ngmodel

问题 I have an Angular4 app that captures data from a form and stores in DynamoDB. It uses ngModel to support two-way data binding and on the display all looks good. Issue comes into play because of an input field typed as 'text' bound to Typescript 'number' field. Seems to be changing the type of the object value to 'string'. I would simply change the HTML Input type to 'number' except for the unnecessary and undesirable increment/decrement decorators on the form field (and hiding them seems to

问题 I have arrived at a lengthy syntax iterating over data[areaId].main.points . Since the data is bound via [(ngModel)] , it looks atrociously in my opinion. Something like this. <div *ngFor="let item of data[areaId].main.points; let index = index; let ..." ...> <input [(ngModel)]="data[areaId].main.points[index].e" ... > <input [(ngModel)]="data[areaId].main.points[index].n" ... > ... </div> Usually, when the syntax gets ugly, it's a strong indication that the design sucks and should be

问题 i have array of objects, here if the date is picked from the datetime calender, the value is not binding to that object, but if i change the date manually then it works, but if i select from calendar then the value is nit binding.

问题 I am receiving a value, that I display to the user in a text field. The idea is for him to be able to edit this value, and then send it back. In the case of money, let's say I store the amount in cents, but I want to display it in dollars. Here is an idea of the code I have that display the value I receive : <input type="text" [(ngModel)]="myValue" value="{{myValue}}" /> I tried this without success : <input type="text" [(ngModel)]="myValue/100" value="{{myValue/100}}" /> How can I display
