哦，天哪，之前所有答案中的解决方案对我都不起作用。我刚才也遇到了类似的问题。我设法解决了它与包装与报价。请看截图。喔!

原:

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

Products是一个数组，可以直接使用:

var i, j;

for(i=0; i<products.length; i++)
  for(j in products[i])
    console.log("property name: " + j, "value: " + products[i][j]);

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"}]';

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

我的问题是，我通过Ajax在PHP回调函数中注释了HTML，该函数正在解析注释并返回无效的JSON。

一旦我删除了带注释的HTML，一切都很好，JSON被解析没有任何问题。
