This code represents a React JSX snippet that renders a quantity incrementor UI component. Here's a step-by-step breakdown of what each part does:
-
<div>
element:- A container element with
className={styles.quantityIncrementor}
applies a specific CSS class for styling. - The style is likely managed through a CSS module (
styles
).
- A container element with
-
First
<Image>
element:- Displays an image (
plus-icon.svg
) that serves as a button. - When this image is clicked, the
incrementQuantity
function is called, presumably increasing the quantity.
- Displays an image (
-
<input>
element:- Renders an input field of type
number
for the user to view or edit the quantity. name="quantity"
andid="quantity"
are identifiers for the field.className={styles.itemQuantity}
applies CSS styles for visual formatting.defaultValue={quantity}
initializes the input with aquantity
value (likely a state variable in React).min={1}
restricts the quantity to a minimum value of 1.onChange={(e) => setQuantity(Number(e.target.value))}
:- Updates the quantity state using a
setQuantity
function whenever the user modifies the input value. - The value from the input (
e.target.value
) is converted to a number.
- Updates the quantity state using a
- Renders an input field of type
-
Second
<Image>
element:- Displays another image (
minus-icon.svg
) that acts as a button. - When clicked, it executes the
decrementQuantity
function, likely decreasing the quantity.
- Displays another image (
Overall Purpose:
This code is a reusable component for quantity adjustment in a user interface. It allows users to increase or decrease a numeric value (e.g., product quantity) through:
- Clicking the "+" and "-" icons (handled by
incrementQuantity
anddecrementQuantity
). - Manually entering a value in the input field (handled by the
onChange
function).
