怎么检查this.$set is not a function
时间: 2023-10-01 07:06:24 浏览: 38
检查以下几点:
1. 确认你正在使用Vue.js,因为this.$set是Vue.js提供的一个API,如果你没有使用Vue.js,那么它将不可用。
2. 确认你的Vue.js版本是否是2.1.0或更高版本,因为在这个版本中,this.$set被添加到了Vue.js中。
3. 确认你正在尝试在正确的作用域中使用this.$set。在Vue.js中,this.$set只能在Vue实例的方法中使用,如created,mounted等。
如果你仍然无法解决问题,请提供更多的代码和错误信息,以便更好地理解问题的背景。

_this.$set is not a function
_this.$set is a function provided by the Vue.js framework. It is used to update the value of a reactive property in a Vue instance. The error message "_this.$set is not a function" usually occurs when you try to use _this.$set but it is not defined.
There are several reasons why this error might occur. One common cause is that the Vue instance has not been properly initialized or the Vue.js library has not been loaded. Another possible cause is that there is a syntax error or typo in your code that is preventing the Vue.js framework from recognizing _this.$set as a valid function.
To fix this error, you can try checking that the Vue.js library has been properly loaded, and that your Vue instance has been initialized correctly. You can also check for any syntax errors or typos in your code that might be causing the issue.
this.$set is not function
this.$set is a Vue.js method used to update the value of a property in Vue's reactive data system. It allows you to add or modify a property in an object so that Vue can detect the change and update the UI accordingly.
If you are getting an error message that says "this.$set is not a function", it is likely because you are trying to use it in a context where it is not available.
There are a few possible reasons for this error, such as:
1. You may be trying to use this.$set outside of a Vue component or instance.
2. You may be using an outdated version of Vue that does not include the $set method.
3. You may have a typo in your code, such as writing this.$sets instead of this.$set.
To fix this issue, make sure that you are using this.$set within a Vue component or instance, and that you have included the latest version of Vue. Also, double-check your code for any typos or syntax errors.
