如何在條件

Question

使用jQuery Validation plugin，以確保在第二個文本字段什麼用戶輸入的積極cost_of_car在第一個文本字段，並積極支付金額禁用自定義的驗證方法，例如什麼* cost_of_car * 0.4 < =支付金額< = 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 
     } 
    } 
}); 

現在我想跳過testMaxAmount和testMinAmount檢查，直到cost_of_car是有效的。測試

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

甚至

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

這些方法裏面導致遞歸和掛起的瀏覽器。

你提出一些其他方法來禁用支付金額的驗證，直到cost_of_car是有效的嗎？

UPDATE：的改變必須是在validator.addMethod()電話：

$.validator.addMethod("testMaxAmount", function() 
{ 
    if($("#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");
