MVC 3不显眼的验证 - 有条件地禁用/启用验证 [英] MVC 3 unobtrusive validation - conditionally disable/enable validation

问题描述

我有有一个选项，输入尺寸的形式：

I have a form that has an option to enter dimensions for:

• 宽度放大器;身高


• 宽度


• 高度

和我有两个div容器，我隐藏/显示，这取决于三个选项中选择：

And I have two container divs that I hide/show depending on which of the three options is selected:

<div class="editor-field" id="width-container">
     @Html.EditorFor(model => model.Width)
     @Html.ValidationMessageFor(model => model.Width)
</div>

<div class="editor-field" id="height-container">
     @Html.EditorFor(model => model.Height)
     @Html.ValidationMessageFor(model => model.Height)
</div>

如果选择的高度，那么宽度没有在表格上显示，我怎么能禁止在时尚的宽输入字段不显眼的审定，让我轻松地复权如果用户改变他们的主意，即去除数据 - *属性是不是一种选择。我很高兴能创建一个CustomAttribute类来处理这个问题，但我不希望有破解标准的jQuery文件，使这项工作，因为它使更新到新版本头疼下降的轨道。如果一切都失败，我将使用添加值为0到田间地头时，他们是不可见的，然后取出显示时，他们是我惯用的伎俩。

If height is selected, then width is not displayed on the form, how can I disable the unobtrusive validation on the Width input field in a fashion that will allow me to easily re-instate it if the user changes their mind i.e. removing data-* attributes is not an option. I'm happy to create an CustomAttribute class to handle this BUT I do not want to have to hack the standard jquery files to make this work as it makes updating to new versions a headache down the track. If all else fails I'll use my usual trick of adding a value of 0 to the fields when they are not visible and then removing it when they are shown.

编辑：

请铭记，当宽度不可见它不是一个隐藏的领域本身，它只是一个输入变量，因为父div有显示器的风格，这不是对用户可见：无

Please be mindful that when Width is not visible it is not a "hidden" field per se it's just a input tag that's not visible to the user because the parent div has a style of display:none

推荐答案

您可以设置jQuery的验证程序的处理您的不显眼的验证，忽略隐藏元素：

You can set up the jQuery validator that's processing your unobtrusive validation to ignore hidden elements:

jQuery.validator.defaults.ignore = ":hidden";

// the line above is outside any $(document).ready(...) or similar
$(document).ready(function(){
    ...
});
...
