InterventionReportBody.lineNumber
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
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);
