  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 DOMStringidentifying the specific type of animation event that occurred. The following values are allowed:Value Meaning loadstartThe operation has started. progressThe operation still is in progress. errorThe operation failed and didn't complete. abortThe operation was cancelled and didn't complete. loadThe operation completed. loadendThe operation stopped. 
- canBubbleArg
- Is a Booleanflag indicating if the event can bubble (true) or not (false).
- cancelableArg
- Is a Booleanflag indicating if the event associated action can be avoided (true) or not (false).
- lengthComputable
- Is a Booleanflag 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 longrepresenting the amount of work already performed by the underlying process. The ratio of work done can be calculated with the property andProgressEvent.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 longrepresenting 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.
