1元支付源码_一元支付木马

制作一个像1元云购这样的app多少钱

无论是怎么样的软件，都是付源有bug的，所以网络上承诺的码元木马viovo系统源码功能很强的，都不可能帮你解决所以问题，支付所以大部分是元支php 网页加密源码不断的修改源码，处理各类bug，付源源码是哪个原增加个性化的码元木马功能，因此除非你自己懂技术，支付或者有技术合作伙伴，元支否则你会很麻烦，付源另外现在的码元木马云购支付也是在打擦边球，以后会不会整顿还不知道。支付最后说一下本人做云购这套系统，元支快捷指令网页源码包括原生安卓和ios app已经将近2年，付源也不敢保证给别人装一套系统一劳永逸。码元木马再创辉煌指标源码

求一元二次方程JAvascript

以下是全部的源代码,经过火狐3.和IE7测试，绝对符合你的要求

<html>

<head>

function jisuan(){

var a=parseInt(document.getElementById("a").value);

var b=parseInt(document.getElementById("b").value);

var c=parseInt(document.getElementById("c").value);

var x1=document.getElementById("x1");

var x2=document.getElementById("x2");

var inf=document.getElementById("inf");

inf.value="小提示:此方程的解应经求出";

var xx1=(-b-Math.pow(b*b-4*a*c,0.5))/(2*a);

var xx2=(-b+Math.pow(b*b-4*a*c,0.5))/(2*a);

x1.value="x1= "+xx1;x2.value="x2= "+xx2;

if(x1.value=="x1= NaN"){ inf.value="小提示:此方程无解";}

if(a+b+c!=a+b+c){ inf.value="小提示:a,b,c只能是数字";}

}

</script>

</head>

<body>

<form>

<input id="a" type="text" value="a" size="3"/>x*x+

<input id="b" type="text" value="b" size="3"/>x+
