假設(shè)有個數(shù)組對象是這樣var qq = [
{ "group": 100, "info": {"event": 123}, "name": "paul",
},
{ "group": 100, "info": {"event": 323}, "name": "james", "sp": 1
},
{ "group": 103, "info": {"event": 123}, "name": "jess", "sp": 13,
},
{ "group": 103, "info": {"event": 323}, "name": "andy", "sp": 10
},
{ "group": 103, "info": {"event": 123}, "name": "will", "sp": 1
},
{ "group": 109, "info": {"event": 123}, "name": "jason", "sp": 1
}
];group一樣表示是一組的那我要如何跑出每個的索引位置，像這樣 0,1,0,1,2,0
如何得知元素在數(shù)組中的某個位置
