javascript右下角弹层及自动隐藏(自己编写)

  在编写项目中总会需要有个右下角弹层提示公告的需求,怎么用更简单方面,更简洁代码,实现更好用户体验这个就是我们的所要做的内容。市场这块弹层很多,但功能不尽如人意。下面分享早些时候自己编写,以及现在还在应用的自动弹层。

  弹层示例图:

javascript右下角弹层及自动隐藏(自己编写)

  实现代码如下:

  Css样式:

  

复制代码 代码如下:

  /*通知提示层*/

  .msg_info{ font-size: 12px; text-align: left; z-index: 100; position: absolute; display: none; bottom: 0; right: 0; overflow: hidden;}

  .msg_info h3{float: left;margin: 0px;height: 0px;width: 100%; color: #fff; height: 30px;}

  .msg_info h3 span, .msg_info h3 b, .msg_info h3 em, .msg_info small span, .msg_info small b, .msg_info small em{ background-image: url(/img/msg_bg.png);}

  .msg_info h3 b, .msg_info h3 em, .msg_info small b, .msg_info small em{ float: left;font-size: 1px; width: 6px; height: 30px;}

  .msg_info h3 b{ background-position: 0px 0px;}

  .msg_info h3 em{ background-position: 0px -32px;}

  .msg_info h3 span{background-position: 0px -64px;float: left;line-height: 30px;}

  .msg_info h3 span font{float: left;text-align: left;overflow: hidden; margin-left: 12px;}

  .msg_info h3 span i{ float: right; margin-right: 10px; cursor: pointer;font-style:normal;}

  .message_content{ float: left;color: #515F62;overflow: hidden;border-left: solid 1px #C2C2C2; background-color: #F1F2F7; margin-top: -1px; min-height: 145px; height: auto !important; height: 145px;}

  .message_content div{ float: left; margin: 0px; padding: 10px 14px;height: 100%;position:relative;}

  .message_content div p.message_txt{ float: left;width: 100%;height: 80%;margin: 0px; padding: 0px;min-height:60px;}

  .message_content div i{float: left; font-style: normal; margin-top: 2px;text-align:right;position:fixed;bottom:2px;right:4px;}

  .message_content b.bright{ float: right; width: 1px; font-size: 1px;background-color: #C2C2C2; border-right: solid 1px #828282;height: 100%;}

  .msg_info small{float: left; width: 100%; height: 5px; font-size: 5px;}

  .msg_info small span{ background-position: 0px -101px;height: 5px; float: left;}

  .msg_info small b{height: 5px; background-position: 0px -96px;}

  .msg_info small em{ height: 5px; background-position: 0px -106px; float: right;}

  Js部分:

  自定义右下角弹层函数

  

复制代码 代码如下:

  //右下角弹层

  function Messager() {

  this.layer = { 'width': 200, 'height': 100 };

  this.title = '信息提示';

  this.time = 4000;

  this.anims = { 'type': 'slide', 'speed': 600 };

  this.timer1 = null;

  this.isTiming = false;

  this.obj_id = "msg_" + $(document.body).find('msg_info').length;

  var _obj, _title, _anims, _time;

  _timer2 = null;

  //初始化

  this.inits = function (title, text) {

  _anims = this.anims;

  _title = title;

  var _html = '<div class="msg_info ' + this.obj_id + '">';

  _html += ' <h3>';

  _html += ' <b></b>';

  _html += ' <span class="msg_bg_middle">';

  _html += ' <font>' + title + '</font>';

  _html += ' <i class="message_close">×</i>';

  _html += ' </span>';

  _html += ' <em></em>';

  _html += ' </h3>';

  _html += ' <div class="message_content">';

  _html += ' <div class="msg_txt">' + text + '</div>';

  _html += ' <b class="bright"></b>';

  _html += ' </div>';

  _html += ' <small><b></b><span class="msg_bg_middle"></span><em></em></small>';

  _html += '</div>';

  $(document.body).prepend(_html);

  _obj = $("." + this.obj_id);

  if ($.browser.msie) {

  _obj.css('bottom', -5);

  }

  _obj.css('width', this.layer.width);

  _obj.find('.msg_bg_middle').css('width', this.layer.width - 12);

  _obj.find('.message_content').css('width', this.layer.width - 2);

  _obj.find('.msg_txt').css('width', this.layer.width - 34);

  _obj.find(".message_close").click(function () {

  setTimeout(function () { closeMsg(); }, 1);

  });

  _obj.hover(function () {

  clearTimeout(timer1);

  clearInterval(_timer2);

  _timer2 = timer1 = null;

  }, function () {

  timer1 = setTimeout(function () { closeMsg(); }, _time * 1000);

  timing(_time * 1000);

  });

  };

  //显示

  this.show = function (title, text, time) {

  if (title == 0 || !title) title = this.title;

  this.inits(title, text);

  if (time >= 0) this.time = time;

  switch (this.anims.type) {

  case 'slide': _obj.slideDown(this.anims.speed); break;

  case 'fade': _obj.fadeIn(this.anims.speed); break;

  case 'show': _obj.show(this.anims.speed); break;

  default: _obj.slideDown(this.anims.speed); break;

  }

  this.rmmessage(this.time);

  };

  //设置宽高

  this.lays = function (width, height) {

  if (width != 0 && width) this.layer.width = width;

  if (height != 0 && height) this.layer.height = height;

  };

  //呈现属性

  this.anim = function (type, speed) {

  if (type != 0 && type) this.anims.type = type;

  if (speed != 0 && speed) {

  switch (speed) {

  case 'slow': ; break;

  case 'fast': this.anims.speed = 200; break;

  case 'normal': this.anims.speed = 400; break;

  default: this.anims.speed = speed; break;

  }

  }

  };

  //移除层时间

  this.rmmessage = function (time) {

  if (time > 0) {

  timer1 = setTimeout(function () { closeMsg(); }, time);

  if (this.isTiming) {

  timing(time);

  }

  }

  };

  //计时

  timing = function (time) {

  _time = time / 1000;

  _timer2 = setInterval(function () {

  _obj.find('.msg_bg_middle').find('font').html(_title + ' [' + (--_time) + '秒后自动关闭]');

  }, 1000);

  }

  //关闭层

  closeMsg = function () {

  switch (_anims.type) {

  case 'slide': _obj.slideUp(_anims.speed); break;

  case 'fade': _obj.fadeOut(_anims.speed); break;

  case 'show': _obj.hide(_anims.speed); break;

  default: _obj.slideUp(_anims.speed); break;

  }

  setTimeout(function () { _obj.remove(); }, _anims.speed);

  }

  }

  示例函数:

  

复制代码 代码如下:

  var msg = '<p class="message_txt">当前有' + json.total + '个待审核用户等待您审核。</p><i>' + json.stadate + '</i>';

  var msgDiv = new Messager();

  msgDiv.isTiming = true;

  msgDiv.lays(300, 180);

  msgDiv.show("用户审核提醒", msg, 10000);
