<h1>{{count}}</h1>

<p> This instance moves the mouse to the  DIV  Element, the variable is evaluated  "count"  Will automatically add  1 . </p>

</body>
</html>

Definition and usage

The ng-mouseover directives are used to tell AngularJS what to do when the mouse moves over the specified HTML element.

The ng-mouseover instruction does not override the element's native onmouseover event, and when the event is triggered, both the ng-mouseover expression and the native onmouseover event are executed.

Grammar

< element ng-mouseover="expression" > < /element >

All HTML elements support this instruction.
