我想送User对象转化为行动的清单,而用户字段的名称和地址在这里。
I want to send a list of User object into action, while user has field name and address here.
有些code这样的:网页是动态的jQuery操纵。有样本$ C $网页℃。
Some code like this: The webpage is dynamic manipulated by jquery. there is sample code of webpage.
<form id="create">
<tr id="1"> <td> <input type='text' name='name'/></td><td><input type='text' name='address'/></td></tr>
<tr id="3"> <td> <input type='text' name='name'/></td><td><input type='text' name='address'/></td></tr>
</form>
<input type='submit' onclick="submit()"/>
<script>
function submit() {
var results = [];
$("#create tr").each(function(index, tr) {
var user = {
name: tr.find('input[name="name"]').val(),
address: tr.find('input[name="address"]').val()
}
results.push(user);
});
var param = {users:results};
$.ajax({
url: "save.action",
data: param,
type: 'post',
success: function() {
alert('success');
},
error: function() {
alert('error');
}
});
}
</script>
行动code是这样的:
Action code like this:
@ParentPackage('json-default')
public class UserAction extends ActionSupport {
private List<User> users;
public List<User> getUsers(){
return users;
}
public void setUsers(List<User> users){
this.users = users;
}
@Action(name="save", results={@Result{name="success",location="/webpage/addUser.jsp"}})
public String execute(){
for(User user: Users){
System.out.println(user.getName()+" address: "+ user.getAddress());
}
return SUCCESS;
}
}
我的问题是为什么动作不能接收数据? 我从萤火虫采集数据和数据已经公布。 因此,任何提示或什么事吗? 我两天时间被搞糊涂了,请大家帮忙。
My question is why the action can't receive the data? I capture the data from firebug and the data has been posted. So any hint or something wrong? I was confused here two days, please help.
如果您使用jQuery 1.4你应该考虑有一个关于参数序列化的变化。 jQuery提供了一个新的标志$就来覆盖默认行为(和回用参数序列化的老方法):在$就传统的选项,所以,你应该尝试的超过阿贾克斯JQuery的发送数据:
If you use jQuery 1.4 you should consider that there is a change about param serialization. JQuery provides a new flag in $.ajax to override the default behavior (and go back to use the old way of param serialization): the "traditional" option in $.ajax So you should try that to send data over Ajax at JQuery:
....
$.ajax({
url:"save.action",
data:param,
type:'post',
traditional: true,
....
