I want to send a php variable when calling a javascript function.
Thus: 

href="javascript:calcular($valor1)"

I try to do this, it doesn’t seem to work. Is there some other way to do this?

Just print the variable using the function echo 

href="javascript:calcular(<?php echo $valor1; ?>)"

  • It still doesn’t pass. I created a function just for testing purposes: function calcular(cod){ alert(cod);} and it didn’t work that way.

Hello, I would do so:

function calcular(element){
  var variavel = $(element).data('var');
}
<a data-var="<?= $calcular ?>" onClick="calcular(this)">Clique</a>
