带前导零的Javascript变量 [英] Javascript variable with leading zeroes

问题描述

JavaScript的行为与带有前导零的值不同. alert(b)-显示不同的值.

var a = 67116;
var b = 00015;
alert(a);
alert(b);

我更想知道alert(b)内部的javascript在这里应用了什么转换? (如果我将它们用双引号引起来.它们工作正常.)

解决方案

var b = 00015

是一个八进制数字

Javascript behaves differently with values having leading zeroes. alert(b) - prints different value.

var a = 67116;
var b = 00015;
alert(a);
alert(b);

I am more interested to know What conversion is applied here by javascript inside alert(b) ? (If i have them in double quotes. They work fine.)

解决方案

var b = 00015

is an octal number
