大家好我需要选择名称和事件以及电子邮件并在其中搜索其中一个,因为当我输入getElementsByTagName(“td”)[1]时你可以看到;我有名字的搜索,当我把getElementsByTagName(“td”)[2];我可以在事件中搜索,但我需要搜索其中的3个而不是全部3个 谢谢你的帮助:)

<!DOCTYPE html>
<html>
<body>

<input type="text" id="myInput" onkeyup="myFunction()" placeholder="Search for names..">
    <table id="myTable" class="table table-hover table-inverse tablesorter">
        <thead>
            <tr class="header">
        <th> 
            <input type="checkbox" value="All" id="selectIDs" />
            </label>
        </th>
          <th>Name</th>
          <th>Event</th>
          <th>Email</th>
          <th>Iban</th>
          <th>UID</th>
          <th>Date</th>

            </tr>
        </thead>
          <tbody>
             <% uids.forEach(function(uid){ %>
            <tr>
              <td><input type="checkbox" class="checkbox" name="productIds" value="<%=uid._id%>"></td>     
              <td ><%= uid.name %></td>
              <td ><%= uid.event %></td>
              <td ><%= uid.email %></td>
              <td><%= uid.iban %></td>
              <td><%= uid.uid %></td>
              <td><%= uid.readableDate %></td>

            </tr>
          <% }) %>

          </tbody>

    </table>

<p id="demo"></p>

<script>
function myFunction() {
  // Declare variables 
  var input, filter, table, tr, td, i;
  input = document.getElementById("myInput");
  filter = input.value.toUpperCase();
  table = document.getElementById("myTable");
  tr = table.getElementsByTagName("tr");

  // Loop through all table rows, and hide those who don't match the search query
  for (i = 0; i < tr.length; i++) {
    td = tr[i].getElementsByTagName("td")[1];

    if (td) {
      if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {
        tr[i].style.display = "";
      } else {
        tr[i].style.display = "none";
      }
    } 
  }
}
</script>

</body>

答案 0 :(得分:1)

你可以使用你需要的3行元素的数组,如

let newArray = new Array();
if(tr[i].getElementsByTagName("td")[1]) newArray.push(tr[i].getElementsByTagName("td")[1].innerHTML.toUpperCase());
if(tr[i].getElementsByTagName("td")[2]) newArray.push(tr[i].getElementsByTagName("td")[2].innerHTML.toUpperCase());
if(tr[i].getElementsByTagName("td")[3]) newArray.push(tr[i].getElementsByTagName("td")[3].innerHTML.toUpperCase());

然后你在这个数组中搜索:

if (newArray.filter((e,i) => e.indexOf(filter) > -1).length > 0) {
    tr[i].style.display = "";
} else {
     tr[i].style.display = "none";
}

或者

if (newArray.indexOf(filter) > -1) {
    tr[i].style.display = "";
} else {
     tr[i].style.display = "none";
}

如果你想检查每个字母或完整的单词。

这样更好吗?
