Question

我已经实现了一个可折叠的div，该div在单击“阅读更多”按钮时会扩展。一切正常。但是通过扩展按钮位置会出错。当卡未展开时，我希望按钮位于卡上按钮所在的相同位置。

这是我的代码

 * {

#more {
  display: none;
}

.wrap-collabsible {
  margin-bottom: 1.2rem 0;

    function myFunction() {
      var dots = document.getElementById("dots");
      var moreText = document.getElementById("more");
      var btnText = document.getElementById("myBtn");
      document.getElementById('hideOnClick').innerHTML = "Hello to the world";
      document.getElementById('conditional-tag').style.display = "block";
      if (dots.style.display === "none") {
        dots.style.display = "inline";
        btnText.innerHTML = "Read more";
        moreText.style.display = "none";
        document.getElementById('hideOnClick').innerHTML = "No. 60, Jalan Pendamar Indah 1B, Taman Pendamar Indah, Pelabuhan Klang, Selangor";
        document.getElementById('conditional-tag').style.display = "none";
      } else {
        dots.style.display = "none";
        btnText.innerHTML = "Read less >";
        moreText.style.display = "inline";
      }
    }
  </script>
</div>
  </div>

我要在卡片折叠前后将按钮放在相同的位置。我怎么得到它？

在这里，我删除了const http = require("http"); const port = 4098; let app = http.createServer((request, response) => { let url = request.url; switch (url) { case "/": getStaticFile(response, "./public/home.html"); break; case "/contact": getStaticFile(response, "./public/contact.html"); break; default: response.send("Oops...Page Not Found!"); break; } }); function getStaticFile(response, pathToFile) { fs.readFile(pathToFile, function(error, data) { if (error) { response.writeHead("500", { "Content-Type": "text/plain" }); response.end("500 - Internal Server Error"); } if (data) { response.writeHead("200", { "Content-Type": "text/html" }); response.end(data); } }); } app.listen(port, () => { !console.log(`Listening to connections on port ${port}`); });，并添加了float: right并设置了position:relative;。

right:250px;

您只需要用类包装div-容器div内的内部包装盒和包装纸，这将解决您的问题。当前的问题是包装器div的宽度不为100％，因此，您会看到“ Read Less”按钮没有正确放置。

import "react-dates/initialize";
import "react-dates/lib/css/_datepicker.css";
import { SingleDatePicker } from "react-dates";

export default class ExpenseForm extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      createdAt: moment(),
      calendarFocused: false
    };

    this.onDateChange = this.onDateChange.bind(this);
    this.onFocusChange = this.onFocusChange.bind(this);
  }

  onDateChange(createdAt) {
    this.setState(() => ({ createdAt }));
  }

  onFocusChange({ focused }) {
    this.setState(() => ({
      focused
    }));
  }

  render() {
    return (
      <div>
        <SingleDatePicker
            date={this.state.createdAt}
            startDateId="MyDatePicker"
            onDateChange={this.onDateChange}
            focused={this.state.calendarFocused}
            onFocusChange={this.onFocusChange}
            id="SDP"
          />

      </div>
    );
  }
}
