它是更好地使用嵌入的JavaScript或单独的.js文件在MVC3看法？ [英] Is it better to use embedded javascript or a separate .js file in an MVC3 view?

问题描述

有人告诉我说，最好将JavaScript code在一个单独的文件，以保持分离的担忧，虽然这个想法与我产生共鸣，我并不觉得踏实。

I've been told that it's best to place Javascript code in a separate file to keep concerns separated, and while the idea resonates with me, I don't find it practical.

这可能只是我的经验不足，因此这个问题。

That may just be my inexperience, hence this question.

下面是一个明确的例子，我发现，放置code的看法是不是将其放置在一个单独的JavaScript文件更好。

Here's a clear cut example where I found that placing the code in the View was better than placing it in a separate javascript file.

在我看来，我需要调用jQueryUI的对话框，并与我的模型的名称动态设置标题。

In my View, I needed to invoke a JQueryUI dialog, and set the title dynamically with the Name of my model.

$("#thumbs img").click(function () {
    var url = $(this).attr("src");
    $(".image-popup").attr("src", url);

    return $("#image-popup").dialog({
        modal: true,
        closeOnEscape: true,
        minHeight: 384,
        minWidth: 596,
        resizable: false,
        show: {
            effect: 'slide',
            duration: 500,
            direction: 'up'
        },
        hide: {
            effect: 'slide',
            duration: 250,
            direction: 'up'
        },
        title: '@Model.Product.Name'
    });
});

注意：

title: '@Model.Product.Name'

正如你可以看到我有的访问的到，如果我在我看来，使用JavaScript的强类型的模型。这是不是这样，如果我使用一个单独的JavaScript文件。

As you can see I have access to the strongly typed model if I use Javascript in my View. This is not the case if I use a separate Javascript file.

我这样做不对，是有什么事，我没有看到？

Am I doing this wrong, is there something I'm not seeing?

如果我是用一个单独的文件，怎么会看起来像看到，因为我无法从JavaScript内提交访问模型属性？

If I were to use a separate file, how would it look like seeing as I can't access the Model properties from within the Javascript file?

推荐答案

独立的js文件：

<div id="thumbs">
    <img data-dialog-title="@Model.Product.Name" src="[whatever url]" />
</div?

$("#thumbs img").click(function () {
    var title = $(this).data('dialog-title');
    var url = $(this).attr("src");
    $(".image-popup").attr("src", url);

    return $("#image-popup").dialog({
        modal: true,
        closeOnEscape: true,
        minHeight: 384,
        minWidth: 596,
        resizable: false,
        show: {
            effect: 'slide',
            duration: 500,
            direction: 'up'
        },
        hide: {
            effect: 'slide',
            duration: 250,
            direction: 'up'
        },
        title: title
    });
});

使用HTML5数据 - *属性悄悄地通过访问DOM模型属性。上面的JavaScript将完全正常工作作为外部文件。

Access the model properties unobtrusively through the dom using HTML5 data-* attributes. The javascript above will work perfectly fine as an external file.
