Joey!
I had this problem earlier and I fixed it now..
What you need to have in your action form is..
public Row getRow(int index) {
return (Row) rows.get(index);
}
public void reset(ActionMapping mapping, HttpServletRequest
servletRequest) {
// struts check boxes do not remember the values when changed
from true to false,
// reset everything before setting true/false
for (int i = 0; i < rows.size(); i++) {
Row row = (Row)rows.get(i);
row. setIsSelect (false);
}
}
And in your jsp you can use
<logic:iterate id="rows" name="yourActionForm" property="rows"
type="yourClass" indexId="ctr">
<html:checkbox property='<%= "rows[" + ctr + "].
isSelect "%>' />
</logic:iterate>
I hope this helps.

Subject: How to use checkbox in struts.
Hello everybody.
I think this is a old question. but I can not find a good and complete
example in Google.
My question is :
I have a Jsp page which will list some datas for user. user can
choose(by
click the checkbox) some of those data and click a botton for delete or
some
others operator. So I think my Action class , ActionForm , data class
and
JSP will like this.
----------------------------------------------------------------------
Row {
private String isSelect;
public getIsSelect() {
}
public setIsSelect() {
}
}
--------------------------------------------------------------------
ActionForm {
private ArrayList rows; //dynamic
public get....
public set...
}
---------------------------------------------------------------------
Action {
...
for (int i = 0; i < ActionForm.rows.size; i++){
Row row = ActionForm.rows.get(i);
if ( row.isSelect =="check" ) {
//Do some thing here.
}
}
}
....................................................................
JSP page.
I have to use <input type = "checkbox"> or <Html:Checkout> for data
list.
datas quantity is not fix.
can not use <html:Mutibox>
and I need use a botton commit data to Action.
--------------------------------------------------------------------
my problem is :
1. In Row class. If define isSelect as a String , is it ok, or boolean
is
better?
2. I don't know how to write <input type = "checkbox"> or
<Html:Checkout> to
make a checkbox, and make action can know whick is be selected.
Thanks for any help.
Joey
