jQuery Autocomplete使用extraParams传递其他GET变量 [英] jQuery Autocomplete using extraParams to pass additional GET variables

问题描述

我指的是JörnZaefferer的jQuery Autocomplete v1.1插件[来源:

I am referring specifically to the jQuery Autocomplete v1.1 plugin by Jörn Zaefferer [source: http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/] as there seems to be quite a few variations of this plugin.

我正在尝试在用户开始键入内容时将其他参数传递给服务器，因为我有多个字段要自动完成以提供建议.

I'm trying to pass additional parameters to the server when the user starts typing because I have multiple fields that I want autocomplete to provide suggestions for.

除了查询外，我还想将输入名称属性发送到服务器，但是我似乎无法在extraParams中使用$(this).attr('name').

In addition to the query, I want to send the input name attribute to the server but I can't seem to use $(this).attr('name') within the extraParams.

我的jQuery:

   $('.ajax-auto input').autocomplete('search.php', {
     extraParams: {
      search_type: function(){
       return $(this).attr('name');
      }
     }
   })

这是我的HTML.

 <form method="post" action="#" id="update-form" autocomplete="off">
  <ol>
         <li class="ajax-auto">
             <label for="form-initials">Initials</label>
                <input type="text" id="form-initials" name="initials" />
            </li>
         <li class="ajax-auto">
             <label for="form-company">Company</label>
                <input type="text" id="form-company" name="company" />
            </li>
  </ol>
 </form>

有什么建议吗?

推荐答案

我正在使用自动完成功能，该功能现在已成为jquery ui的一部分. 传递'extraParams'字段不起作用，但是您可以将值附加在请求查询字符串中.

I am using the autocomplete function that is now part of jquery ui. Passing an 'extraParams' field does not work but you can just append the values in the request query string.

$(document).ready(function() {
    src = 'http://domain.com/index.php';

    // Load the cities straight from the server, passing the country as an extra param
    $("#city_id").autocomplete({
        source: function(request, response) {
            $.ajax({
                url: src,
                dataType: "json",
                data: {
                    term : request.term,
                    country_id : $("#country_id").val()
                },
                success: function(data) {
                    response(data);
                }
            });
        },
        min_length: 3,
        delay: 300
    });
});
