1、快速排序：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>快速排序</title>
</head>
<body>
<script>
var ary=[21,8,4,32,5];
function quickSort(ary){
if(ary.length<=1){
return ary;
}
var num=Math.floor(ary.length/2);
var numValue=ary.splice(num,1)[0];
var left=[];
var right=[];
for(var i=0; i<ary.length; i++){
var cur=ary[i];
if(cur<numValue){
left.push(cur);
}else{
right.push(cur);
}
}
return quickSort(left).concat([numValue],quickSort(right));
}
document.write(quickSort(ary));
</script>
</body>
</html>
2、插入排序
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>插入排序</title>
</head>
<body>
<script>
var ary=[21,8,4,32,5];
function insertSort(ary){
var left=ary.splice(0,1);
for(var i=0; i<ary.length; i++){
var cur=ary[i];
for(var j=left.length-1; j>=0;){
var nex=left[j];
if(cur<nex){
j--;
if(j===-1){
left.unshift(cur);
}
}else{
left.splice(j+1,0,cur);
break;
}
}
}
return left;
}
document.write(insertSort(ary));
</script>
</body>
</html>
3、冒泡排序
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>冒泡排序</title>
</head>
<body>
<script>
var ary=[21,32,2,9,4];
function bubbleSort(ary){
for(var i=0; i<ary.length; i++){
for(var j=0; j<ary.length-i-1; j++){
if(ary[j]>ary[j+1]){
var tmp=ary[j+1];
ary[j+1]=ary[j];
ary[j]=tmp;
}
}
}
return ary;
}
document.write(bubbleSort(ary));
</script>
</body>
</html>
