Is it simply because you are not wrapping your output in quotes?
仅仅是因为您没有将输出括在引号中吗？
var variable = '{{{reference}}}';

更新：
The actual answer to solve the question was adding |raw to the tag as per comments
解决问题的实际答案是根据评论将 |raw 添加到标签中
var packageDetails = {{(packageDetails|json_encode|raw)}};

You can add the options in the following way:
您可以通过以下方式添加选项：
{{ data|json_encode(constant('JSON_PRETTY_PRINT'))|raw }}
Adding this because it answers the question in your title, but it sounds like the raw filter was really what you were looking for. Still, others may find this useful.
添加这个是因为它回答了你标题中的问题，但听起来原始过滤器确实是你想要的。尽管如此，其他人可能会发现这很有用。
