React JS：在onChange下拉传递事件（Ant设计） [英] React JS: Pass event inside onChange drop down (Ant Design)

问题描述

我的表格中有一个下拉列表（ https://ant.design/components/select）。在这个选择下拉列表中，我有onChange来调用一个函数。在'onChange'里面我想把这个事件作为参数传递给我的函数。问题是：当onChange发生时，只传递选定的值，但我想要整个事件。

I have a drop down in my form (https://ant.design/components/select). In this select drop down I have the onChange to call a function. Inside 'onChange' I want to pass the event as a parameter to my function. The problem is: when the onChange occurs, only the selected value is passed, but I want the entire event.

以下是代码：

export default class MyForm extends Component {
    constructor() {
        super();

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

    handleOnChange = (event) => {
        console.log(event); // here I'm receiving only the value selected (1 or 2)
    }

    render() {
        render(
           <Form>
              <Select onChange={this.handleOnChange}>

                      <Option value="1">text 1</Option>
                      <Option value="2">text 2</Option>
              </Select>
           </Form>
        )
    }
}

在console.log（）中，我只收到所选的值。有没有办法将整个事件对象传递给函数handleOnChange（）？

In the console.log() I'm receiving only the selected value. Is there a way to pass the entire event object to the function handleOnChange()?

推荐答案

我找到了一个解决方案。只需使用：onSelect（），传递值和事件。

I found a solution. Just use: onSelect(), passing the value and the event.

handleOnChange = (value, event) => {
        ...code here        
}

    render() {
        render(
           <Form>
              <Select onSelect={(value, event) => this.handleOnChange(value, event)}>

                      <Option value="1">text 1</Option>
                      <Option value="2">text 2</Option>
              </Select>
           </Form>
        )
    }
