jquery之弹框

用jquery实现弹框脚本的封装，

(function() {
    $.MsgBox = {
        Alert: function(title, msg) {
            GenerateHtml("alert", title, msg);
            btnOk(); //alert只是弹出消息，因此没必要用到回调函数callback
            btnNo();
        },
        Confirm: function(title, msg, callback) {
            GenerateHtml("confirm", title, msg);
            btnOk(callback);
            btnNo();
        }
    }
    //生成Html
    var GenerateHtml = function(type, title, msg) {
        var _html = "";
        _html += '
' + title + '';
        _html += 'x
' + msg + '
';
        if (type == "alert") {
            _html += '';
        }
        if (type == "confirm") {
            _html += '';
            _html += '';
        }
        _html += '
';
        //必须先将_html添加到body，再设置Css样式
        $("body").append(_html);
        //生成Css
        GenerateCss();
    }

    //生成Css
    var GenerateCss = function() {
        $("#mb_box").css({
            width: '100%',
            height: '100%',
            zIndex: '99999',
            position: 'fixed',
            filter: 'Alpha(opacity=60)',
            backgroundColor: 'black',

        });
        $("#mb_msg").css({

        });
        $("#mb_btnbox").css({
            margin: '15px 0 10px 0',
            textAlign: 'center'

        var _widht = document.documentElement.clientWidth; //屏幕宽
        var _height = document.documentElement.clientHeight; //屏幕高
        var boxWidth = $("#mb_con").width();
        var boxHeight = $("#mb_con").height();
        //让提示框居中
        $("#mb_con").css({
            top: (_height - boxHeight) / 2 + "px",
            left: (_widht - boxWidth) / 2 + "px"
