Hello,
i want to call an action by javascript, when a value in a <html:select> field changes. I want to fill my <html:form> with the data provided by the action. Any ideas?

I don't know a lot of javascript :-( There's a couple if ways you could do that... one would be to call the submit() method of the form object, which every form in HTML has, then re-render the page with the updated data in the form. That's of course going to refresh the entire page, which I suspect isn't what you want. So, AJAX is probably what you want. Now, how you go about doing that, well, there's a few hundred options :) Because you don't know a lot of Javascript, you might want to consider the AjaxParts Taglib (APT) from Java Web Parts (JWP): http://javawebparts.sourceforge.net Direct to APT: http://javawebparts.sourceforge.net/javadocs/javawebparts/ajaxparts/taglib/package-summary.html If you go to the download page, the cookbook has some examples that are very much along the lines of what you're asking for. If you go that route, we'll be more than happy on the JWP mailing list, or forums. Otherwise, prototype (http://www.prototypejs.org) is a good, simple option, but you will be writing some Javascript. > thanks & greetings from Berlin hth, Frank --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscribe@...

Hello,
now i am using the javawebparts.ajaxparts and when i put all the things in a whole jsp-site, than the ajax is working: <%@ taglib prefix="ajax" uri="javawebparts/ajaxparts/taglib" %> <?xml version="1.0" encoding="ISO-8859-1" ?> <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" /> <title>Insert title here</title> </head> <body> <form action="#"> <input id="btn" type="button" value="TESTBUTTON"/><ajax:event ajaxRef="employee/update" attachTo="btn"/> </form> <div id="result-div"> </div> <ajax:enable/> </body> </html> But when i am using it with struts-tiles than it doesn't work :-( - i think that's because the target in the ajax-config is not found. I don't now why. Without tiles, the target will be found. The index-result.txt is in the same directory as the jsp-site. <ajaxConfig> <group ajaxRef="employee"> <element ajaxRef="update"> <event type="onclick"> <requestHandler type="std:SimpleRequest" target="index-result.txt"> <parameter /> </requestHandler> <responseHandler type="std:InnerHTML"> <parameter>result-div</parameter> </responseHandler> </event> </element> </group> </ajaxConfig> When i use an action as a target, it doesn't work, too (e.g. target="action.do?parameter=xxx¶m2=yyy). I use the DispatchAction, so with the parameter I can delegate or specifiy the method, which will be called in my action... Any ideas? Thank's a lot!! Greetings from Berlin Frank W.

ok, the Text in the index-result is working now, but i want to use the
actions and when i use parameters like "/employee.do?task=update&ajax=getEmployee" then there comes an error message "The reference to entity "ajax" must end with the ';' delimiter."

Can you tell where that error is coming from? I don't recognize it as
an APT error, so I'm guessing Struts, but I don't recall ever seeing that before. You know what... what happens if you remove the <?xml> and <!DOCTYPE> tags? Does it work then?

I referred to the manual and there it suggested to use "parameter"
instead, like this: <requestHandler type="std:QueryString" target="/ajax.do"> <parameter>value=name</parameter> </requestHandler> then you can use: String value = (String) request.getParameter("value"); Now i have another problem :-)) I want to use the "std:FormManipulator" als ResponseHandler, but I have problems with the correct XML-Response-Format and i don't find any code example for that. I am generating the form by using the struts-tags <html:form>,<html:txt> and so on. And with the FormManipulator i think i can manipulate the generated form. The other way maybe is that i generate my form like <html type="text" value="<% ..... %>" after the <ajax:event> called my action and my action puts me a bean into the request.

Re: struts 1.2: calling an action by ajax (javawebparts)

I would suggest joining the JWP mailing list and re-posting this
question there... the form manipulator handler was written by a member of the JWP team named Herman, and I know he'd be able to help you out quickly. I think though that there is an example of that handler in the JWP sample application that comes with the distribution, if memory serves, you may want to check that out first. If it's no help, moving to the JWP mailing list would probably be a good idea at this point since this isn't so much Struts-related any more.

Rate this Message:
Yes, you can do so by using AJAX, you need to invoke a Javascript function that makes an AJAX call to the action.
