i18n.properties & end-user language auto-detection since 2.6

[support]

Hi all,

Since release 2.6, we had to remove end-user language auto-detection (based on locale) from the applet to get rid of a security warning displayed for JRE 1.6.0_19+. JFileUpload still supports multiple languages but you have to define which resources file to load in JavaScript now. To do so you have update the JavaScript slightly by adding the following lines at the beginning of the JavaScript:

Code: Select all

// Language detection
var _language = (navigator["language"])?navigator["language"]:navigator["userLanguage"];
var _file = "i18n";
if (_language.indexOf("en")>=0) _file = _file + "_en";
else if (_language.indexOf("es")>=0) _file = _file + "_es";
else if (_language.indexOf("de")>=0) _file = _file + "_de";
else if (_language.indexOf("fr")>=0) _file = _file + "_fr";
else if (_language.indexOf("cn")>=0) _file = _file + "_cn";
// _file value can be used for "resources" parameter.

And then update the following lines too:

Code: Select all

...
document.write('resources="'+_file+'" ');
...
document.writeln('<PARAM NAME="resources" VALUE="'+_file+'">');

This sample assume that you what the following .properties files in the same folder as the HTML/Javascript (i.e. document base).
i18n.properties
i18n_cn.properties
i18n_de.properties
i18n_fr.properties
i18n_es.properties
i18n_en.properties
