Question

I have a variable map in a database which is being returned and i want to display the details on a web page, the front end is struts2.
I tried this

 <html:iterator value="fields" id="field">
    <html:textfield name="#field.value" key="#field.value" label="#field.key"/> 
</html:iterator>

obviously this didn’t work, how can i get the Key Name easily so i can have code like this

The idea is to display as follows

Name: [  ]
Random: [  ]
Something: [   ] 

as textfields in a form…

How can i do this simply?

Answer 1

Well not sure how to do it in <html:iterator> as never saw it in struts2 tag libor have not came across it.

will use simple <iteraor> tag

assuming we have listmap as map

<s:iterator value="listmap" status="stat">
                    <s:iterator>
                        <tr>
                            <th><s:property value="#stat.index"/></th>
                            <td><s:property value="key"/></td>
                            <td><s:property value="value"/></td>
                        </tr>
                    </s:iterator>
                </s:iterator>

inner iterator is context sensitive it will use the last value pushed onto the stack. The status attribute gives us a IteratorStatus object each iteration which is useful if we want to know the current iteration.
