Is there any function or ng-something to check if any of the displayed Checkboxes are checked?
I have the values through the ng-click="function()" and pass the values through. I can go by foot and check my array if any value is inside.
I want to activate/deactivate the "next"-button if any Checkbox is checked.
What's the easiest way?

The ng-checked Directive in AngularJS is used to read the checked or unchecked state of the checkbox or radio button to true or false. If the expression inside the ng-checked attribute returns true then the checkbox/radio button will be checked otherwise it will be unchecked.
To check if a checkbox element is checked in TypeScript: Type the element as HTMLInputElement using a type assertion. Use the checked property to see if the element is checked. The property will return true if it is checked and false otherwise.
Use the following steps to get checked checkbox values in angular 13 apps: First of all, open your terminal and execute the following command on it to install angular app: In this step, visit src/app directory and open app.module.ts file. Then add the following code into it:
Just define an ng-model directive in the checkbox and to find checkbox checked or not check model return value (TRUE or FALSE). If it has TRUE means checkbox is been checked.
There are many ways to know weather a check box is checked or not you can use Reactive Form Control OR Template Driven Forms etc. But In your case I think you just want to check the checked property of a single checkbox then the easy way of doing that is to use template variable and access that in your ts file using View Child.
If you need to add one master checkbox on top and when you check that checkbox then bellow checkbox list check checked all and unchecked all. so same feature i will give you instruction how can be done this thing step by step. you can easily use with angular 6, angular 7, angular 8 and angular 9 app.
If you don't want to use a watcher, you can do something like this:
<input type='checkbox' ng-init='checkStatus=false' ng-model='checkStatus' ng-click='doIfChecked(checkStatus)'> If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
