easyui 树形表格初始化不展示子节点与更改图标

一. 不展示子节点

效果图


这个只要在你返回给前台的数据类型中加一个字段就好：state：“closed”
假如下面是你返回的数据类型：

{"total":9,"rows":[
	{"id":1,"region":"Wyoming"},
	{"id":11,"region":"Albin","_parentId":1},
	{"id":12,"region":"Canon","_parentId":1},
	{"id":13,"region":"Egbert","_parentId":1},
	{"id":2,"region":"Washington"},
	{"id":21,"region":"Bellingham","_parentId":2},
	{"id":22,"region":"Chehalis","_parentId":2},
	{"id":23,"region":"Ellensburg","_parentId":2},
	{"id":24,"region":"Monroe","_parentId":2}
]}

你只要给的父节点加一个state：“closed”`就好，如：

{"total":9,"rows":[
	{"id":1,"region":"Wyoming","state":"closed"},
	{"id":11,"region":"Albin","_parentId":1},
	{"id":12,"region":"Canon","_parentId":1},
	{"id":13,"region":"Egbert","_parentId":1},
	{"id":2,"region":"Washington","state":"closed"},
	{"id":21,"region":"Bellingham","_parentId":2},
	{"id":22,"region":"Chehalis","_parentId":2},
	{"id":23,"region":"Ellensburg","_parentId":2},
	{"id":24,"region":"Monroe","_parentId":2}
]}

二.更改树形表格默认图标

其实这个和让表格初始化不展示子节点是一样的，要在返回的类型中加上字段：“iconCls”:“icon-add”:

请注意·：这个"con-add"是默认可以选择的,由自己定义
