To pass an argument from an iframe to its parent, you can use the postMessage method in JavaScript. Here's how you can do it:
- In the child iframe:
1 2 |
// Send a message to the parent window
window.parent.postMessage('Hello parent!', '*');
|
- In the parent window:
1 2 3 4 5 6 7 8 9 10 |
// Add an event listener to listen for messages from the child iframe
window.addEventListener('message', function(event) {
// Check the origin of the message to prevent security issues
if (event.origin !== 'https://example.com') {
return;
}
// Log the message received from the child iframe
console.log('Message received from child:', event.data);
});
|
Make sure to replace 'https://example.com' with the actual origin of the child iframe. This will ensure that the message is only received from a trusted source.
By using the postMessage method, you can securely pass arguments from an iframe to its parent window in a controlled manner.
