vue developer I used @ click.once to trigger an event to prevent repeated call-up of the payment interface, but if the user chooses to cancel or click * in WeChat Pay, this button cannot be adjusted again. What to do
@ click.once= "toPay ()"
toPay () {
//}
the expected result is that it is called only once, and if the user clicks to cancel the payment, this button returns to the state that can only be clicked once
self-control. Add a tag default value of true . toPay determines this tag, true executes it, and once executes it, it changes to false .
cancel or time out, you can change to true
you can refer to
data to define a field that can be submitted, such as canPay . True means payment can be made, and vice versa
<button @click="toPay" :disabled="!canPay"></button>
<button @click="canclePay"></button>
data(){
return {
canPay: true
}
},
methods: {
toPay(){
if(this.canPay){
this.canPay = false
//
axios.post('/api/xxx',{})
.then(res => {
//
})
.catch(err => {
//canPaytrue
this.canPay = true
})
}else {
console.log('')
}
},
canclePay(){
//
//canPaytrue
this.canPay = true
}
