一. 不展示子節點

效果圖


這個只要在你返回給前臺的資料型別中加一個欄位就好：state：“closed”
假如下面是你返回的資料型別：

{"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}
]}
 

你只要給的父節點加一個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.更改樹形表格預設圖示

其實這個和讓表格初始化不展示子節點是一樣的，要在返回的型別中加上欄位：“iconCls”:“icon-add”:

請注意·：這個"con-add"是預設可以選擇的,由自己定義
