Javascript首先不工作，但在第二，第三等工作時間

Question

Javascript首先不起作用，但在第二，第三等時間工作。

;(function ($, window, document, undefined) { 

$variation_form = $('.variations_form'); 

$variation_form.on('show_variation', function(event, variation){ 

    if (variation.variation_description) { 
     $('.variation-description p').html(variation.variation_description); 
    } 
}) 
.on('reset_image', function() { 

    $('.variation-description p').html(''); 
}); 

}）（jQuery，window，document）;

Answer 1

你需要的東西來激發的事件.....

$(".myselector").on('click', function() { 
    $variation_form.trigger('show_variation'); 
}); 

Working Fiddle (again)：下面 全部代碼爲P ...

(function($){ 
    $(function(){ 

     $variation_form = $('.variations_form'); 

     $variation_form.on('show_variation', function (event, variation) {     
      if (variation.variation_description) { 
       $('.variation-description p').html(variation.variation_description); 
      } 
     }); 

     $variation_form.on('reset_image', function() { 
      $('.variation-description p').html(''); 
     }); 

     $(".myselector").on('click', function() { 
      $variation_form.trigger('show_variation'); 
     }); 
    }); 
})(jQuery);
