XDomainRequest.onprogress - Web APIs 编辑

Obsolete

This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

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 XDomainRequests, 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&param2=value2");
