本文实例为大家分享了JavaScript实现网页计算器的扫雷游戏的具体代码，供大家参考，具体内容如下
先看效果：
此外，计算器还附有数字、运算符检查功能：

var oper1=prompt("请输入第一个操作数：");
var oper2=prompt("请输入第二个操作数：");
var operator=prompt("请输入运算符（ ，-，*，/）");
parse();
var result;
switch(operator)
{
case" ":
result=doSum(oper1,oper2);
alert(oper1 " " oper2 "=" result);
break;
case"-":
result=doSubstract(oper1,oper2);
alert(oper1 "-" oper2 "=" result);
break;
case"*":
result=doMultiply(oper1,oper2);
alert(oper1 "*" oper2 "=" result);
break;
case"/":
result=doDivide(oper1,oper2);
alert(oper1 "/" oper2 "=" result);
break;
default:
alert("输入的运算符不合法");
}
function parse(){
if(isNaN(oper1)||isNaN(oper2)){
alert("输入的数字不合法");
}
else{
oper1=parseFloat(oper1);
oper2=parseFloat(oper2);
}
}
function doSum(oper1,oper2){
return oper1 oper2;
}
function doSubstract(oper1,oper2){
return oper1-oper2;
}
function doMultiply(oper1,oper2){
return oper1*oper2;
}
function doDivide(oper1,oper2){
return oper1/oper2;
}

当然，这里只展示了JavaScript源码，还可以使用html css给计算器设计好看的外观，大家随意发挥。
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持Devmax。
