淘汰赛js和全球化 [英] knockout js and globalization

问题描述

我无法弄清楚如何处理利用基因敲除JS和非美国地区的计算。我的逗号，并使用jquery.globalization插件验证正确，但淘汰赛计算给了我一个非数字。是否淘汰赛JS支持这种以任何方式或是否存在任何变通办法？

I can't figure out how to handle calculations using knockout js and a non us locale. My comma is , and is validated correctly using the jquery.globalization plugin but the knockout calculation is giving me a NaN. Does knockout js support this in any way or does it exist any workarounds?

示例：

请在淘汰赛JS现场工作允许十进制值的数量字段，允许输入的全球化（如逗号符号）和输出格式的cartEditor例如

Make the cartEditor example on the knockout js site work allowing decimal values in the quantity field and allowing globalized input (, as comma sign) and output formatting

<一个href=\"http://knockoutjs.com/examples/cartEditor.html\">http://knockoutjs.com/examples/cartEditor.html

我需要这一个asp.net MVC 3网站的工作，因为我使用的是NB-NO文化和模型绑定期待运行网站，逗号标志

I need this to work on a asp.net mvc 3 site because I am running the site using the nb-NO culture and the model binder is expecting , as the comma sign

推荐答案

我做了这样的事情，写入一个包裹 autoNumeric自定义绑定。 JS 的格式。 （要点）

I did something like this by writing a custom binding that wrapped autoNumeric.js for the formatting. (gist)

ko.bindingHandlers.autoNumeric = function ($) {

    function getElementValue(el) {
        return parseFloat(el.autoNumericGet(), 10);
    }

    function getModelValue(accessor) {
        return parseFloat(ko.utils.unwrapObservable(accessor()), 10);
    }

    return {
        init: function (el, valueAccessor, bindingsAccessor, viewModel) {
            var $el = $(el),
                bindings = bindingsAccessor(),
                settings = bindings.settings,
                value = valueAccessor();

            function updateModelValue() {
                value(getElementValue($el));
            };

            $el.autoNumeric(settings);
            $el.autoNumericSet(getModelValue(value), settings);
            $el.change(updateModelValue);
        },
        update: function (el, valueAccessor, bindingsAccessor, viewModel) {
            var $el = $(el),
                newValue = getModelValue(valueAccessor()),
                elementValue = getElementValue($el),
                valueHasChanged = (newValue != elementValue);

            if ((newValue === 0) && (elementValue !== 0) && (elementValue !== "0")) {
                valueHasChanged = true;
            }

            if (valueHasChanged) {
                $el.autoNumericSet(newValue);
                setTimeout(function () { $el.change() }, 0);
            }
        }
    };
}

数据使用这个自定义autoNumeric结合看起来像这样绑定：

the data binding using this custom autoNumeric binding looks like this:

<input data-bind="autoNumeric:amount, settings:{aSign:'$'}" />

查看autoNumeric.js多种选项，可以格式化，看看你能做些什么ewith的设置。
