not able to update variable onkeyup javascript

Question

I have a textarea and i want to update a javascript variable onkeyup for textarea.

Here is my code:

 <textarea id="q" name="q"></textarea>
 <button onclick='alert(rec);'>
 Click
 </button>
<script>
var rec;

$("#q").keyup(function(){
      rec = document.getElementById("q").value;
});
</script>

i've implemented jquery , of course.

Actually your should also work, just set in JSFiddle to load JQuery lib as you are using it, and to append the script to the body element. — DDan

Try like this:

$("#q").keyup(function(){
      rec = $('#q').val();
});

Give this a try. You were just trying to call rec before it was set.

var rec = "";

$("#q").keyup(function(){
      rec = document.getElementById("q").value;
});

$("#showMe").on("click", function(){
console.log(rec);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<textarea id="q" name="q"></textarea>
 <button id="showMe">
 Click
 </button>

you forgot to put the # in front of the $("email").attr("href",email); Should be $("#email).attr("href", email);
