js 数组中如何删除字典

区别：

[]表示是一个数组，如var strs = ['a','b','c']。{}表示是一个对象，比如，
var obj = {
name: '宙斯',
sex: 1
}

如何在数组中删除指定对象呢？？

[
    {
        "id": 12,
        "title": "fdsfsdds",
        "markdown": "fsdafafs",
        "counttet": "fsdafafs"
    },
    {
        "id": 13,
        "title": "fdsfsdds",
        "markdown": "fsdafafs",
        "counttet": "fsdafafs"
    },
    {
        "id": 14,
        "title": "fdsfsdds",
        "markdown": "fsdafafs",
        "counttet": "fsdafafs"
    },
    {
        "id": 16,
        "title": "fdsfsdds",
        "markdown": "fsdafafs",
        "counttet": "fsdafafs"
    },
   ]

方法： index可以是动态的，这样就能指定删除某一对象

splice(index,1)
