When we need to perform gender conversion in a Vue project, we can encapsulate a global gender conversion function so that it can be used anywhere in the project. This article describes how to use TypeScript and Vue to achieve this functionality.
We can srccreate a utilsfolder under the directory of the Vue project, and create a gender.tsfile under this folder. code show as below:
enum Gender {
MALE = '男',
FEMALE = '女',
UNKNOWN = '未知'
}
export function genderFormatter(value: string | number): string {
switch (value) {
case 1:
case '1':
return Gender.MALE
case 2:
case '2':
return Gender.FEMALE
default:
return Gender.UNKNOWN
}
}
In the above code, we define an Genderenumeration to store the Chinese representation of gender. We also define a genderFormatterfunction for converting a numeric or string type gender to Chinese representation.
When using this function, we only need to import this function in the Vue component and call it. For example:
<template>
<div>
{
{
gender | genderFormatter }}
</div>
</template>
<script lang="ts">
import {
Component, Vue } from 'vue-property-decorator'
import {
genderFormatter } from '@/utils/gender'
@Component
export default class ExampleComponent extends Vue {
private gender = 1
private created() {
console.log(genderFormatter(this.gender))
}
}
</script>
In the above code, we use Vue's filter function to call genderFormatterthe function. createdIn the lifecycle hook of the component , we can also directly call this function to perform gender conversion.
Through the above methods, we can easily perform gender conversion operations in the Vue project, which improves the reusability and maintainability of the code.
