I am using the jquery validation plugin for form validation. Using the min
property works fine, but I want it to validate values strictly greater than that min value.
我正在使用jquery验证插件进行表单验证。使用min属性工作正常,但我希望它验证严格大于该最小值的值。
rules: {
price: {
required: true,
min: 13,
number: true
}
}
In my code I have min: 13
, but I don't want to allow 13, only values greater than 13, e.g. 13.10, 13.20, 14. How can I do this?
在我的代码中我有min:13,但我不想允许13,只有大于13的值,例如13.10,13.20,14。我该怎么做?
Thanks in advance !
提前致谢 !

Create your own custom method with $.validator.addMethod
:
使用$ .validator.addMethod创建自己的自定义方法:
$.validator.addMethod('minStrict', function (value, el, param) {
return value > param;
});
Then use:
price: {
required: true,
minStrict: 13,
number: true
}
Note: The creators of the validator plugin recommend adding Number.MIN_VALUE
to the value you supply:
注意:验证器插件的创建者建议将Number.MIN_VALUE添加到您提供的值:
min: 13 + Number.MIN_VALUE
Number.MIN_VALUE
is the smallest positive (non-zero) float that JS can handle, hence the logic is that the two statements below are equivalent:
Number.MIN_VALUE是JS可以处理的最小正(非零)浮点数,因此逻辑是下面的两个语句是等价的:
a > b;
a >= b + Number.MIN_VALUE;
But, this doesn't work, due to the way floating-point numbers are stored in memory. Rounding will cause b + Number.MIN_VALUE
to equal b
in most cases (b
must be very small for this to work).
但是,由于浮点数存储在内存中的方式,这不起作用。在大多数情况下,舍入将导致b + Number.MIN_VALUE等于b(b必须非常小才能使其工作)。

min: 13.01, this:
min:13.01,这个:
rules:{ price:{ required: true, min: 13.01, number: true } }
规则:{price:{required:true,min:13.01,number:true}}
