DeprecationReportBody.columnNumber
The columnNumber
read-only property of the DeprecationReportBody
interface returns the line in the source file in which the deprecated feature was used.
Note: This property is most useful alongside DeprecationReportBody.sourceFile
and DeprecationReportBody.lineNumber
as it enables the location of the column in that file and line where the error occurred.
Value
An integer, or null
if the column is not known.
Examples
In this example we create a new ReportingObserver
to observe deprecation reports, then print the value of columnNumber
to the console.
let options = {
types: ['deprecation'],
buffered: true
}
let observer = new ReportingObserver(function(reports, observer) {
let firstReport = reports[0];
console.log(firstReport.type); // deprecation
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);
