jQuery（$（this）.parent（）发现不起作用

Question

I can't seem to get jquery find working on a product grid I have. Any idea how I can set it up?

<div id="sold-out" style="margin-top: 10px">
  <a class="grid-view-item__link grid-view-item__image-container" href=
  "/products/moringa-and-coconut-soap"></a>
  <form accept-charset="UTF-8" action="/contact#contact_form" class=
  "contact-form" id="contact_form" method="post" name="contact_form">
    <a class="grid-view-item__link grid-view-item__image-container" href=
    "/products/moringa-and-coconut-soap"><input name="form_type" type="hidden"
    value="contact"><input name="utf8" type="hidden" value="✓"></a>
    <p><a class="grid-view-item__link grid-view-item__image-container" href=
    "/products/moringa-and-coconut-soap"></a><a class=
    "product-page-notify-me notify-me" href="#" style="color: #788188;">Email
    me when available</a></p>
    <div class="clearfix notify-me-wrapper" style="display:none">
      <input class="styled-input" name="contact[email]" placeholder=
      "your@email.com" required="required" style="float:left; width:100%;"
      type="email" value=""> <input name="contact[body]" type="hidden" value=
      "Please notify me when Moringa and Coconut Soap becomes available.">
      <input class="btn styled-submit" style="float:left;" type="submit" value=
      "Send">
    </div>
  </form>
</div>

Javascript code:

jQuery('.notify-me').click(function() {
  alert('hello');
  jQuery($(this).parent().find('.notify-me-wrapper').fadeIn());           
  return false;
});

The code on my other page however, which targets one item, is working fine:

jQuery('#notify-me').click(function() {

jQuery('#notify-me-wrapper').fadeIn();           

return false;
} );

Answer 1

The parent of .notify-me is the p element and this element does not contain any descendant with the calss notify-me-wrapper

You might want to use closest , that way you can search for the closest ancestors for which you are sure that it contains the element with the class notify-me-wrapper :

$(this).closest('.contact-form').find('.notify-me-wrapper').fadeIn()

jQuery.closest() :

For each element in the set, get the first element that matches the selector by testing the element itself and traversing up through its ancestors in the DOM tree.

Answer 2

The parent of .notify-me is a p tag (paragraph) and the element you are looking for is the next sibling. Hence, change :

jQuery($(this).parent().find('.notify-me-wrapper').fadeIn());    

with:

jQuery($(this).parent().next('.notify-me-wrapper').fadeIn());

Change .find() with .next() .
