jquery validate:多个输入值的总和

$(document).ready(function() {
  // 定义自定义验证规则
  $.validator.addMethod("sum", function(value, element, params) {
    // 获取所有输入框的值
    var sum = 0;
    $("input[name='input_name']").each(function() {
      sum += parseInt($(this).val(), 10);
    });
    // 检查总和是否满足条件
    return this.optional(element) || sum >= params[0];
  }, "The sum of the input values must be greater than or equal to {0}.");

  // 初始化表单验证
  $("#myform").validate({
    rules: {
      input_name: {
        required: true,
        sum: [10] // 设置总和的最小值为 10
      }
    },
    messages: {
      input_name: {
        required: "Please enter a value.",
        sum: "The sum of the input values must be greater than or equal to 10."
      }
    },
    submitHandler: function(form) {
      form.submit();
    }
  });
});
