把javascript的对象，转换为struts2 action的调用参数格式。以下为源码：
$.strutsParam = function(actionPropertyName, obj) {
var newObj = {};
strutsParam(actionPropertyName, obj, newObj);
return newObj;
//参数转换，递归函数
function strutsParam(actionPropertyName, obj, newObj) {
if (Array.isArray(obj)) {
var arr = obj;
for ( var i = 0; i < arr.length; i++) {
var arrItem = arr[i];
if (typeof (arrItem) == "object") {
//对象有属性
for ( var p in arrItem) {
var key = actionPropertyName + "[" + i + "]." + p;
if (Array.isArray(arrItem[p])) {
//对象为数组，递归
strutsParam(key, arrItem[p], newObj);
} else {
//console.log(typeof (arrItem[p]));
if (typeof (arrItem[p]) != "function") {
newObj[key] = arrItem[p];
}
}
}
} else {
//对象无属性
var key = actionPropertyName + "[" + i + "]";
//console.log(typeof (arrItem));
if (typeof (arrItem) != "function") {
newObj[key] = arrItem;
}
}
}
} else {
if (typeof (obj) == "object") {
for ( var p in obj) {
//console.log(typeof (obj[p]));
var key = actionPropertyName + "." + p;
if (typeof (obj[p]) != "function") {
newObj[key] = obj[p];
}
}
} else {
//对象无属性
var key = actionPropertyName;
//console.log(typeof (obj));
if (typeof (obj) != "function") {
newObj[key] = obj;
}
