将json转换成struts参数的方法

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"
