For a requirement I had to override the config of the configurable.js script that is initialised inside configurable.phtml, this one specifically:

<script type="text/x-magento-init">
            "#product_addtocart_form": {
                "configurable": {
                    "spConfig": <?= /* @escapeNotVerified */ $block->getJsonConfig() ?>,
                    "gallerySwitchStrategy": "<?php /* @escapeNotVerified */ echo $block->getVar('gallery_switch_strategy',
                        'Magento_ConfigurableProduct') ?: 'replace'; ?>"

I did so with a plugin using the afterGetJsonConfig method and adding my data to that spConfig after loading the template with ajax. Everything looks good when calling the template the first time, but I need to change and keep those changes to the configuration of the component after a validation via an ajax call. The problem is that, because the template is cached, it will always return the initial content.

This is confirmed by the fact that if I disable block_html cache the content is updated correctly and if I turn the cache on it doesn't and it doesn't even call then afterGetJsonConfig method on successive page reload. Is there a way to force disable the cache or get the most updated content and retain it without being forced to disable the cache for the whole page?


did you found the solution?I also want do this.


Try adding cacheable="false" argument to the block that you have assigned the .phtml template in your layout .XML file

<block class=".." name="..." template="..." cacheable="false" />

This will remove the block from the caching list, basically.

yes.you code should be ok.but I want cache it.and if has updated in backend,I want update "spConfig": getJsonConfig() ?>,then after visit the product page,it need cache the data again.
