尝试通过 js 使用索引数组进行自定义实时搜索

Question

这是我的代码...我基本上想做这一行 (td = tr[i].querySelectorAll(".table-data")[0];) 我想要这个部分...[0]变成这样 [0,5]

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

您还需要遍历每一列并检查是否找到该值。

function myFunction() {
  var input, filter, table, tr, td, i, txtValue;
  input = document.querySelector("#myInput");
  filter = input.value.toUpperCase();
  table = document.querySelector("#myTable");
  tr = table.querySelectorAll(".row");
  for (i = 0; i < tr.length; i++) {
    td = tr[i].querySelectorAll(".table-data");
    if (td) {
      let valid = false;
      for (t = 0; t < td.length; t++) {
        txtValue = td[t].textContent || td[t].innerText;
        if (txtValue.toUpperCase().indexOf(filter) > -1) {
          valid = true;
        }
      }
      
      if (valid) {
        tr[i].style.display = "";
      } else {
        tr[i].style.display = "none";
      }
    }       
  }
}
