How do I turn every chactor into %xx style?

[ok]

I tried escape, but it is only good for the special ones like : / ' space
etc. I want to turn every charactor into %xx then document.write them.

I wonder if i can double % them so I can turn @ into %40, then %%xx%yy xx is
for 4 and yy is for 0.

Thanks

<script type='text/javascript'>

function toPerc(t){
var tt = '';
for (var i=0;i<t.length; i++){
tt += "%"+t.charCodeA t(i);
};
return tt;
}

document.write( toPerc('Blah blah'));

You could, but html cannot read that.

did you try?

Not really sure what you are trying to do here - encode is dpreciated
in favour of encodeURI. If you are after a way of obfuscating your
code, Google "javascript encode"

Have a look at the link below, it includes a script to convert all
characters into their JavaScript encoding. Note that the encoding for
normal numbers and alphas is themselves,
i.e. the encoding for "a" is "a".

http://lab.artlung.com/scripting/urlencode/

Checkout encodeURI too.

Cheers, Fred.

should be in hex, doubt that it is... Also, it should be *two* hex
digits afaik, ie. %a%b%c is wrong.

Has nothing to do with HTML, but what your browser can do. And it can't.

You are right, if the html standard expects hex. And it does. ;-)

=============== ==============

<script type='text/javascript'>

var r = '0123456789ABCD EF'

function toPerc(t){
var tt = '';
for (var i=0;i<t.length; i++){
x = t.charCodeAt(i)
tt += "%"+r.subst r(x/16,1)+r.substr( x%16,1);
};
return tt;
}

document.write( toPerc('123Blah blah'));

</script>

It has nothing to do with HTML, but with URI encoding.

:-D.

function toPerc(t){
var tt = '', hex;
for (var i = 0; i < t.length; ++i) {
tt += '%' + (hex = ('0' +
t.charCodeAt(i) .toString(16).t oUpperCase())). substring(hex.l ength - 2);
}
return tt;
}
document.write( toPerc('123\t\0 Blah blah'));

Avoids a "magic" string containing the available hex digits.

I wanted to use:

tt += '%' + ('0' +
t.charCodeAt(i) .toString(16).t oUpperCase()).s ubstr(-2);

which would have avoided the awkward assignment to "hex", but IE doesn't
respect the substr() contract as far as negative first parameters are
concerned.
