【原创】贡献一个JS的弹出框代码...
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    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; } //alert function 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; }
