Let's talk about the situation when vue formatting is not executed

In Vue development, we often use Vue's filter function to format data through filters to meet business needs. However, during the development process, sometimes you encounter situations where the filter cannot perform properly. This article will introduce some solutions.

1. Check whether the filter name is correct

To use filters in Vue, you need to first define the filter function, then use Vue.filter() to register the filter, and finally in the template Use filters. If the filter is not named correctly, it will not execute properly. Therefore, we need to double check that the filter is named correctly.

2. Check whether the filter is registered successfully

After the filter is defined, you need to use Vue.filter() to register it. If registration is not successful, the filter cannot be used in the template. We can view the Vue instance object in the browser console to see if the filter is successfully registered.

3. Check whether the data is correctly bound

The filter needs to be bound to the data. If the data is not bound correctly, the filter cannot execute normally. We can print out the data in the template to see if the binding is successful.

4. Check whether an invalid filter is used

Sometimes when we use a filter, we may write the wrong name of the filter, or use a filter that does not exist, resulting in filtering The server cannot execute normally. If this happens, we need to check if these errors exist in the code.

5. Check whether the Vue version is too low

In the Vue 2.x version, the way filters and instructions are used has changed. If your Vue version is lower, it may cause the filter to fail to execute. The solution to this problem is to upgrade the Vue version so that it meets the current requirements.

In development, it is not uncommon to encounter the problem that the filter cannot be executed normally, but as long as we patiently check the code, we can find the problem and solve it in time. Hope this article is helpful to you!
