mounted:function(){ this.patSex = this.patSex || this.defaultCard.patSex; this.patName = this.patName || this.defaultCard.patName; this.patAge = this.patAge || this.defaultCard.patAge; this.patRelation = this.patRelation || this.defaultCard.patRelation; this.patIdNo = this.patIdNo || this.defaultCard.patIdNo; this.queryCardInfo(); },

这段代码是在Vue.js中的一个组件中的生命周期钩子函数mounted中执行的。它首先会对this.patSex,this.patName,this.patAge,this.patRelation和this.patIdNo进行赋值操作,如果这些值为null或undefined,则会使用this.defaultCard中的对应属性值进行赋值。然后会调用this.queryCardInfo()函数查询患者的相关信息。

mounted: function () { this.loadTasks(); }
As an AI language model, I cannot provide the exact context for the code you have shared. However, based on the code snippet you have provided, it seems like it is a mounted lifecycle hook in a Vue.js component.
The mounted hook is a Vue.js lifecycle hook that is called when the component is mounted to the DOM. In this case, the mounted hook is calling the loadTasks() method, which is responsible for loading tasks into the component.
Overall, this code is likely part of a larger Vue.js component that is responsible for displaying tasks and is calling the loadTasks() method when it is mounted to the DOM to ensure that the tasks are loaded and displayed correctly.
this.$refs.scrollContainer.scrollTop = 200 不起作用
如果代码 `this.$refs.scrollContainer.scrollTop = 200` 没有起作用,可能存在以下几种情况:
1. `this.$refs.scrollContainer` 所引用的元素不存在,可以使用 `console.log(this.$refs.scrollContainer)` 查看控制台是否有输出。
2. `this.$refs.scrollContainer` 所引用的元素还没有被渲染,可以在 `mounted()` 生命周期中设置 `setTimeout()` 延迟执行设置 `scrollTop` 的代码,例如:
```
mounted() {
setTimeout(() => {
this.$refs.scrollContainer.scrollTop = 200
}, 0)
}
```
3. `this.$refs.scrollContainer` 的样式可能会影响 `scrollTop` 的设置,可以使用浏览器的开发者工具检查该元素的样式和 `scrollTop` 的设置是否正确。
希望以上提示能够帮到您解决问题,如果还有疑问,请继续提问。
