jQuery自动完成-在自定义div中显示结果

Question

I'm looking for some help in customizing the dropdown that displays the results of autocomplete. I have the following html which I want to use to display the results. The idea is that the div below is hidden to begin with and as soon there is a match, I make the div visible and each matched results would be wrapped in the < li > tag below.

<div class="search_dropdown_wrapper" style="display:none;">
    <div id="search_arrow" class="dropdown_pointer search"></div>
    <ul>
        <li>
            <img src="/assets/2c42cdf.jpg"  />
            <h4>Tom Jerry</h4>
            <p>Cartoon Characters</p>
        </li>
        <li>
            ...
        </li>
        ...  
    </ul>
</div>

The portion of my autocomplete code which works to display the results is..

  $('#search_name').autocomplete({
    minLength: 2,
    ...
    ...
  })
  .data( "autocomplete" )._renderItem = function( ul, item ) {
      return $( "<li></li>" )
      .data( "item.autocomplete", item )
      .append( "<a>" + item.name + "</a>" )
      .appendTo( ul );
  };

(FYI, the above thanks to How to set-up jquery-ui autocomplete in Rails )

At the moment I only have the name (item.name) displaying in the dropdown. How can I get the html I want into the code above. The part where I'm confused is how to get the div around the ul item which is being passed into the function. Thanks.

Answer 1

Use .parent() to get to the div around the ul: http://api.jquery.com/prev/

$(ul).parent()

Or, to grab the previous sibling: (as I somehow though you needed to do at first) http://api.jquery.com/prev/

$(ul).prev()

If ul is already a jQuery object, then you can just do ul.parent() and ul.prev()

Alternatively, you can access the wrapper div directly:

$('.search_dropdown_wrapper')

I might suggest adding an ID to that wrapper and accessing it by ID, eg:

<div class="search_dropdown_wrapper" id="search_dropdown_wrapper">
...
</div>

Then in your script you can use $('#search_dropdown_wrapper') to access the div directly.

The direct access approach is safer. If you ever change your markup, it will still access the correct div (theoretically.)

Answer 2

Each item it is response objects collection. If in your reply the object has a field of the email access will be item.email. It is insert your autocomplete object into custom div with custom li tag:

$("#search_name").autocomplete({
  source: availableTags,
  open: function() {
    $(this).autocomplete("widget")
      .appendTo(".search_dropdown_wrapper")
      .css("position", "static");
    } 
}).data('ui-autocomplete')._renderItem = function(ul, item) {
   var html, paragraph;
   html = '<h4><a>' + item.name + '</a></h4>';
   paragraph = '<p>Cartoon Characters</p>';
   html = html + paragraph;
   return $('<li>').append(html).appendTo(ul);
};
