Simple JavaScript code snippet to check whether or not a window is in an iFrame. Very useful for some functions that may make use of the URL in the address bar of the page.

Simple as this.

var isInIframe = (window.location != window.parent.location) ? true : false;

    This is pure javascript, why did you label it as jquery?

    • jquery4u

      @Yogi, labelled as jQuery for Google Search Keyphrase as some people search for jQuery even though a good solution sometimes lies with regular JavaScript.

      • Versitek

        if you want to try to fool search results in this manner, just put “not jQuery” in the title rather than deceiving the search engines. false H1 tags can get you a penalty in Google. However, using “not jQuery” will still turn up this as a result with that keyword without the penalty.

    I wonder if window !== window.parent works for this purpose across all platforms. It works in Chrome on OS X.
