Question

So far I know two ways to pass php variables to javascript.
One is by using

<script>  
      $(document).ready(function()
          phpvalue=$("#hiddeninput").val()

      })
  </script>

<input type="hidden" id="hiddeninput" value="phpvalue">

And the other one is by having for example a button and using onclick

    <script>
       function clickf(phpvalue) {

       }
    </script>

<input type="submit" onclick="clickf(<?php echo phpvalue ?>)">

All of them work great but:

1. Is there any other way that I’m missing?

2. Which one is the “best”?

3. Any chance that I can use inside the script or the external js ?

Answer 1

<script>  
    $(document).ready(function()
        var phpvalue = <?php echo $var; ?>
    });
</script>
