Display content of database in a form with textfields in struts2.
Here is a senario. It's just an example.There is a jsp page (abc.jsp) which shows list of employees. This page contains a button (Add employee), when user clicks this button an action abcAction is called which opens xyz.jsp asking user to fill necessary information like emp_ID, emp_name, etc. On sucess abc.jsp page is opened showing the entered information on a table. Along with this informtaion an"edit" button is appeared on the same page(abc.jsp). Now how to display xyz.jsp page when user cicks edit button along with the necessary fields entered by the user based on emp_ID.

I want to use ASP.NET MVC to create a registration page.
The registration page will have a single view and it will have multiple forms. The user can use "back" and "continue" buttons to go to a form (partial form).
First step:
On Form1, the user will enter his name, email and click "continue" which should do a postback and validate the form inputs. If form is valid, display form 2.
Second Step:
The user will add his company address and then click on "Done".
How can I create such a form in multiple steps?

I have a Submit page that has severial checkboxes that are been built dynamically as soon as the page load. The user can check one or more checkbox before submitting the form. On the right hand side of the page, there is somewhat a summary of all the previous selections that the user chose. The summary is available from the Submit page and will carry to the other pages. There is an "Add Comment" button at the very top of the page. When the user click it, a popup window with a textbox will display allowing the user to type a comment. How do I display this comment on the page without having a refresh the page?
The main reason for not wanting to do a refresh is because the user could have selected one or more checkboxes, they will lose their states as soon as the page is refreshed.
I tried parent.document.getElementById('DivCommentResult').html(data); - It displayed this message "Microsoft JScript runtime error: Unable to get value of the property 'html': object is null or undefined"
If I understand well, you have to bind the change of your check box to a function that submit a synchone ajax request that obtain the summary you need and replace target content with the result data of your request.
Is it what you want ?
I had to get the parent doucment and retrieve the div id from it.
Once I have it in hand, I set its innerHTML text to the data that I want to display.
var parentDocument = parent.document;
var el = parentDocument.getElementById('commentResult');
Once I have this, I simpley call el.innerHTML = data;
Questions on Rails 3.0.7, and JQuery 1.5.1
Overview
I'm trying to do the following thing. I have a web page with a form on one side that lets me create a category, and a list of items on the other side, with a checkbox for each item. I would like to be able to check the check box, for each item, so that when I submit the form to create the category, the newly created category also creates a has_many through association with each item.
So the association part works almost, I can submit a list of checked checkboxes, and Rails creates the association on the backend if I send the list of checked items.
Problem:
Here's what doesn't work:
I am trying to submit the form via Ajax, so I wanted to bind an event handle to the rails.js 'ajax:beforeSend' event, so that it would scan through my list of checked checkboxes and at the checked ids to a hidden form field.
The problem is: I try to get a list of all the checked boxes, and add them to the hidden field when the user clicks the Submit button. Therefore, I figured I'd place the code to do so in the ajax:beforeSend event handler. What I "THINK" I'm noticing however, is that rails.js has somehow already processed the form fields, and constructed the HTTP query before this handler fires. I notice this through the following behavior:
Observed Behavior
1) I can reload a fresh page, click the button to submit the form, the alert boxes from my handler pop up saying that no boxes are checked, and the created category in my db has no associated items (CORRECT BEHAVIOR)
2) I then click 1 checkbox, the alert boxes pop up showing which boxes are checked (CORRECT). But then when I submit thee form, the category in the DB still has no associate items. And I can see through firebug and the server logs that and HTTP query was sent containing the old parameter list, not the newer one. (WRONG)
3) I then submit the same form again, changing nothing, and it shows me the correct number of items.
So I get the impression that the parameter construction is lagging. I hope this wasn't too long, an someone can help me figure out what is going on.
My Question:
What event do I need to bind to, so that the form gets submitted with the correct parameters? Or is there another way to go about it completely?
Thanks
Here's my code below.
Thanks,
$('#my_form')
/* Now we need to configure the checkboxes to create an association between
* the items, and the interaction that is being created. First we will bind a
* function to the click event, and if the box is then checked, we will add
* the item id to the list of interaction items. If it is unchecked, we will
* remove the item from the list of interaction items.
*/
.live('ajax:beforeSend', function(event){
// First get a list of all the checked Items
var checked_items = new Array();
$('#items input[type="checkbox"]:checked').each(function(){
checked_items.push(this.getAttribute('data-item-id'));
});
// Then add this list of items to the new_interaction form to be submitted
$('#interaction_new_items').val(checked_items);
alert(checked_items);
alert($('#interaction_new_items').val());
})
Bind to the click event on the submit button itself. The click event will be processed before your ajax beforeSend event.
$('#my_form .submit').click(function() {
// rest of your code here
});
A more flexible solution (say, in case you wanted to submit the form with something other than a click) would be to bind to the form's submit event.
$('#my_form').submit(function() {
// Tweak your form data here
})
I've got a page that creates a ticket in our help desk system. It acts as a wizard with the following steps:
Step 1
User selects the customer from a dropdown list. There is a jquery onchange event that fires and generates the list for step 2 and hides the step1 div and shows the step2 div.
Step 2
User selects the location from a dropdown list. This is generated based on the customer selected in step 1. There is a jquery onchange event that fires and generates the list for step 3 and hides the step2 div and shows the step3 div.
Step 3
User selects the type from a dropdown list and enters text into 3 different text boxes. If the user fails to enter text or enters invalid text my controller changes the model state to invalid and returns the view.
How can I get all the dropdowns to repopulate again with the correct selection the user chose and get the page to redisplay on Step 3?
My first thought was to use ajax and when the user clicks the Create button, I could create the ticket from there and if successful send them to the ticket detail. If unsuccessful, well just display an error message and i'm still on the page so no big deal. Now that I write it out I think this is best. Are there any major issues using ajax? It seems most sites use some type of javascript or ajax these days.
Second thought is to not use ajax at all and submit all the pages to the server.
What do you suggest?
The 3 steps display completely different markup.
There is possibly not much you can gain by an AJAX-version, except the avoided page flicker when you change the steps.
If you go the non-AJAX way you gain:
nice bookmarkable links ( www.ticketsystem.com/Customer -> www.ticketsystem.com/Customer/Microsoft/ -> www.ticketsystem.com/Customer/Microsoft/Location -> www.ticketsystem.com/Customer/Microsoft/Location/Redmond )
browser history works
easier testing
To redisplay the lists after step 3 you would load all of them and set the selected item according to the parameter in the URL.
I agree with you. Use AJAX to submit the ticket.
