PerformanceScriptTiming: sourceURL property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

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

The sourceURL read-only property of the PerformanceScriptTiming interface returns a string representing the URL of the script.

It is important to note that the reported function location will be the "entry point" of the script, that is, the top level of the stack, not any specific slow sub-function. See PerformanceScriptTiming.sourceFunctionName for more discussion around this.

Value

A string. Returns an empty string if the URL was not found.

Examples

See Long animation frame timing for examples related to the Long Animation Frames API.
