jquery封装的对话框简单实现

var _alert_iconCss = "tipmsg_icoInfo";
var _confirm_iconCss = "tipmsg_icoConfirm";
var _error_iconCss = "tipmsg_icoError";
var _warning_iconCss = "tipmsg_icoWarning";
function dialogInit(type, msg) {
var iconCss = "";
switch (type) {
case "confirm" : iconCss = _confirm_iconCss; break;
case "error" : iconCss = _error_iconCss; break;
case "warning" : iconCss = _warning_iconCss; break;
default : iconCss = _alert_iconCss; break;
}

var htmlStr = "<div id='" + type + "Div' style='display: none;'><p><span class='" + iconCss + "' style='float:left; margin:0 7px 50px 0;width:35px;height:35px;'></span>" + msg + "</p></div>";
return htmlStr;
}
function Alert(msg, okCallback) {
var title = "提示";
var type = "alert";
var html = dialogInit(type, msg);
var div = $("body").find("#"+type+"Div");
div.remove();
$('body').append($(html));

var buttons = {"确定" : function () {
if(okCallback) okCallback();
$(this).dialog("close");
}
};

$("#"+type+"Div").dialog({
modal : true,
title : title,
buttons : buttons
});
}
function Confirm(msg, okCallback, cancelCallback) {
var title = "确认";
var type = "confirm";
var html = dialogInit(type, msg);
var div = $("body").find("#"+type+"Div");
div.remove();
$('body').append($(html));

var buttons = {"确定" : function () {
