Yielding Processes(数组分块) 

 1 function chunk(array, process, context) {
 2     setTimeout(function() {
 3         var item = array.shift();
 4         process.call(context, item);
 5 
 6         if (array.length > 0) {
 7             setTimeout(arguments.callee, 100);
 8         }
 9     }, 100);
10 }
11 
12 var data = [12, 123, 1234, 453, 436, 23, 23, 5, 4123, 45, 346, 5634, 2234, 345, 342];
13 
14 function printValue(item) {
15     var div = document.getElementById("myDiv");
16     div.innerHTML += item + " <br/> ";
17 }
18 chunk(data, printValue);
19 //克隆一个数组
20 //chunk(data.concat(), printValue);
