jquery ajaxのバックグラウンドへの配列の受け渡しとバックグラウンドで配列を受け取る方法の詳細なコード説明

public class Person {

var as = []; 
var temp = []; 
for ( var int = 0; int < 5; int++) {

temp.push(&#39;,"v":&#39;); 
temp.push(int); 
temp.push(&#39;}&#39;); 
as.push(temp.join("")); 
} 
//Jquery中的方法，具体参考Jquery API 
$.post( "servlet/AjaxServlet?m=putWarningRule",{"aa":as} );

{"k":0,"v":0}

Enumeration<String> names = request.getParameterNames();
