object

问题 This question already has answers here : LINQ's Distinct() on a particular property (21 answers) Closed 4 years ago . I want to remove the duplicates based on a property of my object: public class MyType { public string _prop1; public string _prop2; public LocationsClass(string prop1, string prop2) { _prop1= prop1; _prop2= prop2; } } ... List<MyType> myList; So basically I want to remove all MyType objects from myList, with the same value in _prop1. Is there a way to do this, probably with

问题 For some reason, the object won't output until the sleep command is done. [pscustomobject]@{message = 'hi'}; sleep 5 Here's another example. You won't see the output until the loop finishes. foreach ($i in 1..60) { if ($i -eq 1) { [pscustomobject]@{message = $i} } sleep 1 } I guess you have to output at least 2 objects to see anything? ¯\_(ツ)_/¯ After 15 seconds, you see both objects. foreach ($i in 1..60) { if ($i -eq 1 -or $i -eq 15) { [pscustomobject]@{message = $i} } sleep 1 } Or output

问题 How would I Find all values by specific key in a deep nested object? For example, if I have an object like this: const myObj = { id: 1, children: [ { id: 2, children: [ { id: 3 } ] }, { id: 4, children: [ { id: 5, children: [ { id: 6, children: [ { id: 7, } ] } ] } ] }, ] } How would I get an array of all values throughout all nests of this obj by the key of id . Note: children is a consistent name, and id 's wont exist outside of a children object. So from the obj, I would like to produce an

问题 I want to use an object as function argument. When I define an object outside fucntion and then pass it as an argument, it works fine: var obj = { a: 0 } function foo(obj){ console.log(this.obj.a); } foo() //0 But when I pass an object directly, it doesen't work: function bar({a: 0}){ console.log(this.arguments.a) } // Uncaught SyntaxError: Unexpected number An object doesent seem to be a legal argument. How do I fix it? 回答1: ES6 supports parameters destructuring. You can use: function bar({a

问题 My debugging work in IE ended today by finding that constructor.name is undefined . I created the following simple code that reproduces the issue: ({}).constructor.name === undefined // => true Is there any workaround to make this work? Maybe overriding somehow the prototype? If possible, I don't want to change the syntax, because the change would be major. JSFIDDLE 回答1: The problem is simply that the name property of function objects is not supported in Internet Explorer. The property is non

问题 I'm making a game in pygame and I have made an 'abstract' class that's sole job is to store the sprites for a given level (with the intent of having these level objects in a list to facilitate the player being moved from one level to another) Alright, so to the question. If I can do the equivalent of this in Python(code curtesy of Java): Object object = new Object (){ public void overriddenFunction(){ //new functionality }; }; Than when I build the levels in the game I would simply have to
