React Js enable/disable elements from an array
React Js enable/disable elements from an array:In Reactjs, you can enable/disable elements from an array by using conditional rendering. First, you would create an array of elements and define a state variable to track the enabled/disabled status.
Then, in your JSX code, you can map over the array and render each element based on the enabled/disabled state. To enable/disable an element, you would update the state variable accordingly. This triggers a re-render, and the enabled/disabled elements will be displayed or hidden based on the updated state.

How can Reactjs be used to enable/disable elements within an array?
This Reactjs code demonstrates how to enable/disable elements from an array. The code uses the useState
hook to define an array of objects, each containing an id
, name
, and enabled
property. The toggleElement
function is used to toggle the enabled
status of an element based on its id
.
When rendering, the arrayData
is mapped and displayed as a list of checkboxes and names. Clicking on a checkbox triggers the toggleElement
function, which updates the enabled
property of the corresponding element in the state.
