EasyUI Introduction

easyui is a collection of user interface plug-ins based on jQuery.

easyui provides the necessary functionality for creating modern, interactive, JavaScript applications.

Using easyui, you don’t need to write a lot of code. You only need to define the user interface by writing some simple HTML tags.

easyui is a complete framework that perfectly supports HTML5 web pages.

easyui saves the time and scale of your web development.

easyui is very simple but powerful.

It’s the first time for a newbie to use it. I still took some detours by referring to the methods introduced in the forum and recorded the problems I encountered.

1. The root node must be defined;

2. One or more root nodes can be used;

4. The parent node attribute of the root node does not need to be defined, or is defined as 0;

5. The parent node attribute name of child nodes at all levels must be "_parentId", and other names cannot be used. This name has been defined in jquery.easyui.js;

6. It is not necessary to output the json data of "tree" structure in the background ACTION . As long as the json of the following structure is given to the treegrid in the front desk, the tree shape can be established and output to the page. (I learned that outputting the children in tree format in the background is also an option.)

{"total":17,"rows":[
{"id":3,"goodsid":36120,"Qty":2.0000,"Rem":"15"},{"id":4,"goodsid":36123,"Qty":1.0000,"Rem":"21"},{"id":5,"goodsid":36124,"Qty":2.0000,"Rem":"23"},{"id":8,"goodsid":36130,"Qty":1.0000,"Rem":"1"},{"id":9,"goodsid":36131,"Qty":1.0000,"Rem":"2"},{"id":10,"goodsid":36132,"Qty":1.0000,"Rem":"3"},{"id":11,"goodsid":36133,"Qty":1.0000,"Rem":"4"},{"id":12,"goodsid":36134,"_parentId":8,"Qty":1.0000,"Rem":"1"},{"id":13,"goodsid":36135,"_parentId":8,"Qty":2.0000,"Rem":"2"},{"id":14,"goodsid":36136,"_parentId":8,"Qty":1.0000,"Rem":"3"},{"id":15,"goodsid":36137,"_parentId":8,"Qty":1.0000,"Rem":"4"},{"id":16,"goodsid":36138,"_parentId":8,"Qty":3.0000,"Rem":"5"},{"id":17,"goodsid":36139,"_parentId":8,"Qty":1.0000,"Rem":"6"},{"id":18,"goodsid":36142,"_parentId":9,"Qty":1.0000,"Rem":"1"},{"id":19,"goodsid":36143,"_parentId":9,"Qty":1.0000,"Rem":"2"},{"id":20,"goodsid":36144,"_parentId":9,"Qty":1.0000,"Rem":"3"},{"id":21,"goodsid":36145,"_parentId":9,"Qty":1.0000,"Rem":"4"}

This is Action

var pls = ListAll(p.PartChild).ToList();
List<Object> result = new List<object>();
foreach(var item in pls)
{
if(item.PartParent == p.PartChild)
{
result.Add( new { id = item.ListID, goodsid = item.PartChild, Qty = item.Qty, Rem = item.Rem });
//下面是调用生成树形数据方法的语句,多余！easyui可根据parentID自动建树
//Object l = new { id = item.ListID, text = item.PartChild, _parentId = 0,Qty = item.Qty, Rem = item.Rem, chlidren = TreeList(pls, item.PartChild) };
//result.Add(l);
}
else
{
var parent = from a in pls
where a.PartChild == item.PartParent
select a;
result.Add(new { id = item.ListID, goodsid = item.PartChild, _parentId = parent.First().ListID, Qty = item.Qty, Rem = item.Rem });
}
