使用javaScript的标准函数中json中的条件？

我有以下功能

compare: function (filterObj, sourceObj, fullMatch) {
            if (!filterObj) {
                return true;
            }
            var filterKeys = Object.keys(filterObj);
            var match = fullMatch;
            for (var i = 0, len = filterKeys.length; i < len; i++) {
                var key = filterKeys[i];
                var value = filterObj[key];
                var isKeyInsourceObj = sourceObj.hasOwnProperty(key);
                var isEqual = value === "*" || value === sourceObj[key];
                var issourceObjPropArr = Array.isArray(sourceObj[key]);
                var isValueArr = value === "*" || Array.isArray(value);

                if (!fullMatch && isKeyInsourceObj) {
                    if (isEqual) {
                        return true;
                    }
                    if (issourceObjPropArr && sourceObj[key].indexOf(value) !== -1) {
                        return true;
                    }
                } else
                    if (fullMatch && isKeyInsourceObj) {
                        var inArr = issourceObjPropArr && (sourceObj[key].indexOf(value) !== -1 || (isValueArr && App.Utils.findOne(sourceObj[key], value)));
                        if (!isEqual && !inArr) {
                            match = false;
                        }
                    }
                    else {
                        match = false;
                    }
            }
            return match;
        },

此功能应定义为通用/标准功能，可在任何地方使用。解决方案：

compare: function (filterObj, sourceObj, fullMatch) {
            if (!filterObj) {
                return true;
            }
            var filterKeys = Object.keys(filterObj);
            var match = fullMatch;
            for (var i = 0, len = filterKeys.length; i < len; i++) {
                var key = filterKeys[i];
                var value = filterObj[key];
                var isKeyInsourceObj = sourceObj.hasOwnProperty(key);
                var isNotUnknown;
                var isEmpty = App.Utils.isEmpty(sourceObj[key]);
                if (!isEmpty) {
                    isNotUnknown = value === "!null";
                }
                var isEqual = value === "*" || value === sourceObj[key] || isNotUnknown;
                var issourceObjPropArr = Array.isArray(sourceObj[key]);
                var isValueArr = value === "*" || Array.isArray(value);

                if (!fullMatch && isKeyInsourceObj) {
                    if (isEqual && isNotUnknown) {
                        return true;
                    }
                    if (issourceObjPropArr && sourceObj[key].indexOf(value) !== -1) {
                        return true;
                    }
                }
                else if (fullMatch && isKeyInsourceObj) {
                        var inArr = issourceObjPropArr && (sourceObj[key].indexOf(value) !== -1 || (isValueArr && App.Utils.findOne(sourceObj[key], value)));
                     if (!isEqual && !inArr && !isNotUnknown) {
                            match = false;
                     }
                }
                else {
                     match = false;
                }
            }
            return match;
        },
    //check value is not undefined or null or 'unknown'
    isEmpty: function (val) {
        return (val === undefined || val == null || val === "unknown") ? true : false;
    },

比较：函数（filterObj、sourceObj、fullMatch）{ 如果（！filterObj）{ 返回true； } var filterKeys=Object.keys（filterObj）； var匹配=完全匹配； 对于（变量i=0，len=filterKeys.length；i

compare: function (filterObj, sourceObj, fullMatch) {
            if (!filterObj) {
                return true;
            }
            var filterKeys = Object.keys(filterObj);
            var match = fullMatch;
            for (var i = 0, len = filterKeys.length; i < len; i++) {
                var key = filterKeys[i];
                var value = filterObj[key];
                var isKeyInsourceObj = sourceObj.hasOwnProperty(key);
                var isNotUnknown;
                var isEmpty = App.Utils.isEmpty(sourceObj[key]);
                if (!isEmpty) {
                    isNotUnknown = value === "!null";
                }
                var isEqual = value === "*" || value === sourceObj[key] || isNotUnknown;
                var issourceObjPropArr = Array.isArray(sourceObj[key]);
                var isValueArr = value === "*" || Array.isArray(value);

                if (!fullMatch && isKeyInsourceObj) {
                    if (isEqual && isNotUnknown) {
                        return true;
                    }
                    if (issourceObjPropArr && sourceObj[key].indexOf(value) !== -1) {
                        return true;
                    }
                }
                else if (fullMatch && isKeyInsourceObj) {
                        var inArr = issourceObjPropArr && (sourceObj[key].indexOf(value) !== -1 || (isValueArr && App.Utils.findOne(sourceObj[key], value)));
                     if (!isEqual && !inArr && !isNotUnknown) {
                            match = false;
                     }
                }
                else {
                     match = false;
                }
            }
            return match;
        },
    //check value is not undefined or null or 'unknown'
    isEmpty: function (val) {
        return (val === undefined || val == null || val === "unknown") ? true : false;
    },
