js 去掉陣列物件中的重複物件

在陣列物件中去掉重複的物件:

 

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; }
