如何更改react-bootstrap中活动单选按钮的背景颜色?

问题描述

限时删除！！

在React项目中，我有单选按钮，用于列出日历日期和日期.我的意图是更改那些单选按钮的背景色并保持不变.在屏幕上单击时，它不应消失.

In a React project I've radio buttons enlisting calendar dates and days. My intention is to change the background color of those radio buttons and also persist it. It should not fade away when clicked on screen.

以下是供参考的代码:

{newDate.map((data, i) => (
          <ButtonGroup toggle style={{ width: "100%" }}>
            <GridListTile style={gridListStylePhoto}>
              <h5>{currday(data.getDay())}</h5>
              <ToggleButton
                key={i}
                type="radio"
                active="true"
                variant="light"
                name="radio"
                value={currday(data.getDay()) + " " + data.getDate()}
                checked={radioValue === data.getDate()}
                onChange={(e) => {
                  handleChange(e);
                }}
              >
                <br />
                {data.getDate()}
              </ToggleButton>
            </GridListTile>
          </ButtonGroup>
        ))}

以下是样式参考:

input[type="checkbox"],
input[type="radio"] {
  display: none;
}
.btn-light {
  background-color: transparent;
  border: transparent;
}

.btn-light:checked {
  background-color: red // Here is color doesn't change
}

推荐答案

您可以使用现有的onChange事件为每个单选按钮切换类.

You can toggle the class for each radio button using your existing onChange event.

const handleChange = (e) => {
    const newData = e.target.value;
    var elems = document.querySelectorAll(".toggleButtonNew.active");
    [].forEach.call(elems, function (el) {
      el.classList.remove("active");
    });
    e.target.closest("label").classList.toggle("active");
    setRadioValue(newData);
};

然后将所需的样式添加到该类中

And add your desired styles to that class

.active {
    background-color: red !important;
}
