bootstrap-treeview 如何实现全选父节点下所有子节点及反选

function getChildNodeIdArr(node) {
var ts = [];
if (node.nodes) {
for (x in node.nodes) {
ts.push(node.nodes[x].nodeId);
if (node.nodes[x].nodes) {
var getNodeDieDai = getChildNodeIdArr(node.nodes[x]);
for (j in getNodeDieDai) {
ts.push(getNodeDieDai[j]);
}
}
}
} else {
ts.push(node.nodeId);
}
return ts;
}

function setParentNodeCheck(node) {
var parentNode = $("#treeview-checkable").treeview("getNode", node.parentId);
if (parentNode.nodes) {
var checkedCount = 0;
for (x in parentNode.nodes) {
if (parentNode.nodes[x].state.checked) {
checkedCount ++;
} else {
break;
}
}
if (checkedCount === parentNode.nodes.length) {
$("#treeview-checkable").treeview("checkNode", parentNode.nodeId);
setParentNodeCheck(parentNode);
}
}
}
