Select React 中的表格行

Question

我试图在我的 React Material App 中一次只选择一行。 我现在的问题是它突出显示了许多行。 我只需要一次突出/选择一行。

代码

const [selected, setSelected] = React.useState([]);

const selectFood = (event, food) => {
  const selectedIndex = selected.indexOf(food.name);
  let newSelected = [];

  if (selectedIndex === -1) {
    newSelected = newSelected.concat(selected, food.name);
  } else if (selectedIndex === 0) {
    newSelected = newSelected.concat(selected.slice(1));
  } else if (selectedIndex === selected.length - 1) {
    newSelected = newSelected.concat(selected.slice(0, -1));
  } else if (selectedIndex > 0) {
    newSelected = newSelected.concat(
      selected.slice(0, selectedIndex),
      selected.slice(selectedIndex + 1)
    );
  }

  setSelected(newSelected);
};

const isSelected = row => selected.indexOf(row.name) !== -1;

Answer 1

如果您只想 select 单行 - 那么这肯定会起作用（不需要您编写的复杂代码）

const selectFood = (event, food) => {
    let newSelected = [food.name];
    setSelected(newSelected);
  };
