how to access all checkboxes that have a name that begins with "abc"?

[Dennis Haupt]

hi community, 

i'm in a gwt module that is part of a bigger page, and i need to know which checkboxes that are on this page are selected. i know what the names of these boxes are, but i don't know how many there are.

how can i a) get them all and b) find out which ones are checked from inside my gwt entry point?

One way is build your own collection (ArrayList) and make accessible,
with setter and getter ,just like in any java class.

[Aidan O'Kelly]

import com.google.gwt.dom.client.Document;
import com.google.gwt.dom.client.Element;
import com.google.gwt.dom.client.NodeList;
.
.
.
NodeList<Element> elementList = Document.get().getElementsByTagName("input");

This will give you a list of all HTML 'input' elements on the page,
you can loop through them and check the type/id/value of the element
for the ones you are interested in.

I guess you have to use something like:

for(Element e : Document.get().getElementsByTagName("input")) {

 if(e instanceof InputElement) {

   InputElement ie = (InputElement) e;

   if("checkbox".equals(ie.getType()) && ie.getName().startsWith("abc") && (ie.isChecked() || ie.isDefaultChecked())) {

      //do your stuff here

   }

 }

}

I haven't tried it but it should check every input element if its a checkbox, its name starts with "abc" and if its checked.

gQuery will be a good tool choice

and how do i get them in the first place? i don't create them, they
already exist on the page
