Ajax Call from a html link
I have a jsp page named "tvshow.jsp", wherein I am populating the characters
dropdown as and when the TV Show dropdown value changes , by calling the
javascript in the “onchange()” of the select box.
have added a html link, and I want to call the same function from my action
class and I need to populate the character dropdown by clicking the html
link. I am stuck up with this issue.Character dropdown is not populated with
the data from tha action class. Need some help on this please!
<%@ page import="java.util.*"%>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>
<script language="javascript">
function retrieveURL(url) {
if (window.XMLHttpRequest) { // Non-IE browsers
req = new XMLHttpRequest();
req.onreadystatechange = processStateChange;
try {
req.open("GET", url, true);
} catch (e) {
alert(e);
}
req.send(null);
} else if (window.ActiveXObject) { // IE
req = new ActiveXObject("Microsoft.XMLHTTP");
if (req) {
req.onreadystatechange = processStateChange;
req.open("GET", url, true);
req.send();
}
}
}
function processStateChange() {
if (req.readyState == 4) { // Complete
if (req.status == 200) { // OK response
document.getElementById("characters").innerHTML = req.responseText;
} else {
alert("Problem: " + req.statusText);
}
}
}
</script>
<form action="ShowCharacters">
/jsp/tvshow.jsp Click here
TV Show:
<select name="TVShowSelect"
onChange="retrieveURL('ShowCharacters.do?tvShow=' + this.value);">
<option value="Lissie Maguire"> Lissie Maguire </option>

Unless you are using one of the IE plugins for web
development you are making things more difficult than
necessary. Test on Firefox with the Firebug plugin
then verify it works under IE.

What "returned data" are you talking about then?
It's not clear to me what "link" you're clicking; are
you talking about the <select...> tag onchange
handler?

Well, what debugging have you attempted? Are you running in Firefox with
Firebug for instance and seeing some client-side error? Have you verified
that your Action is getting called? Have you examined the returned data
to ensure it's correct?

You already have the code, you posted it! :) If you're having some

RE: Ajax Call from a html link
Posted by "Hodgins, Grant" <Gr...@SierraSystems.com>.
Not to detract at all from the great JWP project but you can also do
this with AjaxTags.
The ajax:select tag is described here:
http://ajaxtags.sourceforge.net/usage.html
I used ajax:select to call an action that returned XML using the handy
AjaxXmlBuilder that came with AjaxTags.
Cheers,
Grant

Just an FYI, that article is a little outdated... APT's feature set is a
bit larger than the article talks about now for one thing, although in
glancing over it again, I don't see anything that's not applicable now.
Also note that the link to Rick Reumann's article is no longer valid, it
is now here:
http://www.learntechnology.net/content/ajax/ajax_select_alter.jsp ...
Rick also updated that article for APT fairly recently, so it's even
better than it was.

chapters 4 and 6 there are what's of interest, although as the note in

are slightly different now.

Re: Ajax Call from a html link
Posted by "Frank W. Zammetti" <fz...@omnytex.com>.
Just an FYI, that article is a little outdated... APT's feature set is a
bit larger than the article talks about now for one thing, although in
glancing over it again, I don't see anything that's not applicable now.
Also note that the link to Rick Reumann's article is no longer valid, it
is now here:
http://www.learntechnology.net/content/ajax/ajax_select_alter.jsp ... Rick
also updated that article for APT fairly recently, so it's even better
than it was.
Lastly, I didn't provide a link to my own book in that article! D'oh!

Re: Ajax Call from a html link
Posted by Ted Husted <hu...@apache.org>.
I believe this exact example is included with the AjaxParts Taglib,
which works well with Struts (1 or 2). If anyone is going to be using
Ajax and JSP tags together, AjaxParts is a great way to go (and easy
to learn!).
