jQuery UI-自动完成源取决于不同输入中的选定选项 [英] jQuery UI - Autocomplete source dependent from selected option in different input

问题描述

我想使用jquery-ui.min.js中的自动完成脚本.所以在代码中我有:

I would like to use Autocomplete script from jquery-ui.min.js. So in code I have:

<select id="country"><option value="">Choice one</option>
<option value="1">US</option>
<option value="2">UK</option></select>
<input type="text" id="city" >

和脚本:

<script>
$(function() {
  var US= ["City1", "City2", "City3"];
  var UK= ["UK_City1", "UK_City2", "UK_City3"];
  $("#city").autocomplete({  
  source: US  
  });
}); 
</script>

问题是如何根据选择ID ="Country"中用户选择的文本更改源?这也是此脚本: http://jsbin.com/adopo3/35/edit

The question is how to change source dependent on user selected text from Select ID="Country"? Here is also this script: http://jsbin.com/adopo3/35/edit

推荐答案

最简单的方法是使用选项方法更改源.我已经在此处修改了您的示例代码.

Simplest way is to use option method to change the source. I have modified your example code to illustrate it here.

另一种方法是向source选项提供回调函数.请参见此处

Another way would be to supply callback function to the source option. See that here
