如何随意将课程添加到＆＃34; td＆＃34;与Jquery的表？

Question

我正在尝试建立一个座位预订应用程序。

我有一张HTML表格，如下图所示。

HTML代码

<table class="responsive-table bordered booking-table">

                </table>  

我有座位号，由用户预订并随机存储为数组。

e.g

var booked_seats = ["A2", "A6", "B7", "B8", "B12", "D1", "D7", "D8"];    

我想要做的是我想突出显示表格的 td 框。

例如，如果数组数据包含座位号 A2 ，则会突出显示带有名为＆＃34的类的 A2 框;突出显示＆＃34;。< / p>

例如像这样的

if (array_data_number == booking_table_number){
   $('table>tbody>tr>td').addClass('highlight'); 
}

如何使用Jquery实现它？

Answer 1

一个简单的点击事件就可以了。

$("td").click(function(){
   $(this).addClass("highlight")
});

或预先从数组中选择

var booked_seats = ["A2", "A6", "B7", "B8", "B12", "D1", "D7", "D8"];   

$(".bordered").find("td").each(function(){

   if(booked_seats.indexOf($(this).text()) > -1)
   {
       $(this).addClass("highlight");
   }
}

Answer 2

//find all the td
$('.booking-table td').filter(function(){
  //return those that have their text in the booked seats
  return booked_seats.indexOf(this.innerHTML) > -1;
}).addClass('highlight'); //add the class to all the tds matched
