Short description of issue
Free template recommendation product block customization (bundled sales) : Self-developed add to purchase button form submission no response (passing to shopping cart seems truncated)
Reproduction steps
I want to make custom modifications to the original code of the recommended product block under the free template to achieve the bundling sales function for similar related products. Now I have encountered a problem. I found that the add to cart button I wrote myself cannot be directly added to the cart in one click. The button I set uses the form submission method, but after clicking, the form submission has no response. That is to say, the form seems to be cut off during the process of being transmitted to the shopping cart. I don’t know how to write it?
Additional info
The template I used is the free Fabric 3.0.0 version.Below, I present the diagrams that respectively illustrate the button logic I have developed and the JavaScript code for the judgment.
