反应| 虚拟DOM元素点击事件未触发

Question

I'm using Ant Design and React js for my Project.

Problem

I have a button in Popover and having click event for that button. The problem is button click event is not triggering.

JS Code

const content = (
  <div className="RecurringPopover"> 
    <button onClick={this.handleClick}> Popover Button </button> 
  </div>
);

Full Code with scenario in stackblitz

Answer 1

You have defined content outside the class and then supplying this.handleClick as a click handler to it. However outside class, this does not point to the class . You should define content inside class and use this.content to access that.

handleClick() {
      alert('test');
    }
// put it inside class
 content = (
  <div className="RecurringPopover"> 
    <button onClick={this.handleClick}> Popover Button </button> 
  </div>
);
  render() {
    return (
      <div>
        <Row>
          <Col span={12}>      
          // Use this.content instead of just content
          <Popover content={this.content} title="Title">
            <span type="primary">Hover me (Popover Button)</span>

只需将“ content ”带入类内部，然后通过“ this.content ”将其传递给组件，它将起作用。
