Function iniframe try return window.self window.top catch e return true năm 2024

is a rectangular frame or region in the webpage to load or display another separate webpage or document inside it. So basically, an iFrame is used to display a webpage within a webpage. You can see more about iFrames here : HTML iFrames There may be a variety of reasons for checking whether a webpage is loaded in an iFrame, for example, in cases where we need to dynamically adjust the height or width of an element.

These are the following methods:

Comparing the object’s location with the window object’s parent location

Here, we simply compare the object’s location with the window object’s parent location. If the result is true, then the webpage is in an iFrame. If it is false, then it is not in an iFrame.

Example: In this example, we are using window object’s parent location.

javascript

function iniFrame() {

if (window.location !== window.parent.location) {

document.write(

The page is in an iFrame

Using window.top and window.self property

The top and self are both window objects, along with a parent, so check if the current window is the top/main window.

Example: In this example, we are using windows.top and windows.self property.

javascript

function iniFrame() {

if

The page is in an iFrame

document.write(

Using the window.frameElement property

Note that this only supports webpages belonging to the same origin as the main page in which it is embedded. The function window.frameElement returns the element (like iframe and object) in which the webpage is embedded.

Example: In this example, we are using windows.frame property.

javascript

function iniFrame() {

` `0

if ``3

document.write(

In the above code, store the element in which the webpage is embedded to the variable gfg. If the window isn’t embedded into another document, or if the document into which it’s embedded has a different origin (such as having been located from a different domain), gfg is null.
