javascript - 使用 JavaScript 过滤表格时，可展开行不会折叠

问题描述

该表有一个可展开的行，显示行的详细信息。我使用 JavaScript 来搜索和过滤特定的行内容。但是在使用搜索过滤器时，它会显示结果但无法展开详细信息。我使用了引导collapse类。

可以在此处找到显示可扩展行的片段。

这是我的过滤器代码：

function myFunction() {
  var input, filter, table, tr, td, i, txtValue;
  input = document.getElementById("myInput");
  filter = input.value.toUpperCase();
  table = document.getElementById("myTable");
  tr = table.getElementsByTagName("tr");
  for (i = 0; i < tr.length; i++) {
    td = tr[i].getElementsByTagName("td")[0];
    if (td) {
      txtValue = td.textContent || td.innerText;
      if (txtValue.toUpperCase().indexOf(filter) > -1) {
        tr[i].style.display = "";
      } else {
        tr[i].style.display = "none";
      }
    }       
  }
}

回答工作过渡

function showText() {
    elemContainer.style.opacity = 0;
}

function change() {
    elemContainer.style.opacity = 1;
    elem.innerHTML = text[counter];
    setTimeout(showText, 2500);

    counter++;
    if (counter >= text.length) {
        counter = 0;
        // clearInterval(inst); // uncomment this if you want to stop refreshing after one cycle
    }
}

解决方案

正如@swati 建议的那样，替换table.getElementsByTagName("tr")为table.querySelectorAll("tr[data-toggle='collapse']")解决问题。

这是工作代码：

function myFunction() {
    var input, filter, table, tr, td, i, txtValue;
    input = document.getElementById("myInput");
    filter = input.value.toUpperCase();
    table = document.getElementById("myTable");
    tr = table.querySelectorAll("tr[data-toggle='collapse']");
    for (i = 0; i < tr.length; i++) {
        td = tr[i].getElementsByTagName("td")[0];
        if (td) {
            txtValue = td.textContent || td.innerText;
            if (txtValue.toUpperCase().indexOf(filter) > -1) {
                tr[i].style.display = "";
            } else {
                tr[i].style.display = "none";
            }
        }
    }
}
