我的 Kendo 数据网格组件有问题。
我正在尝试将新行添加到网格中并通过创建事件创建对 API 的远程请求。
问题是，如果我尝试在第一个请求后添加新行，Kendo 会发出 2 个请求，而不是一个。
我尝试使用 Transport create 和 options.success 方法找到一些解决方案，但没有运气。
http://docs.telerik.com/kendo-ui/api/framework/datasource#configuration-transport.create
有人可以告诉我我做错了什么吗？
感谢您的帮助。
这是创建服务器响应的代码:
+ Response 200 (application/json)
{
"status": "OK",
"result":[
{
"id":22,
"username":"blahblah",
"name":"Thomas",
"surname":"Man",
"email":"to.mas.marny@gmail.com",
"created":"1399986964",
"role":"USER"
}
]
}
该方法的代码如下:
$scope.initGrid = function () {
// get access token from localstorage
var token = localStorage
.getItem($rootScope.lsTokenNameSpace);
// set pagination data
var paginationData = {
"token": token,
"data": {
"page": 1,
"items_per_page": 20
}
};
var dataPacket;
dataPacket = new kendo.data.DataSource({
transport: {
read: function (options) {
$.ajax({
url: $rootScope.apiBaseUrl + "user/list",
dataType: "json",
type: "POST",
data: JSON
.stringify(paginationData),
success: function (
response) {
console
.log("List of users succesfully obtained");
console
.log(response.result);
// pass response to
// model
options
.success(response);
// $notification.enableHtml5Mode();
},
error: function (error) {
console
.log("user list request error");
console.log(error);
$notification
.error(
"User list cannot be loaded",
"Please try again in a minute.");
}
});
},
update: function (options) {
console.log("Update");
options
.success("{\"test\":\"test\"}");
},
destroy: function (options) {
console.log("destroy");
options
.success("{\"test\":\"test\"}");
},
create: function (options) {
console.log("Create");
console.log(options.data);
$.ajax({
url: $rootScope.apiBaseUrl + "user/create",
dataType: "json",
type: "POST",
data: JSON
.stringify(options.data),
success: function (
response) {
console
.log("New user created");
console
.log(response.status);
// pass response to
// model
options
.success(response.result);
// $notification.enableHtml5Mode();
},
error: function (error) {
console.log("user list request error");
console.log(error);
$notification
.error(
"User cannot be created",
"Please try again in a minute.");
}
});
},
parameterMap: function(options, operation) {
if (operation !== "read" && options.models) {
return {models: kendo.stringify(options.models)};
}
}
},
//batch : true,
//autoSync: true,
schema: {
data: "result",
model: {
id: "id",
fields: {
id: {
editable: false,
nullable: true
},
name: {
editable: true,
nullable: false
},
username: {
editable: true,
nullable: false
}
}
}
}
});
$("#grid").kendoGrid({
dataSource: dataPacket,
filterable: true,
pageSize: 20,
pageable: true,
height: 550,
toolbar: ["create", "save", "cancel"],
columns: ["id", "name", "username", {
command: ["edit", "destroy"],
title: " ",
width: "200px"
}],
editable: "inline"
});
};
最佳答案
- 如果您在模型内声明 id，则不必在模型字段内声明 id。
当您指向时也是如此
数据:“结果”
对于您必须通过的模型
options.success(response)
ajax 的 success 函数内部，而不仅仅是
options.success(response.result)
