在 node/express + ejs 中将对象传递给客户端? [英] Passing an object to client in node/express + ejs?

问题描述

我有一个非常大的对象，我需要将它传递给客户端脚本中的一个函数.我曾尝试使用 JSON.stringify，但在使用这种方法时遇到了一些问题 - 主要与性能有关.有没有可能在 ejs 中做这样的事情?

I have a pretty large object that I need to pass to a function in a client script. I have tried using JSON.stringify, but have run into a few issues with this approach - mostly performance related. Is it possible to do something like this in ejs?

app.get('/load', function(req, res) {
    var data = {
        layout:'interview/load',
        locals: {
            interview: '',
            data: someLargeObj
        }
    };
    res.render('load', data);
});

在我的客户端脚本中，我会将这个对象传递给这样的函数

And in my client script, I would pass this object to a function like so

<script type="text/javascript">
    load(<%- data %>); // load is a function in a client script
</script>

当我尝试这个时，我得到了

When I try this I get either

<script type="text/javascript">
    load();
</script>

或

<script type="text/javascript">
    load([Object object]);
</script>

推荐答案

这是预期的行为.您的模板引擎正在尝试从您的对象创建一个指向 [Object object] 的字符串.如果你真的想传递这样的数据，我认为你通过字符串化对象做了正确的事情.

That is the expected behavior. Your template engine is trying to create a string from your object which leads to [Object object]. If you really want to pass data like that I think you did the correct thing by stringifying the object.
