Dynamic order in AngularJS

Question

I have an array of objects that I want to order dynamically, based on the value from the dropdown menu. This is what I still have on my list:

ng-repeat="item in filteredItems = (items | filter:searchInput | orderBy:canBeAnything)" 

However, the problem is that sorting can be an attribute of an object or a computed value using a function. It should also be able to sort in descending order (optional).

I know that I can use the string for the canByAnything variable for orderBy, passing the attribute of an object, for example:

 "-creationDate" // descending ordering on creation date "customer.lastname" // ascending ordering on customers last name 

I also know that I can order the function:

 orderBy:myCalculatedValueFunction // will order in an ascending way based on a calculated value, for example calculating the total price of the object if it was an order or something 

But I do not know and want to achieve:

• How to combine it so that I can use functions for sorting in combination with attributes / properties of objects. I mean one or the other, dynamically, based on what the user selected. Which can be an attribute or a computed value, neither descending nor ascending.
• How to sort the calculated value in descending order.

Answer 1

Update orderBy:myCalculatedValueFunction approximately orderBy:dynamicOrderFunction :

 $scope.dynamicOrderFunction = function() { if (orderByString) { return '-creationDate'; } else { return myCalculatedValueFunction; } } 

orderBy also has a third property, which takes a boolean and overrides orderBy when true . ( orderBy:dynamicOrderFunction:reverseOrder where $scope.reverseOrder = true; // or false )

In fact, you will run into problems trying to switch orderBy between the line. Checkout this jsfiddle for dynamic ordering.

So, you need to create your own filter and do what you want in it, there are tons of google example. Just do a search:

angular custom filter

Abstracts of the last days, I have problems with creating filters, and I found that: https://github.com/a8m/angular-filter

I added it immediately to my dependencies, I know that I will use it in the near future. Maybe this will help too. Do not forget to confirm your answer if it helps you solve your problem;)
