Node.js:如何将Node.js嵌入HTML? [英] Node.js : How to embed Node.js into HTML?

问题描述

在php文件中，我可以执行以下操作:

<p><?php echo "hello!";?></p>

是否可以在节点中执行此操作，如果可以，那么逻辑是什么?

Is there a way to do this in node, if yes what's the logic for it?

我知道如何完成此操作:

• 为HTML文件中的节点使用标识符标记，例如:<node>code</node>

加载并添加在Node中解析HTML文件

Load & Parse HTML file in Node

Grab节点标记并运行它

Grab node markup from the HTML file and run it

但是我不确定这是否是最好的方法，即使它可行:)

But I'm not sure if this is the best way or even if it works :)

请注意，我想学习node.js，所以express和其他库和模块对我来说不是答案，因为我想了解流程的逻辑.

Please note I want to learn node.js, so express and other libraries and modules are not answers for me, because I want to know the logic of the process.

推荐答案

您描述/要求的node.js预处理程序是什么. 它确实存在，但被认为是有害的.

What your describing / asking for a node.js preprocessor. It does exist but it's considered harmful.

更好的解决方案是使用express中使用的视图.看看截屏.

A better solution would be to use views used in express. Take a look at the screencasts.

如果您必须从头开始做所有事情，则可以编写一个微型模板引擎.

If you must do everything from scratch then you can write a micro templating engine.

function render(_view, data) {
    var view = render.views[view];
    for (var key in data) {
        var value = data[key];
        view.replace("{{" + key + "}}", value);
    }
    return view;
}

render.views = {
    "someView": "<p>{{foo}}</p>"
};

http.createServer(function(req, res) {
    res.end(render("someView", {
        "foo": "bar" 
    }));
});

有充分的理由说明直接将php/asp/js代码与HTML混合是不好的.它不会促进关注点分离，并导致产生意粉代码.这些天的标准方法是像上面的模板模板引擎.

There are good reasons why mixing php/asp/js code directly with HTML is bad. It does not promote seperation of concerns and leads to spaghetti code. The standard method these days is templating engines like the one above.
