Get the value inside element give me double \n in empty case

Question

I am using MVC 5 and html table to render a view. In one of the table cell, I want to check if the value inside the td tag is null or not and show or hide an item using JQuery. I am using the code below but for some reasons the value inside the tag is showing "\n \n" and therefore always not null. I have included a screen and my code. Any help to remove "\n \n" so I can check if the value is null or not will be appreciated.

 

 

$(document).ready(function(){
$("button").click(function()
{
var v = $("#hideheader").html(); ----> This value here is showing "\n \n"
if(v=='') --- This is always not empty
{
alert('empty');
$("#hide").hide();
}
else
{
alert('non-empty value');
}
});
});
<table>
<thead><tr> <th id="hide">ID</th></tr> </thead>
<tbody><tr><td id="hideheader">@item.adminstring</td></tr></tbody>
</table>
