QUESTION
I have been working on adjusting iframe height automatically.
The solutions with the problem are not working in React Hooks.
I have read Setting iframe height to scrollHeight in ReactJS and Adjust width and height of iframe to fit with content in it. I have explored additional posts and tried several times for almost a week. However, I have not found a proper way to figure this out.
I simplified what I have tried. My code
Apart from my code, I also tried iframeResizer.min.js
, yet it is not working. I believe it is because react generates dynamically. I found iframe-resizer-react
and tried but I have not found a way to solve it.
Can anybody have the same situation? How can I adjust iframe height automatically in React Hooks?
...ANSWER
Answered 2021-Apr-22 at 18:39from Setting iframe height to scrollHeight in ReactJS :
Use the onLoad() handler from the iframe to ensure that the content has loaded before you try to resize it - if you try to use React's lifecycle methods like componentDidMount() you run the risk of the content not being present yet.
QUESTION
I'm trying to to loop through 162 links of country rankings on a JavaScript page and click in and out of each country. For the first 13 or so country links they work, but once I get to around Belgium (give or take), I'm hit with ElementClickInterceptedException: Message: element click intercepted: Element . Earlier in the script I handled an iframe, but I'm not sure what I need to know and do in order to find and switch to an iframe in this loop should an iframe arise. Here's my code:</p>

I wanted to implement custom play/pause buttons on youtube iframe in a React project but, couldn't achieve it! It returns all type of errors like: When I press my custom mute button, it gives: player.mute is not a function
and so on.
Here is the code I am using:
ANSWER
Answered 2021-Apr-14 at 17:53Your code is running inside the App component render.
when doing stuff that needs to modify the DOM or relies on an element rendered by the component being present in the DOM you should use the useEffect
hook.
You can in this case move the setup code into a useEffect
and set the player using the useState
hook.
This way you ensure the iframe is mounted and the references will be right.

ANSWER
Answered 2021-Jan-14 at 10:03I am no wordpress pro so I am not sure where you add scripts, css and such. But to get this working.
Since I don't have your code I will try go through steps from basics to fix.
- Make sure you have the iframeResizer.min.js script included on the wordpress site. (just getting basics out of the way)
- As you write in your question make sure that the iframeResizer.contentWindow.min.js is on your google application site. (looks good as you write)
- Add small script to initialize like:
(Log not needed but gives some info to console)
I think you have these basic steps done. This normally should work in base cases but I assume it does not. The most likely issue is how height is calculated for your application. So next try change the heightCalculationMethod property to try different methods of resizing.
For example change your init script to:

I want to detect my changes in my ReactApp and want to apply those changes in Html page which is opened via Iframe.
Scenario: I want to use PostMessage handler to update my selected/changed data into my already open html page.
I tried this with "window.postMessage" and "window.AddEventlistener" but my changes are not reflecting here. What I need to change to make this work. Any suggestion?
//test.html
...ANSWER
Answered 2021-Jan-05 at 15:32You need to use the "window" of the iframe, not the main window
object when calling postMessage()
.
Considering ifr
is a variable referencing the iframe element in (HTMLIFrameElement), its window is defined in ifr.contentWindow
, so the call would be something like

For some reason HTMLPurifier seems to be removing the allowfullscreen element from iframes and I'm not sure why, I've done some research and can't seem it find an answer that isn't several years old. Below is how I initiate my purifier.
...ANSWER
Answered 2020-Jun-09 at 17:40"allowfullscreen" is not an attribute HTML Purifier inherently recognises for IFrames, which means that if you want to support it, you will need to customise your HTML Purifier module. Something like this should do it (this code was not tested, but should set you on the right path):
QUESTION
I have a parent component with two buttons. Button 1 should open iFrame with url 1 and button 2 url 2. It seems the way I built it the iFrame is not rebuilt entirely.
parent.js
...ANSWER
Answered 2020-May-22 at 21:20You have 2 options I can see to get this working:
- You need to leave the meeting before joining a new one. Unfortunately this method is complicated by daily taking about 7ms (in an async manner) to leave a meeting. So, it isn't possible to just have the
useEffect
clean up normally. It's also fun becausedaily.leave()
returns a promise that never resolves if you aren't in a meeting. Their documentation forleave()
is currently misleading:
Leaves the meeting. If there is no meeting, this method does nothing.
Returns null;

QUESTION
I have created a GUI allowing to play a Video file. I use a uicontrol
to create a slider, it works on basic use cases (when I click relatively slowly on the slider).
If I hold my mouse left button on the right arrow of the slider for a certain time, MATLAB will return an error(saying it cannot read the frame) on the line reading the frame of the video.
I guess the machine does not have the time to process the video at high pace, is there a way to solve this problem ?
Here is my code.

Answered 2020-Mar-18 at 23:12I can't test the solution, but you may try adding a flag that prevents the callback execution when it's already running:
