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.

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

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.

js
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);
