从浏览器以html格式运行javascript

催化剂

我在这篇文章的jsfiddle中有一个工作正常的javascript，并且希望在我的浏览器中本地运行。

我不太确定我还需要添加什么其他内容才能使其正常运行。我读了很多帖子，但仍然不知道如何解决它。

以下是我的操作，但是运行代码段时出现错误，有人可以帮忙吗？谢谢。

$(document).ready(function myFunction() {

  // Declare variables 
  var input = document.getElementById("myInput");
  var filter = input.value.toUpperCase();
  var table = document.getElementById("myTable");
  var trs = table.tBodies[0].getElementsByTagName("tr");

  // Loop through first tbody's rows
  for (var i = 0; i < trs.length; i++) {

    // define the row's cells
    var tds = trs[i].getElementsByTagName("td");

    // hide the row
    trs[i].style.display = "none";

    // loop through row cells
    for (var i2 = 0; i2 < tds.length; i2++) {

      // if there's a match
      if (tds[i2].innerHTML.toUpperCase().indexOf(filter) > -1) {

        // show the row
        trs[i].style.display = "";

        // skip to the next row
        continue;

      }
    }
  }

});

#myInput {
  background-image: url('/css/searchicon.png');
  background-position: 10px 12px;
  background-repeat: no-repeat;
  width: 100%;
  font-size: 16px;
  padding: 12px 20px 12px 40px;
  border: 1px solid #ddd;
  margin-bottom: 12px;
}

#myTable {
  border-collapse: collapse;
  width: 100%;
  border: 1px solid #ddd;
  font-size: 18px;
}

#myTable th,
#myTable td {
  text-align: left;
  padding: 12px;
}

#myTable th {
  width: 20%;
}

#myTable tr {
  border-bottom: 1px solid #ddd;
}

#myTable tr.header,
#myTable tr:hover {
  background-color: #f1f1f1;
}

首先，您需要添加jquery库，下一步是将onkeyup事件添加到您的输入中以启动功能

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

例子：

function myFunction() {

  // Declare variables 
  var input = document.getElementById("myInput");
  var filter = input.value.toUpperCase();
  var table = document.getElementById("myTable");
  var trs = table.tBodies[0].getElementsByTagName("tr");

  // Loop through first tbody's rows
  for (var i = 0; i < trs.length; i++) {

    // define the row's cells
    var tds = trs[i].getElementsByTagName("td");

    // hide the row
    trs[i].style.display = "none";

    // loop through row cells
    for (var i2 = 0; i2 < tds.length; i2++) {

      // if there's a match
      if (tds[i2].innerHTML.toUpperCase().indexOf(filter) > -1) {

        // show the row
        trs[i].style.display = "";

        // skip to the next row
        continue;

      }
    }
  }

}

#myInput {
      background-image: url('/css/searchicon.png');
      background-position: 10px 12px;
      background-repeat: no-repeat;
      width: 100%;
      font-size: 16px;
      padding: 12px 20px 12px 40px;
      border: 1px solid #ddd;
      margin-bottom: 12px;
    }
    
    #myTable {
      border-collapse: collapse;
      width: 100%;
      border: 1px solid #ddd;
      font-size: 18px;
    }
    
    #myTable th,
    #myTable td {
      text-align: left;
      padding: 12px;
    }
    
    #myTable th {
      width: 20%;
    }
    
    #myTable tr {
      border-bottom: 1px solid #ddd;
