How to realize form single selection and multiple selection deletion by Angular6

background api is deleted through id, but it is stuck here. I don"t know how to judge whether it is selected or not.

Angular6 node.js typescript

check a field of control binding data such as selected , and control binding such as [(ngModel)] = "xxx.selected"

filter the selected id array before deleting

xxxList.filter((item) => item.selected == true).map((item) => item.id)

Previous: Mini Program's acquisition of formId,submit event is interrupted by binding event

Next: Input type= "file" needs to be checked on the interface before the file is uploaded, and the file box can be opened only when the check is passed, otherwise a prompt is given.
