antd单选框Radio问题

http404
  • 242

用到了antd的Radio单选框出了点问题,页面初始化表格数据第一条是默认不选上,第二条第三条分别默认选上第二个跟第一个,当我点击页面上 “请求新数据” 按钮时,页面重新setState了一次,表格第一条第三个默认正常选上,第二条不选上,但给我选上了,这个问题就来了,打断点发现checked这个值是false的,不知道为什么还选上

下面接口格式是根据后台请求回来的格式模拟的,代码不多,用到了antd的Table

你这文档都没看完,就写代码了,差评。

<RadioGroup onChange={this.onChange} value={this.state.value}>
        <Radio value={1}>A</Radio>
        <Radio value={2}>B</Radio>
        <Radio value={3}>C</Radio>
        <Radio value={4}>D</Radio>
      </RadioGroup>

这个才是RadioGroup的用法,丛植RadioGroup的value值就可以了。

然后不得不说,代码写的比较丑,但是给的例子可以直接跑起来,这点不错。
丑指的这里

if (userName) {
                        if (userName.a) {
                            for (let i = 0; i < userName.a.length; i++) {
                                if (userName.a[i] === getUserName) {
                                    userNames = '100%造假';
                                }
                            }
                        }
                        if (userName.b) {
                            for (let j = 0; j < userName.b.length; j++) {
                                if (userName.b[j] === getUserName) {
                                    userNames = '大概率';
                                }
                            }
                        }
                        if (userName.c) {
                            for (let k = 0; k < userName.c.length; k++) {
                                if (userName.c[k] === getUserName) {
                                    userNames = '小概率';
                                }
                            }
                        }
                    }
