[英]Parsing and filtering JSON using Jekyll/Liquid
I try to select and use the sub-tree of my navigation, specified in JSON, in Jekyll. 我尝试在Jekyll中选择并使用JSON中指定的导航子树。
This is the file _data/navigation.json : 这是文件_data / navigation.json :
{
"main": [
{"text": "a", "children" : [
{"text": "aa" },
{"text": "ab" }
]},
{"text": "b", "children": [
{"text": "ba", "children": [
{"text": "baa" },
{"text": "bab" },
{"text": "bac" }
] },
{"text": "bb", "children": [
{"text": "bba" },
{"text": "bbb" },
{"text": "bbc" }
]},
{"text": "bc", "children": [
{"text": "bca"},
{"text": "bcb"}
]},
{"text": "bd" },
{"text": "be" }
]},
{"text": "d" },
{"text": "e"},
{"text": "f" },
{"text": "g" }
]
}
Now I want to get the subtree of 'b': 现在我想得到'b'的子树:
{% assign stuff = site.data.navigation.main | where:"text","b" %}
If I print this via {{ stuff }}
, jekyll/liquids serves me an one line string representation starting {"text": "b", "children":...
, as one could expect. 如果我通过
{{ stuff }}
打印这个,jekyll / liquids为我提供了一个单行字符串表示,从{"text": "b", "children":...
,正如人们所期望的那样。 {{stuff | size}}
{{stuff | size}}
is 1, so I can expect, it is one object, instead a sequence of characters internally. {{stuff | size}}
是1,所以我可以期待,它是一个对象,而不是内部的一系列字符。 But if I want to go on working with this structure, I get no output, stuff.text
, stuff["text"]
and so on does not work. 但是,如果我想继续使用这个结构,我没有输出,
stuff.text
, stuff["text"]
等等不起作用。
Has someone a hint for me? 有人暗示我吗?
If you use {{ stuff | inspect }}
如果你使用
{{ stuff | inspect }}
{{ stuff | inspect }}
you can see that it is an array. {{ stuff | inspect }}
你可以看到它是一个数组。
You can catch the object inside with {% assign stuff = site.data.navigation.main | where:"text","b" | first %}
您可以使用
{% assign stuff = site.data.navigation.main | where:"text","b" | first %}
来捕获内部对象 {% assign stuff = site.data.navigation.main | where:"text","b" | first %}
{% assign stuff = site.data.navigation.main | where:"text","b" | first %}
. {% assign stuff = site.data.navigation.main | where:"text","b" | first %}
。
