jquery 自定义alert

前因: 由于在移动设备弹出alert时,特别是在IOS设备中会出现弹出域名的问题,所以自定义弹出框是必要的;
但是遇到一个问题: 自定义 confirm 无法在回调函数中赋值,自义定confirm没有返回Boolean参数,所以在修改或删除时,点击“确定”只有在回调函数中开发

项目开发中是参照如下链接开发:

js代码

(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) {
      debugger;
      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 () {

     //获取当前屏幕的宽度 和高度
     var wondWidth = $(window).width();
     var wondHeight = $(window).height();

     var setWidth = wondWidth * 0.7;
     setWidth = setWidth+"px"

     var setHeight = wondHeight * 0.2;
     setHeight = setHeight+"px"


    $("#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: setWidth, position: 'fixed',
      backgroundColor: 'White', borderRadius: '15px',top:'30%',left:'40%'
    });

    $("#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: '3px 0 10px 0', textAlign: 'center' });
//    $("#mb_btn_ok,#mb_btn_no").css({ width: '80px', height: '25px', color: 'white', border: 'none' });
    $("#mb_btn_ok,#mb_btn_no").css({ width: '80px', height: '25px', color: '#222', 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();
    });
  }
})();

项目总使用

<div class="hesvit_form">
<form>
<input name="id" type="hidden" value="${userRel.id}">
<input name="userId" type="hidden" value="${userRel.userId}">
<input id="remarkName" name="remarkName" value="${userRel.remarkName}" type="text" maxlength="5" placeholder="请输入昵称" />
<input id="accountName" name="accountName"  value="${user.userName}" readonly="readonly" type="text" />
</form>
</div>
<div class="hesvit_btn" onclick="update_data()">保存</div>
<div class="hesvit_btn" onclick="del_data()">删除</div>

<script type="text/javascript">
// 删除关联
function del_data() {

$.MsgBox.Confirm("温馨提示", "您确认要删除吗?", 
function() { 
      var d = {};
      var t = $('form').serializeArray();
      $.each(t, function() {
        d[this.name] = this.value;
      });

      $.ajax({
        type : "POST",
        url :  '${ctx}/wx/userRelation/deleteUserRel',
        data : JSON.stringify(d),
        dataType: 'json',
        contentType: "application/json; charset=utf-8",
        success:function(result) {
            if(result && result.code == '0') {
                var rstdata = result.data;
                window.location.href = "${ctx}/wx/userRelation/addButtomUserRelation.wxhtml";
            }else {
                $.MsgBox.Alert("消息",result.message);
            }
        },
        error : function(XMLHttpRequest, textStatus, errorThrown) {
            $.MsgBox.Alert("错误消息","删除失败>:"+textStatus);
        }
    });

});

}
</script>

jquery 默认confirm

 var choice = confirm("您确认要删除吗?", function() {
    }, null);
    if(choice){
    }
