带有jquery验证和Html.EditorFor和不同的小数分隔符的asp.net mvc [英] asp.net mvc with jquery validation and Html.EditorFor and different decimalseparators

问题描述

我已经阅读了很多有关此主题的博客文章，但是我从未看到完整的解决方案.

I've read a lot of blogposts about this subject, but I never saw the complete solution.

我已经使用了默认的html(其中bedrag是一个十进制):

I've scaffolfed this default html (where bedrag is a Decimal):

<div class="editor-field">
            @Html.EditorFor(model => model.Bedrag)
            @Html.ValidationMessageFor(model => model.Bedrag)
        </div>

呈现页面时，即使在我将其放在web.config中时，这也会在输入控件中为小数点生成一个逗号: <globalization culture="en-US" uiCulture="en-US" />或这个 <globalization culture="auto" uiCulture="auto" />

This generates a comma for the decimal in the input control when the page is rendered, even when I put this in my web.config: <globalization culture="en-US" uiCulture="en-US" /> or this one <globalization culture="auto" uiCulture="auto" />

然后，Jquery Validation插件抱怨我在'bedrag'输入字段(已由@Html.EditorFor(model => model.Bedrag)放在该字段中)中用逗号作为小数点分隔符，这给我输入的内容不是数字提供了错误；它希望以点作为小数点分隔符.

Then, the Jquery Validation plugin complains that I have a comma as decimal separator in my 'bedrag' input field (which has been put there by the @Html.EditorFor(model => model.Bedrag)), which gives the error my input is not a number; it expects a dot as a decimal separator.

但是，当我输入此数字12.90时，默认的modelbinder会将我的输入转换为1290(输入乘以100).

But, when I enter the number as this 12.90, the defaults modelbinder converts my input to 1290 (input times 100).

然后我创建了一个自定义modelbinder，在该代码中，当前区域性是'nl-NL'，而不是我的web.config中的'en-US'.

Then I created a custom modelbinder, and in that code, the currentculture is 'nl-NL', so not the 'en-US' from my web.config.

所以现在我想知道:

1 2014年我仍然需要自定义模型活页夹吗?

1 Do I still need a custom model binder in 2014?

2 ASP.Net为@Html.ValidationMessageFor(model => model.Bedrag)创建值时使用哪种文化? (为什么不从我的web.config中选择一个?)

2 Which culture is used when ASP.Net creates the value for @Html.ValidationMessageFor(model => model.Bedrag)? (and why not the one from my web.config?)

3如何动态设置要用于@Html.ValidationMessageFor(model => model.Bedrag)

3 How can I dynamicly set the culture to use for the @Html.ValidationMessageFor(model => model.Bedrag)

4如何动态设置用于Jquery验证的区域性?

4 How can I dynamicly set the culture to use for the Jquery validation?

我已经退出ASP.Net MVC一年了，但是在2014年，我仍然会遇到这些带有小数点的问题吗?

I've been out of ASP.Net MVC for a year, but can it be that in 2014 I still have these issues with decimal signs?

推荐答案

我使用的方法是扩展jQuery验证程序.它基于此博客文章.我将元数据中的区域性设置为BE-nl.由于这是一个纯荷兰语的网站，因此我不再做任何检查.

The approach I used is to extend the jQuery validator. It is based on this blogpost. I setted the culture in the metadata to BE-nl. Since this is a pure Dutch website, I don't do any checks further on.

$(function () {
    // Look in metatag what culture we want
    // and set this as culture for the client side.
    var data = $("meta[name='accept-language']").attr("content");
    Globalize.culture(data.toString());

    // Don't validate on keyup event because it will mess up
    // the cursor when replacing values in a textbox.
    $('form').each(function () {
        var validator = $(this).data('validator');
        if (validator) {
            validator.settings.onkeyup = false;
        }
    });

    // Belgianize/sanitize the numbers inserted
    // 1 000 000    =>      1000000
    // 1.00         =>      1,00
    $.validator.methods.number = function (value, element) {
        var s = value.replace(/\ /g, '').split('.').join(',');

        if (s.split(',').length < 3) {
            var number = Globalize.parseFloat(s);
            if (!isNaN(number)) {
                $(element).val(s);
                return this.optional(element) || true;
            }
        }

        return this.optional(element) || false;
    };
});

我认为我使用此jQuery库进行了全球化

I think I used this jQuery library for the globalization
