[Htmlunit-user] RE: Help with Options

[Vijay N. <VNa...@ma...>]

Danny,

I tried the getOption(int i) method. It gave me "no such method exception "

I am able to get a List of Options by calling getAllOptions();

Since none of these options have a "VALUE" selecting the option fails and
also the getValueAttribute()


The following is the code snippet I use and the error I got

//CODE SNIPPET
    
final HtmlSelect max = (HtmlSelect)form.getSelectByName("MAXDOCS");
List maxopts=max.getAllOptions();

System.out.println(maxopts.size());

for(int i=0; i<maxopts.size(); i++){

 System.out.println(maxopts.get(i));
    
}
HtmlOption maxopt=(HtmlOption)maxopts.get(1);
maxopt.setSelected(true);
System.out.println("CHOICEMAX : "+maxopt.getValueAttribute());


//ERROR MESSAGE

Hi Vijay,

There's a method called getOption(int i) that looks like it should do 
the trick.  Or you can run through all the options with 
getAllOptions(), and choose the right one by looking at each option's 
getValueAttribute(), I think.

 From what I understand, the value of each option should default to the 
text content.  So you should see those four options, and each 
com.gargoylesoftware.htmlunit.html.HtmlOption should have a 
getValueAttribute().

Good luck to you!
