1 Answer 1


The data you are looking for 'QTY' on Checkout page. That comes by knockoutJS in Magento 2. Knockout basically bind data to HTML template and serves dynamic content.

If you can check "Application" Tab (F12), In Local Storage > Mage-Cache-Storage > Cart (Section Data) driven from Knockout. You can see QTY, Options and all other parameters there.

If you want to check QTY data, please check below file.


I hope that helps. Let me know if you have another questions regarding this.

  • Hello, if I want to find the value of qty? where should I look into? <span class="value" data-bind="text: $parent.qty"></span>. I did change the value, From the F12, it show qty:123 , however the frontend not showing the same, unless I get the wrong parameter.

  • How did you change the value? Can you please explain in detail? Commented Jan 29, 2020 at 18:26
  • I just hard code the return value. It did show at the value that I hard coded at cache-storage (F12), but the frontend still showing the old value. so I believe that "$parent.qty" is not referring the value at the Mage-Cache-Storage->cart->items-> qty...now I have no idea where I should trace where that qty come from.

  • What do you want with QTY? Commented Jan 29, 2020 at 18:38
  • I found out that my bundle products QTY not display correctly there, it always show 1 item, however, order and details summary is correct. I am also using ewave "Configurable Products In Bundles" extension as well, want to see where it goes wrong, it just like counting 1 bundle product, instead of their real qty
