Question

Extjs4.1怎么给tree的每个节点都加上复选框

Answer 1

在store加checked属性
var store = Ext.create('Ext.data.TreeStore', {
root: {
expanded: true,
children: [
{ text: "detention", leaf: true, checked: true },
{ text: "homework", expanded: true, children: [
{ text: "book report", leaf: true },
{ text: "algebra", leaf: true, checked: false}
] },
{ text: "buy lottery tickets", leaf: true }
]
}
});
