I. BASIC OBJECTIVESWrite a layer that follows the mouse movement,The position of the current mouse appears in the layer,Such asThis layer uses jquery instead of JavaScript because the jquery code makes it easy to be compatible with all current mainstream browsers, at least IE8 without any problems, without the need for compatibility with large sections of JavaScript code.Second, the production processAt the heart of this experiment is the MouseMove event in jquery,The mouse movement is triggered
First I define 3 div each div when I put the mouse on the time, his width is expressed, such asThe first is the style and HTML code1 style>2 Div{3 width:100px;4 Height:50px;5 background:Red;6 Margin-bottom:10px;7 }8 style>9 Ten Body> One Div>Div> A Div>Div> - Div>Div> - Body>JS code is as follows, with comments1 + It's not hard, the key into the function is to clean up the timer.JS for basic motion

Cocos2dx animation is amazing ~~, What we see here is an object that is constantly flipped during motion. Two animations come together ~~
The following code involves: ccanimation (Compensation animation) ccanimate (animation) ccdelaytime (delayed action) ccfadeto (set transparent attitude) ccsequence (action sequence) ccspawn (allows several animations of the genie to be executed simultaneously) ccrepeateforever (infinite loop) cccallfuncn (node call

How js achieves buffering motion effect
The specific analysis is as follows:
The instance can be quickly started and then slowed down until it is stopped.
Key points:
1
Var speed = (target-box.offsetLeft)/8;
The value of the target point minus the current position of the element is divided by 8, because the value of offsetleft keeps increasing, so the speed value also keeps decreasing.

Interview question 67 (Robot Motion scope) and question 67
Question: There is a square in M rows and N columns on the ground. A robot moves from the grid of coordinates (0, 0). Each time it moves a grid to the top, bottom, and left.
But cannot enter the grid where the sum of the numbers of the row and column coordinates is greater than k. For example, when k is 18, the robot can enter the grid ), because 3 + 5 + 7 + 3 = 18

How can I write a floating box compatible with all browsers (the floating box is always in the middle of the browser when it slides up or down )?
You can skip the search box. Or you can use a plug-in called All Search to make up for it.It seems to have something to do with the system setting in English. You can go to the google plug-in store to get an
