在文本框焦点上填充smartautocomplete

Question

我正在使用smartautocomplete。当我搜索任何数据，并且在滚动中完美工作时，它工作正常。 现在我正在尝试当用户点击文本框，然后它会默认显示自动完成框，但我无法打开焦点上的默认自动完成。 我正在使用smartautocomplete.js。 我的代码如下：

$(document).ready(function() { 
    //Input for testing purposes 
    $("#inp").smartautocomplete({ 
     getDataFunc: getData, 
     pageSize: 15, 
     autoFocus: true, 
     focus: function (event, ui) { 
      event.preventDefault(); 
     }, 
     select: function (event, ui) { 
      event.preventDefault(); 
      $('#inp').val(ui.item.label); 
      $('#inp1').val(ui.item.value); 
      //$('#<%=hdnUserID.ClientID%>').val(ui.item.id) 
     }, 
     change: function (event, ui) { 
     } 
    }).focus(function() { 
     //what to write here so i can get default autocomplete value on focus 
    }); 
}); 


//Function the SA plugin called when data is needed. 
//var getData = function (input, pageIndex, pageSize, callback) { 
var getData = function (input, pageIndex, pageSize, callback) { 
    //In this example I use a WebMethod, but you can call anything from a local source to any web service. 
    //url: "../../../Base/BindStateMaster?pageSize=10&pageNum=1&CountryCode=" + ParentddlValue, 
    $.ajax({ 
     type: "POST", 
     url: "../../../Base/BindCountryMasterAuto", 
     data: "{'input':'" + input + "','pageIndex':'" + pageIndex + "','pageSize':'" + pageSize + "'}", 
     contentType: "application/json; charset=utf-8", 
     dataType: "json", 
     dataFilter: function (data) { return data; }, 
     success: function (response) { 

      if (response) { 
       //alert(JSON.stringify(response)); 
       //Data is assumed to be received in a {label: , value: , ...} form, as needed by jqueryUI autocomplete. Of course, if you change the _renderItem function, you are free to modify this as you want 
       response = $.map(response.Data, function (item) { 
        return { 
         label: item.text, 
         value: item.id 
        } 
       }); 
       callback(response); 
      } 
      else callback(); 
     } 

    }); 


}

你可以试试这个

$(function() { 
     $('#id').autocomplete({ 
      source: ["your source array", 

        ], 
      minLength: 0 
     }).focus(function(){    
      $(this).trigger('keydown.autocomplete'); 
// or $(this).autocomplete("search", $(this).val()); 
     }); 
    });
