篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了操作JSON数据相关的知识，希望对你有一定的参考价值。
操作标准JSON数据，递归实现如下：
String.prototype.startWith = function(compareStr) {
return this.indexOf(compareStr) == 0;
}
// 生成以rootNode为根节点的树
function generateSubtree(rootNode, childrenJson) {
for(var idx = 0; idx < childrenJson.length; ++idx) {
var child = childrenJson[idx];
// 子节点
var childNode = {
"name": child.name,
"desc": child.desc,
"dsp=": child.name.startWith("节点-1") ? "Y" : "N",
"children": []
};
// 如果有孩子则生成其子树
if (child.children != null && child.children != \'[]\') {
generateSubtree(childNode, child.children);
}
// childNode子树作为rootNode的孩子
rootNode.children.push(childNode);
}
}
