Alert 重写

做多语言的时候发现原生Alert()在测试时不能满足需求,在网上找了一篇文章,记一下

      (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 += '<div id="mb_box"></div><div id="mb_con"><span id="mb_tit">' + title + '</span>';
              _html += '<a id="mb_ico">x</a><div id="mb_msg">' + msg + '</div><div id="mb_btnbox">';

              if (type == "alert") {
                  _html += '<input id="mb_btn_ok" type="button" value="确定" />';
              }
              if (type == "confirm") {
                  _html += '<input id="mb_btn_ok" type="button" value="确定" />';
                  _html += '<input id="mb_btn_no" type="button" value="取消" />';
              }
              _html += '</div></div>';

              //必须先将_html添加到body，再设置Css样式
              $("body").append(_html); GenerateCss();
          }

          //生成Css
          var GenerateCss = function () {

              $("#mb_box").css({
                  width: '100%', height: '100%', zIndex: '99999', position: 'fixed',
                  filter: 'Alpha(opacity=60)', backgroundColor: 'black', top: '0', left: '0', opacity: '0.6'
              });

              $("#mb_con").css({
                  zIndex: '999999', width: '400px', position: 'fixed',
                  backgroundColor: 'White', borderRadius: '15px'
              });

              $("#mb_tit").css({
                  display: 'block', fontSize: '14px', color: '#444', padding: '10px 15px',
                  backgroundColor: '#DDD', borderRadius: '15px 15px 0 0',
                  borderBottom: '3px solid #009BFE', fontWeight: 'bold'
              });

              $("#mb_msg").css({
                  padding: '20px', lineHeight: '20px',
                  borderBottom: '1px dashed #DDD', fontSize: '13px'
              });

              $("#mb_ico").css({
                  display: 'block', position: 'absolute', right: '10px', top: '9px',
                  border: '1px solid Gray', width: '18px', height: '18px', textAlign: 'center',
                  lineHeight: '16px', cursor: 'pointer', borderRadius: '12px', fontFamily: '微软雅黑'
              });

              $("#mb_btnbox").css({ margin: '15px 0 10px 0', textAlign: 'center' });
              $("#mb_btn_ok,#mb_btn_no").css({ width: '85px', height: '30px', color: 'white', border: 'none' });
              $("#mb_btn_ok").css({ backgroundColor: '#168bbb' });
              $("#mb_btn_no").css({ backgroundColor: 'gray', marginLeft: '20px' });


              //右上角关闭按钮hover样式
              $("#mb_ico").hover(function () {
                  $(this).css({ backgroundColor: 'Red', color: 'White' });
              }, function () {
                  $(this).css({ backgroundColor: '#DDD', color: 'black' });
              });

              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" });
          }


          //确定按钮事件
          var btnOk = function (callback) {
              $("#mb_btn_ok").click(function () {
                  $("#mb_box,#mb_con").remove();
                  if (typeof (callback) == 'function') {
                      callback();
                  }
              });
          }

          //取消按钮事件
          var btnNo = function () {
              $("#mb_btn_no,#mb_ico").click(function () {
                  $("#mb_box,#mb_con").remove();
              });
          }
      })();

肯定的,还需要引入jquery文件
