Is there a way to fix the issue of values from Textareas with multiple lines not getting parsed correctly in Webflow Logic when posting to an external API?

Yes, there is a way to fix the issue of values from textareas with multiple lines not getting parsed correctly in Webflow Logic when posting to an external API.

When you submit a form in Webflow, the values from textareas with multiple lines are by default encoded as URL-encoded strings, which means that line breaks are converted to %0D%0A (carriage return and line feed) characters. This can cause problems when sending these values to an external API that doesn't expect or handle URL-encoded strings.

To resolve this issue, you can use JavaScript to capture the form submission event, prevent the default behavior, and then manually parse the textarea values before sending them to the API. Here's an example of how you can achieve this:

1. Open the page in Webflow Designer where the form exists.
2. Select the form element and go to the Settings panel on the right-hand side.
3. Under the Actions section, add a new custom attribute called "onsubmit" and set its value to a JavaScript function call, for example: "processForm(event)".

Now you need to add the JavaScript code:

1. Go to the Page Settings in the Webflow Designer.
2. Under the Custom Code tab, add the following JavaScript code:

```

```

In the example code above, we define the `processForm` function which is called when the form is submitted. Inside the function, we prevent the default form submission behavior using `event.preventDefault()`. Then, we retrieve the textarea element by its ID and get its value. Next, we modify the value as needed using JavaScript string manipulation methods. In this case, we use the `replace` method with a regular expression to replace all line breaks (carriage return, line feed, or a combination of both) with a space. Finally, you can proceed to send the processed value to the external API using your preferred method (e.g., fetch, AJAX).

By manually processing the textarea values in this manner, you can ensure that the line breaks are transformed in a way that is compatible with the expectations of the external API you are integrating with.
