Default value in input does not work when using ngModel

Question

I'm trying to add paging to my pdf viewer in angular and I have the following code:

<input value="1" type="number" min="1" max="{{ totalPages }}" [(ngModel)]="page">/{{ totalPages }}

I want to set the default value of the input to be "1", but this does not work. If I take out

[(ngModel)]="page"

then it work perfectly fine. What is the cause of this?

The input gets bound to the value of page and thus, the default value=1gets overriden. But page is probably empty / not inialized in your component, so the value is just blank. You need to initialize your page with 1 in your component e.g. like so:

page: number = 1

Then, you can also get rid of the value=1 initialization within the template.
