title: JQuery check if at least one input is filled (not empty & not zero)
body: <p>Can't figure out how to check if at least one input is filled which means it is not empty and the value is greater than zero. </p>
  
  <p>I can check it for <strong>empty</strong> value or <strong>zero</strong> but I want to check for both values.</p>
  
  <p>Tried to put <strong>&amp;&amp;</strong> after <code>value!=""</code> which didn't work.</p>
  
  <pre><code>$('#id_calculator_form').find(':input[value!=""]').not('#id_postcode'){
  
  }
  </code></pre>
