写一个简单的基于jquery的对话框

css:

#dialog
        {
            border:solid 1px #CCC;
            width:300px;
            height:150px;
            background-color:#e5e5e5;
            position:fixed;
        }
        .title
        {
            width:100%;
            height:30px;
            background:#dadada;
            color:#a68687;
            font-size:22px;
        }
        #TContent
        {
            line-height:35px;
            margin-left:5px;
        }
        .content
        {
            height:80px;
            width:100%;
            text-align:center;
        }
        #CContent
        {
            line-height:25px;
            font-size:16px;
        }
        .buttons
        {
            width:100%;
            text-align:center;
        }
        #TTButton1,#TTButton2
        {
            cursor:pointer;
            width:60px;
            height:30px;
            margin:0 5px 0 5px;
            border:0 none;
            color:White;
        }

js:

$.extend({
            confirms: function (options) {
                var defaults = {
                    title: "Delete Confirmation",
                    message: "You are about to delete this item. <br />It cannot be restored at a later time! Continue?",
                    buttons: {
                        "Yes": { 'class': 'blue', 'action': function () { alert("你点击了Yes"); } },
                        "No": { 'class': 'gray', 'action': function () { $("#dialog").remove(); } }
                    }
                };
                var opts = $.extend(defaults, options);

                $("<div id='dialog'><div class='title'><span id='TContent'>" + defaults.title +
                 "</span></div><div class='content'><span id=CContent>" + defaults.message +
                 "</span></div><div class='buttons'><input id='TTButton1' style='background-color:" +
                 defaults.buttons['Yes']['class'] + "' type='button' value='Yes' /><input id='TTButton2' type='button' style='background-color:" +
                 defaults.buttons['No']['class'] + "' value='No' /></div></div>").appendTo("body");

                $("#TTButton1").bind("click", defaults.buttons['Yes']['action']);
                $("#TTButton2").bind("click", defaults.buttons['No']['action']);

                $("#dialog").css("top", ($(document).height() - $("#dialog").height()) / 2 - 100);
                $("#dialog").css("left", ($(document).width() - $("#dialog").width()) / 2);
            }
        });
        function test() {
            $.confirms({
                title: "测试",
                message: "这是一个测试对话框！",
                buttons:{
                            "Yes":{'class':'red','action':function () { alert("你对cx说：真2！"); }},
                            "No": { 'class': 'gray', 'action': function () { $("#dialog").remove(); } }
                        }
            });
        }

html测试代码：

<input id="Button1" type="button" value="button" onclick="test();" />

简简单单，完成咯

遇到的问题：$("123").appendTo("p");无效 $("<b>123</b>").appendTo("p");就可以 不知什么原因
