推荐答案

什么都没有内置的...你必须运行一个循环检查重复...

这里有一个样本供你开始...

There is nothing built in for that...You must run a loop to check duplicates...
Here a sample for you to start with...

var json = [
    {"text":"menu1","parent":"#","id":"128102"},
    {"text":"menu1.1","parent":"128102","id":"128103"},
    {"text":"menu1.1","parent":"128102","id":"128103"}
];

var ids = [];
var clean = [];

.each（json，函数（索引，值）{
if （

.each(json, function(index, value) { if(

.inArray（value.id，ids） ）== -1）
{
ids.push（value.id）;
clean.push（value）;
}
}）;

.inArray(value.id, ids) == -1) { ids.push(value.id); clean.push(value); } });

ids数组是检查重复项的辅助工具，只包含原始数组中的唯一ID，其中clean将保存实际数组而不重复...

The ids array is a helper to check for duplicates and contains only the unique ids from the original array, where clean will hold the actual array with no duplicates...
