![]() The sorted array so the original array isn’t affected. Iterate or Loop through each Array item or Object using AngularJS forEach. The sort method makes a copy of the array, sorts it and then returns We can create our own pipe that sorts values in the order we want before we display them by using the array sort method. In addition to components, we can create pipes in Angular that let us manipulate data in templates to display them in the format we want. The orderBy after the colon is the orderBy instance variable in AppComponent which we set as the argument of the orderBy pipe.Īs a result, we should see the items displayed in the list initially sorted by their age values in ascending order. Then when we click Toggle Sort, we see the sort order reversed so the age values are sorted in descending order. To add a button that lets us toggle the value of orderBy between "asc" and "desc".Īnd then we render the items in persons after they’re sorted by the orderBy pipe we just created. We have an array of Person objects set as the value of the persons instance variable.Īlso, we have the orderBy instance variable initially set to "asc". In, we should see something like: import, ] This will create the files and register them in the Angular app module so we can make changes to the pipe file and use it right away. To start, we run: ng generate pipe lowerCase In this example, we will create a pipe that converts strings to lowercase before displaying them. Then you try to use ngFor but a wild error message appears: Cannot find a differ supporting object object Object of type object. To create the files for the pipe and register the pipe in our Angular app module, we use the ng g command that comes with Angular CLI. We can create our own pipes to transform data in our templates before displaying them. In this article, we’ll look at how to add an orderBy pipe into our app and use it in our template. In addition to components, we can create pipes that let us manipulate data in templates to display them in the format we want. Learn how to use the orderBy pipe to manipulate data in templates to display them in the format we want.Īngular is a component-based framework that lets us create interactive web frontends for users by composing components together.
