Bro I literally too confusing how to change light mode to dark. Because I make a nav bar for every page and button who change mode but when I used then it not changed so I used this method to send data I thought that it's work with local storage data without reload website.
Thank you!!! You helped me figure something out I was working on for four hours. This enabled me to understand multiple codes I was working with. Thank you!
Meu amigo gringo, muito obrigado! Sua solução é simples e fácil de implantar. Parabéns!
This is for the Same-origin Iframe only... You can't access from the different domain using the method explained in this video
Is there any way to do the same for different domains ?
Just use postMessage with all origins (*) and event listener to receive the message and you are all set.
@@marcelo.victor Can you clarify
?
@@badmuskaybee5111 on the child you add a event listener on page load to get this page height (document.body.scrollHeight) and pass it via postMessage (accepting all URL origins using * in message) to the parent page, that have a script with a window event listener to get that message and then apply that height passed to the style.
You are the best javascript programmer in the world. Thank you very much 🌹
I like the typing sound effects. Sounds real af
it might be real, I think its a mechanical keyboard
Fool
This example shows that will only work for local pages however if you link the to another link it will be dom exception for x-frame error
What if the origin of the is at a different origin, i.e. not local to the page? Is something similar possible that yeilds the same outcomes?
This channel has solution for almost every problem
An that's why I love the channel
Perfect, to the point video.. Thanks
Thank you for this great video. Can you post a version with an onload-execution? As soon as the script is loaded, some JS-code should be executed.
Hi, please could you do a video showing how to use Javascript to change content inside every 5s? That would be very helpfull
This is ok, when pages are from same source,but how to do that if we embed in some other website? Can we manipulating with objects of that?
how?
Anyone Reply?
@@pradeepkumarrana5651 it's not possible
There is the pointer-events CSS property you can use, however, when used, the s are ignored by all the mouse events, meaning your window mousemove events will be detected even when hovered over the , but you will not be able to interact with the anymore, this isn't the perfect solution, but in certain situations this may be just good enough to solve your problems, if you want for example to be able to drag an element around your page and want to prevent s from canceling your mousemove event you can change the pointer-events property for s every time the element is being dragged and change it back after it is dropped.
This is not working for me. Its saying "blocked a frame with origin null from accessing a cross origin frame" even though both the files are in the same folder
Great video man
