问有什么方法可以在react组件中获得道具吗？

var path = this.props.data.map(function(item, i) {
    // compute coordinates
    return coordinates;
});
console.log(path); // [coordinates_for_data_item_1, coordinates_for_data_item_2, coordinates_for_data_item_3]

    constructor(props) { // <<------ see them

      L.mapbox.accessToken = 'here my token';
      var map = L.mapbox.map('map', 'some info', { zoomControl: false }).setView([48, 17], 5);

      new L.Control.Zoom({ position: 'topright' }).addTo(map);

      var path = [];

      this.props.data.map(function(item, i) {
        var icon;
        if (i === 0) {
