Looking for a simple solution - I have a component with a string that I want to display in an input field.
I attempted the following approach, but it didn't work as expected:
import {Component} from "@angular/core";
@Component({
selector: 'my-component',
template: `
<input type="text" ([ngModel])="myVar" >
`
})
export class MyComponent{
constructor(){
}
myVar: string = "Hello World"
}
([ngModel]) is incorrectly written, it should be [(ngModel)]. Remember the order of parentheses.
A helpful mnemonic to remember is banana in the box. The opening square bracket [ resembles a box and the opening parenthesis ( resembles a banana.
Additionally, there appears to be a spelling error in the path to your template file. It states ./my-compoent instead of ./my-component which is likely the correct file name.
Your solution:
([ngModel])="myVar" should be changed to [(ngModel)]="myVar"
Also, remember to add a name field in the input type like this: name="myVar"
Here is an example implementation :
import { Component } from "@angular/core";
@Component({
selector: 'my-component',
templateUrl: './my-compoent.template.html';
})
export class MyComponent {
myVar: string = "Hello World"
constructor() { }
}
Don't forget to include the name attribute in your HTML input tag as well:
<input type="text" name="myVar" [(ngModel)]="myVar" >
