[javascript] Get a Div Value in JQuery

I have a page containing the following div element:

<div id="myDiv" class="myDivClass" style="">Some Value</div>

How would I retrieve the value ("Some Value") either through JQuery or through standard JS? I tried:

var mb = document.getElementById("myDiv");

But the debugger console shows "mb is null". Just wondering how to retrieve this value.

---- UPDATE ---- When I try the suggestion I get: $ is not a function

This is part of a JQuery event handler where I am trying to read the value when I click a button. The handler function is working but it can't interpret the jQuery value it seems:

jQuery('#gregsButton').click(function() { 
   var mb = $('#myDiv').text();
   alert("Value of div is: " + mb.value); 
});

You could use

jQuery('#gregsButton').click(function() { 
    var mb = jQuery('#myDiv').text(); 
    alert("Value of div is: " + mb); 
});

Looks like there may be a conflict with using the $. Remember that the variable 'mb' will not be accessible outside of the event handler. Also, the text() function returns a string, no need to get mb.value.

You could also use innerhtml to get the value within the tag....

You can do get id value by using

test_alert = $('#myDiv').val();_x000D_
alert(test_alert);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="myDiv"><p>Some Text</p></div>

$('#myDiv').text()

Although you'd be better off doing something like:

var txt = $('#myDiv p').text();_x000D_
alert(txt);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="myDiv"><p>Some Text</p></div>

Make sure you're linking to your jQuery file too :)

your div looks like this:

<div id="someId">Some Value</div>

With jquery:

   <script type="text/javascript">
     $(function(){
         var text = $('#someId').html(); 
         //or
         var text = $('#someId').text();
       };
  </script> 

if you div looks like this:

<div id="someId">Some Value</div>

you could retrieve it with jquery like this:

$('#someId').text()
