Properties
| Name | Description |
|---|---|
| Duration | Gets the duration of the script, including the microtasks that ran after it. |
| EntryType | Gets script. |
| ExecutionStart | Gets the time the script started to execute (after its compilation), or 0. |
| ForcedLayoutDuration | Gets the time spent updating the layout synchronously while the script ran: always 0, the library does not measure it. |
| ForcedStyleAndLayoutDuration | Gets the time spent recalculating the styles and updating the layout synchronously while the script ran: always 0, the library does not measure it. |
| ForcedStyleDuration | Gets the time spent recalculating the styles synchronously while the script ran: always 0, the library does not measure it. |
| Invoker | Gets what invoked the script: the URL of a script block, the target and the type of an event (e.g. IMG#id.onload), the name of a callback (e.g. FrameRequestCallback, TimerHandler:setTimeout), or the promise of a reaction (e.g. Promise.then). |
| InvokerType | Gets how the script was invoked: a script block, an event listener, a callback or a promise reaction. |
| Name | Gets script. |
| PauseDuration | Gets the time the script was paused by a synchronous operation (e.g. a synchronous XMLHttpRequest). |
| SourceCharPosition | Gets the position (0-based) of the code in its script, or -1. |
| SourceColumn | Gets the column (1-based) of the code in its script, or -1. |
| SourceFunctionName | Gets the name of the function of a callback or an event listener, or the empty string. |
| SourceLine | Gets the line (1-based) of the code in its script, or -1. |
| SourceUrl | Gets the URL of the script that defines the code, or the empty string. |
| StartTime | Gets the time the script started, in milliseconds relative to the time origin of the window of the long animation frame. |
| Window | Gets the window of the realm of the script, or null when its document is no longer fully active. |
| WindowAttribution | Gets the relation between the window of the script and the window of the long animation frame. |
