What are iframe-resizer's main functionalities?
Automatic Resizing
This feature automatically resizes the iframe to fit its content. The `log: true` option enables logging for debugging purposes, and `#myIframe` is the selector for the iframe element.
const iFrameResize = require('iframe-resizer/js/iframeResizer');
iFrameResize({ log: true }, '#myIframe');
Height Calculation Methods
This feature allows you to specify different methods for calculating the height of the iframe. The `heightCalculationMethod` option can be set to various values like 'bodyScroll', 'documentElementScroll', 'max', etc. In this example, 'taggedElement' is used.
iFrameResize({ heightCalculationMethod: 'taggedElement' }, '#myIframe');
Message Passing
This feature enables sending messages from the parent page to the iframe. The `sendMessage` method is used to send a message to the iframe.
const iframe = iFrameResize({ log: true }, '#myIframe')[0];
iframe.iFrameResizer.sendMessage('Hello from parent');
Event Handling
This feature allows you to handle events such as resizing. The `resizedCallback` option is a function that gets called whenever the iframe is resized.
iFrameResize({
resizedCallback: function(messageData) {
console.log('Iframe resized:', messageData);
}
}, '#myIframe');
