Check if textbox has empty value

Question

I have the following code:

var inp = $(\"#txt\");

if(inp.val() != \"\")
// do something

Is there any other way to check for empty textbox

Answer 1

Also You can use

$value = $("#txt").val();

if($value == "")
{
    //Your Code Here
}
else
{
   //Your code
}

Try it. It work.

Answer 2

The check can be done like this:

if (!!inp.val()) {

}

and even shorter:

if (inp.val()) {

}
