如何在不单击输入的情况下在框内搜索答案

【问题标题】：How can i search inside the box without clicking enter如何在不单击输入的情况下在框内搜索
【发布时间】：2021-12-05 13:09:23
【问题描述】：

我从网站获取 .json 数据并将该数据打印为列表。例如，当我在搜索框中输入“a”时，我希望它过滤列表并在表格中显示结果。

到目前为止，我已经编写了从 w3 学校平台获取过滤器的代码，但由于某种原因我无法过滤列表。

【问题讨论】：

请点击edit，然后点击[<>]，并在minimal reproducible example 上发布您的努力。你的代码搞砸了。如果这不是 PHP 问题，请仅发布 HTML、JS 和 CSS
非常感谢您的帮助，我仍在努力尽快学习规则。
为什么你有一个带有
的标题？如果您想要更多间距，请使用边距
我更新了我的答案。您的 ID 中有错字，javascript 中有一些十六进制字符

标签： javascript php html

【解决方案1】：

我的表，不是我的表
在您的 JavaScript 中使用松散的 Hex 0A

代码可以简化

window.addEventListener("load", () => {
  document.getElementById("myInput").addEventListener("input", e => {
    const filter = e.target.value.toUpperCase();
    document.querySelectorAll("#MyTable tbody tr")
      .forEach(row => {
        row.hidden = filter && !row.cells[5].textContent.toUpperCase().includes(filter)
      })
  })
})

window.addEventListener("load", () => {
  document.getElementById("myInput").addEventListener("input", e => {
    const filter = e.target.value.toUpperCase();
    document.querySelectorAll("#MyTable tbody tr")
      .forEach(row => {
        row.hidden = filter && !row.cells[5].textContent.toUpperCase().includes(filter)
      })
