Title
Body
I am trying to simply check if I have an empty input text box but I get this error when I run this in Chrome: Uncaught TypeError: Cannot read property 'length' of undefined. Here is how I go about doing it. I check for DOM readiness and then call the function: function walkmydog() { //when the user starts entering if(document.getElementById('WallSearch').value.length == 0) { alert("nothing"); } } if (document.addEventListener) { document.addEventListener("DOMContentLoaded", walkmydog, false); }
