XDomainRequest.onprogress
Deprecated
This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work 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.
This method is called periodically as an event handler for progress
events
on XDomainRequest
s, so that code can monitor progress while loading
content.
Note: While handling this event, you can look at
XDomainRequest.responseText
to get the response so far.
Once loading is complete, the XDomainRequest.onload
event handler gets
called.
Syntax
xdr.onprogress = funcRef;
Parameters
funcRef
- A function to call when
progress
events occur.
Example
var xdr = new XDomainRequest();
xdr.open("POST", "http://example.com/api/method");
xdr.onprogress = function(){
//Handle Partial Response with xdr.responseText
}
xdr.onload = function(){
//Handle Response with xdr.responseText
}
xdr.send("param1=value1¶m2=value2");
