Property binding in angular 8

Property Binding is a one-way data-binding technique. In property binding, we bind a property of a DOM element to a field which is a defined property in our component TypeScript code. Actually, Angular internally converts string interpolation into property binding.

In this, we bind the property of a defined element to an HTML DOM element.

Syntax:

<element [property]= 'typescript_property'>

Approach:

• Define a property element in the app.component.ts file.
• In the app.component.html file, set the property of the HTML element by assigning the property value to the app.component.ts file's element.

Example 1: setting value of an input element using property binding.

app.component.html

app.component.ts

Output:

👁 Image

Example 2: getting source of the image using property binding.

app.component.html

app.component.ts

Output:

👁 Image

Example 3: disabling a button using property binding.

app.component.html

app.component.ts

Output:

👁 Image
