escape() 方法：
采用ISO Latin字符集對指定的字符串進行編碼。所有的空格符、標點符號、特殊字符以及其他非ASCII字符都將被轉化成%xx格式的字符編碼（xx等于該字符在字符集表里面的編碼的16進制數字）。比如，空格符對應的編碼是%20。unescape方法與此相反。不會被此方法編碼的字符： @ * / +
英文解釋：MSDN JScript Reference: The escape method returns a string value (in Unicode format) that contains the contents of [the argument]. All spaces, punctuation, accented characters, and any other non-ASCII characters are replaced with %xx encoding, where xx is equivalent to the hexadecimal number representing the character. For example, a space is returned as "%20."
Edge Core Javascript Guide: The escape and unescape functions let you encode and decode strings. The escape function returns the hexadecimal encoding of an argument in the ISO Latin character set. The unescape function returns the ASCII string for the specified hexadecimal encoding value.
encodeURI() 方法：把URI字符串采用UTF-8編碼格式轉化成escape格式的字符串。不會被此方法編碼的字符：! @ # $& * ( ) = : / ; ? + '
英文解釋：MSDN JScript Reference: The encodeURI method returns an encoded URI. If you pass the result to decodeURI, the original string is returned. The encodeURI method does not encode the following characters: ":", "/", ";", and "?". Use encodeURIComponent to encode these characters. Edge Core Javascript Guide: Encodes a Uniform Resource Identifier (URI) by replacing each instance of certain characters by one, two, or three escape sequences representing the UTF-8 encoding of the character
encodeURIComponent() 方法：把URI字符串采用UTF-8編碼格式轉化成escape格式的字符串。與encodeURI()相比，這個方法將對更多的字符進行編碼，比如 / 等字符。所以如果字符串里面包含了URI的幾個部分的話，不能用這個方法來進行編碼，否則 / 字符被編碼之后URL將顯示錯誤。不會被此方法編碼的字符：! * ( )
