How Can I Prevent HTML Encoding Loss When Reading Attributes from Input Fields?

HTML Encoding Loss When Reading Attribute from Input Field

When retrieving values from hidden fields for display in textboxes, it's common to lose HTML encoding during the process. To prevent this, jQuery's attr('value') method can be problematic.

To solve this issue, leveraging a JavaScript library or jQuery method for HTML encoding is crucial. One such method is 'htmlEncode', which enables the retention of literal ampersands (&) within the retrieved value.

Here's an example implementation in JavaScript:

function htmlEncode(value){
  return $('<textarea/>').text(value).html();
}

By utilizing this function, the HTML encoding is preserved, ensuring that the value retrieved from the hidden field remains encoded, as intended.
