Timed Page Refresh for FVS Templates

This document is applicable to users who have installed the FineVis Data Visualization plugin to learn plugin functions.

Application Scenario

When demonstrating an FVS template with highly real-time data, you may want to keep the template updated with the latest data. However, it is troublesome and inefficient to set Monitoring Refresh for components one by one. You can refresh the entire template by setting Timed Refresh.

Note:

You can view the effect at FanRuan Smart Business Park.

In an FVS template, click Template on the top bar of the designer and select FVS Template Setting. On the pop-up setting page, select Page Refresh.

• Enable Timed Refresh is deselected by default. You can select the checkbox and set Refresh Interval (six seconds by default; unit: seconds or milliseconds).

• The minimal refresh interval is one second (1000 ms), with no maximum limit.

• The refresh applies to all the pages in the template. After the refresh, the pre-refresh page rather than the first page is displayed.

Note:

For plugins of versions earlier than V1.7.2, this function can be implemented through the JavaScript codes under Template > Event After Page Load.

The following content shows the JavaScript codes.

setInterval(() => {
    duchamp.reload();
  }, 2 * 1000); // The refresh interval is 2000 ms, namely two seconds.

If a hyperlink with a dynamic parameter is used in the template (For example, Dynamic Parameter in Hyperlink is added to a cell of a table component), the parameter will be suffixed to the URL when you click the hyperlink with the dynamic parameter during the preview, as shown in the following figures.

Later timed refreshes do not trigger the clearance of the parameter suffixed to the URL. That is to say, the value linked with the dynamic parameter does not change with the timed refresh of the template.
