问题 See this plunkr: https://plnkr.co/edit/nGKAnXrrzgKSxpkdvEhX?p=preview I have a simple <form> in Angular that displays a <input type="number"> field. When I enter something like "123" everything is ok. But the input "123-456" seems to be ok, too, although this is not a "real" number. I found out that Angular sets the myNumber.value to null and so everything seems to be ok. What I want to achieve is that Angular doesn't reset the input "123-456" to null and instead tells me that the input is

问题 In my project I am meeting several times the same problem, and yet, I have not been able to find a proper solution. I suspect it is all part of this issue, but it sounds to me like a very normal use case. Many times I have a component with a template such as: <my-component><ng-content></ng-content></my-component> where somewhere in the projected content is trying to get the instance of <my-component> . This simply does not work because the projected component gets resolved before <my

问题 In this article Todd Motto explains that: ngModel = if no binding or value is assigned, ngModel will look for a name attribute and assign that value as a new Object key to the global ngForm Object: <form novalidate #f="ngForm"> ... <input type="text" placeholder="Your full name" ngModel> ... </form> And about "banana" wrapping: [(ngModel)] = two-way binding syntax, can set initial data from the bound component class, but also update it: <form #f="ngForm"> ... <input type="text" placeholder=
