Can I pass a bean to a javascript function within a html:iterate tag?

[Kim Kantola]

Hi All,
I am iterating over a collection of objects and creating radio buttons. I would like to use info from the ReportBean object to pass to an on click javascript call as follows:

<logic:iterate id="item" name="reportsForm" type="patientFlow.app.reports.business.model.ReportBean" property="_reportBeansList"> 
<tr><td>             
   <html:radio name="reportsForm" property="_selectedReportName" value="<bean:write name='item' property='_reportName'/>" on click="enableControls(<bean:write name='item' property='_unitTypeReport'/>,<bean:write name='item' property='_dateTypeReport'/>);"/>
                      <span class="copy">
                          <bean:write name="item" property="_reportName"/>
                        </span></td></tr>
                </logic:iterate>

I would guess that when compiled, the jsp would contain the actual bean values in the javascript call, but when I do a view source on the page, I see this:

<tr><td>             
                      
                      <input type="radio" name="_selectedReportName" value="<bean:write name='item' property='_jasperReportName'/>" on click="enableControls(<bean:write name='item' property='_unitTypeReport'/>,<bean:write name='item' property='_dateTypeReport'/>);">
                      <span class="copy">
                          Admitting report
                        </span></td></tr>

instead of this:

<tr><td>             
                      
                      <input type="radio" name="_selectedReportName" value="<bean:write name='item' property='_jasperReportName'/>" on click="enableControls("unit","weekly");">
                      <span class="copy">
                          Admitting report
                        </span></td></tr>    

I am guessing maybe I have a parenthasis wrong or some other syntax problem. Can anyone spot it? I have made this work before when the item value I am passing is an integer, but now with string values being passed, this is not working as I would expect.

Whenever you see JSP elements not interpreted and passed as part of the HTML source, you can bet that something is not configured correctly. Are you sure that you have the bean TLD properly declared?

[Kim Kantola]

Thanks Bear,

I have this at the top of my jsp, is that what you mean?
<%@taglib uri="/tld/struts-bean.tld" prefix="bean"%>

Also, I do use bean:write in other spots of the page and those all resolve fine, its just when I use it inside a javascript method call upon an on click.

Oh, yeah. I'm surprised you're not getting a translation error. You cannot use actions within the attribute values of another action.

[Kim Kantola]

I guess I can use

enableControls(<%=item.get_unitTypeReport%>, <%=item.get_dateTypeReport")

But I thought including <%= %> was something that was recommended to avoid. Is it considered OK practice? If not, would you recommend a better way to access the bean value?

Thanks,
Kim

Hi,

Did you find a way to pass the <bean:write> tag to java script function?, If yes could you pl share the details. Am also stuck with same problem.

try something like this (with quotes) but say bye to scriplets,

   
    onClick="javascript:enableControls('<%=item.get_unitTypeReport%>', '<%=item.get_dateTypeReport%>') ;"/>   
 

OR your bean write should work if you use double quotes (the code you posted has single quotes). If it is still a problem, reply with js error
