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 <= ? "发送验证码" : ("" + (time) + "秒"));
var hander = setInterval(function () {
if (time <= ) {
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");
}
}, );
} //绑定手机号码
function go() { var phone = $("#phone").val();
if (phone == "" || phone == "请输入11位手机号码" || phone == null) {
NewAlertBox("warning", "请输入11位手机号码", );
return;
} var myreg = /^((([-]{})|([-]{})|([-]{}))+\d{})$/;
if (!myreg.test($("#phone").val())) {
NewAlertBox("warning", "请输入有效的手机号码!", );
$("#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!", );
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!", , function () { WeixinJSBridge.call('closeWindow'); });
// }
// else {
// NewAlertBox("warning", data.msg, 3000, function () { WeixinJSBridge.call('closeWindow'); });
// }
// }
// }); } //获取验证码
function getverify() {
var phone = $("#phone").val();
if (phone == "" || phone == "请输入11位手机号码" || phone == null) {
NewAlertBox("warning", "请输入11位手机号码", );
return;
} var myreg = /^((([-]{})|([-]{})|([-]{}))+\d{})$/;
if (!myreg.test($("#phone").val())) {
NewAlertBox("warning", "请输入有效的手机号码!", );
$("#phone").val("");
return;
} timer();
// $.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!", );
// } 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:
/*

*/
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[];
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>)

if(itype.toUpperCase()=='OK') //提示通过

else if(itype.toUpperCase()=='ERROR') //提示报错

var event = getEvent();//申明event
if(CheckBrowser()=='IE')

//posLeft = event.clientX + 10;
//posTop = event.clientY + document.documentElement.scrollTop;
posLeft = (document.documentElement.clientWidth - sWidth) / + "px";
posTop = + document.documentElement.scrollTop + "px";
//posTop = (document.documentElement.clientHeight- sHeight) / 2 + "px";
}
else

}
msgObj.style.top = posTop;
msgObj.style.left = posLeft;
msgObj.style.fontSize = "18px";
msgObj.style.background = msgbg;
msgObj.style.border = "1px solid " + bordercolor;

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()",);//默认三秒后自动消失
return false;
}
//移除对象
function CloseMsg(){
$xp("msgdiv").removeChild($xp("msgbody"));

clearTimeout(t);//停止计时器
