I don't know for sure, but I think you would have to use a <s:form> tag, not
a <form> tag if you want all the automatic goodness to work.

RE: jquery + struts2 + form validation
Posted by adam pinder <ap...@hotmail.co.uk>.
all hidden fields will also be sent to the server using this method, but you could put those fields into a different form that isn't submitted and reference them with the form name within jquery if need be or accept them being sent - it probably will be ok performance wise as long as there isn't very high volumes.

Hi Adam,
You provided the info exactly what I need!
Thank you very much!
For users had same question:
http://api.jquery.com/serialize/
Only one concern: "var str = $("form").serialize();" in the online doc
will not cause any performance issue if lots of (hidden)tags in the
form, right?

RE: jquery + struts2 + form validation
Posted by adam pinder <ap...@hotmail.co.uk>.
jquery has built in ability to submit form elements in an ajax request
for example
$.post("AddUser_execute.action", $("#AddUserForm").serialize(), function(data){ cursor_clear(); $('#P4_AddUser').html(data); }, "html");
this statement will post to AddUser action and all form elements in the AddUserForm will be sent - the serialize method does the name/value pairing for you

It depends on the usage. We have search table default only several
fields shown. Users are allow to grab and display all hidden fields and
search based on those criteria.

An example:
==============================
<s:submit action="saveRecord" onclick="return checkRecord()">
Before real saving the the record into DB, check is done first.
The checking is against DB operation.
The jquery method checkRecord() has to say for example:
<script type="text/javascript">
function checkRecord()
{
//======================= from here ===============================
var checkbox_value = "";
for(var i=0; i < document.form.checkbox_value.length; i++)
{
if(document.form.checkbox_value[i].checked)
{
checkbox_value +=
"checkbox_value="+document.form.checkbox_value[i].value + "&";
}
}
if(checkbox_value != "")
{
checkbox_value = "?" + checkbox_value;
checkbox_value = checkbox_value.substring(0, checkbox_value.length
-1);
}
//======================= to here ===============================
var return_yn = false;
$.ajax({
async: false,
url : "check_oprAction.action" + checkbox_value,
success: function(data)
{
if(data==1)
{
return_yn = true;
}
else
{
$("#action_error_div").html(data);
$("#action_error_div").removeClass().addClass("errormsg");
return_yn = false;
}
}
});
setTimeout("timeExam()", 2000);
alert("return_yn = " + return_yn);
return return_yn;
}
</script>
Is there a way to escape "from here ~ to here". If the form can be
submit when calling ajax.url, I will not need to say:
check_oprAction.action?tag1=...&tag2=...&tag3=... ...tag300=.
See the problem I had is I do not want to do
"?tag1=...&tag2=...&tag3=... ...tag300=. " through javascript, but only
submit "check_oprAction"
This is just an example.
Thank you,

A form with hundreds of fields is a horrible mess anyway.

... By submitting the form? You're going to have to be more specific
in your requirements--I don't know what you mean by "can the form
values be submit[ted] automatically"--that's what a form submission
does, submits all the input elements in a form.

jquery + struts2 + form validation
Posted by Emi Lu <em...@encs.concordia.ca>.
Good morning,
A question about struts2 + jquery form validation:
in jsp:
=========
<form>
... ... lots of tags
<s:submit action1 onclick="return check_action()">
<s:submit action2>
<s:submit action3>
</form>
If check_action returns false, action1 will never be called!
JAVA action
================
private InputStream inputStream;
check_action()
{
check tag1 against DB; //whether dup, wrong info etc
check tag2 against DB;
... ...
PrintWriter out = res.getWriter();
res.setContentType("text/html");
if(error)
{
out.println("<li>Error info</li>");
...
}
else
{
out.println(1);
}
out.flush();
return SUCCESS;
}
The part gives me headache is that how to submit hundreds of tags in the
form in JSP?
I do not want to use action?tag1=..&tag2=.. ... tag300=....
Is there a way, form values can be submit automatically?
Thanks a lot!

Thanks for your response, the problem is that I don't know all the
parameters set in the Action... So I would like to retrieve the list of all
the request parameters as name / value list.
(sorry for my english but it's not my natural tongue)

What type of parameters? Request parameters? Via the request or a
ParametersAware (or whatever that's called, the one with the map)
action.
