Getting undefined after if statement
So I am trying to get javascript/jquery to not execute if a text input is empty. I'm confused as to why I am getting undefined after I put an if statement after the element.submit();.
$(document).ready(function(){
$("#th_name").focus();
$("#th_name").blur(function() {
if($("#th_name").val() == "") {
document.getElementById("th_name").focus();
}
});
});
And the html
" id="th_add" enctype="multipart/form-data">
A:
Because the value is probably undefined or null you can use val()
if( $("#th_name").val() == "" )
