Dynamic repeater with Flex 4 - actionscript-3

I have the problem and not find the solution on Internet. I am using the repeater control the use add the check boxes. First time i have the array length 10 and i bind this array to repeater and also use the label property of check box to bind the label. First time it work fine but the second time i change the array length from 10 to 5. I passed this array to repeater data provider but it through the exception of Null. I didn't recreate the component but only change the array length on button click event.

How to assign a dynamic value to input List property in angular

I want to render multiple dropdowns in angular based on the result from api.
From the api 2 dropdown controls are returned with different data however my code shows same data for both of the controls
Can anyone suggest how to assign a dynamic value to the property "list" in the input element?. I think if that is possible my problem would be solved or please let me know if there is any other solution
As list is an input attribute not a property, you can assign dynamic value to list using:
[attr.list] ='object.property'.

Can't set step property in input type number iside alert

I have an input type number inside an Ionic v4 alert, the problem is that I can't set step property since It's not recognised, is there any workaround or solution?
If you have advanced alert needs you might consider making a modal form instead.
The alert doesn't have many configuration options.
I don't see the value in trying to recreate a full modal tutorial here. This seems to cover it quite well.
But the high level overview is that instead of using an alert you create what is basically a new page, but it is loaded in on top of the existing page and you can pass data in and out of it.

How to handle forms with variable number of inputs with node js

I have a form on my page where one of the items input is a list of services available, and there are buttons to add and remove inputs for more or fewer services (i.e. enter first service click add service button and another service input spot appears, click remove service button and the last service input spot is removed)
Now I need a way to handle that input information on the back end using node.js and express of course without knowing ahead of time how many services are entered. I've read in other places about posting to an array but I don't know how that works with node.js/express.
Get all the fields that can be added /removed via an array of values in the html form. On the server side, the array with be available under req.body.
Note - You will need body parser or something similar to get hold of the form inputs.
Also, if you are using ajax, serialize the form inputs before posting the form.
So for that would I just make the name properties of the inputs things like "service[0]" and "service[1]" and so on?

Removing items on click based on checkbox status using angularjs

I am using this Plunkr. It displays a list of products. When I click on remove button, the items which are checked should be removed from the list.
<button ng-click="onClick()" class="k-button">Remove</button>
I have tried various things however, nothing is working. I am not exactly getting what logic should go in the following logic
$scope.onClick = function () {
}
I know it is something very simple however, I am not able to get it. Any help would be appreciated.
If you ask about logic, i will try to explain it here..
First inside onClick function get your gird's datasource variable, then find all selected checkboxes and use jquery each to iterate over each checkbox and find closest data-uid attribute. Every grid row has uid in its DOM, with this uid value get kendo observable object from datasource with getByUid method.
Last using datasource pass this observable object to remove method of datasource.
This is Kendo datasource API, hopes it helps you to write the code..

AS3 Datagrid multiple selection

I am working with Flash AS3 (not Flex) .
I have a datagrid with "allowMultipleSelection = true";
I want get and store the selected rows in my Data Base only when the row selection is completed using a button. (I don't want use "ListEvent.ITEM_CLICK" because a row can be selected and removed from the selection using the CTRL key)
How can I retrieve the selected rows in the datagrid?
Assuming you are using fl.controls.DataGrid, you can use the selectedItems property (it's an Array) to get (or set) the selected items when your button is clicked.
I had a datagrid which had checkboxes which use to get checked when a datagrid row was clicked. I wanted to allow multiple selections and also make the corresponding rows as checked or unchecked depending whether they are selected using shift key. I was able to do so by using the contains method of arraycollection and then checking the checkbox.
