每当我从子节点取消更新过程时，子节点只与根节点合并，我在控制台中找不到错误，或者我找不到任何可疑的东西。但重新加载后，一切都变得正常了
$(document).ready(function () {
var windowTemplate = kendo.template($("#windowTemplate").html());
var dataSource = new kendo.data.TreeListDataSource({
transport: {
read: {
url: "officeprofiletree",
type: 'POST',
dataType: "json"
},
update: {
url: "officeprofilenametree_update",
type: 'POST',
contentType :'application/json',
dataType: "json"
},
destroy: {
url: "officeprofilenametree_destroy",
type: 'POST',
contentType :'application/json',
dataType: "json"
},
parameterMap: function(options, operation) {
if (operation !== "read" && options.models)
{
return JSON.stringify(options.models);
}
}
},
batch: true,
sort: { field: "name", dir: "asc" },
schema: {
model: {
id: "officeProfileNMId",
parentId: "parentId",
fields: {
officeProfileNMId: { type:"number" },
parentId:{nullable:true,type:"number"},
mobile:{ type:"string"},
address:{type:"string"},
phone: {type:"string"},
},
}
}
});
var window = $("#window").kendoWindow({
visible:false,
title: "Are you sure you want to delete this record?",
width: "450px",
height: "60px",
}).data("kendoWindow");
var treelist = $("#treelist").kendoTreeList({
dataSource: dataSource,
pageable: true,
dataBound: function (){
var tree = this;
var trs = this.tbody.find('tr').each(function(){
var item = tree.dataItem($(this));
if( item.parentId == null) {
$(this).find('.k-button,.k-button').hide();
}
});
},
columns: [
{ field: "name", title: "Name"},
{ field: "mobile", title:"Mobile", format: "{0:c}", hidden: true },
{ field: "address", title:"Address",hidden: true },
{ field: "phone",title:"Phone" ,hidden: true },
{ command: [
{name: "edit"},
{name: "Delete",
click: function(e){
e.preventDefault();
var tr = $(e.target).closest("tr");
var data = this.dataItem(tr);
window.content(windowTemplate(data));
window.center().open();
$("#yesButton").click(function(){
treelist.dataSource.remove(data);
treelist.dataSource.sync();
window.close();
reloading();
})
$("#noButton").click(function(){
window.close();
})
}
}
]}
] ,
editable: {
mode: "popup",
},
}).data("kendoTreeList");
});
顺便说一下，更新和删除工作正常，这是小提琴 https://jsfiddle.net/me09jLy7/2/
更新用：
每当我创建一个ranikannur的孩子时，每个根ranikannur给我3个同名的孩子，在我的数据库中只有一个孩子是ranikannur的父级，但是treelist会显示它作为每个父节点中的3个子节点，子节点数3来自总ranikannur父节点（此处树具有3个ranikannur父节点）
我想这就是这三个孩子？
