Question

我正在尝试创建一个AJAX控件，我无法在控件中看到属性get_和set_方法。

这是我在.js文件中的代码：

Type.registerNamespace('MyCompany.ControlLibrary');

MyCompany.ControlLibrary.WebNotify = function(element)
{
    // Module level variables
    this._message = '';

    //Calling the base class constructor
    MyCompany.ControlLibrary.WebNotify.initializeBase(this, [element]);
}


MyCompany.ControlLibrary.WebNotify.prototype =
{
    //Getter for Message Property
    get_message : function()
    {
        return this._message;
    },

    //Setter for Message Property
    set_message : function(value)
    {debugger;
        var e = Function._validateParams(arguments, [{name: 'value', type: String}]);
        if (e) throw e;

        if (this._message != value)
        {
            // Only sets the value if it differs from the current
            this._message = value;
            //Raise the propertyChanged event
            this.raisePropertyChanged('message'); //This is a base class method which resides in Sys.Component
        }
    },

    initialize : function()
    {
        //Call the base class method
        MyCompany.ControlLibrary.WebNotify.callBaseMethod(this, 'initialize');
    },

    dispose : function()
    {
        //Call the base class method
        MyCompany.ControlLibrary.WebNotify.callBaseMethod(this, 'dispose');
    }
}





MyCompany.ControlLibrary.WebNotify.registerClass('MyCompany.ControlLibrary.WebNotify', Sys.UI.Control);

if (typeof(Sys) != 'undefined')
{
    Sys.Application.notifyScriptLoaded();
}

这是我在.cs文件后面的代码中的属性：

[DescriptionAttribute("The message that is displayed in the notifier.")]
public string Message
{
    get { return _message; }
    set { _message = value; }
}
private string _message = "No Message Specified";

miss miss [ExtenderControlProperty]属性

Answer 2

我不需要任何AJAX Control Kit的东西。我只需要使用$ find而不是$ get。现在我使用$发现一切都很完美。

真是头疼。

为什么我的属性得到并设置为不在AJAX控件中公开？
