Today share an element of the periodic motion table, this is not a chemical element, you can be understood as "elemental motion law", because this element table is composed of some common dynamic effects, and each dynamic implementation has a theoretical basis, and not imagined out of thin air. The effects are bending, offset, flow line, noise, cyclotron path, polar coordinates, audio wave, symmetrical rota
Waiting for a long time can be a large frame, such as a series of effects motion frame, is now a preliminary version, to meet the needs. Let's see how it's achieved.We know in JavaScript that '. ' Equivalent to ' [] ' For example: odiv.style.height=odiv.style[' height ']So, let's move the property as a parameter and pass it to the previous function.Transparency, need to be dealt with alone, can be judged.directly on the code.styletype= "Text/css">Div{
Implementation of Javascript multi-object motion and javascript Object Motion

1. In the Apple 5s we clicked on the camera image and went to the "camera mode" of the cell phone.
2. As shown in the following illustration, we slide the slow action bar on the screen of the photo interface and click on the "recording" details as shown in the picture.
3. Now we can click on the White button to take a picture while filming. If not, click the red button directly, as shown in the following figure.
4. After the shoot, we can preview in the phone to see the slow
1. Open the desktop gesture software, the taskbar has a shortcut icon appears.
2. The first time to open a video tutorial, practice gesture recognition operation.
3. The following is a description of the operation of each gesture.
4. Of course, when running gestures, you can also close the video window, as long as the gesture software running in the background. The
The first step:First, get the div you want to change.var Obox=document.getelementbyid (' box '); div ObjectStep Two:(1). Define a move function. How to define?What do we have to do first? How does it work? The finishing touches after the operation?-----> OBox (div object)-----> What do we want him to look like? For example, left changes, such as top changes. This must be in the form of JSON. {left:200, top:400}-----> Finishing work? That's a function. Optional.Move (obj, JSON, options)Step Three

D: distance between two circles. A: R1-> O1-> O2
Cos A = (R1-R2)/X if O1 is (0, 0) and O2 is (x, 0), the above two cut points are (R1 * cosa, R1 * Sina ), (x + R2 * cosa, R2 * Sina) the general position is translated and rotated based on the result.
Known circle O1, O2, coordinate (x1, Y1), (X2, Y2), radius is R1, R2

Chain movement, as the name implies, tied up, that is, after the execution of an event, then proceed to the next event, the argument above the foot, the next function to execute the name as a parameter, that is, the use of the return function, the following code appears in the FN, that is, the return function,1 functionMove (OBJ,ATTR,TARGET,FN) {2 clearinterval (obj.timer);3Obj.timer = SetInterval (function(){4 varIcur=0;5 if(attr = = ' opacity ') {6Icur=parseint (parsefloat (GetStyle (o
What I'm talking about here is the kind of uniform motion, mainly by changing the left and top values of a box die to achieve motion, or, changing the properties of the shape itself, to move:function GetStyle (obj,name) {return Obj.currentstyle?obj.currentstyle[name]:getcomputedstyle (obj,false) [name];}; function Move (obj,json,options) {options=options| | {};options.time=options.time| | 700;var Start={};v
(39) JS motion buffering and 39js motion Buffering
Basic Idea: the timer is used to make the object move to the right. In the process of motion, it is not a constant speed, but fast and slow, that is, the larger the distance, the faster the speed, the smaller the distance, the lower the speed, but when the end point is reached, you must use the rounded up Math fu
A. Circular motion
1.1 Thought Analysis:
The equations of the circle are:
(x0, y0) is the center of the circle; (x, y) is the point on the circle.(x-x0) ^ 2 + (y-y0) ^ 2 = r ^ 2cos (angle) ^ 2 + sin (angle) ^ 2 = 1Therefore, the combination of the above two-type, can be:
x = R * cos (angle) + x0y = R * sin (angle) + y0
Therefore, the sine function is used to compute the y-coordinate and the cosine function is used to compute the x-coordinate.

For example, the following types of data can be found: washing, reading, exploring, and reading.
Motion 2 (Class 2 verb)-including the previous verb and the next verbA verb must end with a verb.The previous verb "begin" is a forward segment, for example, "begin" and "begin ".The next section of the verb "before" is "waiting for", for example, "waiting for" and "

Accelerated motion, that is, an object moving faster and faster, deceleration movement, that is, an object moving faster and slower. Now using JavaScript to simulate these two effects, the principle is to use setinterval or settimeout to dynamically change the distance between an element and another element, such as Xxx.style.left or xxx.style.marginLeft, and then each movement after the increase in speed, so that the effect of accelerated movement ap
Why is the speed of 24 frames per second sufficient for a movie to achieve a smooth visual effect, but it seems bumpy for computer games? The reason is very simple. when the camera is working, it does not take a frame at rest. Each frame it takes already contains all the visual information within 1/24 seconds, including the object displacement. If you press the seek key when watching the video, what we get is not a clear static image, but a blurred image, because of this. The computer cannot do
