When running on IE11, the browser screen becomes inoperable.

[rnanba]

Browsing http://slowe.github.io/VirtualSky/ or https://slowe.github.io/VirtualSky/custom with Internet Explorer 11 hungs up the browser screen.

When I checked whith the vevelopment tool, loading of the language file en.json was repeated infinitely.

The cause of this problem is that following line in stuquery.js causes an error on IE11.

VirtualSky/stuquery.js

Line 466 in 501dc07

if(typeof rsp==="string") rsp = JSON.parse(rsp.replace(/[\n\r]/g,"\\n").replace(/^([^\(]+)\((.*)\)([^\)]*)$/,function(e,a,b,c){ return (a==cb) ? b:''; }).replace(/\\n/g,"\n"));

Replacing this line with if(typeof rsp==="string") rsp = JSON.parse(rsp); makes work fine.

replace(/^([^\(]+)\((.*)\)([^\)]*)$/,function(e,a,b,c){ return (a==cb) ? b:''; }) does not work as intended if the string value in JSON contains parentheses and return a broken JSON string, so JSON.parse() fails.

As a result, data is passed as a string value to the loadJSON()'s handler in loadLanguage() of virtualsky.js, so the following assignment opreration fails.

VirtualSky/virtualsky.js

Line 1105 in 501dc07

this.langs[l].loaded = true;

As a result, this.langs[code].loaded in the following line becomes undefined, loadLanguage() is called again, and the same language file is loaded infinitely.

VirtualSky/virtualsky.js

Line 1130 in 501dc07

if(!this.langs[code].loaded) this.loadLanguage(code,fn);
