javascript - 带按钮的 jQuery 表列过滤器

Question

我有一个 HTML 表格，按下按钮时应通过下拉列表中的选定值进行过滤。

我使用 jQuery 选择器 #table_id td.[td class]:contains 和 #table_id td.[td class]:not(:contains)。一切看起来都很好，但 :not(:contains) 选择器返回“语法错误，无法识别的表达式”。它在其他示例中以相同的方式工作，但由于某种原因无法使其工作。

$(function() {    
    $('#butt1').click(function() { 
        $("#tast td.col1:contains('" + $('#selector1').val() + "')").parent().show();
        $("#tast td.col1:not(:contains('" + $('#selector1').val() + "'))").parent().hide();
    });
    
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.0/jquery.min.js"></script>    
<select id="selector1"><option value="all">All</option><option value="
Sample 1

我将使用 .siblings() 选择所有无效元素，然后调用 .hide() 而不是 :not(:contains() )，因为它更直观，并且会减少重复代码。

$(function() {    
    $('#butt1').click(function() { 
        $("#tast td.col1:contains('" + $('#selector1').val() + "')").parent().show().siblings().hide();
    });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.0/jquery.min.js"></script>    
<select id="selector1"><option value="all">All</option><option value="
Sample 1
">
Sample 1
</option></select>
<button id="butt1">
