And make sure correct quoting is used. Use HTML entity and escape sequence
if necessary.

Cause, the provided sample code will never work, regardless of what HTML
tag/element it is on.

<span> or <div> don't have a value. What are you talking about?

Using "value" is totally fine:

However - where exactly do you use "onClick" and did you define
"searchkey" as *id* and not only as name?

“span” or “div” elements do not have a built-in “value” property.

*That* should work, though, as the corresponding object *does* have a built-
in value property.

By contrast to the “innerHTML” property, the “textContent” property does not
require any escaping beyond the one required for a syntactically correct
ECMAScript program; indeed, if you HTML-escape the value assigned to it, the
escape sequences will be displayed verbatim.
