                return <tr key={index} onClick={this.projectDetails(item, index)}>
                    <td>{item.name}</td>
                    <td>{item.description}</td>

                        function() {
                            showconfrim("Do you want to delete this Project?");
                        }
                    }></i></td>
                </tr>
            });

method

 projectDetails(item, index) {
        console.log(index);
    }

constructor

constructor(props) {
        super(props);

        this.state = {
            activePage: 1,
            projectList: []
        };

        this.projectDetails = this.projectDetails.bind(this);
    }
