I am seeing an
"Uncaught TypeError: $(...).value is not a function"
whenever I submit data, and I'm not sure why. I'm trying to send the data in the text field via POST to send.php.
Any help would be appreciated, thanks!

on if not a function" jQuery error occurs for 2 main reasons: Loading an old version of the jQuery library that doesn't support the on function. Loading a library that overrides the value of the dollar sign $ variable.
To solve the "$. ajax is not a function" error, add the regular jQuery script to the page and remove the slim version. The slim jQuery version does not include the ajax function.
This is a standard JavaScript error when trying to call a function before it is defined. This error occurs if you try to execute a function that is not initialized or is not initialized correctly. This means that the expression did not return a function object.
The JavaScript exception "is not a function" occurs when there was an attempt to call a value from a function, but the value is not actually a function.
There is no function named value in jquery.
{ chat_message: $('#m').value() }
It should be -
$('#m').val()
