js獲取數組，進行循環處理，添加，刪除，查找等操作

//js循環 添加
that.workTypeActiveIds.forEach(function (value, key, iterable) {
                                    console.log(key, value, iterable);

                                    var work = that.workTypesItemAll.find(function (work) {
                                        return work.id === value
                                    });
                                    that.WorkTypeActiveTtems.push(work);
                                    that.workTypes.push(work.text);
                                });

js查找索引和刪除

 // 查詢元素在數組中的索引值
        Array.prototype.indexValue = function (arr) {
            for (var i = 0; i < this.length; i++) {
                if (this[i] == arr) {
                    return i;
                }
            }
        }
        Array.prototype.remove = function (val) {
            var index = this.indexOf(val);
            if (index > -1) {
                this.splice(index, 1);
            }
        };

根據值進行查找

  var salary = that.salaryList.find(function (salary) {
                                return salary.id === result.JobInfo.SalaryTypeId;
                            });
