电力项目十一--js添加浮动框

1.添加浮动窗口样式

<!-- 浮动窗口样式css begin -->
<style type="text/css">
    #msg_win{border:1px solid #A67901;background:#EAEAEA;240px;position:absolute;right:0;font-size:12px;font-family:Arial;margin:0px;display:none;overflow:hidden;z-index:99;}
    #msg_win .icos{position:absolute;top:2px;*top:0px;right:2px;z-index:9;}
    .icos a{float:left;color:#833B02;margin:1px;text-align:center;font-weight:bold;14px;height:22px;line-height:22px;padding:1px;text-decoration:none;font-family:webdings;}
    .icos a:hover{color:#fff;}
    #msg_title{background:#BBDEF6;border-bottom:1px solid #A67901;border-top:1px solid #FFF;border-left:1px solid #FFF;color:#000;height:25px;line-height:25px;text-indent:5px;}
    #msg_content{margin:5px;margin-right:0;230px;height:126px;overflow:hidden;}
</style>
<!-- 浮动窗口样式css end -->

2.添加浮动窗口js

<!-- 浮动窗口js，必须要放置到最后  begin-->
<script language="javascript">
var Message={
    set: function() {//最小化与恢复状态切换
        var set=this.minbtn.status == 1?[0,1,'block',this.char[0],'最小化']:[1,0,'none',this.char[1],'展开'];
        this.minbtn.status=set[0];
        this.win.style.borderBottomWidth=set[1];
        this.content.style.display =set[2];
        this.minbtn.innerHTML =set[3]
        this.minbtn.title = set[4];
        this.win.style.top = this.getY().top;
    },
    close: function() {//关闭
        this.win.style.display = 'none';
        window.onscroll = null;
    },
    setOpacity: function(x) {//设置透明度
        var v = x >= 100 ? '': 'Alpha(opacity=' + x + ')';
        this.win.style.visibility = x<=0?'hidden':'visible';//IE有绝对或相对定位内容不随父透明度变化的bug
        this.win.style.filter = v;
        this.win.style.opacity = x / 100;
    },
    show: function() {//渐显
        clearInterval(this.timer2);
        var me = this,fx = this.fx(0, 100, 0.1),t = 0;
        this.timer2 = setInterval(function() {
            t = fx();
            me.setOpacity(t[0]);
            if (t[1] == 0) {clearInterval(me.timer2) }
        },10);
    },
    fx: function(a, b, c) {//缓冲计算
        var cMath = Math[(a - b) > 0 ? "floor": "ceil"],c = c || 0.1;
        return function() {return [a += cMath((b - a) * c), a - b]}
    },
    getY: function() {//计算移动坐标
        var d = document,b = document.body, e = document.documentElement;
        var s = Math.max(b.scrollTop, e.scrollTop);
        var h = /BackCompat/i.test(document.compatMode)?b.clientHeight:e.clientHeight;
        var h2 = this.win.offsetHeight;
        return {foot: s + h + h2 + 2+'px',top: s + h - h2 - 2+'px'}
    },
    moveTo: function(y) {//移动动画
        clearInterval(this.timer);
        var me = this,a = parseInt(this.win.style.top)||0;
        var fx = this.fx(a, parseInt(y));
        var t = 0 ;
        this.timer = setInterval(function() {
            t = fx();
            me.win.style.top = t[0]+'px';
            if (t[1] == 0) {
                clearInterval(me.timer);
                me.bind();
            }
        },10);
    },
    bind:function (){//绑定窗口滚动条与大小变化事件
        var me=this,st,rt;
        window.onscroll = function() {
            clearTimeout(st);
            clearTimeout(me.timer2);
            me.setOpacity(0);
            st = setTimeout(function() {
            me.win.style.top = me.getY().top;
            me.show();
            },600);
        };
        window.onresize = function (){
            clearTimeout(rt);
            rt = setTimeout(function() {me.win.style.top = me.getY().top},100);
        }
    },
    init: function() {//创建HTML
        function $(id) {return document.getElementById(id)};
        this.win=$('msg_win');
        var set={minbtn: 'msg_min',closebtn: 'msg_close',title: 'msg_title',content: 'msg_content'};
        for (var Id in set) {this[Id] = $(set[Id])};
        var me = this;
        this.minbtn.onclick = function() {me.set();this.blur()};
        this.closebtn.onclick = function() {me.close()};
        this.char=navigator.userAgent.toLowerCase().indexOf('firefox')+1?['_','::','×']:['0','2','r'];//FF不支持webdings字体
        this.minbtn.innerHTML=this.char[0];
        this.closebtn.innerHTML=this.char[2];
        setTimeout(function() {//初始化最先位置
            me.win.style.display = 'block';
            me.win.style.top = me.getY().foot;
            me.moveTo(me.getY().top);
        },0);
        return this;
    }
};
Message.init();
</script>
<!-- 浮动窗口js end-->

 3.html代码，放在body之后

    <!-- 浮动窗口html代码 begin -->
    <hr>
    <div id="msg_win" style="display:block;top:490px;visibility:visible;opacity:1;">
        <div class="icos">
            <a id="msg_min" title="最小化" href="javascript:void 0">_</a><a id="msg_close" title="关闭" href="javascript:void 0">×
            </a>
        </div>
        <div id="msg_title">
            设备运行情况-->
        </div>
        <div id="msg_content" style="overflow:auto;height:150px;100%;white-space:nowrap">
            <s:property value="devRun" escape="false"/>
            
        </div>
    </div>
    <!-- 浮动窗口html代码 end -->

 4.在ElcMenuAction.java中的方法loading中添加：

    /**  
    * @Name: loading
    * @Description: 功能页面的显示
    * @Version: V1.00 （版本号）
    * @Return: String：跳转到menu/loading.jsp
    */
    public String loading(){
        //查询设备运行情况，放置到浮动框中
        //1：查询数据库运行监控表的数据，返回惟一ElecCommonMsg
        ElecCommonMsg commonMsg = elecCommonMsgService.findCommonMsg();
        //2：将ElecCommonMsg对象压入栈顶，支持表单回显
        ValueUtils.putValueStack(commonMsg);
        return "loading";
    }

5.页面：

<%@ taglib uri="/struts-tags" prefix="s" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
