Angular makes event handlers simple: you add a click attribute to the element. The value you assign to this attribute depends on the approach you want to take. You can provide an expression that Angular will evaluate. This means that when the element is clicked you want Angular to increase the value of the count property by one. You can also assign a method. This means that you want Angular to execute a method when the element is clicked.

You can also pass parameters to this method. Note the content property, which is a string and the count property, which is a number. We will display these properties in the UI. There is also a setMessage1 method. This method assigns a value to the content property. We refer to the content property as this. In Example 2, we have our template. There are three buttons. Each has a click event handler set up via the click attribute.

The first button has a method assigned to the click attribute.

We reviewed the setMessage1 method in the first example. This allows us to see in the UI that the first button was clicked.

The second button takes a different approach: it sets the value of the content property directly. This approach is perfectly fine, but somewhat limited; you can only accomplish one thing. The third button takes the same approach, but instead of setting the content property, it increases the count property.

Just keep in mind that the first approach is limited in that you can only accomplish one task when the element is clicked. The second approach, on the other hand, is more powerful; in the method that you assign to the click attribute, you can execute arbitrary code, which means that a limitless number of tasks can be accomplished.

I am trying to do some calculation but it is getting done as soon as I enter the amount. I just want this to happen on click of a button rather than automatically.

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes. Here's a JSBin example that demonstrates the above approach. The problem with this approach is the calculated result remains visible with the old value till the button is clicked.

To address this, you could hide the result whenever the quantity changes. This would involve updating the template to add an ng-change on the input, and an ng-if on the result:. These updates can be seen in this JSBin demo.
