如何在组件销毁后重新打开组件时在created函数中根据value参数替换currentVal对应key的值，但又不影响currentVal的其他key的值
【以下回答由 GPT 生成】
首先，在Vue组件销毁后重新打开组件时，可以使用activated生命周期钩子函数来触发相应的逻辑。而为了保留currentVal对象的其他key的值不被替换，需要先对currentVal对象进行浅拷贝操作，然后再替换对应key的值。
具体的解决方案如下所示：
data(){
return {
currentVal: {
// ...
}
}
},
activated() {
// 在组件重新激活时进行替换操作
this.currentVal = { ...this.currentVal, [this.value]: this.getReplacementValue(this.value) };
},
methods: {
getReplacementValue(value) {
// 根据传入的value参数返回相应的替换值
if (value === 'module') {
return {
"value": "module",
"label": "新的内置模型",
// ...
};
}
if (value === 'form') {
return {
"value": "form",
"label": "新的网站表单",
// ...
};
}
if (value === 'custom') {
return {
"value": "custom",
"label": "新的自定义值",
// ...
};
}
// 如果传入的value参数没有匹配的情况下，可以返回一个默认值或者抛出异常
return null;
}
}
上述代码中，首先在activated生命周期钩子函数中通过浅拷贝操作将currentVal对象的其他key的值保留下来，然后根据传入的value参数调用getReplacementValue方法来获取相应的替换值，并将其赋值给currentVal对象相应的key中。
注意：以上代码假设value参数是一个组件内部的数据属性，可以通过this.value来获取。如果value参数是通过props传递的，则可以使用this.$props.value来获取。在使用时需要根据实际情况来修改。
