帶按鈕的jQuery表列過濾器

Question

我有一個HTML表格，當按下按鈕時，該表格應該從下拉列表中選定的值進行過濾。我使用jQuery選擇器「#table_id td。[td class]：contains」和「#table_id td。[td class]：not（：contains）」。一切看起來都不錯，但是：not（：contains）選擇器返回「Syntax error，unrecognized expression」。它在其他例子中以相同的方式工作，但由於某種原因無法使其工作。

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

<select id="selector1"><option value="all">All</option><option value="

我會用.siblings()選擇所有無效的元素，然後調用.hide()而不是:not(:contains())，因爲它是更直觀，更會減少重複的代碼。

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

<select id="selector1"><option value="all">All</option><option value="
