javascript - 突出显示文本并更改颜色

Question

那里

所以基本上我是编程新手，我正在做一些事情，你有一个 html 表格，我正在使用 jquery 检查某个字段是否有数字，如果有，那么该行会突出显示。现在我有了可以工作的代码，但问题是我希望它以红色突出显示背景并将文本颜色更改为白色，这也可以，但我的表格有超链接，尽管我的代码仍然保持蓝色，所以任何人都可以改进我的代码？

我希望所有文本都变成白色，包括带有“href”的链接

$(document).ready(function() {
  
  var levelColumnIndex = 5;
  $('tr td:nth-child('+levelColumnIndex+')').each(function() {
    var cellText = $(this).html(); 
    if(cellText == 3){
    		  $(this).parent().css('background-color','red');
          $(this).parent().css('color','white');

    } 
	});
});

Answer 1

在代码中找到a标签并使用css给它上色

$(document).ready(function() {
  
  var levelColumnIndex = 5;
  $('tr td:nth-child('+levelColumnIndex+')').each(function() {
    var cellText = $(this).html(); 
    if(cellText == 3){
    		  $(this).parent().css('background-color','red');
              $(this).parent().css('color','white');
              $(this).parent().find('a').css('color','white');

    } 
	});
});
