htmll set element id code example

Example 1: js get id value

var element = document.getElementById("YourElementId");
var value_element = document.getElementById("YourElementId").value;

Example 2: html script id and class

<!--
	The script tag's id and class property work just like in any html tag.
	Possible use case is to add css styles to your script tag.

	Using e.g. 'class="createFunctionality" type="text/javascript"' in a
	script is a good practice if you use a editor,
	that displays the name of the script when collapsed,
	as part of documentation; e.g. Indicate what the script does.
	
	You can also view the source code of the script like this:
-->

<!-- Rememer to add jquery! -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>

<script class="foo" type="text/javascript">
	function foobar() {
	    var a = 1;
	}   
</script>

<div id="showScript">Show me the script.</div>

<script type="text/javascript">
    $('#showScript').click(function(event) {
        event.preventDefault();
        $("<div>").html($(".foo").text()).appendTo($("body"));
    });
</script>
