In knockout Change Paging when Data is changed



In knockout I wish to change/ refresh Paging when data is changed.
For example: I have a data set of 100[5 Records per Page] and I am on Page 10. Now with some more search Data is changed from 100 to 5 and I am on Page 10, but when data is changed I want paging to be on First page. i.e Paging to be refreshed.



Here is my [Fiddle] (https://jsfiddle.net/975ncawv/281/)


MyVM.prototype.loadData = function(rawData)
this.items(rawData.map(RowModel.fromRawDataPoint));
;
ko.applyBindings(new MyVM(myData));

Two things need to be changed inside the loadData function.


loadData


all


items


pageNumber


paginated


all


paginated



It would look like this updated fiddle.



but when data is changed


this.items.subscribe( /* ... */ )



I want paging to be on First page


this.pageNumber(0)



Put together:


this.items.subscribe(function()
this.pageNumber(0);
, this);



I don't see any logic concerning the search data, but I'd expect something along the lines of:


this.filteredItems = ko.pureComputed(function()
return this.items().filter(/* ... */);
, this);



Once implemented, you can change the subscribe to items to be on filteredItems to make sure you reset both when the data source changes as well as when the search query changes.


items


filteredItems

I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas...

But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right.

Store custom data using WC_Cart add_to_cart() method in Woocommerce 3

Clash Royale CLAN TAG #URR8PPP Store custom data using WC_Cart add_to_cart() method in Woocommerce 3 I am creating a membership site and totally created static pages for each Membership plans (have only 3 plans). However, I have added products for each plan and when I hit SELECT PLAN button I redirect to some custom form where I ask users range of info we are going to use to fulfil the plan (same as sneakertub.com). I have written code into the PHP page which will handle SUBMIT action of the form. This PHP file, infopage.php , will process POST data I sent via POST call and stores these all data into WC session. infopage.php $customer_name = $_POST["customer_name"]; $customer_email = $_POST["customer_email"]; $customer_sex = $_POST["customer_sex"]; $customer_age = $_POST["customer_age"]; $product_id = $_POST["product_id"]; global $wp_session; $data = array( 'customer_name' => $customer_name, 'customer_email' =...
