我已经在JavaScript
VAR数据=新的对象();
和一些属性此对象是:
data.name =迈克;
data.id = 1;
使用jQuery的对象传递给一个JSP页面
VAR请求= $阿贾克斯
({
网址:test.jsp的,
类型:后,
数据:'OBJ ='+的数据,
成功:函数(MSG){
$('#响应)HTML(味精);},
错误:函数(XHR,ajaxOptions,thrownError){
警报(xhr.status);
警报(thrownError);
}
});

在JSP我说
对象objParam =的request.getParameter(目标文件);
通过out.println(objParam.name);
这似乎并没有工作。请大家帮忙。
解决方案 因为你张贴到JSP,请确保您处理的doPost(请求,响应)
方法内。
一般情况下,通过了所有的数据应该是JSON格式。你的情况,就应该读
数据:{OBJ:数据}
要分析在服务器端,使用 org.json 库:
JSONObject的OBJ =(的JSONObject)JSONValue.parse(的request.getParameter(目标文件));
迭代器<>键= obj.keys();
//遍历JSON对象的属性
而(keys.hasNext()){
字符串键=(字符串)keys.next();
如果(obj.get(密钥)的instanceof的JSONObject){
//一个的JSONObject中的JSONObject内
} 其他 {
//处理
}
}
请参阅文档: 的JSONObject
i have in javascript
var data = new Object();
and some attributes for this object are:
data.name = "mike";
data.id = 1;
i use jquery to pass the object to a jsp page
var request = $.ajax
({
url: "test.jsp",
type: "post",
data: 'obj='+ data,
success: function(msg) {
$('#response').html(msg);},
error:function (xhr, ajaxOptions, thrownError){
alert(xhr.status);
alert(thrownError);
}
});
in the jsp i say
Object objParam = request.getParameter("obj");
out.println(objParam.name);
this doesn't seem to work. please help.
解决方案 Because you are posting to the JSP, make sure that you handle inside adoPost(request, response)
method.
Generally, all data passed should be in JSON format. In your case, it should read
data: {'obj' : data}
To parse on the server side, use the org.json library:
JSONObject obj = (JSONObject) JSONValue.parse(request.getParameter("obj"));
Iterator<?> keys = obj.keys();
//iterate over the properties of the JSON object
while( keys.hasNext() ){
String key = (String)keys.next();
if( obj.get(key) instanceof JSONObject ){
//a JSONObject inside the JSONObject
} else {
//process
}
}
See the docs: JSONObject
