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>
<script type="text/javascript">
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";}
}
