Connection Manager Release Notes
|
|
|
|
*** version 0.12.1 ***
|
|
|
|
* connection-debug.js corrected and synchronized with connection.js. Code
|
|
inconsistencies between the two files existed in 0.12.0.
|
|
|
|
*** version 0.12.0 ***
|
|
|
|
* When uploading files via setForm() and asyncRequest includes a POST data
|
|
argument, appendPostData() will create hidden input fields for each postData
|
|
label/value and append each field to the form object.
|
|
|
|
* setForm() returns the assembled label/value string of the parsed HTML form
|
|
fields.
|
|
|
|
* NOTE: Opera 9.02 does not allow for more than 12 concurrent Connection Manager
|
|
objects.
|
|
|
|
The following example creates 12 requests in a loop:
|
|
for(var n=0; n<=12; i++){
|
|
conn[n] = YAHOO.util.Connect.asyncRequest('GET', sUrl, callback);
|
|
}
|
|
|
|
If n > 13, Opera 9.02 will crash. Connection manager objects count n must be <=
|
|
12 at all times. This condition was not present in Opera version 9.01.
|
|
|
|
This condition does not apply to other A-Grade browsers (
|
|
http://developer.yahoo.com/yui/articles/gbs/gbs_browser-chart.html)
|
|
|
|
*** version 0.11.3 ***
|
|
|
|
* YUI Event dependency for file uploading is now optional.
|
|
|
|
* uploadFile() now sets unique IDs for each file upload transaction to prevent
|
|
iframe collisions with parallel uploads.
|
|
|
|
* The callback object now has property responseXML to provide support for file
|
|
upload transactions that return an XML document.
|
|
|
|
* setForm() will verify if a select option value attribute is present and use
|
|
its value, including empty string, before using the text node value.
|
|
|
|
* Modified polling mechanism in handleReadyState() and
|
|
handleTransactionResponse() to prevent infinite polling if JavaScript errors
|
|
occur in the user-defined callback.
|
|
|
|
* createFrame() will now accept a boolean argument of true to set the frame
|
|
source to "javascript:false" to prevent IE from throwing security warnings in an
|
|
HTTPS environment.
|
|
|
|
* setHeader() now enumerates through the _http_header object using
|
|
hasOwnProperty() to prevent collisions with members added to Object via
|
|
prototype.
|
|
|
|
* If using setForm() and asyncRequest includes a POST data argument, the data
|
|
will be concatenated to the HTML form POST message.
|
|
|
|
*** version 0.11.2 ***
|
|
|
|
* No revisions.
|
|
|
|
*** version 0.11.1 ***
|
|
|
|
* uploadFile() now verifies the existence of callback.upload before invoking
|
|
callback, with or without object scope.
|
|
|
|
*** version 0.11.0 ***
|
|
|
|
* Each transaction can be defined with a timeout threshold, in milliseconds,
|
|
through the callback object. If the threshold is reached, and the transaction
|
|
hasn't yet completed, the transaction will call abort().
|
|
|
|
* abort() will now accept a callback object as the second argument. The
|
|
failure callback will receive a response object to indicate the transaction was
|
|
aborted.
|
|
|
|
* setForm() will now support file uploads by setting the second argument to
|
|
true (e.g., YAHOO.util.Connect.setForm(formObject, true). File upload does not
|
|
use the callback success or failure handler. Instead, it uses a new callback
|
|
object handler: upload.
|
|
|
|
* HTML form submit will no longer submit form fields without a defined name
|
|
attribute.
|
|
|
|
* The default POST header of 'Content-Type','application/x-www-form-urlencoded'
|
|
can be overridden by calling setDefaultPostHeader(false). This
|
|
will remove the default header from non-HTML form, POST submissions.
|
|
|
|
* setHeader() now enumerates through the _http_header object with
|
|
propertyIsEnumerable to prevent collisions with members added to Object via
|
|
prototype.
|
|
|
|
*** version 0.10.0 ***
|
|
|
|
* handleTransactionResponse() now treats the full HTTP 2xx range as a success
|
|
case, instead of just HTTP 200.
|
|
|
|
* To accommodate multiple field values in Mozilla/Firefox, multiple initHeader
|
|
calls with the same label will now result in the values concatenated to a
|
|
comma- delimited string value.
|
|
Example:
|
|
Setting Content-Type:'application/x-www-form-urlencoded' and Content-
|
|
Type:'text/xml' will result in Content-Type:'application/x-www-form-urlencoded,
|
|
text/xml'.
|
|
|
|
* Default polling interval lowered to 50ms.
|
|
|
|
* YAHOO.util.Connect.setPollingInterval() will allow you to set a polling
|
|
interval -- in milliseconds -- to override the default value.
|
|
|
|
* YAHOO.util.Connect.getResponseHeader[headerLabel] now supported as a response
|
|
object property to provide symmetry with the native XHR object's property.
|
|
Example:
|
|
YAHOO.util.Connect.getResponseHeader['Content-Length'] will return the value
|
|
for the Content-Length header, if the header is available.
|
|
|
|
* YAHOO.util.Connect.allResponseHeaders property renamed to
|
|
getAllResponseHeaders to provide symmetry with the native XHR object's
|
|
property.
|
|
|
|
* YAHOO.util.Connect.setForm() now supports HTTP GET as well as HTTP POST.
|
|
|
|
* YAHOO.util.Connect.setForm() now accepts an HTML form object as well as its
|
|
name attribute value.
|
|
|
|
* YAHOO.util.Connect.setForm() will not submit HTML form fields that are
|
|
disabled or do not have a name attribute value.
|
|
|
|
* [FIXED] Response exceptions result in infinite callback loop in
|
|
Mozilla/Firefox.
|
|
|
|
* [FIXED] YAHOO.util.Connect.abort() now properly clears polling interval.
|
|
|
|
* [FIXED] isCallInProgress() now verifies whether XHR instance still exists,
|
|
and returns false if the connection object is no longer available.
|
|
|
|
*** version 0.9.0 ***
|
|
|
|
* Initial release
