| Function: string llEscapeURL( string url );
|
| 参数：string url – A (preferably valid and unescaped URL) string.
|
| 返回值：Returns a string that is the escaped/encoded version of url, replacing spaces with "%20" etc. The function will escape any character not in [a-zA-Z0-9] to "%xx" where "xx" is the hexadecimal value of the character in UTF-8 byte form.
|
| 注意事项
|
| The function is not appropriate for escaping a url all at once, because the ":" after the protocol, and all of the "/" characters delimiting the various parts, will be escaped. Instead, build the url in parts; escaping parts of the path and query string arguments as needed.

示例1
string str = "http://wiki.secondlife.com/wiki/LSL Portal";
default
{
state_entry()
{
llOwnerSay("Plain string:\n\t" + str);
// output: "http://wiki.secondlife.com/wiki/LSL Portal"
llOwnerSay("Escaped string:\n\t" + llEscapeURL(str));
// output: "http%3A%2F%2Fwiki%2Esecondlife%2Ecom%2Fwiki%2FLSL%20Portal"
llOwnerSay("Escaped string unescaped again:\n\t" + llUnescapeURL( llEscapeURL(str) ));
// output: "http://wiki.secondlife.com/wiki/LSL Portal"
// because escaping and unescaping are exact opposite
// and unescaping an escaped string returns the original
// For readability's sake it would make more sense to do:
llOwnerSay("For readability's sake:\n\t" + "http://wiki.secondlife.com/wiki/" + llEscapeURL("LSL Portal"));
// output: "http://wiki.secondlife.com/wiki/LSL%20Portal"
}
