Re: Refer to an by name ?

[Brice Ruth]

The form name attribute is set to the name of the ActionForm that your 
Action takes as its input. This is done automagically, without 
specifying a name="" attribute in the html:form tag itself. This is to 
support javascript validation, I believe.

Dear Struts-Community,

assumed we use a composite-view, which is composed by multiple 'tiles'
delivered by several Design-Team members. 
Every of this tile is free to define it's own form-areas (<html:form...>)
and appropriate action(s).
Furthermore we have a 'Menu-Tile' which Buttons/Links refers to certain
tiles in the content area. Clickin' such a Link should submit a certain
Action (using more than one Action within a form and therefore a
DispatchAction) in a certain form (including all the properties within the
form).

This could work like this ...

<jsp-snipet>
...
<SCRIPT>
        function callAction(targetAction) {
                setAction(targetAction);
                document.forms[0].submit();
        }
        function setAction(targetAction) {
                document.forms[0].dispatch.value=target;
        }
</SCRIPT>
...
<!-- Menu-Tile -->
...                     
        <td width="30%">
                MENU
                <br>
                <br>
                <html:link href="#" onclick="javascript:callAction( 'add'
)"> Add </html:link>
                <br>
                <html:link href="#" onclick="javascript:callAction( 'delete'
)"> Delete </html:link>
                <br>
                <html:image src="/Struts_WEB/images/fix.jpg"
onclick="callAction('fix');" />
        </td>
...
<!-- my content-Tile ..>
...
        <html:form action="/processMultiButton.do" >
		<html:hidden property="dispatch" value="error"/> 
	
		first name <html:text value="" property="firstname"/>
		last name <html:text value="" property="lastname"/>
		
		<html:submit
onclick="setAction('add');">Hinzufuegen</html:submit>
		<html:submit
onclick="setAction('delete');">Entfernen</html:submit>

                <html:image src="/Struts_WEB/images/fix.jpg"
onclick="setAction('fix');" />
        
        </html:form>      
...
<!-- here comes another contet-Tile with another form-definition and so on
-->
...
</jsp-snipet>
My Problem is the fact, that i have to refer to a certain form by an index
(document.forms[0]...) but not by name (document.forms[myFormName]).
Since we have more than one form in the content area (and this could change
dynamically, so i do not know how many form definitions we have after all)
it is not assured that i always refer for sure to the same form by using an
index. 
If i could assign a name to a form-definition (like <form
name="myFormName"...> - see 'pure HTML form-tag attributes') than the
position of the form within the content-area would be irelevant since i
refer to that certain form by using its name, like ...

<snipet>

function callAction(targetAction, formName) {
        document.forms[0].dispatch.value=targetAction;
        document.forms[0].submit();
}
...
<!-- Menu-Tile -->
...
<html:link href="#" onclick="javascript:callAction( 'delete', 'myFormName'
)"> Loeschen </html:link>
...
</snipet>
...but the <html:form ...> tag does not offer an attribute to set a forms
name ...
Is there any chance to achive this (refer to a form by name but not by
index) or may be another / better solution for this problem? Any help is
appreciated !!! :o)
Thanks in adcance :o))
