If you want to export your Kindle book highlights without the page location and color information, you can follow these steps:

• Export the content in any format you prefer.
• Paste the content in Visual Studio Code or any other text editor that supports regular expressions.
• Use the regular expression Highlight \(yellow\) - Location [0-9]+ in the Find and Replace tool to replace Highlight (yellow) - Location 01.
• Replace all the matches with an empty string.

This will remove the unwanted details from your highlights and leave only the text you want to keep.

The name attribute specifies the name of an <input> element. It is used to reference elements in a JavaScript, or to reference form data after a form is submitted to the server.

Only form elements with a name attribute will have their values passed when submitting a form.

<form action="http://localhost" method="POST">
    <label for="User">User name</label>
    <input type="text" id="User" name="Name" value="bino" />
    <input type="submit" value="submit" />
</form

When you submit the above, server localhost will recive a content like below:

Name=bino
