带按钮的jQuery表列过滤器

Question

我有一个HTML表格，当按下按钮时，该表格应该从下拉列表中选定的值进行过滤。我使用jQuery选择器“#table_id td。[td class]：contains”和“#table_id td。[td class]：not（：contains）”。一切看起来都不错，但是：not（：contains）选择器返回“Syntax error，unrecognized expression”。它在其他例子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(); 
 
    }); 
 
    
 
});

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

Answer 1

我会用.siblings()选择所有无效的元素，然后调用.hide()而不是:not(:contains())，因为它是更直观，更会减少重复的代码。

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

<select id="selector1"><option value="all">All</option><option value=" 
 
Sample 1
