Interface ProgressEvent

All Superinterfaces:

Event

All Known Implementing Classes:

ProgressEventImpl

public interface ProgressEvent
extends Event

The ProgressEvent interface represents events measuring progress of an underlying process, like an HTTP request (for an XMLHttpRequest, or the loading of the underlying resource of an <img>, <audio>, <video>, <style> or <link>).

Method Summary

Modifier and Type	Method	Description
boolean	getLengthComputable()	The ProgressEvent.lengthComputable read-only property is a Boolean flag indicating if the resource concerned by the ProgressEvent has a length that can be calculated.
Double	getLoaded()	The ProgressEvent.loaded read-only property is an integer representing the amount of work already performed by the underlying process.
Double	getTotal()	The ProgressEvent.total read-only property is an unsigned 64-bit integer value indicating the total size of the data being processed or transmitted.

Method Details

getLengthComputable

boolean getLengthComputable()

The ProgressEvent.lengthComputable read-only property is a Boolean flag indicating if the resource concerned by the ProgressEvent has a length that can be calculated. If not, the ProgressEvent.total property has no significant value.

• ProgressEvent.lengthComputable - MDN
• ProgressEvent.lengthComputable - XMLHttpRequest

getLoaded

Double getLoaded()

The ProgressEvent.loaded read-only property is an integer representing the amount of work already performed by the underlying process. The ratio of work done can be calculated with the property and ProgressEvent.total. When downloading a resource using HTTP, this only represent the part of the content itself, not headers and other overhead.

See Also:

• ProgressEvent.loaded - MDN
• ProgressEvent.loaded - XMLHttpRequest

getTotal

Double getTotal()

The ProgressEvent.total read-only property is an unsigned 64-bit integer value indicating the total size of the data being processed or transmitted. In the case of an HTTP transmission, this is the size of the body of the message (the Content-Length), and does not include headers and other overhead.
