InterventionReportBody

The InterventionReportBody interface of the Reporting API represents the body of an intervention report (the return value of its Report.body property).

An intervention report is generated when usage of a feature in a web document has been blocked by the browser for reasons such as security, performance, or user annoyance. So for example, a script was been stopped because it was significantly slowing down the browser, or the browser's autoplay policy blocked audio from playing without a user gesture to trigger it.

Properties

id

A string representing the intervention that generated the report. This can be used to group reports by deprecated feature.

message

A string containing a human-readable description of the intervention, including information such how the intervention could be avoided. This typically matches the message a browser will display in its DevTools console when an intervention is imposed, if one is available.

sourceFile

A string containing the path to the source file where the intervention occurred, if known, or null otherwise.

lineNumber

A number representing the line in the source file in which the intervention occurred, if known, or null otherwise.

columnNumber

A number representing the column in the source file in which the intervention occurred, if known, or null otherwise.

Examples

let options = {
  types: ['intervention'],
  buffered: true
}

let observer = new ReportingObserver(function(reports, observer) {
  let firstReport = reports[0];
  console.log(firstReport.type); // intervention
  console.log(firstReport.body.id);
  console.log(firstReport.body.message);
  console.log(firstReport.body.sourceFile);
  console.log(firstReport.body.lineNumber);
  console.log(firstReport.body.columnNumber);
}, options);
