reactjs - React 无法识别 DOM 元素上的 `computedMatch` 属性。

Question

我正在使用带有 bootstrap-v3 的 React TypeScript，问题出在 Breadcrumb 和 React-router-dom 上:

react 提示警告:React 无法识别 DOM 元素上的 compulatedMatch 属性。

这个computeMatch是怎么来的？ 我正在使用最新的react-bootstrap:

第一行是带有奇怪的compatedmatch属性的html节点:

<ol computedmatch="[object Object]" location="[object Object]" role="navigation" aria-label="breadcrumbs" class="breadcrumb"><li class=""><span href="#" role="button"><a href="/">Home</a></span></li><li class=""><span href="#" role="button"><a href="/">React</a></span></li><li class=""><span href="#" role="button"><a href="/name">Author</a></span></li></ol>

以下是 Breadcrumb.js lib 文件:

import _extends from "@babel/runtime-corejs2/helpers/esm/extends";
import _objectWithoutPropertiesLoose from "@babel/runtime-corejs2/helpers/esm/objectWithoutPropertiesLoose";
import _inheritsLoose from "@babel/runtime-corejs2/helpers/esm/inheritsLoose";
import classNames from 'classnames';
import React from 'react';
import BreadcrumbItem from './BreadcrumbItem';
import { bsClass, getClassSet, splitBsProps } from './utils/bootstrapUtils';

var Breadcrumb =
/*#__PURE__*/
function (_React$Component) {
  _inheritsLoose(Breadcrumb, _React$Component);

  function Breadcrumb() {
    return _React$Component.apply(this, arguments) || this;
  }

  var _proto = Breadcrumb.prototype;

  _proto.render = function render() {
    var _this$props = this.props,
        className = _this$props.className,
        props = _objectWithoutPropertiesLoose(_this$props, ["className"]);

    var _splitBsProps = splitBsProps(props),
        bsProps = _splitBsProps[0],
        elementProps = _splitBsProps[1];

    var classes = getClassSet(bsProps);
    return React.createElement("ol", _extends({}, elementProps, {
      role: "navigation",
      "aria-label": "breadcrumbs",
      className: classNames(className, classes)
    }));
  };

  return Breadcrumb;
}(React.Component);

Breadcrumb.Item = BreadcrumbItem;
export default bsClass('breadcrumb', Breadcrumb);

我的 tsx 代码是:

<Router>
          <Switch>
            <Breadcrumb computedMatch={undefined}>
              <Breadcrumb.Item componentClass="span">
                <Link to="/">Home</Link>
              </Breadcrumb.Item>
              <Breadcrumb.Item componentClass="span">
                <Link to="/">React</Link>
              </Breadcrumb.Item>
              <Breadcrumb.Item active={false} componentClass="span">
                <Link to="/name">Author</Link>
              </Breadcrumb.Item>
            </Breadcrumb>
            <Route path="/:name" component={gridInstance} />
          </Switch>
        </Router>

您收到此警告是因为您放置 <Switch> 的方式所致。标签。只保留<Route/>和<Redirect/> <Switch> 内的标签标签来消除警告。

类似这样的事情:

<Router>
    <Breadcrumb computedMatch={undefined}>
      <Breadcrumb.Item componentClass="span">
        <Link to="/">Home</Link>
      </Breadcrumb.Item>
      <Breadcrumb.Item componentClass="span">
        <Link to="/">React</Link>
      </Breadcrumb.Item>
      <Breadcrumb.Item active={false} componentClass="span">
        <Link to="/name">Author</Link>
      </Breadcrumb.Item>
    </Breadcrumb>
    <Switch>
      <Route path="/:name" component={gridInstance} />
    </Switch>
</Router>
