title: JavaScript input validation with regex
body: <p>I want to validate my inputs, so the user can just enter letters. The problem is that it just checks one input field but I selected all with <code>:input</code></p>
  
  <p>code:</p>
  
  <pre><code>$('#formularID').submit(function() {
     var allInputs = $(":input").val();
     var regex     = new RegExp("[a-zA-Z]");
     if(regex.test(allInputs))
     {
         alert("true");
     }else
     {
         alert("false");
         return false;
     }
  });
  </code></pre>
  
  <p>I appreciate every help I can get!</p>
