element-ui tree组件注意事项
- node-key? 每个树节点用来作为唯一标识的属性，整棵树应该是唯一的
check-strictly? ?在显示复选框的情况下，是否严格的遵循父子不互相关联的做法，默认为 false
expand-on-click-node? ?是否在点击节点的时候展开或者收缩节点， 默认值为 true，如果为 false，则只有点箭头图标的时候才会展开或者收缩节点。
check-change? ?节点选中状态发生变化时的回调，共三个参数，依次为：传递给?
data?属性的数组中该节点所对应的对象、节点本身是否被选中、节点的子树中是否有被选中的节点props
role.vue模块

-
查询数据
submitForm(ruleForm) {
this.$refs[ruleForm].validate(valid => {
if (valid) {
this.pagination.page = 1;
this.getRolePageFun();
} else {
console.log("error submit!!");
return false;
}
});
},-
重置数据
resetForm(ruleForm) {
this.pagination.page = 1;
this.$refs[ruleForm].resetFields();
(this.ruleForm.roleName = ""),
(this.ruleForm.id = ""),
(this.ruleForm.disable = ""),
(this.ruleForm.pageNum = 1);
this.ruleForm.pageSize = this.pagination.pageSize;
this.getRolePageFun();
},- ?选择一页几条数据
handleSizeChange(val) {
this.pagination.pageSize = val;
this.pagination.page = 1;
this.getRolePageFun();
},-
选择第几页
handleCurrentChange(val) {
this.pagination.page = val;
this.getRolePageFun();
},-
权限设置
handleLimitClick(val) {
this.dialogFormUser = true;
},-
启用和禁用角色
handleDisableClick(row) {
console.log(row, "row");
