推荐答案
通过键迭代:
(对Amit Gupta答案的增强)
Iterate through the keys: (enhancement to Amit Gupta's answer)
var result = [];
getNames(data, "name");
document.write("result: " + result.join(", "));
function getNames(obj, name) {
for (var key in obj) {
if (obj.hasOwnProperty(key)) {
if ("object" == typeof(obj[key])) {
getNames(obj[key], name);
} else if (key == name) {
result.push(obj[key]);
}
}
}
}

"size": 36,
"style": "bold",
"name": "text1",
"hOffset": 250,
"vOffset": 100,
"alignment": "center",
"onMouseUp": "sun1.opacity = (sun1.opacity / 100) * 90;"
}
}
}
let result = [];
getNames(data, "title");
document.write("result: " + result.join(", "));
function getNames(obj, name) {
for (var key in obj) {
if (obj.hasOwnProperty(key)) {
if ("object" == typeof(obj[key])) {
