JS对URL进行编码和解码

escape 和 unescape

编码：

escape('?name=zhang@xiao@jie&order=1')结果："http%3A//%3Fname%3Dzhang@xiao@jie%26order%3D1"

escape('张')结果："%u5F20"

解码：

unescape("http%3A//%3Fname%3Dzhang@xiao@jie%26order%3D1")结果："?name=zhang@xiao@jie&order=1"

unescape("%u5F20")结果："张"

encodeURI 和 decodeURI

编码：

encodeURI('?name=zhang@xiao@jie&order=1')结果："?name=zhang@xiao@jie&order=1"

解码：

decodeURI("http%3A//%3Fname%3Dzhang@xiao@jie%26order%3D1")结果："http%3A//%3Fname%3Dzhang@xiao@jie%26order%3D1"
