Whenever a user types '@', it shows up a popover with suggestions and filters when they continue typing. Until here it's easy and I have got it figured out. The problem comes when I need to show the popover if/only if the caret is over the element containing the tag. <div contenteditable=""> <p>Some random text before

问题 What is the best practice to use when swapping an image on a webpage? Altering the image source or just showing/hiding multiple images on the page? 回答1: you have to choose in order to balance speed, with your two options: Altering the image source this way, the page will load faster because it only gets the visible images but it will take a little longer to show the new image when you change src attribute just showing/hiding multiple images this way, you are loading all the images on page

问题 I'm manually compiling a template against a new scope: var scope = _.assign($rootScope.$new(true), { foo: 1, bar: 2 }) var element = angular.element('<my-element foo="foo" bar="bar"></my-element>') $compile(element)(scope) element.appendTo(container) After running a basic profile, the slowest part of this code is $compile , which takes ~1ms per compilation.
