InterventionReportBody.lineNumber

The lineNumber read-only property of the InterventionReportBody interface returns the line in the source file in which the intervention occurred.

Note: This property is most useful alongside InterventionReportBody.sourceFile as it enables the location of the line in that file where the feature is used.

Syntax

let lineNumber = InterventionReportBody.lineNumber;

Value

An integer, or null if the line is not known.

Examples

In this example we create a new ReportingObserver to observe intervention reports, then print the value of lineNumber to the console.

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.sourceFile); // the source file
  console.log(firstReport.body.lineNumber); // the line in that file
}, options);
