I have to regions with items on my page. One of them is to edit data, another one is display only. Editable region is hidden on page load and shows when users click on a button. I'd like to pass data between these regions after submit a page. Are computations after submit the only way to do that? I tried with processes after submit, before header etc. but it didn't work.
I'd like to have one pl/sql code to pass data between two regions after submit, how to do such a thing?
Other options include
dynamic action (you'd use Set value)
button's Redirect to page in this application (where you'd redirect to the same page; Link Builder then lets you choose which items will be set to which values)
If you still can't make it work, consider creating sample page on apex.oracle.com; then provide login credentials so that someone might have a look.

I have created a page in oracle apex where I have multiple regions and each region has a Submit page button.
Each submit has an ajax callback associated with it.
Will clicking on any one submit, also execute the other ajax callbacks?
In other words, when we click a Submit page button in one region, is it exclusive only to that regions ajax callback or will it execute all ajax callbacks of that page?
Button name determines value of the REQUEST attribute. If you look at the process values, you can set the "Editable Region" (which shows which region is associated with this process), as well as the request itself (under the "Server-side condition" properties; see the "When button pressed" and "Type").
So, if you create your own process which does something and set properties described above, each SUBMIT button should affect only its own region.
Unless I'm wrong, if there's only one SUBMIT button (created with its default settings) on the page, it'll affect all regions.
I'm trying to make an apex form that has multiple 'pages' within it, so that I can achieve a nice layout.
For example:
Page 1 - Personal Details >> Page 2 - Occupation >> Page 3 - Career History >> Submit
Is there a way to do this without submitting one page at a time as this would mess up my validation for the table entry.
It's kind of a broad question - lots of possible solutions. You will need to create several regions on the page, so that you can easily show or hide different sets of page items without submitting the page.
If you simply want to keep the page tidy, you could make use of the Hide and Show Region template, or you could create a Region Display Selector region.
To help the user experience flow a bit better, I would probably do something like this:
Set up the page items using the Form wizard.
Create three HTML regions - Personal Details, Occupation, and Career History.
Move the page items into the appropriate regions.
Delete the original region created by the wizard, together with the default buttons.
Create navigation buttons in each region - probably a Next button in Personal Details, Next and Previous buttons in Occupation, and Previous and Submit in Career History.
Create dynamic actions for each of the buttons. The Submit button submits the page of course. The Next and Previous buttons show and hide the regions as appropriate.
I am converting an old web application. In the legacy version, there is a page which displays some default content when the user navigates to it. There is a link within that page which reloads the page but with a querystring showform=yes which causes a form to be displayed instead of the content.
In the old version, the page was like this:
http://site.com/directory.asp - for the main page with the content
http://site.com/directory.asp?showform=yes - called when the user
clicked the button to show the form.
In the new version of the web app, that same page is set up with ajax, in that there is a div which contains the default content when someone visits http://site.com/directory. There is a button, which, when clicked (from within that page), some ajax is invoked which swaps out the content and displays the form. There is no change in the URI/querystring.
Here is my question - In the legacy version of the web app, there are some other pages which link the user directly to the page with the form (http://site.com/directory.asp?showform=yes) e.g. so they don't need to click the button once the arrive at directory.asp.
Is there a what I can mimimc this behavior based on how I have that page set up now e.g. displaying the form via ajax in a div?)
Initially I thought that perhaps ajax can be triggered based on the presence of a querystring or an anchor in the URI e.g. /directory#form but I am not sure if that is possible.
I would prefer a solution that is not dependent on jQuery, but will consider it if there are no other options.
Thanks in advance for looking, and please let me know if I can further clarify.
Thanks,
Gary
yes you can trigger AJAX call on the basis of a boolean variable which you can set through the query string.
The default value for the boolean variable is false which forces the user to click on the button to refresh the form section.
But when the comes back on the same page the query string will set the boolean variable to true whereby the javascript function containing the AJAX code is invoked from your JSP/ASP or HTML.
I have a bit of a unique challenge today. I have a client that wants to be able to search for multiple items based on inserts into a cfgrid. Suppose we have the following web form:
A Country selection dropdown
A State Selection dependent AJAX dropdown
A city Selection dependent AJAX dropdown
An ADD Button
----------------------------------------------------
A CFGRID that will populate a row with selections when the user clicks the add button
----------------------------------------------------
And finally, a CLEAR button, and a GO button on the bottom.
The resulting page will then query the database and get some statistics about the cities selected. So, suppose an individual picks USA > Arizona > Scottsdale and USA > Arizona > Flagstaff. The grid below the options will 'save' each selection and reset to their default options, waiting for a user to pick additional options or click on 'GO'.
The resulting page will then generate columns that list some statistics about the communities and highlight the 'best of' between each selected community.
Each time a user selects the ADD button (assuming three criteria are selected) I want the information to be added into a CFGRID that displays the options selected. Then, After the user selects at least one country/city/state option, have all of the data in the CFGRID get passed to another page that does a query from the data selected. In theory, the user could pick as many communities as they want, assuming they are willing to let the database sludge through enough data to get what they want and wait through a 'loading' screen to get it.
I'm having these challenges, in no particular order:
- I have an HTML grid that I must use per client spec (No Java or Flash, must be HTML)
- I have no idea how to get the selected options into the CFGRID. I assume there is some JavaScript I can write that uses some sort of AddRow function to add data into the grid with the add button but cannot seem to find how to it on the interwebs
- After we conquer the above challenge, how do I pass the data from the grid into the results page? I thought about passing one big string or a structure, but I'm not sure how to do that through the URL or posting, nor how to get the data out of the grid. I wonder if I am better off coding some sort of string that gets passed from the options page to the results page with a get method instead of dealing with the stuff in the CFGRID and have the CFGRID serve only as a 'dummy' display container.
- Finally, after the pass is complete, I would need to loop through through the structure and perform a CFQUERY or CFSTOREDPROC on each row of data, then get the statistics I need to display on the results page. I assume this would depend on how I am getting the data from the options selection page to the results page.
THANK YOU ALL!
CFGRID is great to start, but it can be b*tch to customize and extend... Have you tried editable CFGRID with bind? See how far off it is from what you want first. If it turns out to be very far, then you might want to go for a jqGrid and code up some jQuery.
To start, read Using HTML grids and make the cfgrid editable.

Once you got that working, look at these provided JS functions that you can use with CFGRID

If you still demand a bit more, you might need to dig into the underlying ExtJS component. At that point I would rather use jqGrid
I found out that the best way to handle this was by using a SerializeJSON call and a Deserialize JSON call back and forth. By using JavaScript notation we are able to pass a complex JavaScript object (array) between one page and another. This has the value add of not having to worry about sessions timing out and making URLs clickable from one solution to the next.
I'm using Joomla to develop a user profile management component with AJAX.
The goal is to allow the user to edit his own user information. There is a lot of information so instead of having one massive form, I decided to make "subforms" or sections. And for the whole thing to be user-friendly I want to send the forms and refresh the user information with AJAX.
Here's an example :
There are two sections, "Basic user info" which displays the first name, the last name and the age of the person and "Extended user info" which displays the occupation, the company and the skills of the person. Each section has an "edit" link (or button) which turns the content into a form (AJAX) allowing the user to modify the presented information. You can only edit one section's information at a time. When the user has finished modifying the data, he sends the form with a "send" link (or button) and the section gets back to simply displaying the information of the section (with the updates that were just made).
So I need to know what is the most efficient way to develop such a component. I thought of two approaches :
1) In the "tmpl" directory of the main component view we the following files :
default_basic.php (displays the basic user information),
default_basic_edit.php (displays the form which allows the user to edit the basic information)
default_extended.php (displays the extended user information),
default_extended_edit.php (displays the form which allows the user to edit the extended info)
default.php (loads each of the display subtemplates with calls to JView::loadTemplate($subtemplate))
When the user clicks on an edit link, an AJAX call is made to the following URI index.php?option=com_userinfo&view=userinfo&subview=basic_edit&format=ajax, which causes the view class to call $this->loadTemplate('basic_edit') after assigning the user information to it.
If the user clicks cancel the same process is used to load the 'basic' template again. And if the user modifies the information and clicks the send link, the form is sent and then the 'basic' template is loaded too.
2) There is only a "default.php" file in the "tmpl" directory which holds the edit version and the display version of each section. But all the edit versions are hidden at first. And when the user clicks on the edit link the display version of the section becomes hidden and the edit version is displayed (using display:none and display:block). Then, if the user clicks the cancel button we do the opposite. And if the user clicks the send button we send an AJAX request to update the data in the database and return the updated user info which will be loaded into the display version of the section. And we finally replace the edit version of the section with its display version.
I know there's a lot of text but in the end it goes down to choosing between refreshing full HTML blocks with AJAX, or just sending the updated info and modifying the content of hidden blocks and then make them appear. So what do you think is the most logical approach, knowing that we are in a Joomla 1.5 environment ? How would you procede ? (maybe there are other ways to create such a component ?)
(I tried both ways and I couldn't entirely make it work so I decided to ask to see if it is a matter of conception...)
Thank you for taking the time to read all the text.
My answer is: why even refresh parts when it can be done without it?
For example when we are talking about basic form elements like text fields and check/radio buttons I would prefer the following: on a successful save/send simply display a nice message like "Profile saved" for some seconds and the user is sure that the changes are save and sound.
In case I msissed somthing let me know.
I have tried both solutions and #2 is the only one that worked for me.
