object

问题 I have an object returned from a server that contains e.g. { lorem: 1, ipsa: [2,3], dolor: { sit: 'amet', consectetur: 'adipiscing'}, elit: [{you: 'get'}, {the: 'picture'}] } and a TypeScript interface of export interface smallerInterface { ipsa: number[]; elit: any[]; } I'm saving the returned object into IndexedDb, and don't want to save any fields that are not present on the interface. I have tried casting fullObject as smallerInterface and <smallerInterface>fullObject , but when saving

问题 I got this path array: const path = ["a", "b", "c", "d"] and an object like: let obj = { "a": { "b": { "c": { "d": 10, "e": 20 } } } } and I would like to delete that obj["a"]["b"]["c"]["d"] so my obj will be { "a": { "b": { "c": { "e": 20 } } } } I've tried to do some path.forEach looping, appending it but couldn't find a proper way which I appended it as I wish to, so I could access obj to the right place. 回答1: You could do this recursively and then use delete to remove the final key-value

问题 I have an array of Objects that have 6 properties. That look like this: $csvData CURRENT DATE AND TIME : 07/10/2015 08:17:17 CST USER NAME : userName COMPUTER NAME : computerName IP ADDRESS : 192.168.1.1 LOGON SERVER : logonServer LOGON/OFF : logon I want to create an array of objects where username and computer name are not duplicated. How can I get only the unique username/computername combo in powershell? Ultimately I would like to remove all duplicates and add a property 'Count' that

问题 Is there a way to create an event that will fire when an object's attributes/field values change? For instance, if the object has a field called private int number; And the user performs an action that would update that number, an event would fire that would update all of the text boxes on the form to display current field values? EDIT: Sorry, yes properties have been created for each field. 回答1: Make it a property rather than a field, and implement INotifyPropertyChanged in your class :
