What are the precautions for using vux-ui custom form validation in Vue?
This time I will bring you Vue customization using vux-uiForm verificationWhat are the things to noteThe following is a practical case, let’s take a look.
When I first started using the framework vue with vux, I found that using this UI library was a bit incompetent. Let’s talk about the two demand problems I encountered during the form verification process and how to solve them.
1. Using the x-input component, we can see that the official only provides three types of is-typeverifier, namely: email, china-name, china-mobile, others are required How to write a custom validator?
Solution: Customize the is-type validator (you can use regular verification in valid after testing)
<x-input type="number" v-model="code" placeholder="请输入验证码" :is-type="codeValue" />
export default {
data() {
return{
code: '',
codeValue: function(value){
return {
valid: value.length === 4,
msg: "验证码有误!"
}
}
}
}
}2. Only after the form content is filled in correctly can the button to submit the form be triggered ( As shown in the picture)
Solution: Use the @on-change event of the x-input component and the ref attribute
<x-input type="number" v-model="code" placeholder="请输入验证码" :is-type="codeValue" ref="refcode" @on-change="keyDown" />
<x-button action-type="submit" :disabled="disabled">完成</x-button>
export default {
data() {
return{
code: '',
disabled: true,
codeValue: function(value){
return {
valid: value.length === 4,
msg: "验证码有误!"
}
}
}
},
methods: {
keyDown(){
if(this.$refs.refcode.valid == true && this.code != ''){
this.disabled = false;
}else{
this.disabled = true;
}
}
}
