QUESTION
I successfully integrated the Stripe checkout in a Java web application.
I would like to have the email and name fields prefilled. According to the docs, I have to create a new customer and than pass it to the session. Here is the relevant part of code:
...ANSWER
Answered 2021-Apr-22 at 19:26This is happening because in the requestOptions for the Checkout session you are setting a connected account with setStripeAccount(CONNECTED_ACCOUNT_ID). THe customer creation does not have this, so the customer is being created on your platform account, not the connected account.
If you want to have the session on the connected account, you need to create the customer there too. You should add the same requestOptions with setStripeAccount(CONNECTED_ACCOUNT_ID) to your customer create request.

I am trying to make a slider for a list of products and I have placed a button on each side of the slider to slide the products. The problem I am facing is that it works fine when I press exactly at the buttons but when I press anywhere around it, it throws the error Uncaught TypeError: Cannot read property 'style' of null.
...ANSWER
Answered 2020-Dec-31 at 21:07You need to delegate and test what you clicked since you have two elements you can click, the button and the
Also you have duplicate IDs which is not allowed (had you used them)

QUESTION
I'm trying to combine multiple URLs parameters under one joined link. Console log registers all of the parameters, my issue is that stored value is overwritten and only last value is being printed as well as the number of printed parameters is not matching to the actual amount of URLs. I've included code below:
...ANSWER
Answered 2020-Dec-18 at 02:59As for only printing that last value, when you call text() every iteration then it overwrites whatever was previously in that element.
Following simplifies both reading existing params and generating combined ones by using URLSearchParams() API. It also generates an array of the values that are easily inserted in the
using join()

QUESTION
As you can see in my code I'm trying to get the material information by filling width and depth. For example, width:300 and depth:300 will result 90000. Then, if you write your result to other input you can get the material information.
I don't want to write result to another input to get this information. I just want to multiply width and depth and according to result, I'd like to see the material.
...ANSWER
Answered 2020-Dec-05 at 10:28If you want to get the material without the extra step, you can calculate the product of the two numbers and right after that find the item in your array. Once it's found, you can update the result.
I've created a snippet for you below. I've made a lot of changes:
- I've separated the HTML and JS parts.
- I've wrapped the inputs in a
form, and added labels for the inputs. - I've changed the input type to number (as these fields can only be numbers)
- I've renamed the
studentsarray toitems. - I've changed the
nameproperty tosizein your and it's no longer a string but a number, so it's easier to work with later. The product ofdepthandwidthis a number, so it's easier to compare to another number. - Instead of different button clicks, we're checking the form
submitevent by usingaddEventListener. This way, you can hit enter in any field, and submit the form. It's also easier to get the form fields by usingevent.target.elements. - I've removed unnecessary functions
- I've used object destructuring:
let { depth, width } = e.target.elements. - I've used template literals to write the HTML part in JS with variables.
