How to get character length of selected text with jQuery?

I need to select some text in a textarea with id="message" and then get the character count of that.

I'm assuming something with .length() is needed, but I'm not sure what it would require to actually get the selected text, and then use that to determine the length of it.

Thanks in advance

Try this:-

<textarea id="Editor"></textarea>
<input type="button" id="p" value="get text"/>

and in jquery:-

$('#p').on('click', function () {
var textComponent = document.getElementById('Editor');
var selectedText; 
var startPos = textComponent.selectionStart;
var endPos = textComponent.selectionEnd;
selectedText = textComponent.value.substring(startPos, endPos)    
alert("You selected: " + selectedText.length);
});

I think you are trying for this

$("#message").text().length;

Edit:

$("button").click(function(){
    var txt=document.getElementById("message");
    alert(txt.value.substr(txt.selectionStart, (txt.selectionEnd -txt.selectionStart)).length);
});
