ProgressEvent.initProgressEvent()

Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.

Non-standard
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The ProgressEvent.initProgressEvent() method Initializes an animation event created using the deprecated Document.createEvent("ProgressEvent") method.

ProgressEvent created that way are untrusted.

Note: this method has been dropped during the standard process. It has been deprecated and removed from most implementation. Do not use it anymore, use the standard constructor, ProgressEvent(), to create a synthetic ProgressEvent

Syntax

Progress.initProgressEvent(typeArg, canBubbleArg, cancelableArg, lengthComputable, loaded, total);

Parameters

typeArg
Is a DOMString identifying the specific type of animation event that occurred. The following values are allowed:
Value Meaning
loadstart The operation has started.
progress The operation still is in progress.
error The operation failed and didn't complete.
abort The operation was cancelled and didn't complete.
load The operation completed.
loadend The operation stopped.
canBubbleArg
Is a Boolean flag indicating if the event can bubble (true) or not (false).
cancelableArg
Is a Boolean flag indicating if the event associated action can be avoided (true) or not (false).
lengthComputable
Is a Boolean flag indicating if the total work to be done, and the amount of work already done, by the underlying process is calculable. In other words, it tells if the progress is measurable or not.
loaded
Is an unsigned long long 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.
total
Is an unsigned long long representing the total amount of work that the underlying process is in the progress of performing. When downloading a resource using HTTP, this only represent the content itself, not headers and other overhead.
