Pop up using struts

I am new to struts. I need to generate a popup window and pass values to it using struts.

I found the following code on net

javascript function onclick="passSelected()"

<input type="hidden" name="selectedItem" value=""/>

function passSelected(var)
{
alert(var);
var url='popup.do?selectedItem='+var;
window.open('url','New','height=600,width=600',200,200);
}

My doubt is how to pass this selected item as a parameter to popup.do. in the above function it is passing as a url. Can I directly access this in the action class. or do I need to use some statement as

req.getParameter("selectedItem") in the action class.

You can do

onclick="passSelected(this.yourformname.selectedItem.value)" and this should get you the value in the input with the name "selectedItem"

Thoe I am using a form data is not accessed through form as it is stored in valueobjects/transferobjects which is declared inside the form. Data is displayed in table not in controls as textbox

will not the statement req.getParameter("selecteditem" ) declared in action class work.

Then you will need ot fill the value using other means, something like

javascript function onclick="passSelected()"

function passSelected()
{
alert(var);
var url='popup.do?selectedItem='+<%=<your struts variable here>%>;
window.open('url','New','height=600,width=600',200,200);
}

> will not the statement req.getParameter("selecteditem" ) declared in action class work.

This will use the request object. You could use that as well by doing

javascript function onclick="passSelected()"

function passSelected()
{
alert(var);
var url='popup.do?selectedItem='+<%=req.getParameter("selecteditem" )%>;
window.open('url','New','height=600,width=600',200,200);
}

but you will have to set the "selectedItem" value from a *previous* page.

Thanks for the real good answer. One last question

Will the statement

var url='popup.do?selectedItem='+<%=req.getParameter("selecteditem" )%>;

pass the value of the selected item to popup.do, as I need it in popup.do. If no how to.
