Get pages and visuals

  • Άρθρο

After loading a report, you can make a list of pages or visuals that can be directly used to make changes to those instances. You can also create a list to see what visuals are used on a specific page.

How to get a list of pages

The Page class includes properties and methods to a change report page. For example, you can use the defaultSize property to define the page size as saved in the report, or the getFilters() method to get all page level filters in the report. For more information, see Page class.

Use getPages to retrieve a list of the pages in the report. The order of pages returned is in the same order as in the report.

let pages = await report.getPages();

How to get a list of visuals

The VisualDescriptor class includes properties and methods to change a visual in a specific page. For example, you can use the layout property to define the visual's position, size, and visibility. For more information, see VisualDescriptor class.

Use the getVisuals async method on the page instance.

let pages = await page.getVisuals();

Code examples

Retrieve the page collection

The following code example shows how to retrieve a page collection in report, with an example output showing the page name and display name of each object.

let pages = await report.getPages();
let log = "Report pages:";
pages.forEach(function (page) {
    log += "\n" + page.name + " - " + page.displayName;
});

console.log(log);

Get a list of visuals

This code example shows how to get a list of visuals for the first page.

let pages = await report.getPages();

// Retrieve the first page.
let firstPage = pages[0];
let visuals = await firstPage.getVisuals();
console.log(visuals);

Get the page collection and the visuals of the first page

This example retrieves the page collection and the visuals (with several properties) for the active page.

let activePage = await report.getActivePage();

let visuals = await activePage.getVisuals();
console.log(
    visuals.map(function (visual) {
        return {
            name: visual.name,
            type: visual.type,
            title: visual.title,
            layout: visual.layout
        };
    }));

Considerations and limitations

The report must be loaded in order to use the getPages or getVisuals functions.
