key-value

问题 I wrote this piece of code, that should parse the given paramUnparsed (which should be an array in the form: [key1=val1, key2=val2, .., keyn=valn] ). function parseParams(paramUnparsed){ var params = []; for ( var j = 0; j < paramUnparsed.length; j++) { if (paramUnparsed[j].split('=').length < 2) { // error ! bad input structure, ignoring params - params = undefined; break; // we don't have to return error, depending // on the function called and given params. } //else { var key =

问题 I'm working on a personal project to learn about Redis. I'm trying to use it as the database for managing a hotel. I'm trying to wrap my head around how to manage reservations. The problem is, there are multiple rooms, and each room can have multiple reservations, storing date-from and date-to. I'm just unsure how i could model this, to efficiently be able to find an empty room for a given given period. Currently, I've been thinking of storing reservations, for each seperate room, in sorted

问题 I have a JSON structure like this: { "1": "a-secret", "A": "b-secret", "2": { "3": "ab-secret", "4": { "5": "adc-secret" }, "6": { "7": "abdc-secret" } } } I am trying to create a command (preferable one liner) to return key pairs that only have string values. So for the above it would return: { "1": "a-secret", "A": "b-secret" } I have found .[]|strings that returns only the string values but I need both the key and value and that's where I'm stumped! 回答1: You are looking for map_values. $

问题 NSDictionary has objectForKey but it's case-sentive for keys. There is No function available like - (id)objectForKey:(id)aKey options:(id) options; where in options you can pass "NSCaseInsensitiveSearch" To get key's from NSDictionary which is case-insesitive one can use the following code written below. 回答1: This isn't included for a couple of reasons: NSDictionary uses hash equality, and for pretty much any good hashing algorithm, any variation in the source string results in a different
