js数组对象去重

转: 

在数组对象中去掉重复的对象:

export function deteleobject(obj) {
    var uniques = [];
    var stringify = {};
    for (var i = 0; i < obj.length; i++) {
        var keys = object.keys(obj[i]);
        keys.sort(function(a, b) {
            return (number(a) - number(b));
        });
        var str = '';
        for (var j = 0; j < keys.length; j++) {
            str += json.stringify(keys[j]);
            str += json.stringify(obj[i][keys[j]]);
        }
        if (!stringify.hasownproperty(str)) {
            uniques.push(obj[i]);
            stringify[str] = true;
        }
    }
    uniques = uniques;
    return uniques;
}
