发送像250这样的正确值，尝试获取标签文本

    <label for="fadder-amount_300" class="ui-radio ">300 kr/mån</label>

on select应该是捕获 - 300 kr /mån

Answer 1

要选择与label相关的input文本，请为其附加change事件处理程序并遍历DOM，如下所示：

＆＃13;

$('div#fadder-amount-type-0 input[type=radio]').change(function() {
  var labelText = $(this).nextAll('label').text();
  console.log(labelText);
});

＆＃13;
