选项：

• callback: function

  
  

  • Default empty function

  • Optionally define a callback function (in this case inline) that will do something with the callbackObject.newFrameHeight value. This can for instance be used with easyXDM to alert another domain that the frame has changed height.

  • Example:$('iframe').iframeAutoHeight({callback: function(callbackObject) { alert(callbackObject.newFrameHeight);} });

  • you can also access the current iframe jquery wrapper object use the this keyword

  • for example:callback: function(callbackObject) { alert(callbackObject.newFrameHeight + " and the iframe href is:" + $(this).attr('src')); }

• debug: boolean

  
  

  • Default is false

  • Will log some internal information to the console, if available

  • Example: $('iframe').iframeAutoHeight({debug: true})

• heightOffset: integer

  
  

  • Default is 0

  • Unit is pixels

  • Optionally add some buffer to the bottom

  • Example: $('iframe').iframeAutoHeight({heightOffset: 20});

• minHeight: integer

  
  

  • Default is 0

  • Unit is pixels

  • Sets the iframe height to this value if the calculated value is less

  • Example: $('iframe').iframeAutoHeight({minHeight: 200});

• animate: boolean

  
  

  • Default is false

  • Uses jquery animate with duration of 500 when resizing the iframe

  • Example: $('iframe').iframeAutoHeight({animate: true});

• resetToMinHeight: boolean

  
  

  • Default is false

  • hard set the iframe height to the minHeight before re-sizing

• triggerFunctions: Array of functions

  
  

  • Default is an empty array

  • Optionally define 1 or more functions that will have access to the resize method

  • can be used to resize the iframe from external events such as click or window resize - see examples below

• heightCalculationOverrides: Array of 2 element arrays

  
  

  • Default is an empty array

  • Optionally re-define the height calculation method(s)

  • override the default implementation or just override specific browsers

  • Example:$('iframe').iframeAutoHeight({strategyOverrides: [{ browser: 'mozilla', calculation: function () { return 2000; }}]);

  • The browser key should be one of 'webkit', 'mozilla', 'msie', 'opera' or 'default', seehttp://api.jquery.com/jQuery.browser/

  • The calculation key should be a function, usually with the signature(iframe, $iframeBody, options, browser)

  • see more examples below
