一.前言

最近在做一个项目，自己感觉系统自带的alert()方法的弹出框实在是不堪入目，所以在网上找了一些资料，然后自己加工了一下，做出了自己的一个js弹出框，在这里贡献出来，希望对你有帮助.

二.开始

在这里我们来一个获取验证码的页面来说明，也是在我项目用用到的一个页面。我们首先创建一个HTML的静态页面。其中代码如下:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><title>自定义提示</title><script src="jquery-1.8.3.js" type="text/javascript"></script><script src="sAlter.js" type="text/Javascript"></script><link href="GetRelationByPhone.CSS" rel="stylesheet" type="text/css" /></head><body> <div>      <form id="form1" action="#" method="post">        <div>            <section class="infos">            <label class="fLeft">手机号</label>            <input type="hidden" value="oLlIXuNocl66hPYHHt8vwAOLhWTA" name="openid" />            <span class="commeInput"><input type="text" class="no-border" name="phone" id="phone" value="" placeholder="请输入您的手机号"/>            </span>            <em id="mob" class="yg-input-close rt12"></em></section>            <section class="infos no-boder">            <label class="fLeft">验证码</label>            <span class="commeInput"><input type="text" class="no-border2" name="code" id="code" value="" placeholder="请输入验证码"  />            <input type="button" id="btn"  class="btn_mfyzm" value="获取验证码"  onclick="getverify()"    />            </span>            <em id="mob2" class="yg-input-close lt50"></em></section>            <div><button type="button" class="btn-pay" onclick="go()"  title="确定">确&nbsp &nbsp 定</button></div>        </div>      </form></div></body></html>

sAlter.js就是我们封装过后的js。我们先看看使用的效果：

来看看我们的页面js代码如下：

<script type="text/javascript">    function timer(time) {        var btn = $("#btn");        btn.attr("disabled", true);  //按钮禁止点击        btn.val(time <= 0 ? "发送验证码" : ("" + (time) + "秒"));        var hander = setInterval(function () {            if (time <= 0) {                clearInterval(hander); //清除倒计时                btn.val("发送验证码");                btn.attr("disabled", false);                return false;            } else {                btn.val("" + (time--) + "秒");            }        }, 1000);    }    //绑定手机号码    function go() {        var phone = $("#phone").val();        if (phone == "" || phone == "请输入11位手机号码" || phone == null) {            NewAlertBox("warning", "请输入11位手机号码", 3000);            return;        }        var myreg = /^(((13[0-9]{1})|(15[0-9]{1})|(18[0-9]{1}))+/d{8})$/;        if (!myreg.test($("#phone").val())) {            NewAlertBox("warning", "请输入有效的手机号码！", 3000);            $("#phone").val("");            return;        }        var code = $("#code").val();        if (code == "" || code == "请输入验证码" || code == null) {            NewAlertBox("warning", "请输入验证码！", 3000);            return;        }//        $.Ajax({//            url: "RelationCarNoByPhone.ashx?type=2&code=" + code + "&phone=" + phone,//            type: "POST",//            dataType: "json",//            cache: false,//            success: function (data) {//                if (data.code == "0") {                    NewAlertBox("warning", "绑定成功！", 3000, function () { WeixinJSBridge.call('closeWindow'); });//                }//                else {//                    NewAlertBox("warning", data.msg, 3000, function () { WeixinJSBridge.call('closeWindow'); });//                }//            }//        });    }    //获取验证码    function getverify() {        var phone = $("#phone").val();        if (phone == "" || phone == "请输入11位手机号码" || phone == null) {            NewAlertBox("warning", "请输入11位手机号码", 3000);            return;        }        var myreg = /^(((13[0-9]{1})|(15[0-9]{1})|(18[0-9]{1}))+/d{8})$/;        if (!myreg.test($("#phone").val())) {            NewAlertBox("warning", "请输入有效的手机号码！", 3000);            $("#phone").val("");            return;        }        timer(120);//        $.ajax({//            url: "RelationCarNoByPhone.ashx?type=1&phone=" + phone,//            type: "POST",//            dataType: "json",//            cache: false,//            success: function (data) {//                if (data.code == "0") {                    NewAlertBox("ok", "验证码获取成功！", 3000);//                } else {//                    NewAlertBox("warning", data.msg, 3000);//                }//            }//        });    }</script>

从上面的代码中我们看到这个封装的js使用起来非常简单 NewAlertBox("warning", "请输入11位手机号码", 3000);传入一些参数就可以达到我们要的效果。

三.核心代码

我们要的效果也达到了，sAlter.js这个里面究竟是个什么样子的，其中代码如下:

/* js弹窗代码:用户体验极佳的Alert提示效果 e-mail:616931@QQ.com source:枫伶亿博客*/var t;var argl,funcf;//获取指定ID的元素function $xp(id) { return document.getElementById(id);}//通用事件获取接口function getEvent(){ if(CheckBrowser()=='IE')  return window.event; func=getEvent.caller; while(func!=null) {  var arg0 = func.arguments[0];  if(arg0)  {   if((arg0.constructor==Event || arg0.constructor ==MouseEvent)   || (typeof(arg0)=="object" && arg0.PReventDefault && arg0.stopPropagation))   {    return arg0;   }  }  func=func.caller; } return null;}//alertfunction NewAlertBox(itype,msg,time){//time为消失时间 var msgbg,msgcolor,bordercolor,content,posLeft,posTop,imgName; argl=arguments.length; if(argl>3) {funcf = arguments[3];}//外部方法 //弹出窗口设置 msgbg = "#FFF";   //内容背景 msgcolor = "#f66f15";  //内容颜色 bordercolor = "#d8bfd8";  //边框颜色 //遮罩背景设置 //判断图片类型 if(itype.toUpperCase()=='OK') //提示通过     imgName = '../Img/ts_ok.png'; else if(itype.toUpperCase()=='ERROR') //提示报错     imgName = '../Img/ts_error.png'; else //提示警告或者其他     imgName = '../Img/ts_warning.png';  content = "<img src='" + imgName + "' alt='img ' style='width:78px;height:78px;'/><br/>" + msg; var sWidth,sHeight; if (document.documentElement && document.documentElement.clientHeight && document.documentElement.clientWidth)    {        sWidth = document.documentElement.clientWidth;        sHeight = document.documentElement.clientHeight;    }    else    {        sWidth = screen.availWidth - 20;//防止溢出         if(screen.availHeight > document.body.scrollHeight){          sHeight = screen.availHeight; //少于一屏         }else{          sHeight = document.body.scrollHeight; //多于一屏         }    } //创建遮罩背景 var maskObj = document.createElement("div"); maskObj.setAttribute('id','maskdiv'); //maskObj.setAttribute('onclick','CloseMsg()'); maskObj.style.position = "absolute"; maskObj.style.top = "0"; maskObj.style.left = "0"; maskObj.style.background = "#fff"; maskObj.style.filter = "Alpha(opacity=40);"; maskObj.style.opacity = "0.4"; maskObj.style.width = sWidth + "px"; maskObj.style.height = sHeight + "px"; maskObj.style.zIndex = "10000"; document.body.appendChild(maskObj); //创建弹出窗口 var msgObj = document.createElement("div") msgObj.setAttribute("id","msgdiv"); msgObj.setAttribute("onClick","CloseMsg()"); msgObj.style.position ="absolute"; sWidth = 230; sHeight = 180; msgObj.style.width = sWidth + "px"; //msgObj.style.height = sHeight + "px"; var event = getEvent();//申明event if(CheckBrowser()=='IE') {  //posLeft = event.clientX + 10;    //posTop = event.clientY + document.documentElement.scrollTop;  posLeft = (document.documentElement.clientWidth - sWidth) / 2 + "px";  posTop = 50 + document.documentElement.scrollTop + "px";  //posTop = (document.documentElement.clientHeight- sHeight) / 2 + "px"; } else {  //posLeft = event.pageX + 10 + "px";//ff下要申明px  //posTop = event.pageY + 10 + "px";  posLeft = (document.documentElement.clientWidth - sWidth) / 2 + "px";  posTop = 50 + document.documentElement.scrollTop + "px";  //posTop = (document.documentElement.clientHeight- sHeight) / 2 + "px"; } msgObj.style.top = posTop; msgObj.style.left = posLeft; msgObj.style.fontSize = "18px"; msgObj.style.background = msgbg; msgObj.style.border = "1px solid " + bordercolor; msgObj.style.zIndex = "10001"; //创建内容 var bodyObj = document.createElement("div"); bodyObj.setAttribute("id","msgbody"); bodyObj.style.padding = "10px"; bodyObj.style.lineHeight = "1.5em"; bodyObj.style.color = msgcolor; bodyObj.style.textAlign = "center"; //var txt = document.createTextNode(content); //bodyObj.appendChild(txt); bodyObj.innerHTML = content; //生成窗口 document.body.appendChild(msgObj); $xp("msgdiv").appendChild(bodyObj); if(time != '') t=setTimeout("CloseMsg()",time); else t=setTimeout("CloseMsg()",3000);//默认三秒后自动消失 return false;}//移除对象function CloseMsg(){ $xp("msgdiv").removeChild($xp("msgbody")); document.body.removeChild($xp("msgdiv")); document.body.removeChild($xp("maskdiv"));   clearTimeout(t);//停止计时器 t = null; if(argl>3) {funcf();}//执行外部传入的函数}//判断浏览器类型function CheckBrowser(){    var cb = "Unknown";    if(window.ActiveXObject){        cb = "IE";    }else if(navigator.userAgent.toLowerCase().indexOf("Firefox") != -1){        cb = "Firefox";    }else if((typeof document.implementation != "undefined") && (typeof document.implementation.createDocument != "undefined") && (typeof HTMLDocument != "undefined")){        cb = "Mozilla";    }else if(navigator.userAgent.toLowerCase().indexOf("Opera") != -1){        cb = "Opera";    }    return cb;}
