先看图：
代码如下：
// 全部选中
qxClick() {
this.isQx = !this.isQx;
// 判断按钮的状态
this.expandAll();
if (this.isQx) {
console.log(this.isQx, "-------------------------------", this.datas);
// 设置
this.$refs.treeForm_mxs.setCheckedNodes(this.datas);
for (
var i = 0;
i < this.$refs.treeForm_mxs.getCheckedNodes().length;
i++
) {}
} else {
this.$refs.treeForm_mxs.setCheckedNodes([]);
}
},
// 全部展开
expandAll() {
if (this.isQx) {
for (var i in this.$refs.treeForm_mxs.store.nodesMap) {
this.$refs.treeForm_mxs.store.nodesMap[i].expanded = true;
}
} else {
for (var j in this.$refs.treeForm_mxs.store.nodesMap) {
this.$refs.treeForm_mxs.store.nodesMap[j].expanded = false;
}
}
},
