I'm using ng-repeat to iterate through a JSON object based on its keys. I've successfully limited the number of iterations to 5 by using ng-repeat="item in array|limitTo:5" for an array object.
However, when I attempt to limit the key repetitions with ng-repeat="key in json|limitTo: 5", it doesn't work. What steps should I take to solve this issue?
Develop a custom filter for managing a JSON object:
app.filter('customLimit', function () {
return function (jsonList, limitValue) {
var jsonLength = Object.keys(jsonList).length;
if (jsonLength <= limitValue)
return jsonList;
else
{
var trimmedJson = {};
//implement your trimming logic here to restrict the length
return trimmedJson;
}
};
});
Upon reviewing the documentation, it is evident that:
https://docs.angularjs.org/api/ng/filter/limitTo
The input being limited can be a source array, string, or number.
If needed, a custom filter can be created to enforce this limit.
To explore further, refer to: AngularJS limitTo filter for ngRepeat on an object (used like a dictionary)
In addition, why opt for using the limitTo filter on an object when the order cannot be managed? In such cases, utilizing an array would prove more effective.
