如何从AUI自动完成列表中获取所选项目

How to get selected item from AUI autocomplete list

本文关键字：列表 获取 项目 选项 AUI      更新时间：2023-09-26

我想在数据库中向自动完成的aui输入字段显示地址。一切似乎都很好。但是我无法检索记录的地址号码。如何使用自动完成列表的on change事件，或者我如何访问所选项目的json对象

  @Override
        public void serveResource( ResourceRequest resourceRequest, ResourceResponse resourceResponse ) throws IOException,
                PortletException
        {

            String cmd = ParamUtil.getString(resourceRequest, "get_address");
            String myInputNode = ParamUtil.getString(resourceRequest, "addressAutocomplete");
            System.out.println("addressAutocomplete"+myInputNode);
            if (cmd.equals("get_address")) {
             getUsers(resourceRequest, resourceResponse,myInputNode);
            }
            }

    private void getUsers(ResourceRequest resourceRequest, ResourceResponse resourceResponse, String myInputNode) throws IOException, PortletException {
                JSONArray usersJSONArray = JSONFactoryUtil.createJSONArray();
                ThemeDisplay themeDisplay =    (ThemeDisplay)resourceRequest.getAttribute(WebKeys.THEME_DISPLAY);
                JSONObject userJSON=null;
                try {
                List<AddressMaster> userList=AddressMasterLocalServiceUtil.getAllAddressBySearchKey( myInputNode );
                                           for(AddressMaster addressMaster:userList){
                userJSON=JSONFactoryUtil.createJSONObject();
                userJSON.put("addressNumber",addressMaster.getAdrNummer());
                userJSON.put( "address",  addressMaster.getAddress())
         );
                       usersJSONArray.put(userJSON);
                }
                } catch (Exception e) {
                }
                PrintWriter out=resourceResponse.getWriter();
                out.println(usersJSONArray.toString());
                System.out.println("usersJSONArray"+usersJSONArray.toString());

            }

Jsp文件

<portlet:resourceURL var="getAddress">
   <portlet:param name="get_address" value="get_address" />
 </portlet:resourceURL>

 <aui:input id="addressAutocomplete"  name="addressAutocomplete" label="group_choose_address"   style="width:700px"/>
<aui:script>
AUI().use('autocomplete-list','aui-base','aui-io-request','autocomplete-filters','autocomplete-highlighters',function (A) {
A.io.request('<%=getAddress%>',{
dataType: 'json',
method: 'GET',
on: {
success: function() {
//continents=this.get('responseData');
//alert(continents[0].name);
new A.AutoCompleteList(
{
allowBrowserAutocomplete: 'true',
activateFirstItem: 'true',
inputNode: '#<portlet:namespace/>addressAutocomplete',
resultTextLocator: 'address',
resultHighlighter:['phraseMatch'],
resultFilters:['phraseMatch'],
render: 'true',
source:this.get('responseData'),
});
}}
});                  
});
</aui:script>

要想准确地了解即将发生的事情有点棘手，但我认为你可以这样做：

var address_ac = new A.AutoCompleteList({... as you have it...});
address_ac.on('select', function (e) {
    var selected_node = e.itemNode,
        selected_data = e.result;
});
