See if input and span is the same

See if input and span is the same

Hi,

I have following html:

 <span id="results">xxxx</span>

  <input id="input_here" type="text"name="UserInput"></input>

If #results has the same value as input_here I would like to alert a message. 
If there would be two inputs there wouldnt be any problem.  
But if results have for example the value 5 and I put in 5 into input_here I want an alert.
I have tried to do different if else  but can't get it to work.

if(parseInt($("#input_here").val()) ==  $(parseInt("#results").html()) {
 {
$("#used").html("number already used");
} else {
$("#guess").html("....");

}

}
});

Kinda new with Jquey and javascript so would appreciate some help. 
thx
