Struts2 : Calling AJAX function on button click and passing form parameters to the same
Hi All,
I am new to Struts 2, so please forgive me if this question is inane.
I have a very simple form which has some checkboxes and on the click of
the submit button of the form, I want to pass the values of the form to
an AJAX action.

<script type="text/javascript">
function getResult(){
//document.getElementById("diaryRecords").setAttribute("href",
"/equipment.showHistory.action?serialNumber="+serialNumber);
//alert('In Get result');
buildValue = document.myForm.build.value;
//alert('buildValue : '+buildValue);
//dojo.event.topic.publish('/example/result.action',
buildValue);
document.myForm.hiddenbuild.value=buildValue;
//alert('document.myForm.hiddenbuild.value :

loadingText="Loading Result..." listenTopics="/example/result.action"
href="%{ajaxResultUrl}" />
</td>

Now, I have two problems in this:
1. I am unable to pass the form parameters to the action. As you can see
that the form submits to homepage.action, but I want the AJAX call to
load from result.action. I have passed the formId to the div, but it
doesn't get the form parameters in the request. To work around this, I
am passing the value of build (build is a checkbox) as a param and
referencing the URL on the div as href.
2. The problem with pass as href : The result.action executes on page
load, I want it to execute on the submit button click and then display
the result.
Ideally, when I click submit, I want these form elements to be submitted
to result.action and the result will be displayed.
The code snippet above submits the build value as 'on' to the form and
the result is displayed on page load.
Please help, I wasn't able to get any good code examples doing this, it
would help immensely if I could get that.
Thanks for reading,
Regards,
Sayali.

Posted by "Kanade, Sayali" <Sa...@gs.com>.
Thanks for all your help!
I tried changing the href of the div on button click but that doesn't
work. How I finally managed to do this was by passing a hidden form
field to action. The action only executes when the form field has a set
value. So on page load the Action doesn't get this value and the div jsp
doesn't get it and displays nothing.
What I was doing wrong was that my Form had a name parameter, the form
must have an id parameter to pass form fields. Also, my Action class
also behaves like a form bean, it needs to have a getter and setter for
the form fields.
As I said, new to Struts 2 and got all confused.
Thanks again,
Regards,
Sayali.

You could tryusing a Javascript function to set your div to
"display:none" on
page load and re-set it when you want to display it.

Hi
on thing i noticed is that you have a notifyTopics attribute on you submit
tag which i dont think is necessary and used wrong.
i havent used dojo for a long time, so i am not sure if they changed any api
or settings.
but just a reminder you might need to take a look.
you dont have to specify href on your div.
you can change it or assign a href in your onclick function like
dojo.byId("resultDiv").href = "/example/result.action";
see if this help

Hi,
Still stuck here, can anyone please provide examples of populating a div by calling an action after page load on button click??
Is this supposed to be this hard?? :(
Any help would be appreciated.
Thanks!

Sayali.

Thanks for your reply, but not sure it answers my question.
My question is: How can I prevent a div from refreshing its contents on page load? The div should only be refreshed on button click.
My problem is that, my div loads on page load. It also reloads on submit button click, but it should ONLY load on submit click, not on page load.
The action that executes in my div has to be only executed after the user selects a checkbox and clicks submit.

Hi,
I don't' know if I get the idea about what do u want to do, but I will try
to copy some codes about how I resolve something similar, using AjaxTags
<ajax:htmlContent target="tabContent" source="sendAfs" doPost="true"
baseUrl="${pageContext.request.contextPath}/relatie/tabAfspraken.do"
parameters="id=${rsKlantId},action=saveAfs,${paramsForm}" />
in this case the id for my button is sendAfs and is sending my post
everything that is in the form. In my case is really a lot of fields and is
difficult to copy one by one, then for me was better to create a form that
will get all the fields:
Fields:
public String filterArtikelNr;
public String filterArtikel;
public String filterSoort;
public String filterMerk;
public String filterType;
public String filterVervallen;
Function for get an string with the parameters list in the form:
paramaterName = {paramaterName}
This is the way for write the fields in Ajax
public String getParams(){
StringBuilder sb = new StringBuilder();
Field[] f = this.getClass().getFields();
for (Field field : f) {
sb.append(field.getName() + "={" + field.getName() +
"},");
}
return sb.toString();
}

Thanks for your reply, but not sure it answers my question.
My question is: How can I prevent a div from refreshing its contents on page load? The div should only be refreshed on button click.
My problem is that, my div loads on page load. It also reloads on submit button click, but it should ONLY load on submit click, not on page load.
The action that executes in my div has to be only executed after the user selects a checkbox and clicks submit.

Now, I have two problems in this:
1. I am unable to pass the form parameters to the action. As you can see
that the form submits to homepage.action, but I want the AJAX call to
load from result.action. I have passed the formId to the div, but it
doesn't get the form parameters in the request. To work around this, I
am passing the value of build (build is a checkbox) as a param and
referencing the URL on the div as href.
2. The problem with pass as href : The result.action executes on page
load, I want it to execute on the submit button click and then display
the result.
Ideally, when I click submit, I want these form elements to be submitted
to result.action and the result will be displayed.
The code snippet above submits the build value as 'on' to the form and
the result is displayed on page load.
Please help, I wasn't able to get any good code examples doing this, it
would help immensely if I could get that.
Thanks for reading,
Regards,
Sayali.
