spero di non sbagliare postando qui..
ho da poco modificato una pagina html che era stata validata da validator.w3.org come conforme agli standard html 4.0
a questa pagina ho aggiunto un javascript per il detect automatico del flash player che mi sta creando non pochi problemi, in quanto non è più conforme agli standard html 4.0
la riga di codice che crea questi problemi è la seguente:
document.write('<SCR' + 'IPT LANGUAGE=VBScript\> \n');
validator.w3.org mi dice che il tag <SRC non è chiuso correttamente, siccome non conosco javascript, non so nemmeno da dove cominciare per sistemarlo.
di seguito riporto lo script completo.
ringrazio anticipatamente
Samuel
