是什么导致了第三行上的错误?
Var product = [{ “名称”:“披萨”, “价格”:“10”, “数量”:“7” },{ “名称”:“Cerveja”, “价格”:“12”, “数量”:“5” },{ “名称”:“汉堡”, “价格”:“10”, “数量”:“2” },{ “名称”:“Fraldas”, “价格”:“6”, “数量”:“2” }); console.log(产品); var b = JSON.parse(products);//意外令牌o

在我的情况下，在我的JSON字符串中有以下字符问题:
r \ \ t \ r \ n \ n ： ＂
我用其他字符或符号替换了它们，然后又从编码中恢复过来。
JSON。parse在参数中等待一个字符串。您需要对JSON对象进行字符串化来解决这个问题。
products = [{"name":"Pizza","price":"10","quantity":"7"}, {"name":"Cerveja","price":"12","quantity":"5"}, {"name":"Hamburguer","price":"10","quantity":"2"}, {"name":"Fraldas","price":"6","quantity":"2"}];
console.log(products);
var b = JSON.parse(JSON.stringify(products)); //solves the problem
Products是一个对象。(从对象字面量创建)
JSON.parse()用于将包含JSON符号的字符串转换为Javascript对象。
您的代码将对象转换为字符串(通过调用. tostring())，以便尝试将其解析为JSON文本。 默认的.toString()返回"[object object]"，这不是有效的JSON;因此出现了错误。
products = [{"name":"Pizza","price":"10","quantity":"7"}, {"name":"Cerveja","price":"12","quantity":"5"}, {"name":"Hamburguer","price":"10","quantity":"2"}, {"name":"Fraldas","price":"6","quantity":"2"}];
改变
products = '[{"name":"Pizza","price":"10","quantity":"7"}, {"name":"Cerveja","price":"12","quantity":"5"}, {"name":"Hamburguer","price":"10","quantity":"2"}, {"name":"Fraldas","price":"6","quantity":"2"}]';
