JavaScript 代码优化：将数组元素拼接成字符串并发送 AJAX 请求

$(function() { var daanArray = [];

$('.xuanze').click(function(e) { $(this).toggleClass('redBorder');

var id = $(this).attr('i');
var daan = $(this).attr('value');
daanArray.push(daan);

var daanString = daanArray.join(''); // 将daanArray的元素以字符串形式拼接在一起

console.log(daanString);

$.ajax({
  type: 'POST',
  url: '{:url("Dati/getAnswer")}',
  data: { daan: daanString }, // 将拼接后的字符串作为daan的值
  dataType: 'json',
  success: function(msg) {
    console.log('成功');
  }
});

}); });
