At this time, encodeURIComponent and decodeURIComponent appeared, which can completely encode and decode URLs. However, when encountering partial transcoding used by search engines, for example, it is difficult to find the door. No problem, PHP officially has a solution:

Copy code The code is as follows:

decodeURIComponent((str '').replace(/ / g, ' '));

It can perfectly decode the address of the search engine, because the search engine is only used to transcoding "spaces". Forgot to mention that I am also used to transcoding Chinese. . .
Then all the above solutions collapsed when encountering Chinese. Yes, I also collapsed. It was partially encoded and it was Chinese. . This makes me feel so embarrassed. . .

return str. charCodeAt(0).toString(16);
}
function asc2str(str){
return String.fromCharCode(str);
}
