lyuehh / timeout.js
Created December 27, 2013 02:30
var a = 1; // 全局变量
function b(){
a = 2; // 没有var, 就是全局, a变成2了
console.log(a); // 输出2
a = 3; // a变成3了
setTimeout(function(){ //只要是setTimeout, 它就会异步执行, 就算延迟0秒也会异步, 所以这里不会执行了
console.log(a);
}, 0);
a = 4; // 修改a为4

Lightbox Widget

An example of a famo.us lightbox widget. The lightbox flips between thumbnail and detail view when an item is clicked. Edit the grid layout using the sliders. Animations are powered by both easing curves and physics animations.

A Pen by famo.us on CodePen.

Click in the open space to add a node, drag from one node to another to add an edge.
Ctrl-drag a node to move the graph layout.
Click a node or an edge to select it.

When a node is selected: R toggles reflexivity, Delete removes the node.
When an edge is selected: L(eft), R(ight), B(oth) change direction, Delete removes the edge.
