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);Specifications
