decodeURI和decodeURIComponent

函数编码的 URI 进行解码。

encodeURI（）：用于编码完整的URI，它不对URI中的特殊字符进行解码：例如冒号、前斜杠、问号、英镑符号

decodeURIComponent（）：用于编码完整的URI，它不对URI中的特殊字符进行解码：例如冒号、前斜杠、问号、英镑符号

encodeURI和encodeURIComponent

可把字符串作为 URI 进行编码。encodeURI()和encodeURIComponent()的用法基本相同，区别在于encodeURIComponent()也对”?”等特殊字符进行编码。

JSON.stringify

js：数组转json

JSON.parse

js：json转数组
