- // values. It will try to read the value from the form node's
- // method, then try this argument. If neither one exists, then it
- // defaults to POST.
- // handleAs: String?
- // Specifies what format the result data should be given to the
- // load/handle callback. Valid values are: text, html, xml, json,
- // javascript. IMPORTANT: For all values EXCEPT html and xml, The
- // server response should be an HTML file with a textarea element.
- // The response data should be inside the textarea element. Using an
- // HTML document the only reliable, cross-browser way this
- // transport can know when the response has loaded. For the html
- // handleAs value, just return a normal HTML document. NOTE: xml
- // is now supported with this transport (as of 1.1+); a known issue
- // is if the XML document in question is malformed, Internet Explorer
- // will throw an uncatchable error.
- // content: Object?
- // If "form" is one of the other args properties, then the content
- // object properties become hidden form form elements. For
- // instance, a content object of {name1 : "value1"} is converted
- // to a hidden form element with a name of "name1" and a value of
- // "value1". If there is not a "form" property, then the content
- // object is converted into a name=value&name=value string, by
- // using dojo.objectToQuery().
