Greetings weweb folks.
I am new to weweb and not much of a coder. I am trying to build a shopping cart array.
Right now I have this array of list of items added to cart, the quantity and other details :
[
{name:product1, price:9.99, quantity: 2}
{name:product2, price:8.99, quantity:3}…
]
I am trying to figure out how I can change/update the quantity, without changing the order of items. Can you guys share how to it? Thank you so much.
You need to use a custom javascript action.
So, you enter code like this if your array variable is called array:
array[index].name = “product4”;
index is the number of the item in the array. Arrays start at 0 position, so the first item is array[0].
You can use dot notation like that to get or set the value.
Neither. Take out the return unless you want to return something.
Here, it sounds like you just want to set the value.
Thanks so much for your help, been figuring this since yesterday 
For information, we have developed a way to do it in no code, because lot of people need the feature.
When doing a “Change variable Value”, you will be able to choose a path and/or an index when modifying an array or object.
This will be on the next release 
you guys rock! Thank you so much for this
And its in production !
You can now update array and object partially with the “Change variable value” action
