Question

ajax上传 data数据 后台接收为空

data : {
'number' : $("#number").text()
},

后台接收不到 把属性名改成number1就能接收到值
data : {
'number1' : $("#number").text()
},
这是为什么
前后台都是number 后台就接收不到值

前后台都改成number1 后天就能接收到值
很奇怪。。。

var url = "";
var data = {"param":"我是参数","other":"me too"};
$.post(url,data,function(result){

});

private String param;
private String other;
public void Test(){
PrintWriter out = null;
try{
out = getResponse().getWriter();
if(param.equals("我是参数")){
out.print(other);
}
}catch(Exception e){

}finally{
out.flush();
out.close();
}
}
