Button enable and disable on click

Question

So I have this link to press

<a href="link" target="_blank">
    <div class="well">
        <span> blabla </span>
    </div>
</a>

and this button code in a page

<button  type="submit" class="btn-primary btn-lg" disabled="disabled"> Blabla </button>

And as you can see the button is disabled for now. How can I make that when I press that link the button to be enabled again? sorry for my bad English..

Answer 1

Try this generalized function for toggleDisabled

//Generalized function to make element toggleDisabled.
(function($) {
    $.fn.toggleDisabled = function(){
        return this.each(function(){
            this.disabled = !this.disabled;
        });
    };
})(jQuery);
//Code to use toggleDisabled
$(document).ready(function(){
  $("a").click(function(){
      $("button[type='submit']").toggleDisabled();
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="link" target="_blank">
    <div class="well">
        <span> blabla </span>
    <div>
</a> 
<br/>      
<button  type="submit" class="btn-primary btn-lg" disabled="disabled"> Blabla </button>
