calling js function with list backed form value

Hi,

I have a list backed action form and want to call a javascript function with
one of the parameters to the function being a value from the list backed
action form. 

My js function is as such:

<bean:define id="jsFunction">
 javascript:calculate('<%="benefits[" + index.intValue() + "].value"%>',
                    '<bean:write name="benefit" property="benMaxRange"/>',
                    '<bean:write name="benefit" property="benMinRange"/>',
                    '<bean:write name="benefit" property="benRange"/>',
                    '<bean:write name="benefit" property="label"/>')
</bean:define>

The value I want substituted into the function is <%="benefits[" +
index.intValue() + "].value"%>

My input text tag is as such which calls the function:

<input type="text" name="<%="benefit["+index.intValue()+"].value"%>"
value="" size="20" onblur="<%=jsFunction%>"/>

Can anyone help with explaining how to get the value from the input text box
of the form and send it to the function. The text boxes name is dynamic thus
causes me problems.

The html source shows the following: benefit[0].value in the function and
not the actual value.

Thanks

Hi

Here you are using a normal input tag from html which has no knowledge of
any of the struts functionalities(mapped back properties). Use html:text
instead

Cheers,
Siva.

Re:[OT] calling js function with list backed form value

In your JS function can you add 'this' as one of the parameter. Then in 
your js function you can get the value from the element.
Like <input type="text" onclick="return someFunction(this)"/> which 
implies the element on which the event occured.
Note: I have never used <bean:xxx tags> and  don't know much about it.  
My thoughts.

Thanks,
Vijay Venkataraman
