根据Bootstrap的Modal开发的提示框

(function ($) {
$(function () {
var Modal = function () {

"<h5 class=\"modal-title\"><i class=\"fa fa-exclamation-circle\"></i> [Title]</h5>" +
"</div>" +
"<div class=\"modal-body small\">" +
"<p>[Message]</p>" +
"</div>" +
"<div class=\"modal-footer\">" +
" <button type=\"button\" class=\"btn btn-primary ok\" data-dismiss=\"modal\">[BtnOk]</button>" +
" <button type=\"button\" class=\"btn btn-default cancel\" data-dismiss=\"modal\">[BtnCancel]</button>" +
"  </div>" +
"  </div> " +
