js 去掉数组中重复的对象

function deteleObject(obj) {

// console.log(obj)

var uniques = [];

var stringify = {};

for (var i = ; 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 = ; 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;

}

}

app.uniques = uniques

return uniques

return uniques.length;

}
