use thisreference
使用this参考
$("button").click(function(){
$(this).parents('tr').find(".b1").load("content.txt");
$(this).parents('tr').find(".b2").load("content1.txt");
});
or
或者
$("button").click(function(){
$(this).parent().siblings(".b1").load("content.txt");
$(this).parent().siblings(".b2").load("content1.txt");
});

$(".b1")and $(".b2")are selecting every element with that class. You need to filter based on the row the button is in using something like this:
$(".b1")并且$(".b2")正在选择具有该类的每个元素。您需要根据按钮所在的行使用以下内容进行过滤：
$("button").click(function(){
var $row = $(this).closest("tr");
$row.find(".b1").load("content.txt");
$row.find(".b2").load("content1.txt");
});
