当我从两个下拉菜单中选择“独家交易者”选项和“£ 0 k- £ 85 k”选项并选择“是”单选按钮时-得到正确答案，即£ 700
但在此之后，我再次上升并更改下拉选项（更改为合作伙伴关系），然后div AccountsQuote中的值需要自动更新，即900英镑
但它不是更新-需要做是-否选择来更新值。
我需要根据我的输入自动更改它，即使更改后

以下是我的代码：

$("#businesstype").change(function() {
  callmethod();
});

$("#turnover").change(function() {
  callmethod();
});

function callmethod() {
  $('input[type=radio][name=accounts]').change(function() {
    if (this.value == 'Yes') {

      var businesstype = $('#businesstype').val();
      var turnover = $('#turnover').val();

      if (businesstype == "Sole trader" && turnover == "£ 0k – £ 85k") {
        document.getElementById("AccountsQuote").innerHTML = '£ 700';
      } else if (businesstype == "Sole trader" && turnover == "£ 85k – £ 99k") {
        document.getElementById("AccountsQuote").innerHTML = '£ 850';
      } else if (businesstype == "Partnership" && turnover == "£ 0k – £ 85k") {
        document.getElementById("AccountsQuote").innerHTML = '£ 900';
      }
    } else if (this.value == 'No') {
      document.getElementById("c").innerHTML = '£ 0';
    }
  });
}
