另一個jquery驗證問題

Question

我想驗證一個名爲promoRent的字段，如果只有輸入的數字。這不是必填字段，但是如果輸入它必須大於lotRent。我有：

jQuery.validator.addMethod("PRgreaterThanLotRent", function(value, element) { 
    return parseFloat($("#lotRent").val().replace(/[^\d\.]/g, '').replace(['.00'],''))  < parseFloat($("#promoRent").val().replace(/[^\d\.]/g, '').replace(['.00'],'')); 
}); 


    $("#pricingForm").validate({ 
    rules: { salesPrice: "required", 
    Rent: { required: true, greaterThanLotRent : true }, 
    promoRent : { required: function() { if ($("#promoRent").val() != '') { PRgreaterThanLotRent : true }; } } 
}, 
    messages: { salesPrice: "<br/><span style='color:red'>Required!</span>", 
    mhRent: { required: "<br/><span style='color:red'>Required!</span>", 
     MHgreaterThanLotRent : "<br/><span style='color:red; '>Must be greater<br> than Lot Rent</span>" } , 
    promoRent : { required: "", 
     PRgreaterThanLotRent : "<br/><span style='color:red; '>Must be greater<br> than Lot Rent</span>" } 
} 
}).form(); 

我做一些愚蠢的驗證，即使我進入量小於該lotrent不運行。有任何想法嗎？提前致謝。

這個很好用。

,promoRent : { PRgreaterThanLotRent : true } 

然後修改PRgreaterThanLotRent功能如下：

jQuery.validator.addMethod("PRgreaterThanLotRent", function(value, element) { 
     if ($("#promoRent").val() != '') {             
     return parseFloat($("#lotRent").val().replace(/[^\d\.]/g, '').replace(['.00'],'')) < parseFloat($("#promoRent").val().replace(/[^\d\.]/g, '').replace(['.00'],'')); 
     } else { 
     return true; 
     } 
    }); 

sweeeeeeet ...
