AW: Example to use javascript to validate field input in JSP not null and be integer ?

[juraj Lenharcik <ju...@datainput.de>]

why not server side? with ActionForm and validate?

jsp:
=====
<form:form action="chart.do" method="get" >
<tr>
<td  colspan="2"><font color="red"><html:errors property="datumFrom"
/></font></td>
</tr>
<tr>
<td>Datum von: </td>
<td><form:text property="from" size="15"/></td>
<tr>
...

the form bean:
=====

public ActionErrors validate(ActionMapping mapping, HttpServletRequest
request) {
	    ActionErrors errors = new ActionErrors();
	    
	    if (from == null || from.length() == 0 || blabla = blubb) {
	      errors.add("datumFrom", new
ActionError("error.filter.datum")); 
	    }
	    return errors;
	}

and the struts config:
====================

  <action path="/chart" 
     		type="di.workerClient.action.ActionFilter" 
     		name="filter"
     		scope="request"    
==>    when failure return to form	:	input="/cstree/content.jsp"
<==
   		validate="true" >
		<forward name="view" path="/cstree/chartcontent.jsp" />
		<forward name="fehler" path="/cstree/content.jsp" />
	</action>
