JavaScript中常见的数据格式化方式详解

response = '{"title": "住址", "dataIndex": 'address',key: 'address'}'

console.log(JSON.stringify(JSON.parse(reponse)) ; //先将接口相应数据转为对象，再序列化。
  // 打印结果如下
{
    "title": "住址",
    "dataIndex": "address",
    "key": "address"
}

console.log(JSON.stringify({"title": "住址",dataIndex: 'address',key: 'address'}, null, "---"))
{
---"title": "住址",
---"dataIndex": "address",
---"key": "address"
}

console.log(JSON.stringify({"title": "住址",dataIndex: 'address',key: 'address'}, null, "\t"))
{
	"title": "住址",
	"dataIndex": "address",
	"key": "address"
}

console.log(JSON.stringify({"title": "住址",dataIndex: 'address',key: 'address'}, null, " "))
{
 "title": "住址",
 "dataIndex": "address",
 "key": "address"
}

//有些人按照习惯的方式将树状结构的子结构写成children
{
    a: 1,
    children: [
        {b: 1}
    ]
}
//但是有些人就随心所欲惯了，非写成childList
{
    a: 1,
    childList: [
        {b: 1}
    ]
}

JSON.stringify({
    a: 1,
    childList: [
        {b: 1}
    ]
}).replace("childList", "children")

  var a = "此例演示如何使用 pre 标签 \n对空行和 空格\n进行控制";
  <pre>{a}</pre>

<p>这是一段文本段落</p>
<br/>
<div>这是另一段</div>

var a = "<p>这是一段文本段落</p>
<br/>
<div>这是另一段</div>"

<div dangerouslySetInnerHTML={{__html: a}}></div>
