我有一个 div，它以 json 格式输出文本:
HTML
<div id="myMap"></div>
JS
$('#myMap').text(JSON.stringify(out[0], null, 2));
这给了我:
{ "name": "Leopardi", "children": [ { "name": "Vita", "children": [ { "name": "Ubriacone" } ] }, { "name": "Poesie", "children": [ { "name": "L'infinito" } ] } ] }

我试图让输出像这样:

最佳答案
如果您尝试从 JSON 字符串创建对象，请查找 JSON.parse():
var out = [{
"name": "Leopardi",
"children": [{
"name": "Vita",
"children": [{
"name": "Ubriacone"
}]
}, {
"name": "Poesie",
"children": [{
"name": "L'infinito"
}]
}]
}];
$('#myMap').text(JSON.stringify(out[0], null, 2));
var root = JSON.parse( $('#myMap').text() ); // <-- JSON.parse
console.log('root.name:', root.name); // <-- can treat 'root' as object#myMap {
border: 1px solid;
padding: .5em;
font-family: monospace;
white-space: pre;
