javascript - The component is no Updating -


i'm working on i18n , button changes language spanish english , vice versa.

i have part of code before de reactdom.render works properly:

function tooglelang(){   if(localstorage["lang"]==="es"){     i18nconfig.messages=spanishmessages.messages;     i18nconfig.locale="es"   }   else if(localstorage["lang"]==="en"){     i18nconfig.locale="en"     i18nconfig.messages=englishmessages.messages   }     console.log(localstorage["lang"])     console.log(i18nconfig.messages) } console.log(tooglelang)  reactdom.render(    <intlprovider messages={i18nconfig.messages} locale={i18nconfig.locale}>          <app app={tooglelang.bind(this)}/>     </intlprovider>,     document.getelementbyid('root')   );

in app.js have inside component:

onchangelanguage(lang){    /* switch (lang) {         case 'es': i18nconfig.messages = spanishmessages.messages; localstorage.setitem("lang", "es" ); break;         case 'en': i18nconfig.messages = englishmessages.messages; localstorage.setitem("lang", "en" ); break;         default: i18nconfig.messages = spanishmessages.messages; break;     }     this.setstate({  });     i18nconfig.locale = lang;*/     if(lang==="es"){       localstorage.setitem("lang", "es" )     }     else if(lang==="en"){       localstorage.setitem("lang", "en" )      }     console.log(localstorage["lang"])     console.log(this.props.app)     }   onchange(lang){     this.onchangelanguage(lang)     this.props.app()     this.forceupdate()    }

so when click on button should change language doesn't.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
