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.
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);
