Get page name when user switches to some other page in a report

You can add an event handler which will get called when the Report page is changed.

Please follow the below code snippets:

1. Create the embed configuration object for the report:

const embedConfig = {
        type: "report",
        tokenType: models.TokenType.AAD,
        accessToken: "ACCESS_TOKEN",
        embedUrl: "EMBED_URL",
 };

2. Get a reference to the HTML DIV element that contains the embedded report:

const embedContainer = $('#embedContainer')[0];

3. Embed the Report:

const report = powerbi.embed(embedContainer, embedConfig);

4. Add an event handler on the report object. Inside the event, you can assign the name property of the event object to the global variable:

report.on('pageChanged', event => {
    const page = event.details.newPage;
    globalVar = page.name;
});
