单击该行时在引导程序样式表中选择一行

Question

How to highlight a row from the table when it is clicked? I have tried using onClick function but I cannot achieve it.

This is the function I used for mapping the table data to td tag.

displayData() {   
       let x;
       if (this.props.data) {
       x = this.props.data.map(item => (
       <tr>
       <td> {item.height} </td>
       </tr>
      ));
    }
    return x;
    }

Here I have called this function inside the render function.

        <Table id="tableId" >
        <thead>
        <tr>
        <th> height </th>
       </tr>
      </thead>
     <tbody> {this.displayData()} </tbody>
     </Table>

You have to provide an key to every td , then a className property that will change depending on the id existing currently in the state and of course an onClick event handler that will fill in the state with the clicked id, therefore this block:

  if (this.props.data) {
   x = this.props.data.map((item,key) => (
   <tr>
   <td
     key={key}
     onClick={this.handleCellClick(key)}
     className={`${this.state.checkedId===key? 'highlighted-cell': ''}`}
      > {item.height} </td>
   </tr>
  ));
}

and your handleCellClick function can be implemented as follows:

handleCellClick = (key) => (event) => {

if(this.state.checkedId===key){
   this.setState({
      checkedId: '',
     });
   }else{
   this.setState({
      checkedId: key,
     });
   }
  }

finally your highlited-cell class can be written as per your preferences:

.highlighted-cell {
   background-color: blue;
   }
