Jquery Keyup 过滤器和输入值问题

Question

我正在使用 jquery 在表中进行搜索。使用键盘搜索有效，但使用按钮过滤不起作用 请点击按钮。

我希望在单击按钮时将其添加到输入和搜索

示例：

/* Searching with keyboard */
$(document).ready(function(){
  $("#search").on("keyup", function() {
    var value = $(this).val().toLowerCase();
    $("table td").filter(function() {
      $(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
    });
  });
});

/*Searching with button */
$("button").click(function(){
    var id = $(this).attr("data-id");
    $("#search").val(id);
});

table tr td{
  border:1px solid #000;
}

<input type="text" id="search" placeholder="Search"><br>
<button type="button" data-id="????">???? Facebook</button>
<button type="button" data-id="????">???? Facebook</button>
<p>Searching with keyboard is working but filtering with button does not work. <br>Please click to button.</p>
<table>
    <thead>
        <tr>
            <td>Hood 1</td>
            <td>Hood 2</td>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>???? Facebook</td>
            <td>???? Facebook</td>
        </tr>
        <tr>
            <td>???? Twitter</td>
            <td>???? Twitter</td>
        </tr>
    </tbody>
</table>

您在单击按钮时缺少搜索键功能的调用

/* Searching with keyboard */
$(document).ready(function(){
  $("#search").on("keyup", function() {
    var value = $(this).val().toLowerCase();
    $("table td").filter(function() {
      $(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
    });
  });
});

/*Searching with button */
$("button").click(function(){
    var id = $(this).attr("data-id");
    $("#search").val(id);
    $('#search').keyup();
    
});

table tr td{
  border:1px solid #000;
}

<input type="text" id="search" placeholder="Search"><br>
<button type="button" data-id="?">? Facebook</button>
<button type="button" data-id="?">? Twitter</button>
<p>Searching with keyboard is working but filtering with button does not work. <br>Please click to button.</p>
<table>
    <thead>
        <tr>
            <td>Hood 1</td>
            <td>Hood 2</td>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>? Facebook</td>
            <td>? Facebook</td>
        </tr>
        <tr>
            <td>? Twitter</td>
            <td>? Twitter</td>
        </tr>
    </tbody>
</table>
