簡(jiǎn)單的計(jì)算器代碼

作為初學(xué)者能寫(xiě)出一個(gè)簡(jiǎn)單的程序再開(kāi)心不過(guò)了。下面小編給大家介紹一個(gè)簡(jiǎn)單的計(jì)算器代碼程序。

#box{width: 295px; margin: 0 auto; text-align: justify; border: 1px solid #ddd; padding: 15px;}

.d_num{display: inline-block; margin: ?10px; width: 33px; height: 30px; border: 1px solid #ddd; text-align: center; line-height: 30px; cursor: pointer;}

.sum{margin: 0 10px 10px; line-height: 30px; font-size: 20px;}

#sum{width: 205px; height: 30px; padding: 0 5px; margin-left: 5px; font-size: 20px;}

#process{width: 255px; height: 30px; padding: 0 5px; margin-left: 5px; font-size: 20px;}

SUM:

1 2 3 <- C

4 5 6 * /

7 8 9 + -

0 00 . % =

var $box = document.getElementById('box');

var $sum = document.getElementById('sum');

var $process = document.getElementById('process');

var sum = 0, process = '', num1 = '', num2 = '', temp = '', statu = false;

$box.onclick = function(e){

var event = window.event || e;

var ele = event.srcElement || event.target;

var _className = ele.className;

if(_className == 'd_num'){

var num = ele.getAttribute('data-num');//點(diǎn)擊的.按鈕對(duì)應(yīng)的值

var NotNum = isNaN(num);

if(!NotNum || num == '.'){ //點(diǎn)擊了數(shù)字

if(!statu){ //還沒(méi)點(diǎn)擊過(guò)符號(hào)

if(num1 == '0'){

num1 = '';

}

num1 += num;

process = num1;

}else{ //已經(jīng)點(diǎn)擊過(guò)符號(hào)

if(num2 == '0'){

num2 = '';

}

num2 += num;

process = num1 + temp + num2;

}

$process.value = process;

}

else{ //點(diǎn)擊了符號(hào)

if(num1 == ''){//非法操作

return false;

}

if(num == 'C'){//歸零

num1 = '';

num2 = '';

process = '';

temp = '';

sum = '';

$process.value = '0';

$sum.value = '0';
