javascript右下角弹层及自动隐藏
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:
实现代码如下:
Css样式:
- /*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:
1。自定义右下角弹层函数
- //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:
- 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);
