checkbox

问题 I want to filter a list of JSON objects (Products) by the variable 'category' using a checkbox. a porduct is a followed : { 'bikeId': 6, 'bikeName': 'Kids blue bike', 'bikeCode': 'KB-3075', 'releaseDate': 'June 28, 2016', 'description': 'Kids blue bike with stabalizers', 'category': 'kids', 'price': 290.00, 'starRating': 4.8, 'imageUrl': 'https://openclipart.org/image/2400px/svg_to_png/1772/bike-kid.png' } My current ngFor Loop is as followed: <tr *ngFor="let product of products"> <td><img

问题 In the following example, I use checkbox for making a pure CSS dropdown navigation, also available in this jsFiddle example . Open that fiddle, click "Menu", click "Link 1", and click the "Back" button on the browser toolbar, as you can see the checkbox remains checked, so the navigation is still open. My question is - would it be possible to reset that checkbox to unchecked automatically when going back from the browser history? Any suggestions please? Do I need to use Javascript/jQuery?

问题 For those not familiar, the checked attribute for a checkbox will accept any input as a sign to check the box. in fact, it doesnt need any text. so all these will check the box <input type="checkbox" checked /> <input type="checkbox" checked="false"> <input type="checkbox" checked=""> <input type="checkbox" checked="0"> all those WILL check the box. My problem is i am being handed a checked box, and need to uncheck it. I cant just change its value - that still makes it checked. i need to nuke

问题 I've been using React native for a month now but it's my first time to use a CheckBox in my application. So, lately I've been struggling to check a specific checkbox inside a Flatlist but now I can. But upon testing my checkboxs I did notice that once I check a specific a CheckBox(or more than 1 checkbox) it doesn't UNCHECK. So, my goal is to make a CheckBox that can check(ofcourse) and also uncheck, if ever a user mischeck or mistap a CheckBox. Here's my code export default class tables
