将类似数组的字符串解析为JavaScript中的json对象数组

Question

I have a String in the following format:

[{"type":"relativeHumidity","unit":"%","resolution":300,"accuracy":0.0,"period":"INSTANT","correction":false,"completenessRatios":[{"completenessRatio":0.0,"period":"SIX_MONTHS"},{"completenessRatio":0.0,"period":"THIRTY_DAYS"},{"completenessRatio":0.5789037386601943,"period":"FULL_HISTORY"}]},{"type":"temperature","unit":"C","resolution":300,"accuracy":0.0,"period":"INSTANT","correction":false,"completenessRatios":[{"completenessRatio":0.0,"period":"SIX_MONTHS"},{"completenessRatio":0.0,"period":"THIRTY_DAYS"},{"completenessRatio":0.5789037386601943,"period":"FULL_HISTORY"}]}]

It resembles an array of two json objects. I need to retrieve these JSON objects.

I have tried to parse it using JSON.parse(str) but complaints about the "," that separates JSONs in this array-like structure.

I have tried doing str.split(",") but it splits by each comma, eg

  [0] [{"type":"relativeHumidity"

  [1] "unit":"%"

I have tried removing first and last brackets and reading it as an array:

var arr = [str.substr(1, value.length - 2)];

[ '{"type":"relativeHumidity","unit":"%","resolution":300,"accuracy":0.0,"period":"INSTANT","correction":false,"completenessRatios":[{"completenessRatio":0.0,"period":"SIX_MONTHS"},{"completenessRatio":0.0,"period":"THIRTY_DAYS"},{"completenessRatio":0.5789037386601943,"period":"FULL_HISTORY"}]},{"type":"temperature","unit":"C","resolution":300,"accuracy":0.0,"period":"INSTANT","correction":false,"completenessRatios":[{"completenessRatio":0.0,"period":"SIX_MONTHS"},{"completenessRatio":0.0,"period":"THIRTY_DAYS"},{"completenessRatio":0.5789037386601943,"period":"FULL_HISTORY"}]}' ]

but it creates an array of a single string.

Any help on how to read that string into an array of JSON objects will be greatly appreciated.

Answer 1

this works for me (no JSON parse error) > JSON.parse('[{"type":"relativeHumidity","unit":"%","resolution":300,"accuracy":0.0,"period":"INSTANT","correction":false,"completenessRatios":[{"completenessRatio":0.0,"period":"SIX_MONTHS"},{"completenessRatio":0.0,"period":"THIRTY_DAYS"},{"completenessRatio":0.5789037386601943,"period":"FULL_HISTORY"}]},{"type":"temperature","unit":"C","resolution":300,"accuracy":0.0,"period":"INSTANT","correction":false,"completenessRatios":[{"completenessRatio":0.0,"period":"SIX_MONTHS"},{"completenessRatio":0.0,"period":"THIRTY_DAYS"},{"completenessRatio":0.5789037386601943,"period":"FULL_HISTORY"}]}]');

tried it in chrome console

尝试这个：

var jsonArray = JSON.stringify({ "type":"relativeHumidity","unit":"%","resolution":300,"accuracy":0.0;})
