When you use it for cross domain fix, You must use postMessage function on page in iframe. (Click Here or Click Here for Details). Tutorial is below

You shouldn't use it on local because it doesnt work correctly in chrome (chrome gives cross domain error on local)

Cross-Domain and Watcher cannot work together. If you want to enable watcher, you cannot use crossdomain fix.

Cross Domain Tutorial

You can test it after upload "crossdomain_inpage.html" file (its in demos folder) to external server.

Firstly, you must upload this plugin to 2 server (base website and external server). After that, call " $.iframeHeightExternal();" function from external page. Tadaam! It finished. :)

Important thing is, if you change default options (in your base website), you must add your setting object to function ($.iframeHeightExternal()) that using on your external website. For Example;

when using it in your base website

$('#autoIframe').iframeHeight({
	debugMode : true,
	minimumHeight: 450,
	onMessageFunctionName: "dummyFunc"
});

then set it in your external site

$.iframeHeightExternal({
	debugMode : true,
	minimumHeight: 450,
	onMessageFunctionName: "dummyFunc"
});

If you want to trigger from any element to update iframe

var iframeExt = $.iframeHeightExternal({
	debugMode : true,
	minimumHeight: 450,
	onMessageFunctionName: "dummyFunc"
});
$('button').on("click", function(){ iframeExt.update(); });
