Hello, China!

encodeURI(b):
Hello,%20China!
encodeURIComponent(b):
Hello%2C%20China!
escape(b):
Hello%2C%20China%21

escape()编码,不能编码URI unescape()解码,不能编码URI encodeURIComponent()编码范围比encodeURI大些 decodeURIComponent()解码范围比encodeURI大些 encodeURI()对一个URI编码 decodeURI()对一个URI解码 isFininte()检测表达式的值,如果不是无穷大或NaN则为True isNaN()判断是否NaN confirm()确认取消对话框 prompt()带输入信息的对话框 paraseFloat()转换成小数 paraseInt()转换成整数
