JS Note 17

1, the string can be encoded as a URI component encodeURIComponent (encodeURIComponent (6)) This is encoded two times

The encodeURIComponent () function escapes punctuation marks used to separate portions of the URI.

Escape () escapes all incoming strings in addition to ASCII letters, numbers, and specific symbols, so it is best not to use this method if you want to encode the URL. encodeURI () is used to encode the entire URI because the legitimate characters in the URI are not converted by encoding. The encodeURIComponent method encodes a single uricomponent (the request parameter) should be the most common, it can be described in the parameters of Chinese, special characters escaped, without affecting the entire URL.
