我无法使用(ajaxFileUpload)进行上传,但我无法使其正常工作。我正在关注这篇文章,但没有调用 UploadImage 函数。我的意思是,似乎 afterSubmit 事件没有被触发。
任何想法为什么?
jQuery("#ajaxGrid").jqGrid({
url: $("#ServiceUrl").val(),
datatype: "json",
jsonReader: { repeatitems: false, id: "Id" },
colNames: ['Id', 'logoTarjeta'],
colModel: [
{ name: 'Id', index: 'id', editable: false, sortable: true, hidden: true, align: 'left' },
{
name: 'FileToUpload', index: 'logo', editable: true, edittype: 'file',
editoptions: {
enctype: "multipart/form-data"
},
width: 210, align: 'center', /*formatter: jgImageFormatter,*/ search: false
}
],
prmNames: { nd: null, search: null, page: "pageNumber", rows: "pageSize", sort: "sortColumn", order: "sortDirection" },
mtype: 'GET',
rowNum: 15,
pager: '#ajaxGridPager',
rowList: [10, 20, 50, 100],
imgpath: $("#ServiceImagesUrl").val(),
multiselect: false,
scrollOffset: 0,
afterSubmit: UploadImage,
error: function (x, e) {
alert(x.readyState + " " + x.status + " " + e.msg);
}
});
function updateDialog(action) {
return {
url: $("#ServiceUrl").val(),
closeAfterAdd: true,
closeAfterEdit: true,
afterShowForm: function (formId) { },
modal: true,
onclickSubmit: function (params) {
var list = $("#ajaxGrid");
var selectedRow = list.getGridParam("selrow");
params.url += "/" + list.getRowData(selectedRow).Id;
params.mtype = action;
},
width: "400",
ajaxEditOptions: { contentType: "application/json" },
serializeEditData: function (data) {
delete data.oper;
return JSON.stringify(data);
}
};
}
jQuery("#ajaxGrid").jqGrid(
'navGrid',
'#ajaxGridPager',
{
add: true,
edit: true,
del: true,
search: false,
refresh: false
},
updateDialog('PUT'),
updateDialog('POST'),
updateDialog('DELETE')
);
$(window).resize(resize_the_grid);
function resize_the_grid() {
$('#ajaxGrid').fluidGrid({ base: '#grid_wrapper', offset: -20 });
}
function UploadImage(response, postdata) {
debugger;
var data = $.parseJSON(response.responseText);
if (data.success == true) {
if ($("#fileToUpload").val() != "") {
ajaxFileUpload(data.id);
}
}
return [data.success, data.message, data.id];
}
function ajaxFileUpload(id) {
$("#loading")
.ajaxStart(function () {
$(this).show();
})
.ajaxComplete(function () {
$(this).hide();
});
$.ajaxFileUpload(
{
url: $("#UploadImageUrl").val(),
secureuri: false,
fileElementId: 'fileToUpload',
dataType: 'json',
data: { id: id },
success: function (data, status) {
if (typeof (data.success) != 'undefined') {
if (data.success != true) {
return alert(data.message);
}
return true;
} else {
return alert('Failed to upload logo!');
}
},
error: function (data, status, e) {
return alert('Failed to upload logo!');
}
}
);
}
这是提交时调用的 webapi 服务
public HttpResponseMessage Put(Type type)
{
if (ModelState.IsValid)
{
Uow.Types.Update(type);
Uow.Commit();
var resp = new HttpResponseMessage
{
Content = new StringContent("{\"success\":true,\"message\":\"\",\"new_id\":\"\"}")
};
resp.Content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
//resp.StatusCode = HttpStatusCode.NoContent;
return resp;
}
throw new HttpResponseException(HttpStatusCode.BadRequest);
}
我看到网页中加载了插件 javascript。
提前致谢!吉列尔莫。
