/*
parseInt() 函数可解析一个字符串，并返回一个整数。
1、解析字符串，直到不能解析为止
2、进制转化中，解析字符串，直到不能解析为止
*/
document.write(parseInt("123") + "<br/>");//123
document.write(parseInt("1abc23") + "<br/>");//1
document.write(parseInt("123abc") + "<br/>");//123
document.write(parseInt("abc") + "<br/>");//NaN
document.write(parseInt("100",2) + "<br/>");//4，以二进制形式解析
document.write(parseInt("123",2));//1，因为2、3不能解析
