$("#date_employed").on("change", function() {

  var selected = this.value;

  if (selected != "All") {
    rows.filter("[name=" + selected + "]").show();

＆lt; / script缺失＆gt;你有}）;很多人：

<script>
$("#date_employed").on("change", function(){
  var selected = this.value;

    if(selected != "All"){
        rows.filter("[name="+selected+"]").show();
        rows.not("[name="+selected+"]").hide();
        var visibleRows = rows.filter("[name="+selected+"]");
    }
    else {
        rows.show();
    }
});  
</script>                                                                                                                       
<button type="button" name="action" id="action" class="btn btn-warning">Add</button>
<select id="date_employed" class="btn btn-danger dropdown-toggle">
  <option value="choose">Filter</option>
  <option value="first_name">First Name</option>
  <option value="last_name">Last Name</option>
</select>

你也可以这样做：

var selected = $(this).val();

你能帮我这个功能吗？
