Web浏览器显示正确的值，但是当我使用Jsoup时，HTML没有值

Question

I'm trying to get some values from a site but these values only appears when I use a Browser, like Mozilla. When I use the Jsoup I can get the HTML from the site but without values, only with the tags.

This is the site I'm trying to parse:

http://www.submarinoviagens.com.br/Passagens/selecionarvoo?Origem=nat&Destino=mia&Data=05/11/2012&Hora=&Origem=mia&Destino=nat&Data=09/11/2012&Hora=&NumADT=1&NumCHD=0&NumINF=0&SomenteDireto=0&Cia=&SelCabin=&utm_source=&utm_medium=&utm_campaign=&CPId=

I'm trying to get the values that appears inside these span tags:

If I access the previous URL from a web browser I can see the following values: '', 'R$ 2634,22' and 'R$ 2634,22', but when I use the following code the values disapears.

URL url = new URL("http://www.submarinoviagens.com.br/Passagens/selecionarvoo?Origem=nat&Destino=mia&Data=05/11/2012&Hora=&Origem=mia&Destino=nat"+
            "&Data=09/11/2012&Hora=&NumADT=1&NumCHD=0&NumINF=0&SomenteDireto=0&Cia=&SelCabin=&utm_source=&utm_medium=&utm_campaign=&CPId=");
Document doc =  Jsoup.parse(url, 100000);
String title = doc.title(); 
System.out.println(doc.toString());

If I try to see the source code via Mozilla Firefox the values disapears too. But If I use the firebug plugin I can see them.

Thank's for the help!

Answer 1

The website uses JavaScript to populate all of the values you are trying to parse. You will have to use a library that can compute the javascript within the page. Not sure if there is one though.

anyone else?

Htmlunit是一种无头浏览器，可呈现Javascript，并且应该能够正确显示此页面。
