object

问题 I'm new to python and I was reading about Dictionaries. And from my previous experience with langages like javascript they seemed like objects to me. Dictionaries can store lists and share many similaraties to objects in javascript. ex python code: menu = {} menu['Chicken Alfredo'] = 14.50 menu['Italian Pasta'] = 15.89 menu['Shrimp Soup'] = 12.43 menu['Persian Rice'] = 21.99 ex javascript code: var menu = new Object(); menu['Chicken Alfredo'] = 14.50; menu['Italian Pasta'] = 15.89; menu[

问题 For exemple, i have 3 inputs <input type="text" name="color" value="blue"/> <input type="text" name="flavor" value="acid"/> <input type="text" name="name" value="jack"/> And a i need get something like this const obj = {color:'blue', flavor:'acid', name:'jack}; I tried use a for loop, but i get a array, not a object var obj = []; var x = document.querySelectorAll('input'); for (var i = 0; i < x.length; i++) { obj.push(x[i].value) } console.log(obj); 回答1: You can loop through the values using

问题 I am in a programming class that has provided me with a project but I have no idea where to start and was hoping someone could push me in the right direction. I am only posting part of the project so that someone can show me a bit of the code to get an idea of how its done as I have taken a programming class before but I am out of practice. Create an application called Registrar that has the following classes: A Student class that minimally stores the following data fields for a student: Name

问题 I have created an array of objects that needs to be stored and kept for another page. The array of objects is similar to this: var cheese_array = [ { name: "Chedder", age: "34", smelly: true }, { name: "Brie", age: "4", smelly: false }, { name: "Blue Stilton", age: "13", smelly: true } ]; But when I JSON.stringify() it, it doesn't stringify the objects, only the array. So I end up with and array that looks like this: [object Object], [object Object], [object Object] So how do you stringify

问题 what is the best way to convert an object of arrays to an array of objects and vice-versa { category : ['a','b','c'], title : ['e','f','g'], code : ['z','x','v'] } To [ { category : 'a', title : 'e', code : 'z' }, { category : 'b', title : 'f', code : 'x' }, { category : 'c', title : 'g', code : 'v' }, ] 回答1: You could use two function for generating an array or an object. They works with Object.keys for getting all own property names, Array#reduce for iterating an array and collecting items

问题 I have an array of key/value pairs. The keys are sometimes duplicated, and the values are always unique per key. I want to condense each unique key to an object, so that I have a key and an array of the associated values as a property. Are there any handy javascript functions to do this? This pairArray = [ { key: "a", value: "1" }, { key: "a", value: "2" }, { key: "b", value: "1" }, { key: "b", value: "2" }, ]; Becomes objectArray = [ { key: "a", values: ["1", "2"] }, { key: "(", values: ["1"

问题 Background: I have parsed key-value pairs that I imported into objects. I did this because I want to be able to sort by the name properties which the logic is easy for: var varDupe = variableList.GroupBy(v => v.varName).Where(vName => vName.Count() > 1).Select(vName => vName.Key); I debated between these and a dictionary list, but in the end it seemed like searching was easier as I don't need to export these key-value pairs, only error-check them. I will need a lot of dependencies like

问题 I am using antd checkbox . I am storing checked value by using array of value , but I need to store unchecked array of value . const plainOptions = ["Apple", "Pear", "Orange"]; const defaultCheckedList = ["Apple", "Orange"]; state = { checkedList: defaultCheckedList }; onChange = checkedList => { this.setState({ checkedList }); }; onCheckAllChange = e => { this.setState({ checkedList: e.target.checked ? plainOptions : [] }); }; onCheckItem = value => e => { this.setState({ checkedList: this
