Javascript冒泡排序算法详解

function sort(elements){
  for(var i=0;i<elements.length-1;i++){
    for(var j=0;j<elements.length-i-1;j++){
      if(elements[j]>elements[j+1]){
        var swap=elements[j];
        elements[j]=elements[j+1];
        elements[j+1]=swap;
      }
    }
  }
}

var elements = [3, 1, 5, 7, 2, 4, 9, 6, 10, 8];
console.log('before: ' + elements);
sort(elements);
console.log(' after: ' + elements);
