在节点中加上"checked"属性，会自动生成checkBox。
获取选中节点
rush:js;">
var nodeArray = "";
var nodesObj = mytree.getChecked();
var i;var length=nodesObj .length;
for (i = 0; i < length; i++) {
nodeArray += nodesObj[i].id + ','; //允许多选的情况。如果不允许多选，就直接nodesObj[i].id
}
nodeArray = nodeArray.substring(0,nodeArray.length - 1);
Json格式如下：
rush:plain;">
[{
"text": "To Do","cls": "folder","expanded": true,"children": [{
"text": "Go jogging","leaf": true,"checked": true
},{
"text": "Take a nap","checked": false
},{
"text": "climb Everest","checked": false
}]
},{
"text": "Grocery List","children": [{
"text": "Bananas",{
"text": "Milk",{
"text": "Cereal",{
"text": "Energy foods","children": [{
"text": "Coffee",{
"text": "Red Bull","checked": false
}]
}]
},{
"text": "Remodel Project","children": [{
"text": "Finish the budget",{
"text": "Call contractors",{
"text": "Choose design","checked": false
}]
}]
