在对象的JavaScript数组中查找属性

Question

I have a JavaScript array which looks like this. The array contain object of different type.

[
    {
        "className": "XXXX",
        "targets": [
            0,
            1,
            2,
            3,
            4
        ],
        "sClass": "lg" 
    },
    {
        "iDataSort": 0
    },
    {
        "targets": [
            9,
            10
        ]
    },
    {
        "targets": [
            7,
            8,
            9,
            10,
            11,
            12,
            13,
            14,
            15
        ],
        "visible": false,
        "bVisible": false
    }
]

I want to search an element (object) in this array which contains two property with name targets and visible and once I find this object, I want to update the value of targets property.

What is the most efficient way to do this? Is it possible to use underscorejs or lodash for this?

Answer 1

Try to use $.each() along with .hasOwnProperty(propertyName) at this context,

$.each(test, function (i, val) {
    if (val.hasOwnProperty("visible") && val.hasOwnProperty("targets")) {
        alert('yes..')
    }
});
