In this blog, I will give you the piece of code to access the current SharePoint list item using JavaScript. Below is the piece of code to achieve the same.

function getCurrentListItem(success, error) {
var context = SP.ClientContext.get_current();
var web = context.get_web();
var currentList = web.get_lists().getById(_spPageContextInfo.pageListId);
var currentListItem = currentList.getItemById(_spPageContextInfo.pageItemId);
context.load(currentListItem);
context.executeQueryAsync(
function () {
var currentEmpItem= currentListItem.get_item(‘Employee_x0020_Name’);
if (currentItem!= null) {
alert(“Your employee name is “,+currentEmpItem);

}

error
);
