我想解析下面给出的 json 数组。这是我在检查时得到的 json。
0: "Harpic Power Plus Original Liquid Toilet Cleaner" 1: "HARPIC Powerplus Disinfectant Toilet Cleaner, Original - 1L Liquid Toilet Cleaner"
但是当我使用 json.parse() 我得到这个错误
ERROR Error: Uncaught (in promise): SyntaxError: Unexpected token o in JSON at position 1
SyntaxError: Unexpected token o in JSON at position 1

等等，所以最初你已经完成JSON.parse('{ "product_name": [ "Harpic Power Plus Original Liquid Toilet Cleaner", "HARPIC Powerplus Disinfectant Toilet Cleaner, Original - 1L Liquid Toilet Cleaner"]}');并获得了一个数组？那是一个 JS 数组，而不是一个 JSON 数组。您可以使用数组键访问它的值，例如const foo = JSON.parse('{ "product_name": [ "Harpic Power Plus Original Liquid Toilet Cleaner", "HARPIC Powerplus Disinfectant Toilet Cleaner, Original - 1L Liquid Toilet Cleaner"]}'); console.log(foo.product_name[0]); console.log(foo.product_name[1]);希望这有效
