I'm sure I'm missing something obvious but the below code does not work when the currentRecord found is true.
What is the best way to iterate through an array and when a match is found, return that record? I think forEach here is part AngularJS.
function getCurrentRecord() {
homePageVideos.forEach(function(rec) {
if (rec.currentRecord === true){
return rec;
}
});
}
From MDN documentation of Array.prototype.forEach:
Note: There is no way to stop or break a
forEach()loop. The solution is to useArray.prototype.every()orArray.prototype.some(). See example below.
Same goes for angular.forEach.
But if you were to use a simple for-loop, you could do it like so:
for (var i=0; i < homePageVideos.length; i++){
var rec = homePageVideos[i];
if (rec.currentRecord === true){
return rec;
}
}
You could simply use angular filter. Inside controller you could accomplish this by using $filter inside controller
function getCurrentRecord() {
var result = $filter('filter')(homePageVideos, true, true); //strict checking
return result.length > 0? result[0]: [];
}
JavaScript provides several array iteration functions. I would use filter() but the solution would depend on the browser compatibility you require (IE9+, FF1.5+).
function getCurrentRecord() {
return homePageVideos.filter(function(rec) {
return rec.currentRecord
});
}
