Spread实例销毁后，Vue的组件销毁时报错

收藏

代码：

beforeRouteLeave (to, from, next) {
this.$refs.monthSpreadJS.spread.destroy()
this.$destroy()
}

复制代码

如果只执行

this.$destroy()

复制代码

的话，内存并不会被释放。

错误日至

您好，请问您的SpreadJS版本号多少？V11曾修复过一个内存泄漏的问题，

推荐您先把SpreadJS升级到最新版本再尝试。

如果仍有问题，请提供一个能够重现问题的示例包，上传到帖子附件。

您好，我们以您的方式创建了VUE的示例项目，没能重现这个问题，请参考附件。
附件中的示例项目，解压后需要先执行

npm install

再执行：

npm start

按照您的方式，在VueSampleV1210\src\components\QuickStart.vue中定义了beforeRouteLeave方法。

找到原因了。。
我在全局定义了一个方法。。刚才把它删了之后就好了。。。

GC.Spread.Sheets.Workbook.prototype.XXXXX
