When a user clicks on a page, then an evry time xml file should be loaded dynamically.
You may try to use the setXMLAutlLoading() method. Its second attribute (buffer) defines the number of rows coming from the server at a time

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 a performance issue when I open ionic 3 Modal.
I need to show a list in the modal and the length of list is 1000.
It takes few seconds to open the modal while they are rendered.
I thought about using InfiniteScroll in the modal, But I use Searchbarwhich means server-side should develop more APIs for that.
Since the data of list is quite static, I would like to make like :
Preload the modal page and hide by default.
Show the modal when it should be opened.
When the modal is closed, DO NOT destroy it, just hide.
But according to the ionic docs, I can't reuse modal.
So my question is : Is there a better way to make searchable 1000 list in ionic3?
Thanks.
EDIT : I have tried with localStorage to save json (about 100kb) and stop using XHR to reduce loading time. However I don't feel loading time gotten faster. I tested with just 100 list instead of 1000 and opening modal was a lot faster.
There are a several options:
If it is actually static, just place it in web storage and retrieve it when the use reloads the page.
If it's "quite" static, whatever that means, just place it in the DOM somewhere so it only has to load once per page load. When the user clicks the link to open the modal, store the data in a hidden field. It might even be a good idea to load it asynchronously as the page is loading, which could potentially completely eliminate any loading times at all from the user's perspective.
Use your own modal, and just hide/show it. Load it async.
Example of cache
jQuery AJAX Example
Ok I made it by using <ion-infinite-scroll (ionInfinite)="doInfinite($event)">.
First of all, when modal is opened, get list data from the server
and save in local storage
In the beginning just show 20 items out of 1000. So the rendering
would be a lot faster.
When user scrolls down, doInfinite will be executed.
In the doInfinite function, check what is the next index in order to show
the data. Like pagination logic. And get proper data and push to
the list array.
About <ion-searchbar>, when you get list data from either server
or local storage, save an original list data for the search (In my case, I just used this.originalData = myData like that.). By doing so, whenever user searches by typing, you can filter from 1000 array but no slow rendering issue.
I have a problem regarding modal popup and session.
I have two component name test and test1 respectively.
In test there is a form in view in which i put "Anchor" tag with "modal" class. has also class name "class1".
When i clicked on Anchor tag it call click function(on click "class1") in which i put ajax code for set data using "Session".
$('.test').click(function(){
// Ajax code here for set data using session
});
with above function it also called modal popup. here targer url is seted which is the view of 2nd component which is "test1".
Here in test1 there is a view.html , we are getting session data here and displaying in view.
PROBLEM
Problem is that , here in 2nd component , in view i am getting session data but i need to click on button two time , only after i getting data properly.
When i click on it give me a old session data. and when i click on it second time it will give me a proper data.
What is the solution for above problem. if anyone know please let me know.
Session data is altered only after we click on Anchor tag.
Both thing is done on Anchor click , one is for set data in session and second is for modal popup. in popup i am getting data which set in session.
when is the session data is being altered?
Is it altered by ajax call too?
In this case, javascript, is unsynchronous. It doesn't wait for something to happen in order to fire the next line of code. In that case there are several techniques you may find to do so.
I'm trying to find a way to get the page number of a specific record.
This is my problem, after I add a new line I reload the grid, with sorting on, the new line can end up on any page. I need to be able to find the page number of that specific record, so I can navigate to its page and select it.
How can I do that, without having to load every page until I find it.
As I see to to accomplish where you would add a new record, reload the grid and then have that displayed page be the page where the new record would be found in a sorted grid. As a solution I think you would need to set the reloadAfterSubmit: false, and then generate your own reload where you would pass in (via postData) a value that would tell your controller to change the page of data to return to the jqGrid.
When the controller would receive a value in this field you would have to write some code to find which page of data the record would belong to and then pass that page to the jqGrid.
As the grid would be sorted, you could find where where that record would be in the sorted dataset and then grab that page. If you didn't have a very large dataset you could just iterate through every page till you found the page that would contain your result, but the method would depend on how large of dataset you would have. (Ex 5 pages of records, probably acceptable to just iterate through them all, as the dataset becomes larger you will have to look into fetching the proper page of data.)
I have one view page in MVC named as ‘Index’. There are 3 main controls in that view page. For better understanding, take below example as reference.
1. One Dropdown ‘Customer’
2. One Dropdown ‘Project’ (that depends on ‘Customer’)
3. List of Task (that depends on ‘Project’).
Currently first user needs to select ‘Customer’. So based on customer ‘Project’ dropdown data will be fetched from post method of Index and bind that ‘Project’ dropdown. After selecting ‘Project’, List of task will be fetch from post method of Index and bind those tasks. So every time page is loaded again.I want to do it by Ajax form submit.
My problem – those 3 controls are in one view page so I want to return page view using Ajax without using Partial View. Is this possible? If yes then how? Or any other solution so that I am able to display data without reload whole page again.
If u can give me example of such scenario then it will be good.
