Accetta testo sorgente che contiene `'; var component = await NEWCOMPONENT(source); component.debugger = false; var instance = component.create(); var first = await new Promise(resolve => instance.input('input',{name:'Ann'},message => resolve(message.data))); var invalid = await new Promise(resolve => instance.input('input',{},message => resolve(message.data))); instance.reconfigure({prefix:'two:'}); var second = await new Promise(resolve => instance.input('input',{name:'Bob'},message => resolve(message.data))); instance.remove(); var rejected = false; try { await NEWCOMPONENT('no backend script'); } catch (e) { rejected = true; } $.json({first:first,invalid:invalid,second:second,remaining:component.instances.length,closed:MAIN.componentClosed,rejected:rejected}); } catch (e) { $.invalid(e); } } ```
