For example, if you want to find a record with a specific ID in a JSON list, you can use the filterOutRecordFromList function like this:
var selectedRecord = filterOutRecordFromList(data,{id:specificId},true);
Below is a JSON object example: [ {'car':'punto','brand':'fiat','color':'black','model':'2007'}, {'car':'XUV500','brand':&ap ...
