Sample text

Examples of such events include XHR or server calls, page loads, and user interactions like click or type. In our previous example with the ng-repeat, we have a template that shows the note’s label and status. That template accesses a variable called note, which is created in our for each loop that is the ng-repeat. Now, if each template accessed the same context, each instance would show the same text. But to ensure that each template instance of the ng-repeat shows its own value, each ng-repeat also gets its own scope with a variable called note defined in it, which is specific to it.

The next point of interest is the template that we used for the ng-repeat. Inside the context of the ng-repeat, we now have a new variable, note, which is not present in our controller. This is created by ng-repeat, and each instance of the ng-repeat has its own version and value of note, obtained from each item of the array. The final thing to note is that we used the double-curly notation to print the note’s label, but used a directive called ng-bind for the note’s done field. There is no functional difference between the two; both take the value from the controller and display it in the UI.

No need for the double-curly syntax. Working with ng-repeat The ng-repeat directive is one of the most versatile directives in AngularJS, and can be used for a whole variety of situations and requirements. We saw how we can use it to repeat an array in the previous examples. In this section, we will explore some of the other options we have when using the ng-repeat directive. notes = { shyam: { id: 1, label: 'First Note', done: false }, Misko: { id: 3, label: 'Finished Third Note', done: true }, brad: { id: 2, label: 'Second Note', done: false } }; }]); In this example, we have intentionally capitalized Misko while leaving brad and shyam lowercase.
