The get inner html function of jquery is .html and if you want to execute the function do .html(), so it returns the inner html. In your case, if you want to get the value of your textarea, use the jquery function .val() Your modified code:

function update()
{
  var temp = $('#textareaid').val();
  alert(temp);
}

Here you can find the API of the jQuery .val() : http://api.jquery.com/val/ and the API of the jQuery .html() : http://api.jquery.com/html/

Short explanation:
In javascript you define a function like a variable:

var a = function(params) {
  //do something
}

if you want to alert the value of this variable call alert(a); and alert tries to display the value (you get the function-definition). To execute your function you have to call alert(a(params)); and here you can pass some parameter.
