InterventionReportBody: columnNumber property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Note: This feature is available in Web Workers.
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The columnNumber 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 and InterventionReportBody.lineNumber as it enables the location of the column in that file and line where the feature is used.
Value
An integer, or null if the column is not known.
Examples
In this example we create a new ReportingObserver to observe intervention reports, then print the value of columnNumber to the console.
const options = {
types: ["intervention"],
buffered: true,
};
const observer = new ReportingObserver((reports, observer) => {
const 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
console.log(firstReport.body.columnNumber); // the column in that file.
}, options);
