如何解决如何使用javascript使用值和颜色过滤表

我有用于按值过滤表的代码，

function myFunction() {
  // Declare variables
  var input,filter,table,tr,td,i,txtValue;
  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")[0];
    if (td) {
      txtValue = td.textContent || td.innerText;
      if (txtValue.toUpperCase().indexOf(filter) > -1) {
        tr[i].style.display = "";
      } else {
        tr[i].style.display = "none";
      }
    }
  }
}

这是我的桌子

Table

这是生成表的脚本 

$(document).ready(function(){
 $('#load_data').click(function(){
  $.ajax({
   url:"OutputNew.csv",dataType:"text",success:function(data){
    var employee_data = data.split(/\r?\n|\r/);
    var table_data = '<input type="text" id="myInput" onkeyup="myFunction()" placeholder="Search for names.."><input type="text" id="myInput" onkeyup="myFunction()" placeholder="Search Color"><table id="myTable" class="table table-bordered table-striped">';
    for(var count = 0; count<employee_data.length; count++) {
     var cell_data = employee_data[count].split(',');
     table_data += '<tr>';
     for(var cell_count=0; cell_count<cell_data.length; cell_count++){
      if(count === 0){
       table_data += '<th>'+cell_data[cell_count]+'</th>';
      }else{
          if(cell_data[cell_count] .includes("Not Matching")){
                var ret = cell_data[cell_count].replace('Not Matching','');
                if (ret == ""){
                  table_data += '<td>'+ret+'</td>'
                }else{
                  table_data += '<td><span class="badge-danger">'+ret+'</span></td>'
                }
          }else if(cell_data[cell_count] .includes("Matching")){
                var ret = cell_data[cell_count].replace('Matching','');
                if (ret == ""){
                  table_data += '<td>'+ret+'</td>'
                }else{
                  table_data += '<td><span class="badge-complete">'+ret+'</span></td>';
                }
          }else{
              table_data += '<td>'+cell_data[cell_count]+'</td>';
          }
      }
     }
     table_data += '</tr>';
    }
    table_data += '</table>';
    $('#employee_table').html(table_data);
   }
  });   
 }); 
});

CSS 

div#loadbutton {
    margin-left: 158px;
}
h1#Heading {
    margin-left: 154px;
}
td { 
    border: 1px solid black; 
    word-wrap: break-word; 
} 
input#myInput {
    width: 343px;
    height: 49px;
    border-radius: 21px;
}
.table-responsive {
    min-height: .01%;
    overflow-x: auto;
    WIDTH: 223%;
    MARGIN-LEFT: -205PX;
}
.badge-Nill{
  display: inline-block;
    min-width: 49px;
    padding: 9px 9px;
    font-size: 12px;
    font-weight: 700;
    line-height: 1;
    color: #fff;
    text-align: center;
    white-space: nowrap;
    vertical-align: middle;
    background-color: blue;
    border-radius: 10px;
    width: 127px;
}
.badge-danger {
    display: inline-block;
    min-width: 49px;
    padding: 9px 9px;
    font-size: 12px;
    font-weight: 700;
    line-height: 1;
    color: #fff;
    text-align: center;
    white-space: nowrap;
    vertical-align: middle;
    background-color: red;
    border-radius: 10px;
    width: 127px;
    
}
th {
    text-align: left;
    width: 152px;
}
table {border-collapse:collapse; table-layout:fixed; width:310px;}
table td {border:solid 1px #fab; width:100px; word-wrap:break-word;}
.badge-complete {
    display: inline-block;
    min-width: 49px;
    padding: 9px 9px;
    font-size: 12px;
    font-weight: 700;
    line-height: 1;
    color: #fff;
    text-align: center;
    white-space: nowrap;
    vertical-align: middle;
    background-color: limegreen;
    border-radius: 10px;
    width: 127px;
}
div#employee_table {
    margin-left: 170px;
    margin-right: 70px;
}

所以它过滤值，在这里我想使用Value和color过滤表。例如，如果我键入 ABS 和 RED ，则应检索值为 ABS 和颜色 Red 的列。 。有什么办法吗？

解决方法

顺便说一句，您还可以添加您的AJAX样本数据，这将成为真实的Minimal,Reproducible Example ，这样，我将仅以赢得的HTML表为例。

您要将<span class="badge-danger">和badge-complete类的跨度添加到td中，因此只需搜索innerHTML而不是textContent或innerText这些类名的td's或整个tr。

为了能够搜索“颜色”，请获取输入值，如果它与red相匹配，请将其切换为badge-danger并进行搜索。绿色也一样：

  if (filter === "RED") {
    filter = "badge-danger";
  } else if (filter === "GREEN") {
    filter = "badge-complete";
  }

这是搜索列的方式，在下面的示例中，这将搜索前3列：

  for (var i = 0; i < rows.length; i++) {
    var Col1 = rows[i].cells[0].innerHTML;
    var Col2 = rows[i].cells[1].innerHTML;
    var Col3 = rows[i].cells[2].innerHTML;
    if (Col1.indexOf(filter) > -1 ||
      Col2.indexOf(filter) > -1 ||
      Col3.indexOf(filter) > -1) {
      rows[i].style.display = "";
    } else {
      rows[i].style.display = "none";
    }
  }

因此，从这样发布的图片来看，您需要定位最后4列：

    for (var i = 0; i < rows.length; i++) {
    var Col1 = rows[i].cells[4].innerHTML;
    var Col2 = rows[i].cells[5].innerHTML;
    var Col3 = rows[i].cells[6].innerHTML;
    var Col4 = rows[i].cells[7].innerHTML;
    if (Col1.indexOf(filter) > -1 ||
      Col2.indexOf(filter) > -1 ||
      Col3.indexOf(filter) > -1 ||
      Col4.indexOf(filter) > -1 ) {
      rows[i].style.display = "";
    } else {
      rows[i].style.display = "none";
    }
  }

仅颜色示例： 

function filterTable(event) {
  var filter = document.getElementById("myInput").value.toUpperCase();
  var rows = document.querySelector("#myTable tbody").rows;

  if (filter === "RED") {
    filter = "badge-danger";
  } else if (filter === "GREEN") {
    filter = "badge-complete";
  }

  for (var i = 0; i < rows.length; i++) {
    var Col1 = rows[i].cells[0].innerHTML;
    var Col2 = rows[i].cells[1].innerHTML;
    var Col3 = rows[i].cells[2].innerHTML;
    if (Col1.indexOf(filter) > -1 ||
      Col2.indexOf(filter) > -1 ||
      Col3.indexOf(filter) > -1) {
      rows[i].style.display = "";
    } else {
      rows[i].style.display = "none";
    }
  }
}

document.querySelector('#myInput').addEventListener('keyup',filterTable,false);
div#loadbutton {
  margin-left: 158px;

}

  border-radius: 10px;

}

div#employee_table {
  margin-left: 170px;
  margin-right: 70px;
}
<input type="text" id="myInput" name="myInput" onkeyup="filterTable()" placeholder="color"><br>

<table id="myTable">
  <thead>
    <tr>
      <th>First Name</th>
      <th>Last Name</th>
      <th>Points</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td><span class="badge-danger">Jill</span></td>
      <td>Smith</td>
      <td>50</td>
    </tr>
    <tr>
      <td>Eve</td>
      <td>Jackson</td>
      <td><span class="badge-danger">94</span></td>
    </tr>
    <tr>
      <td>Adam</td>
      <td><span class="badge-danger">Johnson</span></td>
      <td>67</td>
    </tr>
    <tr>
      <td>Bo</td>
      <td><span class="badge-complete">Nilson</span></td>
      <td>35</td>
    </tr>
  </tbody>
</table>

组合： 要将其结合起来，还需要做更多的工作：

当您搜索名称时，它会过滤这些名称，但是当您在搜索颜色的顶部时，它将找到所有与名称无关的颜色，因此您需要说只搜索那些尚未隐藏的行： 

if (tr[i].style.display !== "none") {
  tr[i].style.display = "";
}

您还必须调整以下颜色：

if (filter === "RED" || filter === "R" || filter === "RE") {
    filter = "badge-danger";
  }

因为如果只留下红色字样，当您键入后面的r时，它将全部隐藏，并且我们有条件仅搜索未隐藏的字样，因为只有红色字样会转换为徽章危险。在文本上，您不需要。或使用颜色名称进行下拉...

这是在清空一个输入时全部重置：

if (filter==="") {
document.getElementById("myInput").value="";
document.getElementById("myInputtext").value="";
[...document.querySelectorAll("#myTable tbody tr")].forEach(el => { el.style.display = "" });
}

合并示例： 搜索adam或bo，green或red ... 

function myFunction() {
  // Declare variables
  var input,filter,table,tr,td,i,txtValue;
  input = document.getElementById("myInputtext");
  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")[0];
    if (td) {
      txtValue = td.textContent || td.innerText;
      if (txtValue.toUpperCase().indexOf(filter) > -1) {
        if (tr[i].style.display !== "none") {
          tr[i].style.display = "";
        }
      } else {
        tr[i].style.display = "none";
      }
    }
  }
  
if (filter==="") {
document.getElementById("myInput").value="";
document.getElementById("myInputtext").value="";
[...document.querySelectorAll("#myTable tbody tr")].forEach(el => { el.style.display = "" });
}
}





function filterTable(event) {
  var filter = document.getElementById("myInput").value.toUpperCase();
  var rows = document.querySelector("#myTable tbody").rows;

  if (filter === "RED" || filter === "R" || filter === "RE") {
    filter = "badge-danger";
  } else if (filter === "GREEN" || filter === "G" || filter === "GR" || filter === "GRE" || filter === "GREE") {
    filter = "badge-complete";
  }

  for (var i = 0; i < rows.length; i++) {
    var Col1 = rows[i].cells[0].innerHTML;
    var Col2 = rows[i].cells[1].innerHTML;
    var Col3 = rows[i].cells[2].innerHTML;
    if (Col1.indexOf(filter) > -1 ||
      Col2.indexOf(filter) > -1 ||
      Col3.indexOf(filter) > -1) {
      if (rows[i].style.display !== "none") {
        rows[i].style.display = "";
      }
    } else {
      rows[i].style.display = "none";
    }
  }

肯定还有改进的空间，但是我为此花了很多时间，这足以让您开始并理解如何做。
