我正在使用http://designwithpc.com/Plugins/ddSlick#demo。一个插件,可以使用图像,文本等自定义下拉菜单。 当我从下拉列表中选择一个选择选项但我的浏览器控制台日志显示未定义时,我试图获取文本。我已经尝试将数据放入第7行的变量中,但它仍然给我相同的结果。

$('#myDropdown').ddslick({
    data:ddData,
    width:300,
    selectText: "Select your preferred social network",
    imagePosition:"right",
    onSelected: function(selectedData){
        var selectedData = $('#myDropdown').data('ddslick');
        console.log(selectedData.text);
    }   
});

这是ddData的结构:

var ddData = [{
    text: "Facebook",
    value: 1,
    selected: false,
    description: "Description with Facebook",
    imageSrc: "http://dl.dropbox.com/u/40036711/Images/facebook-icon-32.png"
}, {
    text: "Twitter",
    value: 2,
    selected: false,
    description: "Description with Twitter",
    imageSrc: "http://dl.dropbox.com/u/40036711/Images/twitter-icon-32.png"
}, {
    text: "LinkedIn",
    value: 3,
    selected: true,
    description: "Description with LinkedIn",
    imageSrc: "http://dl.dropbox.com/u/40036711/Images/linkedin-icon-32.png"
}, {
    text: "Foursquare",
    value: 4,
    selected: false,
    description: "Description with Foursquare",
    imageSrc: "http://dl.dropbox.com/u/40036711/Images/foursquare-icon-32.png"
}];

我通过Json Object获取数据。

之前它只返回[object Object]

<div id="myDropdown"></div>
    <script type="text/javascript">
        var jsonurl = 'dropDown.html';
        $.ajax({
            type : 'GET',
            url : jsonurl,
            data : {},
            success : function(myData) {
                $('#myDropdown').ddslick({
                    data : myData,
                    width : 300,
                    selectText : "Select the bill process",
                    imagePosition : "right",
                    onSelected : function(selectedData) {
                        alert(selectedData);
                    }
                });
            },
            error : function() {
            }
        });
    </script>

但是根据我的萤火虫,它显示了我的json响应

[
   {
      "value":1,
      "text":"Process_1",
      "selected":false,
      "imageSrc":"images//priyan.jpg",
      "description":"Process_1"
   },
   {
      "value":2,
      "text":"Process_2",
      "selected":false,
      "imageSrc":"images//priyan.jpg",
      "description":"Process_2"
   },
   {
      "value":3,
      "text":"Process_3",
      "selected":false,
      "imageSrc":"images//priyan.jpg",
      "description":"Process_3"
   }
   ]

然后我就这样改了..

onSelected : function(selectedData) {
                        alert(selectedData);
                    }

onSelected : function(myData) {
                        alert(myData.selectedData.text);
                    }
