Send object from node.js to ejs, not [object Object]

问题

If you use node.js and ejs and render JavaScript object to ejs, the resultant HTML page has the following syntax:

[object Object]

despite the fact that my object is as follows:

[{"a": 3, "b": 10}, {"c":3, "d":20}, {"e":1, "f":55}]

However, I want to render the object itself (object literal if I understand it correctly), not the useless [object Object].

So how can I render it properly? res.render("index", {result: listOfObject.valueOf()}) didn't work.

回答1:

[object Object] is what you get when you call .toString() on an anonymous object. This is implicitly done when you concatenate with another string (e.g. "my object: " + {a:'b'}).

If you want to get the output you're looking for, you need to use

JSON.stringify(yourObjectHere)

Which prints it all out nicely.

回答2:

res.render("index", { result: JSON.stringify(listOfObject) });
