Extjs 设置TreePanel CheckBox三态选中

由 ￡可爱￡侵袭症＋ 提交于 2020-02-29 21:55:06
对于TreePanel的Node我们需求是： 1.选中某个节点A的CheckBox，节点A的所有子节点全部选中； 2.节点A的所有子节点如果都选中，则A节点选中； 3.节点A的某些节点选中，某些节点不选中，则A节点处于半选状态。如下图所示： 如何来实现呢？研究发现TreePanel的节点的Checkbox可发现通过node.getUI().checkbox可以获取到checkbox。设置 checkbox的checked属性为true / false 可以设置checkbox选中或者非选择，那么三态的半选中状态如何设置呢？可以通过设置checkbox的indeterminate属性为 true，checked为false可以实现。因此，可以如下处理： Ext.Net HTMLCode <ext:TreePanel runat="server" ID="tree" RootVisible="false"> <Loader> <ext:TreeLoader DataUrl="/Home/GetNode"> <BaseParams> <ext:Parameter Name="pNodeId" Value="node.id" Mode="Raw"> </ext:Parameter> </BaseParams> </ext:TreeLoader> </Loader> <Root> <ext

Lets say the user adds new nodes to the tree and moves some nodes around. Is there away to get the JSON data from the tree so that it could be used for the next time the user loads the tree? EDIT (code solution) : Here is a solution

Treepanel with rootVisible = true not shown

由 ☆樱花仙子☆ 提交于 2019-12-13 16:03:58
问题 My tree is shown correctly when using rootVisible: false . However setting it to true leads to no tree display and no error. My aim is to show a root node that I can define as / or Root . How to achieve this? My solution: Putting rootVisible to true and adding this to my tree store: root: { id : '/', expanded : false, name : '/', type : 'folder', path : '/', root : true } 回答1: The name for the Rootnode is Root by default. But you can specify any other name. var store = Ext.create('Ext.data
