Validate for number range using jquery.validate data annotations
提问by Travis J
When constructing an input an ASP.NET MVC 3 view which uses jQuery.validate
构造输入时使用 jQuery.validate 的 ASP.NET MVC 3 视图
<input
type="text"
class="text-box single-line"
id="ReserveQuantity"
name="ReserveQuantity"
data-val="true"
data-val-required="The Reserve Quantity field is required."
data-val-number="This value must be numeric"
>
this is markup that would be used for for a ReserveQuantity input. In addition to these parameters, what data-annotation should I use in order to make sure only a certain numeric range is acceptable here without manual validation?
这是用于 ReserveQuantity 输入的标记。除了这些参数之外，我data-应该使用什么注释来确保这里只有特定的数字范围是可接受的，而无需手动验证？

There is actually a built in data annotation for ranges, and it looks like this:
实际上有一个内置的范围数据注释，它看起来像这样：
data-val-range="The field must be in range 0 to 104."
data-val-range-min="0"
data-val-range-max="104"

var minVal = 10, maxVal = 20;
$("#myform").validate({
rules: {
ReserveQuantity: {
required: true,
range: [ minVal, maxVal ]
}
}
});
