Some time ago read "JavaScript Advanced program Design" finally found a little introduction:
\xnn a character (n:0-f) expressed in hexadecimal code nn
\UNNN A Unicode character (n:0-f) in hexadecimal code
Today because one of their own needs to know the hexadecimal representation of some Chinese characters, so you write two methods, you can convert the text to a 16-way representation, you can convert the 16-code into Chinese characters. The method is as follows:
Copy Code code as follows:
Convert Text to 16
function Texttosix (str) {
return Escape (str). replace (/%/g, function () {
return "\";
}). toLowerCase ();
}
To represent a 16 binary as text
function Sixtotext (str) {
return unescape (str);
}
