我尝试“发布”数据,但是当我这样做时,我收到错误 400。我对“更新”数据有同样的问题。我不知道如何解决这个问题。
这是我的 jqgrid 代码: $(function() {
$.extend($.jgrid.defaults, {
datatype: 'json',
jsonReader : {
repeatitems:false,
total: function(result) {
//Total number of pages
return Math.ceil(result.total / result.max);
},
records: function(result) {
//Total number of records
return result.total;
}
},
prmNames: {
rows: 'max',
search: null
},
height: 'auto',
viewrecords: true,
rowList: [10, 20, 50, 100],
altRows: true,
loadError: function(xhr, status, error) {
alert(error);
}
});
$.extend($.jgrid.edit, {
closeAfterEdit: true,
closeAfterAdd: true,
ajaxEditOptions: {
contentType: "application/json"
},
mtype: 'PUT',
serializeEditData: function(data) {
delete data.oper;
return JSON.stringify(data);
}
});
$.extend($.jgrid.del, {
mtype: 'DELETE',
serializeDelData: function() {
return "";
}
});
var editOptions = {
onclickSubmit: function(params, postdata) {
params.url = URL + '/' + postdata.id;
}
};
var addOptions = {
mtype: "POST"
};
var delOptions = {
onclickSubmit: function(params, postdata) {
params.url = URL + '/' + postdata;
}
};
var URL = 'rest/poll';
var options = {
url: URL,
editurl: URL,
colModel:[
{
name:'id',
label: 'ID',
formatter:'integer',
width: 40,
editable: true,
editoptions: {
disabled: true,
size:5
}
},
{
name: 'categories.name',
index: 'categories',
label: 'Category',
editable: true,
edittype: "select",
viewrecords:true,
editoptions: {
dataUrl:"rest/category/list.do",
buildSelect: function (list)
{
var data = jQuery.parseJSON(list);
var s = '<select>';
for (var i = 0; i < data.locationList.length; i++) {
s += '<option value="' + data.locationList[i] + '">' + data.locationList[i].name + '</option>';
}
return s + "</select>";
}
}
},
{
name:'name',
label: 'Name',
width: 300,
editable: true,
editrules: {
required: true
}
},
{
name: 'MyLink',
formatter: myLinkFormatter
}
],
caption: "Polls",
pager : '#pager',
height: 'auto',
ondblClickRow: function(id) {
jQuery(this).jqGrid('editGridRow', id, editOptions);
}
};
$("#grid")
.jqGrid(options)
.navGrid('#pager',
{}, //options
editOptions,
addOptions,
delOptions,
{} // search options
);
});
function myLinkFormatter (cellvalue, options, rowObjcet) {
return '<a href = "/Polls_V2/options?categoryId=' + options.rowId + '">Answers</a>';
}
这是我的控制器代码:
@RequestMapping(method = RequestMethod.POST)
public ResponseEntity<String> createCategory(HttpServletRequest request, @RequestBody Polls polls) {
pollsService.add(polls);
URI uri = new UriTemplate("{requestUrl}/{username}").expand(request.getRequestURL().toString(), polls.getId());
final HttpHeaders headers = new HttpHeaders();
headers.put("Location", Collections.singletonList(uri.toASCIIString()));
return new ResponseEntity<String>(headers, HttpStatus.CREATED);
}
