如何根据下拉列表动态更改jquery验证规则

Question

我有一个产品选择下拉菜单。当有人选择产品时，我会从选择中提取特定的验证数据。但是，如果有人需要在点击“提交”之前更改产品，则需要加载新的验证条件。

我现在具有验证数据作为JS对象。而且我可以在控制台中访问它，选择它后会给我正确的数据。但是，jQuery validate保留第一个选定的信息。

您可以在此处查看示例： http://jsfiddle.net/lz430/689ouzbf/2/

jQuery(document).ready(function($) {
  $("#product-validation input")
    .not(':button, :submit, :reset, :hidden')
    .removeClass('error')
    //.val('')
    .prop('checked', false)
    .prop('selected', false);
  $("label.error").hide();

  var validator,
    DPPSI_1_50_min,
    DPPSI_1_50_max,
    DPPSI_2_40_min,
    DPPSI_2_40_max,
    DPPSI_3_30_min,
    DPPSI_3_30_max,
    DPPSI_4_20_min,
    DPPSI_4_20_max,
    DPPSI_5_10_min,
    DPPSI_5_10_max,
    DPPSI_6_0_min,
    DPPSI_6_0_max,
    ca_1_50_min,
    ca_1_50_max,
    ca_2_40_min,
    ca_2_40_max,
    ca_3_30_min,
    ca_3_30_max,
    ca_4_20_min,
    ca_4_20_max,
    ca_5_10_min,
    ca_5_10_max,
    ca_6_0_min,
    ca_6_0_max,
    messages;

  // Registration username
  var matchtext = $("#input_2_1");
  $("#input_2_5_3").on('change', function() {
    console.log(this.value);
    matchtext.val($(this).val());
  });


  function validData(dataAttr) {
    DPPSI_1_50_min = dataAttr.dppsi_1_50_min;

尽管我不确定为什么它在JSFiddle中不起作用。但是您可以看到，我正在注销对象，并且获得了正确的值。我只需要将这些传递给jquery验证。

任何帮助都将受到赞赏！
