var details = [
            {
                reference: 'ref-1',
                description: 'desc-1',
                price: 1
            }, {
                reference: '',
                description: '',
                price: ''
            }, {
                reference: 'ref-2',
                description: 'desc-2',
                price: 200
            }, {
                reference: 'ref-3',
                description: 'desc-3',
                price: 3
            }, {
                reference: '',
                description: '',
                price: ''
            }
        ];

        scope.removeEmptyDetails(details);
        expect(details.length).toEqual(3);

scope.removeEmptyDetails = function(details){
            _.remove(details, function(detail){
                return (_.isEmpty(detail.reference) && _.isEmpty(detail.description) && _.isEmpty(detail.price));
            });
        };

几个简单的方法：

var arr = [1,2,,3,,-3,null,,0,,undefined,4,,4,,5,,6,,,,];

arr.filter(n => n)
// [1, 2, 3, -3, 4, 4, 5, 6]

arr.filter(Number) 
// [1, 2, 3, -3, 4, 4, 5, 6]

arr.filter(Boolean) 
// [1, 2, 3, -3, 4, 4, 5, 6]

或-（仅适用于“text”类型的单个数组项）

['','1','2',3,,'4',,undefined,,,'5'].join('').split(''); 
// output:  ["1","2","3","4","5"]

或-经典方式：简单迭代

var arr = [1,2,null, undefined,3,,3,,,0,,,[],,{},,5,,6,,,,],
    len = arr.length, i;

for(i = 0; i < len; i++ )
    arr[i] && arr.push(arr[i]);  // copy non-empty values to the end of the array

arr.splice(0 , len);  // cut the array and leave only the non-empty values
// [1,2,3,3,[],Object{},5,6]

jQuery：

var arr = [1,2,,3,,3,,,0,,,4,,4,,5,,6,,,,];
    
arr = $.grep(arr, n => n == 0 || n);
// [1, 2, 3, 3, 0, 4, 4, 5, 6]

以上答案都不适用于所有类型。下面的解决方案将删除null、undefined、｛｝[]、NaN，并保留日期字符串，最好的是它甚至从嵌套对象中删除。

function removeNil(obj) {
    // recursively remove null and undefined from nested object too.
    return JSON.parse(JSON.stringify(obj), (k,v) => {
      if(v === null || v === '') return undefined;
      // convert date string to date.
      if (typeof v === "string" && /^\d\d\d\d-\d\d-\d\dT\d\d:\d\d:\d\d.\d\d\dZ$/.test(v))
        return new Date(v);
      // remove empty array and object.
      if(typeof v === 'object' && !Object.keys(v).length) return undefined;
      return v;
    });
  }

函数removeNil（obj）{//递归地从嵌套对象中删除null和undefined。返回JSON.parse（JSON.stringify（obj），（k，v）=>{如果（v===null||v===''）返回undefined；//将日期字符串转换为日期。if（typeof v==“string”&&/^\d\d\d\d-\d\dT\dd:\d\d:\d\d.d.d\dZ$/.test（v））返回新日期（v）；//删除空数组和对象。if（typeof v=='object'&&！object.keys（v）.length）返回undefined；返回v；});}常量ob={s： “a”，b： 43中，国家：['a'，'b'，'c']，l： 空，n： ｛ks:“a”，efe:null，ce:“”｝，d： new Date（），nan:nan，k： 未定义，emptyO:{}，emptyArr:[]，}常量输出=removeNil（ob）；console.log（输出）；console.log（'测试：'，ob.countries.length，typeof（ob.d））

如果有人想要清理整个阵列或对象，这可能会有所帮助。

var qwerty = {
    test1: null,
    test2: 'somestring',
    test3: 3,
    test4: {},
    test5: {
        foo: "bar"
    },
    test6: "",
    test7: undefined,
    test8: " ",
    test9: true,
    test10: [],
    test11: ["77","88"],
    test12: {
        foo: "foo",
        bar: {
            foo: "q",
            bar: {
                foo:4,
                bar:{}
            }
        },
        bob: {}
    }
}

var asdfg = [,,"", " ", "yyyy", 78, null, undefined,true, {}, {x:6}, [], [2,3,5]];

function clean_data(obj) {
    for (var key in obj) {
        // Delete null, undefined, "", " "
        if (obj[key] === null || obj[key] === undefined || obj[key] === "" || obj[key] === " ") {
            delete obj[key];
        }
        // Delete empty object
        // Note : typeof Array is also object
        if (typeof obj[key] === 'object' && Object.keys(obj[key]).length <= 0) {
            delete obj[key];
        }
        // If non empty object call function again
        if(typeof obj[key] === 'object'){
            clean_data(obj[key]);
        }
    }
    return obj;
}

var objData = clean_data(qwerty);
console.log(objData);
var arrayData = clean_data(asdfg);
console.log(arrayData);

输出：

删除任何null、undefined、“”、“”空对象或空数组

jsfiddle在这里

这是可行的，我在AppJet中测试了它（你可以复制粘贴代码到它的IDE上，然后按“reload”查看它的工作情况，不需要创建帐户）

/* appjet:version 0.1 */
function Joes_remove(someArray) {
    var newArray = [];
    var element;
    for( element in someArray){
        if(someArray[element]!=undefined ) {
            newArray.push(someArray[element]);
        }
    }
    return newArray;
}

var myArray2 = [1,2,,3,,3,,,0,,,4,,4,,5,,6,,,,];

print("Original array:", myArray2);
print("Clenased array:", Joes_remove(myArray2) );
/*
Returns: [1,2,3,3,0,4,4,5,6]
*/

要从数组中删除未定义的元素，只需使用

常量数组=[｛name:“tim”，年龄：1｝，未定义，{姓名：“ewrfer”，年龄：22岁}，{姓名：“3tf5gh”，年龄：56}，无效的{姓名：“kygm”，年龄：19岁}，未定义，];console.log（array.filter（布尔））；
