Question

What is the best way to send text inputs to a hidden field on an HTML webpage?

Struggling with managing copy and paste functionality in my current application development project by guiding input into a hidden field. The issue arises when I apply visibility: hidden to the target field, as typing or pasting text into it doesn't seem to function properly. My approach involves utilizing a <textarea> element to capture the text and focusing on it using

document.select('textAreaID').focus()

, which works unless visibility is set to hidden via CSS.

Check out this fiddle demonstrating the behavior. Blue square captures focus, while red and green toggle visibility.

Is there an effective method to conceal the text area yet still enable pasting or typing into it? Alternatively, are there other techniques to redirect copying behavior to generate editable text chunks for parsing and manipulation?

(Note: There's some d3 code in the fiddle as I'm leveraging it for another purpose due to its convenient APIs.)

It seems that certain browsers do not allow focusing on elements that are set to visibility:hidden. While this behavior may vary across different browsers, I encountered an issue with Chrome: http://jsfiddle.net/ps6KK/

Given the limitations of visibility:hidden, we need to find a workaround to make the textarea appear hidden. One way to achieve this is by removing all dimensions such as height and width, while setting the background to transparent. You may also consider making the text color transparent if needed.

#textDiv {
  resize: none;
  padding: 0;
  height: 0;
  border: 0;
  width: 0;
  background: transparent;
}

Have you ever faced the challenge of storing text content when copying it (not pasting)? A simple solution is to utilize a global JavaScript variable instead of saving it in a hidden HTML element within an event handler function.
