**{data.listArts.items.map((art, index) => {
return (
<a className="thumbnail" key={index}>
<img src={art.ArtURL}/>
</a>
);})}**
I am using the above code to display multiple items on the UI. The data.listArts.items array consists of approximately 100 elements.
After the completion of the map execution, I need to trigger a function that can interact with the generated HTML in reactJS.
One way to handle the lack of a callback function in the map method when it reaches the end of an array is by manually checking if the last element has been reached and then invoking a custom function.
const totalItems = data.listArts.items.length
data.listArts.items.map((art, index) => {
if(index === totalItems - 1) {
/* Custom callback invocation goes here */
}
return (
<a className="thumbnail" key={index}>
<img src={art.ArtURL}/>
</a>
);})Determine the array length by index
data.listArts.items.map((art, index) => {
if(data.listArts.items.length -1 == index){
//perform desired action here, such as setting a flag
}
return (
<a className="thumbnail" key={index}>
<img src={art.ArtURL}/>
</a>
);}
)}
