将json转换成struts参数

加入对象为{name:'tom','class':{className:'class1'},classMates:[{name:'lily'}]}
struts2期待的格式是 name=tom&class.className=class1&classMates[0].name=lily

function parseParam(param, key) {
var paramStr = "";
if (param instanceof String || param instanceof Number || param instanceof Boolean
) {
paramStr += "&" + key + "=" + encodeURIComponent(param);
}
else {
$.each(param, function (i, p) {
if (p == null || p == undefined)
return true;
var k = key == null ? i : key + (param instanceof Array ? "[" + i + "]" : "." + i);
paramStr += '&' + parseParam(this, k);
});
}
return paramStr.substr(1);
};

//调用：
var obj={name:'tom','class':{className:'class1'},classMates:[{name:'lily'}]};
parseParam(obj);
//结果：
"name=tom&class.className=class1&classMates[0].name=lily"
parseParam(obj,'stu');
//结果：
"stu.name=tom&stu.class.className=class1&stu.classMates[0].name=lily"
