原标题:Confused by Angular example on checked checkbox [closed]
Closed. This question needs debugging details. It is not currently accepting answers. Edit the question to include desired behavior, a specific problem or error, and the shortest code necessary to reproduce the problem. This will help others answer the question. Closed 8 hours ago. Improve this question On this page, there is example code and rendering of it. In particular, with the example code: Checked I was expecting the checkbox to be checked but on their page, it is blank. When using in my code it worked and checkbox is checked by default now. However, it crosses out ngModel as deprecated. Am I supposed to do this differently?
问题回答
In the example you shared, the property name is checked, the actual value comes from the angular signal readonly checked = model(false);, where false is the actual value that gets set on the checkbox, so its working fine. Signals are the new/better way to bind one-way, two-way properties, since change detection fires only when its absolutely necessary. TO learn more about model signals. Angular Docs - Two-way binding with signals As for the deprecated error, it s due to using formControl with ngModel together. To read more about the deprecation.
