mui选择器怎样接受ajax传过来的数据?

    var data = certificate.hotelName();  
    alert(data);  
    (function($) {  
        var userPicker = new $.PopPicker();//在这接受ajax 数据  
        userPicker.setData();  
        var showUserPickerButton = document.getElementById('hotelTab');  
        var userResult = document.getElementById('hotelNames');  
        showUserPickerButton.addEventListener('tap', function(event) {  
            userPicker.show(function(items) {  
                var data = JSON.stringify(items[0]);  
                var dataObj = eval("(" + data + ")");  
                userResult.value = dataObj.text;  
                //返回 false 可以阻止选择框的关闭  
                //return false;  
            });  
        }, false);  
    })(mui);
