title: how to insert value in input, with javascript
body: <p>So I tried to do something like this -</p>
  
  <pre><code>$('#price').val(price);
  </code></pre>
  
  <p>price is 300, and it shows good on browser, in input field, but when I want to take it out and mail it with PHP, in $_POST['price'] it doesn't show up, How can I insert something in inputs value with JavaScript, so I can mail it? It seems this is not an insertion in value, but just a feature to display something, correct?</p>
