operators

问题 I need to use the OR operator in a jQuery if statement to filter out 10 states. My code works wile only excluding one state, but fails when i try to include multiple states. Is there a correct way to do this? Code I am am using : if ((state != 10) || (state != 15) || (state != 19) || (state != 22) || (state != 33) || (state != 39) || (state != 47) || (state != 48) || (state != 49) || (state != 51)) return true; Thanks 回答1: Think about what if ((state != 10) || (state != 15) || (state != 19) |

问题 I'm using $match of aggregation. and I tried this. $match : { $not: { 'A': false, 'B': 'condition' } } but not work like nand. it works like not A and not B. How can I query with Not(A and B) ? 回答1: The $not operator does not invert a complex expression. You need to use $and or $or for complex expressions. Using logic rules, we know that the following are identical: not ( A and B ) = not A or not B Using the MongoDB query language, you would have: db.collection.find({$or:[{"a":{"$ne":false}},
