I'm encountering a 'syntax error: unexpected identifier' and my browser seems to be getting stuck in a loop after executing this code. I figured incorporating setInterval for delaying API requests was a sound strategy according to the API request guidelines.
var tempArray = [];
var arr = [];
//angular controller
for (var i = 0; i < 10; i++) {
setInterval($http.get(url).success(function(data) {
tempArray.push(data);
arr.push(tempArray);
}), 1000);
}
After @vlaz's explanation, it is clear that using setTimeout is preferable when you need to delay an action, while setInterval continuously calls the specified callback function.
I find it puzzling that the API guidelines suggest delaying requests... are they actually referring to "debouncing" instead?
In any case, encountering the "unexpected identifier" syntax error implies that a non-function argument was provided as the first parameter in setInterval. The correct approach is:
setTimeout(function() {
$http.get(url).success(function(data) {
tempArray.push(data);
arr.push(tempArray);
});
}, 1000);
The reason for this is that $http.get(url).success() does not return a callable function that can be passed directly to setTimeout.
Make sure that the $http is included in your Controller like this:
myApp.controller('MainController', function MainController($scope,$http) {...}
The use of setInterval allows the code to run repeatedly. In this scenario, it will loop every second.
