 ## Creating a Component
 
-Create a \<Web> component in the .ets file under main/ets/MainAbility/pages. Then, in the created component, use src to specify the web page URI to be referenced, and bind a controller to the component to call the component APIs.

 ## Adding Events and Methods
 
-Add the onProgressChange event for the \<Web> component, which is triggered when the loading progress changes and returns the progress value in its callback. Assign the progress value to the \<Progress> component to control the status of the component. When the progress reaches 100%, the \<Progress> component is hidden, and the web page loading is complete.

-Add the runJavaScript method to the onPageEnd event. The onPageEnd event is triggered when the web page finishes loading. In this case, the runJavaScript method can be used to execute JavaScript scripts in the HTML file. In the sample code below, when the web page finishes loading, the onPageEnd event is triggered to call the test method in the HTML file and print information on the console.

 ## Scenario Example
 
-In this example, you'll implement a \<Web> component where videos can be played dynamically. Embed a video resource into an HTML page, and then use the \<Web> component controller to invoke the onActive and onInactive methods to activate and pause page rendering, respectively. When the page is hidden, the \<Web> component stops rendering and the video playback pauses. When the page is displayed, the \<Web> component is activated and the video playback resumes.
