Question

The if(usern == “”) part of code is working. But when i pushed space button on keyboard for “input”, it goes to else statement. How can i fix this?

usern = $("input").val();

if(usern == "")
        //don't do 
else 
        //do something

Answer 1

Use $.trim() to remove the white space from the value first:

var usern = $.trim($("input").val());
