It seems like there might be a simple solution that I'm overlooking, but the code below isn't functioning as expected when the currentRecord is found to be true.
How can I efficiently loop through an array and return the record when a match is found? I believe that AngularJS could be helpful in this scenario.
function getCurrentRecord() {
homePageVideos.forEach(function(rec) {
if (rec.currentRecord === true){
return rec;
}
});
}
According to information found on the MDN documentation of Array.prototype.forEach:
It is important to note that there is no way to stop or break a forEach() loop. A possible solution is to utilize Array.prototype.every() or Array.prototype.some(). An example is provided below.
The same restriction applies to angular.forEach.
However, if you opt to use a basic for-loop, you can achieve the desired outcome like this:
for (var i=0; i < homePageVideos.length; i++){
var rec = homePageVideos[i];
if (rec.currentRecord === true){
return rec;
}
}
If you want to achieve this, you can make use of an angular filter. In your controller, you can simply implement this by making use of the $filter functionality.
function retrieveCurrentItem() {
var data = $filter('filter')(videoList, true, true); //enabling strict checking
return data.length > 0 ? data[0] : [];
}
When working with JavaScript arrays, there are a variety of array iteration functions available. One approach is to utilize the filter() function, although its suitability depends on the desired browser compatibility (IE9+, FF1.5+).
function findCurrentRecords() {
return homePageVideos.filter(function(video) {
return video.currentRecord;
});
}
