Question

在jsonlint上，以下JSON显示错误：预期为'EOF'，得到了'，'。问题在第10行显示为逗号。

 {
            "name": "Professional",
            "children": [{
                "name": "Professional Behavours"
            }, {
                "name": "Self-Care and Self-Awareness"
            }, {
                "name": "Medical Ethics and Law"
            }]
        }, {
            "name": "Leader",
            "children": [{
                    "name": "Teamwork and Leadership"
                }, {
                    "name": "Collaborative Practice"
                }, {
                    "name": "Health Systems and Careers"
                }]
            }
        }

添加外部方括号后，JSON显示为有效。

但是，我将JSON与d3.js一起使用，不允许使用外部方括号。 d3.js也无法识别下面的JSON。

应如何在没有外部方括号的情况下正确格式化此JSON？

感谢答案，这项工作有效：

{
    "name": "Condition",
    "children": [{
        "name": "Professional",
        "children": [{
                "name": "Professional Behavours"
            },{
                "name": "Self-Care and Self-Awareness"
            },{
                "name": "Medical Ethics and Law"
            }]
    }, {
        "name": "Leader",
        "children": [{
                "name": "Teamwork and Leadership"
            },{
                "name": "Collaborative Practice"
            },{
                "name": "Health Systems and Careers"
            }]
    }]
}

Answer 1

因为您的JSON具有多个根元素（除了末尾的额外}外）。看起来就是这样

{
  ...
}, // <-- It expects EOF but gets ','
{
  ...
}

有效的JSON应该具有一个根元素，即

{
  ...
}

因此，当您添加[]时，它将成为一个数组，并且现在具有单个有效的根元素，即

[
  {
    ...
  },
  {
    ...
  }
]

Answer 2

您有多个根对象，因此不是有效的JSON。根可以是对象{}或数组[]。

在您的情况下，我要使用Array：

[
    {
        "name": "Professional",
        "children": [
            {
                "name": "Professional Behavours"
            },
            {
                "name": "Self-Care and Self-Awareness"
            },
            {
                "name": "Medical Ethics and Law"
            }
        ]
    },
    {
        "name": "Leader",
        "children": [
            {
                "name": "Teamwork and Leadership"
            },
            {
                "name": "Collaborative Practice"
            },
            {
                "name": "Health Systems and Careers"
            }
        ]
    }
]

或者如果您希望将根作为对象：

{
    "a" : {
        "name": "Professional",
        "children": [
            {
                "name": "Professional Behavours"
            },
            {
                "name": "Self-Care and Self-Awareness"
            },
            {
                "name": "Medical Ethics and Law"
            }
        ]
    },
    "b": {
        "name": "Leader",
        "children": [
            {
                "name": "Teamwork and Leadership"
            },
            {
                "name": "Collaborative Practice"
            },
            {
                "name": "Health Systems and Careers"
            }
        ]
    }
}

JSON-预期为“ EOF”，得到“，”
