Question

我使用jQuery Validation plugin来确保用户在第一个文本字段中输入正 cost_of_car ，在第二个文本字段中输入正 payment_amount ，例如* cost_of_car * 0.4＆lt ; = payment_amount＆lt; = cost_of_car *：

$.validator.addMethod("testMaxAmount", function()
{
    return $("#cost_of_car").val() - 0 >= $("#payment_amount").val() - 0;
}, "Can't be more than cost_of_car");

$.validator.addMethod("testMinAmount", function()
{
    return $("#cost_of_car").val() * 0.4 <= $("#payment_amount").val() - 0;
}, "Can't be less than cost_of_car * 0.4");

$("#calc_form").validate(
{
    rules: 
    {
        cost_of_car: 
        {
            required: true,
            number: true,
            min: 1,
            max: 10000000
        },
        payment_amount: 
        {
            required: true,
            number: true,
            testMaxAmount: true,
            testMinAmount: true 
        }
    }
});

现在我想跳过testMaxAmount和testMinAmount检查，直到 cost_of_car 有效。测试

$("#calc_form").validate().element("#cost_of_car")

甚至

$("#calc_form").validate({ignore: "#payment_amount"}).element("#cost_of_car")

在这些方法中导致递归并挂起浏览器。

在 cost_of_car 有效之前，您是否会提出其他方法来禁用 payment_amount 的验证？

更新：更改必须在validator.addMethod()来电中：

$.validator.addMethod("testMaxAmount", function()
{
    if($("#cost_of_car").valid())
      return $("#cost_of_car").val() - 0 >= $("#payment_amount").val() - 0;
    else
      return true;
}, "Can't be more than cost_of_car");

$.validator.addMethod("testMinAmount", function()
{
    if($("#cost_of_car").valid())
      return $("#cost_of_car").val() * 0.4 <= $("#payment_amount").val() - 0;
    else
      return true;
}, "Can't be less than cost_of_car * 0.4");

如何在条件下禁用自定义验证方法
