//数组对象去重复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;},
