海外TECH	DEV Community	Super Simple Select Implementation Using Angular CDK Selection Model	https://dev.to/angular/super-simple-select-implementation-using-angular-cdk-selection-model-52gb	Super Simple Select Implementation Using Angular CDK Selection ModelBuilding out Selection feature for tables list can be challenging at times because of a lot of corner case that needs to be handled Here s how we can build one without writing much logic using the Angular CDK s SelectionModel utility Angular CDK SelectionModelAngular CDK comes with a lot of utilities and components that we can use to build our application One such very useful utility is the SelectionModel utility that is part of the Collections utilities in Angular Material CDK SelectionModel is a utility for powering the selection of one or more options from a list This model is used in components such as the selection list table selections and chip lists Understanding the API ️The Selection Model class comes with a lot of handy methods that make it super easy to maintain the state of selections Here s how we can use it const selectionModel new SelectionMode lt string gt The class constructor takes in these arguments multiple whether we can select multiple items at a time multi select initiallySelectedValues initial selectionemitChanges Whether to emit changes selectionModel changed property compareWith A method that can hold the logic for identifying if an item is selected Usage with all the arguments provided export interface Movie id number name string year string const selectionModel new SelectionModel lt Movie gt true lt multi select lt Initial selections true lt emit an event on selection change otherValue value gt otherValue id value id lt compare method which checks the id of the movie We can provide a custom compareWith method to get if a checkbox is selected selectionModel isSelected method Here s how it s used internally isSelected value T boolean if this compareWith for const otherValue of this selection this selection is a Set if this compareWith otherValue value return true return false return this selection has value Building a Table with Selection ️Now let s use the selection model to build a table with ability to select a row and also have a global checkbox to Select All Deselect All lt section gt lt table gt lt thead gt lt tr gt lt th gt lt input type checkbox checked selectionModel selected length gt indeterminate selectionModel selected length gt amp amp selectionModel selected length lt tableData length change onCheckAllChange event gt lt th gt lt th gt Name lt th gt lt th gt Year lt th gt lt th gt Rating lt th gt lt tr gt lt thead gt lt tbody gt lt tr ngFor let row of tableData gt lt td gt lt input type checkbox checked selectionModel isSelected row id change onCheckRowChange row gt lt td gt lt td gt row name lt td gt lt td gt row year date short lt td gt lt td gt row rating number lt td gt lt tr gt lt tbody gt lt table gt lt footer gt lt button type button click toggleSelectAll gt isAllSelected Deselect All Select All lt button gt lt footer gt lt section gt Component selector sreyaj exp cdk selection template lt see code above gt standalone true changeDetection ChangeDetectionStrategy OnPush imports NgForOf DatePipe DecimalPipe export class CdkSelectionComponent readonly tableData MockData readonly selectionModel SelectionModel lt number

selectionModel toggle row id public toggleSelectAll void if this isAllSelected this deselectAll else this selectAll private selectAll void this selectionModel select this tableData map row gt row id private deselectAll void this selectionModel clear Here I ve used the id property to maintain the selection state but we can use the full data also for the selection All selection and indeterminate state The way we check for all selection intermediate state is lt input type checkbox checked this selectionModel selected length gt indeterminate this selectionModel selected length gt amp amp this selectionModel selected length lt this tableData length change this onCheckAllChange event gt We mark checked by checking if at least one item is selected by looking at the length of the selected items checked this selectionModel selected length gt Next we set the indeterminate state by checking if at least one is selected but not all indeterminate this selectionModel selected length gt amp amp this selectionModel selected length lt this tableData length Selection change event ️We can configure if the selection model should emit an event on change or not This is specified using the emitChange argument in the constructor Here s what the event looks like export interface SelectionChange lt T gt source SelectionModel lt T gt added T removed T selectionMode changed subscribe change SelectionChange gt console log change We ll be able to get the list of items added and removed and the model itself in case we want to do more when the selection changes The good thing about the selection model is that it s not coupled to any component it s completely headless It can be used with lists and other similar components A small but really good utility that allows us to concentrate on the actual business logic instead of things like this Code and Demo TitleLinkSource CodeDemoAngular CDK SelectionModel Docs selectionmodelAngular CDK SelectionModel Code Connect with
