javascript:

    function deleteentry(rowid){         document.getelementbyid('rowid').value=rowid;         document.forms[0].action='/app/protected/mflc/unavailability/delcounselorentry.action?method=deletecounselorunavailability';         document.forms['myform'].submit; //correction            } 

struts form bean:

<form-bean name="myformbean" type="org.apache.struts.action.dynaactionform"> <form-property name="mylist" type="java.util.list"/> </form-bean> 

struts delete mapping:

<action path="/unavailability/delcounselorentry"         type="com.action.myaction"          scope="request"         parameter="method"          name="myformbean">         <forward name="success"             path="/unavailability/mydeletecomfirmationpage.actioncontent" />     </action> 

any appreciated, thanks

i found reason why form undefined

i had @ first points first form:

document.forms[0];              //first <form> element 

but if have name form, need point form this:

document.forms['myform']; //points <form name="name_of_form">
