你的代码是错误的,你在搞砸事情,如果你想使用jQuery
和ajax
调用,那么不要ModelAndView
在你的Spring
控制器中使用。取而代之的是,使用以下内容和return
您的bean
ordto
作为json
usingJackson
库Java
:
将其包含jar
在您的lib
项目文件夹中:
http://www.java2s.com/Code/JarDownload/jackson/jackson-all-1.9.9.jar.zip
Java代码:
@RequestMapping(value = "businessBill.htm", method = RequestMethod.POST)
@ResponseBody
public String handleBusinessBillDetails(@RequestParam("reference") String billReference, @RequestParam("invoiceDate") String billDate,
HttpServletRequest request, HttpServletResponse response) {
String json = null;
try {
//1. Create 'jackson' object mapper
ObjectMapper objectMapper = new ObjectMapper();
BusinessBillDTO businessBillDTO = new BusinessBillDTO();
businessBillDTO.setBillDate(sdf.parse(billDate));
businessBillDTO.setBillReference(billReference);
BusinessBillDTO billDto = accountStatementBO.getBusinessBillDetails(businessBillDTO);
//2. Convert your 'bean' or 'dto' as 'json' string
json = objectMapper.writeValueAsString(billDto);
} catch (Exception ex) {
LOGGER.error(ex);
}
return json;
}
然后,Table.jsp
将div
used in Dialog.jsp
as放入hidden
,这将是您modal
将来的对话框(请注意,span
标签中也有一些更改):
<div id="BusinessBill" style="display:none;">
<h2>Bill Details</h2>
<em>Business Ltd</em>
<div class="row">
<span class="spanAsLabel">Account number</span>
<span id="dlg-account-number" class="spanAsLabel"></span>
</div>
<div class="row">
<span class="spanAsLabel">Bill date</span>
<span id="dlg-bill-date" class="spanAsLabel"></span>
</div>
</div>
现在像这样修复你的getBusinessBill(..)
方法:
您还可以使用$.ajax
并且可能处理更多状态,例如onerror
和其他,但这种方式更简单(至少对我而言,您只需要评估返回data
的是否是null
,并让知道user
-如果null
- 发生了某事server
,可能会显示alert
带有通用消息)-请阅读评论。
function getBusinessBill(billReference, billInvoiceDate) {
$.post("/AccountStatement/businessBill.htm", {
reference: billReference,
invoiceDate: billInvoiceDate
}, function (data) {
/* You can implement more validations for 'data', in my case I just used these 'if' conditionals but can vary. */
if(data != null) { //returned 'data' is not 'null'
/* parse 'data' as 'json' object
* will be good to console.log(data) and take a look. */
var obj = $.parseJSON(data);
if(obj != {}) { //check if 'data' is not an empty 'json' object once transformed
//set the 'data' in the dialog
$('#dlg-account-number').text(obj.accountNumber);
$('#dlg-bill-date').text(obj.billDate);
/* open modal dialog, you can simulate it this way (for this case)
* but the correct way is to use 'jquery-ui' dialog or any plugin you prefer.
* At this point you will see the hidden 'div' in a visible way with your 'data'.
*/
$('#BusinessBill').fadeIn();
} else {
//show 'generic' message
alert('No results found.');
}
} else {
//show 'generic' message
alert('An error occurred, try again.');
}
});
}
最后,如果一切正确,您将在同一页面 ( Table.jsp
) 上看到modal
与您的对话框data
,所有这些都是通过ajax
调用避免重定向页面(如 ( Table.jsp
to => Dialog.jsp
))。
