handleClick on row and checkbox in datatable

Question

Updated I use material ui next, Table component, and Table is stateless component, and also I have constructor component EnhancedTable. Also in Table component when I go map through data, I need to check if selected props(array) has the same item as on data array . How should I check const isSelected = selected.includes(item) when I map through data array. Also when I click I catch error that selected.includes is not a function

unselectSelected={() => onSelect(selected =>{
                        debugger
                        console.log(selected)})}

Table component

    let defaultCellRenderer = ({item, key}) =>
    item[key]

const Table = props => {
    const {data, columns, children, selectable, order, selected, onSelect, onDelete, onSearch, onDuplicate, onSort, search, onUnselectAll} = props

    return (
        <div>
            {selectable &&
                <EnhancedTableToolbar
                    numSelected={selected.length}
                    handleSearch={() => onSearch(data)}
                    value={search}
                    // unselectSelected={() => onUnselectAll(selected)}
                    unselectSelected={() => onSelect(selected =>{
                        debugger
                        console.log(selected)})}
                    deleteSelected={() => onDelete(selected)}
                    duplicateSelected={() => onDuplicate(selected)}
                /> }
            <MuiTable >
                {selectable
                    ? <EnhancedTableHead
                        columns={columns}
                        numSelected={selected.length}
                        order={order}
                        // onSelectAllClick={() => onSelect(Object.keys(new Array(selected.length).fill(0)))}

                        onSelectAllClick={() => onSelect(
                            console.log('click')
                        )}
                        onRequestSort={property => event => onSort(event, property)}
                    />

It seems to me that you've got several things wrong ( and a few things that are maybe just strange) here. Because I don't know the structure of data in your example I can't tell you if your check here for const isSelected = selected.includes(item) is working properly or not. If an item in your data array is a single value this will work. For example if you had:

const data = [ 1,2,3,4 ]

And

const selected = [1,2]

You could do the check the way you are currently doing and it would work. const isSelected = selected.includes(item)

But if your data is for example an object array like:

const data = [ {id: 1},{id: 2},{id: 3} ]

And

const selected = [{id:1}]

Then you would need to check the id value like this:

const isSelected = selected.some((i) => i.id === item.id )

And also it looks like you are not setting selected to a new value when you filter it in your onClick method which is probably why you're getting the selected.includes is not a function error. You should be doing this instead.

onClick={() => onSelect(isSelected ? selected = selected.filter(x => x != item) : [...selected, item])}

I'm not sure why you don't just have a your onSelect method handle both the select and unselect of a row. Something like:

onClick={() => this.onSelect()}

And then outside your render method:

onSelect() {
    isSelected ? selected = selected.filter(x => x != item) : [...selected, item]
}

Hope that helps.
