如何在Javascript [在Django模板中]阅读Python列表 [英] How to read Python list in Javascript [in a Django template]

问题描述

我在oTree编程（这是一个基于Django的社交实验环境），我有以下问题。我在Python中定义了一些列表，我想导入它们并在HTML模板中使用它们。如果我用HTML打印它我会设法看到它们没有任何问题，但是，一旦我需要在Javascript中使用它们，程序就无法读取它们并且列表元素的单引号在&安培;＃39; 。
列表导入如下 var filtered_elements = {{array}}; 。

I'm programming in oTree (which is a Django based environment for social experiments) and I have the following problem. I defined some lists in Python and I'd like to import them and use them in an HTML template. If I print them in HTML I manage to see them without any problem, however, once I need to use them in Javascript, the program fails to read them and the single quotes of the elements of the list are converted in '. The list is imported like this var filtered_elements = {{ array }};.

我认为问题就在这里，因为JS无法使用它们。你有什么建议怎么做吗？我考虑过使用JSON，但由于我对编程很陌生，我无法理解它是否只是浪费时间或者有更简单的方法。
感谢您的回答！

I think the problem is exactly here, as JS cannot work with them. Do you have any suggestion on how to do that? I considered using JSON, but since I'm quite new to programming, I cannot understand if it's just a waste of time or there is a simpler way out. Thanks for your answers!

推荐答案

听起来您的数据已经是JSON，否则您将获得单引号和 u 前缀。所以唯一的问题是Django autoescaping;您可以使用 safe 过滤器禁用它：

It sounds like your data is already JSON, otherwise you would be getting single quotes and u prefixes. So the only issue is Django autoescaping; you can disable it with the safe filter:

var filtered_elements = {{ array|safe }};
