methods1. How to determine the state of an animationThere is no independent method, but it is judged by the IS method.$ (' #mover '). Is (": animated")2. Delay AnimationThe method for implementing the animation delay is the delay method, and the time when the parameter is passed in.Typical usage:$ (this). Animate ({left: "400px", Height: "200px", Opacity: "1"}, (+).). Animate ({top: "200px", Width: "200px" }, (FadeOut). Delay ("slow");3. Stop the animationThe Stop method is used to stop the ani

complexity.First, the ability to anticipate high performance is a selector that can be used directly from the JavaScript native method. For example, $ ("#id"), $ ("div") have local methods corresponding to it: document.getElementById (),document.getelementbytagname (). While $ (". Class"), $ ("[Attribute=value]"), $ (": hidden"), such selectors do not have local method implementations, mostly using DOM search method to achieve the effect, so from the performance considerations, the latter metho

Improvement of front-end programming (13th) ---- jquery Selector Jquery represents javascript and query, which is the class library for javascript query operations. jquery is a fact standard in the web Front-end field. I recently read "sharp jquery" and found that the biggest feature of this book is that a deeper discussion of jquery's usage situations and optim

corresponds to the data when the data changes, and then modify the DOM. If the HTML changes, such as the ID of an element is changed, and jquery uses the ID to find that element, the jquery code needs to be modified. And, if the page's data is complex to interact with the DOM, it's cumbersome to use JQuery. In these cases, the framework of MVVM is a good choice: the way that MVVM interacts with the page is to set the DOM's relationship with the data in HTML. The framework updates the DOM when t

is bound to the current object. The function invocation pattern. When a function is not a property of an object, it is invoked as a function. This binds to the global object. constructor invocation mode. If the call is preceded by the new operator in front of a function, a new instance object that hides the prototype prototype object linked to the function is created, and this is bound to the new instance object. (constructor function usually starts with uppercase letters) The

If we say that iQiYi was a temporary assault DIV + CSS at the beginning, we have now experienced that all technologies must be aware of the principles so that we can be an expert. Css attributes and usage are all there, but if they are us

Netease front-end micro-major, JavaScript programming basics: basic syntax, basic type Ignore the basic syntax section. The basic types are as follows: 1. JS contains six data types: Number, String, Boolean, Object, Null, and Undefined. They are classified into the original type and reference type by type. Object is the reference type, and the other five types are the original types. 2. Let's talk about Nu

I started to read "Java programming thoughts" in July. Today I have no motivation to read it, so I decided to come to an end. Why is there no motivation? The time for reading this book is in the spare time. Sometimes I don't want to read it when I come back from work, so sometimes I read it intermittently and find that reading it is not efficient. Then, I feel that I really need some java experience to bet
