why Struts2 can't receive Jsp variable value by using Ajax1.2?
I have a text area and a text link in a jsp page,when I click this text
link,I will call struts2 action by using ajax,like follows:
/*-----jsp page-----*/
<html>
<script type="text/javascript">
var http = getHttpObject();
function getHttpObject(){
var xmlhttp = false;
if(window.XMLHttpRequest){
xmlhttp = new XMLHttpRequest();
if(xmlhttp.overrideMimeType){
xmlhttp.overrideMimeType('text/xml');
}
}
else{
try{
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
}
catch(e){
try{
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e){
xmlhttp = false;
}
}
}
return xmlhttp;
}
function handleHttpResponse(){
if(http.readyState == READY_STATE_COMPLETE){
if(http.status == 200){
var text = http.responseText;
if(text != null || text.length >0)
alert(text);
}
else{
alert("error!!!");
alert(http.status);
}
}
}
function test(){
var t1=document.forms[0].abc.value;
alert(t1);
var url = "add.action";
http.open("POST",url,false);
http.onreadystatechange = handleHttpResponse;
http.send(null);
}
</script>
<body>
<s:form action='add.action' method='post'>
<table>
<tr><td><s:textfield label="test1" name="abc"/></td></tr>
</table>
<a href="javascript:test()">tt</a>
</s:form>
</body>
</html>
/*----struts2 action----*/
public class TestAction extends ActionSupport{
String abc;
public String add() throws Exception {
System.out.println("abc="+abc);
return null;
}
public String getAbc(){
return abc;
}
public void setAbc(String abc){
this.abc=abc;
}
}
I put some text in textfield and then I click tt link,it call struts2
action,it execute System.out.println("abc="+abc),it should show the text
value,but it shows null value!!!
abc=null
If I don't use ajax,and only use document.forms[0].submit(),struts2 can show
right value,like follows:
abc=the text you put
I am puzzled with it! Why struts2 can't get jsp page value by using ajax?
Anybody could tell me how to correct my above code?
Thanks in advance!

I fully intend to jump in... but jump in to JWP, not S2. Lots of items
on the to-do list there that need to get done. I also need to *finally*
get the next version of DataVision out the door, that's been far too
long in coming. I'd like to contribute to S2, but I'm not at all sure
what I have to offer at this point.

Sounds cool. You can do most of that with APT today by the way (the
dojo widget part would have to be a custom handler though) without
having to use S2 (not that using S2 is a bad thing!). I suppose I
should feel some sense of validation that the basic idea I presented 2+
years ago for S1 now makes it, roughly, into S2 :)

Yes indeed! but with multiple targets, multiple sources, passing a form,
with a form filter, instantiating Dojo widgets on the returned text and
topics. The code for the bind tag is already in S2, it just doesn't have a
tag yet.

Dave is right. On top of that, S2 ships with Dojo, so you can just do:
dojo.io.bind({
url: "add.action",
formNode: dojo.byId("form1"),
load: function(type, data, evt){
//callback called after request is made
},
});
We will soon have a "eventbind" tag that will attach to any element, on any
event, and will be able to make requests, populate targets, etc, etc, to
cover this basic scenarios.

I'll admit I've never bothered doing Ajax quite this
manually before, but you're not submitting the form,
but doesn't this just make a post request to the URL?
Try something like:
var url = "add.action?abc=" + t1;
http.open("GET",url,false);
I would, however, *strongly* urge you to use any
number of *way*-easier ways to do Ajax, especially
considering that S2 ships w/ lots of Ajax support.
