ReportingObserver()
constructor of the
Reporting API
creates a new
ReportingObserver
object instance, which can be used to collect and access reports.
new ReportingObserver(callback[, options]);
callback
ReportingObserver.observe()
). The callback function is given two parameters:
reports
: A sequence of
Report
objects representing the reports collected in the observer's report queue. This is probably the most common way to retrieve the reports.
observer
: A reference to the same
ReportingObserver
object, allowing for recursive report collection, etc.
选项
可选
ReportingObserverOptions
object allowing you to set the options for creating the object. The available options are:
类型
: An array of strings representing the types of report to be collected by this observer. Available types include
deprecation
,
intervention
，和
crash
(although this last type usually isn't retrievable via a
ReportingObserver
).
buffered
: a boolean that defines whether the reports that were generated before the observer was able to be created should be observable (
true
) 或不 (
false
).
let options = {
types: ['deprecation'],
buffered: true
}
let observer = new ReportingObserver(function(reports, observer) {
reportBtn.onclick = () => displayReports(reports);
}, options);
