Check-boxes and formbeans
Hi All,
I have many checkboxes with the same name in my html form. I use struts
framework. When i submit the form, will i be able to access the
checkboxes as an array in the form bean? Or should i have a seperate
field for each checkbox in the formbean?
Regards
Vasudevrao gupta

And it wont populate the unchecked ones... which means if each checkbox
doesnt have a unique value (ie: they all have value "true" or "on") you will
get an array containing n instances of "on" where n is equal to the number
of checked checkboxes of that name. Not very helpful.
Best bet is to give them individual values, or individual names, so you can
tell them apart when submitted.
ie: submission of the following:
<input type="checkbox" name="bob" value="on" checked="checked"/>
<input type="checkbox" name="bob" value="on"/>
<input type="checkbox" name="bob" value="on" checked="checked"/>
<input type="checkbox" name="bob" value="on" checked="checked"/>
<input type="checkbox" name="bob" value="on" checked="checked"/>
will give you:
bob == String[] { "on","on","on","on" }
The idea is to use something like:
<input type="checkbox" name="bob" value="1" checked="checked"/>
<input type="checkbox" name="bob" value="2"/>
<input type="checkbox" name="bob" value="3" checked="checked"/>
<input type="checkbox" name="bob" value="4" checked="checked"/>
<input type="checkbox" name="bob" value="5" checked="checked"/>
which will give you:
bob == String[] { "1","3","4","5" }
OR
<input type="checkbox" name="bob1" value="on" checked="checked"/>
<input type="checkbox" name="bob2" value="on"/>
<input type="checkbox" name="bob3" value="on" checked="checked"/>
<input type="checkbox" name="bob4" value="on" checked="checked"/>
<input type="checkbox" name="bob5" value="on" checked="checked"/>
bob1 == "on"
bob2 == null (assuming you reset it or its a request scoped form etc...)
bob3 == "on"
bob4 == "on"
bob5 == "on"
OR (maybe)
You could probably make use of indexed property names too (and init the
array of appropriate length in the reset method)
<input type="checkbox" name="bob[0]" value="on" checked="checked"/>
<input type="checkbox" name="bob[1]" value="on"/>
<input type="checkbox" name="bob[2]" value="on" checked="checked"/>
<input type="checkbox" name="bob[3]" value="on" checked="checked"/>
<input type="checkbox" name="bob[4]" value="on" checked="checked"/>
to get:
bob == String[] { "on",null,"on","on","on" }
Though I havent tried this variant, so I could be wrong, or the semantics
could be subtly different!

hi
Just declare a property field with the datatype as array like
String[] mycheckBox
It will automatically populate all of the checkbox selected into the array
property

RE: Help needed in form beans
Posted by Robert Taylor <rt...@mulework.com>.
You may want to consider creating a separate object to hold these
values in the session and use your form beans for data input.
This way you can decide when to populate your form beans with
the data that you've captured in the session.
To control when reset() affects my form properties I subclassed
the action form and subclassed ActionMapping to add an isReset()
setReset(boolean reset) methods so I can declaratively define
when reset is to be used by adding the following line in my struts-config
file:
<set-property property="reset" value="false"/>

Help needed in form beans
Posted by vasudevrao gupta <va...@wipro.com>.
Hi All,
I have a same form bean for 5 JSP's(JSP1,JSP2,JSP3,JSP4,JSP5)
All the JSP's use the same form bean.I am keeping the form bean in the
session scope.
When ever I use JSP1, JSP3, I want to see the blank screen even if there
are some values in the formbean.
But, in other JSP's, I want to see the screen with prepopulated values.
I tried using reset() for this and I have set all the values in formbean
to null.But reset is getting called
for all the action.I want reset to be called only for JSP1,JSP3.
Please provide any direction on this

VasudevRaoGupta
