跨域无效！

用法：

jQuery('iframe').iframeAutoHeight(); 设置所有的iframe

$('iframe.photo').iframeAutoHeight();指定的iframe

<!-- with document ready, most likely in the html head --><script> $(document).ready(function () { $('iframe').iframeAutoHeight({debug: true}); });</script><!-- inline, after the iframe --><iframe src="my_iframe.html" class="auto-height" scrolling="no" frameborder="0"></iframe><script> $('iframe.auto-height').iframeAutoHeight({minHeight: 240});</script>

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)
