How to change the maxlength of a textbox using jQuery Validation based on a condition.

代码

如何根据if-else条件更改最大长度?

How do I change the maxlength based on an if-else condition?

推荐答案

三元表达式是否是您想要的?

Would a ternary expression be what you want ?

SSN: { required: true, minlength: 9, maxlength: ((condition)?true:false) }

示例:

SSN: { required: true, minlength: 9, maxlength: ((my_var=="short")?13:17) }

如果满足条件，将打印13，否则打印17

Would print 13 if the condition is met, otherwise 17

校正最大长度，使其大于最小长度.

Correcting the max lenght so it is bigger than the min lenght.
