I know that it is not the exact subject of the message but I will wish to
know if somebody implemented buttons check all/uncheck all on a struts page.
So yes how?
I already posted several messages on this subject but nobody answered.
if somebody has a few minutes.
My JSP page:
<logic:iterate name="myForm" id="employees" property="employees"
type="comm.Employee" offset="offset" length="length">
<tr>
<td bgcolor="#EBEBEB" width="10%">
<html:checkbox name="myForm" property="selected"/>
</td>
</tr>
</logic:iterate>
<table width="100%" border="0" cellpadding="0" cellspacing="0"
bgcolor="#ffffff">
<tr>
<td align="right" valign="top" width="10%">
<html:button property="callId"
onclick="checkAll(this.myForm.selected)" >Checkall
</html:button>
<html:button property="callId"
onclick="uncheckAl(this.myForm.selected)" >Uncheckall
</html:button>
</td>
<tr>
</table>
<script language="JavaScript">
function checkAll(field)
{
for (i = 0; i < field.length; i++)
field[i] = true ;
}
function uncheckAll(field)
{
for (i = 0; i < field.length; i++)
field[i] = false ;
}
</script>
My struts-config.xml
<form-bean name="myForm" dynamic="true"
type="org.apache.struts.validator.DynaValidatorForm">
<form-property name="selected" type="java.lang.Boolean[]" />
</form-bean>
Thanks a lot in advance.

You will need to put conditional logic in your reset() method so that it
only resets checkbox values on the page that is being submitted and leaves
checkbox values for other pages well alone.

Subject: Resetting checkboxes in a multipage form
Hello everybody,
I'm trying to implement a multipage form, with at least one checkbox.
To solve the problem with unchecked boxes not being submitted to the server,
I implemented the reset() method to set my checkboxValue to false.
However this solution does not work in a multipage form,
as the reset() method is called for every page of my form,
even the pages where my checkbox is not on.
For ex. a 3 page form
I check the box on page1, submit and go to page 2 --> everything works fine
fill in page 2, submit and got to page3 --> not ok
reset is called --> checkboxvalue back to false, and my bean is not
repopulated with the correct value
because my checkbox was not on page2.
Does anybody know an elegant solution to this problem?
Or am I forced to put a hidden parameter with the same name/value pair as my
checkbox
on the pages where my checkbox is not on.
thx for your time,
Nicolas
