js网页右下角提示框实例

本文实例讲述了js网页右下角提示框的实现方法，分享给大家供大家参考。具体方法如下：
html代码部分如下：


代码如下:


<style type="text/css">
.messageTip{border-right: #455690 1px solid; border-top: #a6b4cf 1px solid; border-left: #a6b4cf 1px solid; border-bottom: #455690 1px solid; z-index:99999; left: 0px; top: 0px; visibility:hidden; width: 230px; position: absolute; background:#cfdef4; text-align:left}
.messageTip .close{position:absolute; right:0px; font-weight:bold; padding:4px 4px 0 0;}
.messageTip .close a{color:red;font-size:12px; text-decoration:none;}
.messageTip .content{border-top: #ffffff 1px solid; border-left: #ffffff 1px solid}
.messageTip .content .title{color: #1f336b; padding-top: 4px;padding-left: 4px; height:22px;}
.messageTip .content .msg{border-right: #b9c9ef 1px solid;border-left: #728eb8 1px solid; border-top: #728eb8 1px solid; padding:10px; margin:1px}
</style>

<script type="text/javascript" src="/js/base.js"></script> <div id="eMeng" class="messageTip">     <div class="close"><a href="javascript:msgTip.close();" title="关闭">×</a></div>     <div class="content">         <div class="title">系统提示：</div>         <div class="msg">         内容         </div>     </div> </div>


js代码部分如下：


代码如下:


function messageTip(pJso) {
    _.init(this, pJso, {
        name: 'msg'//提示框标签ID
    });
    this.eMsg = document.getElementById(this.name);
}

messageTip.prototype = {     //提示框始终在最右下角     rePosition: function(_this) {         var divHeight = parseInt(_this.eMsg.offsetHeight, 10);         var divWidth = parseInt(_this.eMsg.offsetWidth, 10);         var docWidth = document.body.clientWidth;         var docHeight = document.body.clientHeight;         _this.eMsg.style.top = docHeight - divHeight + parseInt(document.body.scrollTop, 10);         _this.eMsg.style.left = docWidth - divWidth + parseInt(document.body.scrollLeft, 10);     },
    //提示框慢慢往上升     moveDiv: function(_this) {         /*         这里可以设置自动几秒后关闭         ...         */         try {             if (parseInt(_this.eMsg.style.top, 10) <= (_this.docHeight - _this.divHeight + parseInt(document.body.scrollTop, 10))) {                 window.clearInterval(_this.objTimer);                 _this.objTimer = window.setInterval(function() { _this.rePosition(_this); }, 1);             }             _this.divTop = parseInt(_this.eMsg.style.top, 10);             _this.eMsg.style.top = _this.divTop - 1;         }         catch (e) {         }     },         //关闭提示框     close: function() {         this.eMsg.style.visibility = 'hidden';         if (this.objTimer) window.clearInterval(this.objTimer);     },
    //显示提示框     show: function() {         var divTop = parseInt(this.eMsg.style.top, 10);         this.divTop = divTop;         var divLeft = parseInt(this.eMsg.style.left, 10);
        var divHeight = parseInt(this.eMsg.offsetHeight, 10);         this.divHeight = divHeight;
        var divWidth = parseInt(this.eMsg.offsetWidth, 10);         var docWidth = document.body.clientWidth;         var docHeight = document.body.clientHeight;         this.docHeight = docHeight;
        this.eMsg.style.top = parseInt(document.body.scrollTop, 10) + docHeight + 10;         this.eMsg.style.left = parseInt(document.body.scrollLeft, 10) + docWidth - divWidth;         this.eMsg.style.visibility = "visible";
        var _this = this;         this.objTimer = window.setInterval(function() { _this.moveDiv(_this); }, 10);     } }
var msgTip = new messageTip({ name: 'eMeng' }); window.onload = function() { msgTip.show(); }; window.onresize = function() { msgTip.rePosition(msgTip); };
