Any help with minor but very frustrating issues would be greatly appreciated. I'm developing a Vue project using element plus library. User input: '123456789' I need to dial:' 998-(12) 345-67-89
Element plus has formatter but I need to make it using regular expressions. Unfortunately I'm having trouble getting it to work. https://element-plus.org/en-US/component/input.html#formatter
I have only checked the number now and cannot learn more
<script setup> import { ref, unref } from 'vue' import { ElInput } from 'element-plus' const phoneNumber = ref('') </script> <template> <el-input v-model="phoneNumber" :formatter="(value) => value.replace(/D/g, '')" /> </template>
You can use the following regular expressions:
The first
.replace(/^\ 998|\D/g, '')
Removes the998
at the beginning of the string (replaced by a successful follow-up) and any non Numeric characters, andreplace(/^(\d{1,2})(\d{1,3})?(\d{1,2})?(\ d{1,2})? .*/, (m, g1, g2, g3, g4) => ` 998-(${g1})` (g2 ? `-${g2}` : '' ) (g3 ? `-${g3} ` : '') (g4 ? `-${g4}` : ''))
Start as you type only if necessary by adding-
重新格式化数字>.
