我正在尝试使用 ajax 和 jquery 编写 spring mvc 应用程序,并且自上周以来一直卡在某个时间点并且无法找到解决方案。请帮帮我。
我想发送请求以使用 ajax 在数据库中显示我的所有用户,看看我是怎么做的
显示用户列表
现在 javascript ajax 请求
function doAjaxPost(id)
{ var submitId=id;
if(submitId=="showUserList")
{
$.ajax({
type: "POST",
url: "showUserList.html",
success: function(response){
// we have the response
if(response!='')
{
//alert(response);
//Not getting this $('#listofUser').html(response);
$("#homeDiv").hide();
$("#userListDiv").show("5");
}
},
error: function(e){
alert('Error: ' + e);
}
});
}
}
现在见我控制器
@RequestMapping(value="/showUserList",method = RequestMethod.POST)
public @ResponseBody ModelMap showUserList()
{
System.out.println("Ajax Request For user List");
List<UserDetails> userList=service.getAllUser();
ModelMap model=new ModelMap();
model.put("users", userList);
return model;
}
现在看看我如何在 jsp 页面上显示用户列表
<div id="listofUser">
<c:if test="${!empty users}">
<table id="rounded-corner" summary="List Of System Users">
<thead>
<tr>
<th scope="col" class="rounded-select">Select</th>
<th scope="col" class="rounded-id">ID</th>
<th scope="col" class="rounded-fname">Name</th>
<th scope="col" class="rounded-gender">Gender</th>
<th scope="col" class="rounded-username">UserName</th>
<!-- <th scope="col" class="rounded-password">Password</th> -->
<th scope="col" class="rounded-usertype">Type</th>
<th scope="col" class="rounded-userStatus">Status</th>
<th scope="col" class="rounded-Email">Email</th>
<th scope="col" class="rounded-address">Address</th>
<th scope="col" class="rounded-phno">PhoneNo.</th>
</tr>
</thead>
<form action="adminOperations.html" name="userListForm" onsubmit="return ConfirmOperation();" method="post">
<tbody>
<c:forEach items="${users}" var="users" varStatus="status">
<tr>
<td><input type="checkbox" value="${users.id}" id="select" name="select"/></td>
<td><c:out value="${users.id}" /></td>
<td><c:out value="${users.firstName}" /> <c:out value="${users.lastName}" /></td>
<td><c:out value="${users.gender}" /></td>
<td><c:out value="${users.userName}" /></td>
<%-- <td><c:out value="${users.userPassword}" /></td> --%>
<td><c:out value="${users.userType}" /></td>
<td><c:out value="${users.status}" /></td>
<td><c:out value="${users.emailId}" /></td>
<td><c:out value="${users.address}" /></td>
<td><c:out value="${users.contactNo}" /></td>
</tr>
</c:forEach>
</tbody>
<tfoot>
<tr>
<td colspan="12" class="rounded-foot-center" align="center">
<input type="submit" name="activate" id="activate" value="Activate" onClick="ButtonClicked(this);">
<input type="submit" name="deactivate" id="deactivate" value="Deactivate" onClick="ButtonClicked(this);">
<input type="submit" name="update" id="update" value="Update" onclick="ButtonClicked(this);">
<input type="submit" name="delete" id="delete" value="Delete" onclick="ButtonClicked(this);">
</td>
</tr>
</tfoot>
</form>
</table>
<br/>
</c:if>
<c:if test="${empty users}">
There are currently no user found.
</c:if>
</div>
..................................................... .....................我没有得到的是,当响应来自控制器(在我的情况下为 ModelMap 对象)时,我将如何将包含用户列表的模型传递给我的jsp页面,以便它可以显示。我试过
$('#listofUser').html(response); 但它不起作用,我希望包含 (model.put("users", userList);)用户的模型可以从 javascript 访问我的显示部分..请帮帮我.....谢谢和问候,Hemant Singh
