带网格的输入框组件,可以用于输入支付密码、短信验证码等,通常与数字键盘组件配合使用
import Vue from 'vue';
import { PasswordInput, NumberKeyboard } from 'vant';
Vue.use(PasswordInput);
Vue.use(NumberKeyboard);
<!-- 密码输入框 -->
<van-password-input
:value="value"
info="密码为 6 位数字"
:focused="showKeyboard"
@focus="showKeyboard = true"
/>
<!-- 数字键盘 -->
<van-number-keyboard
:show="showKeyboard"
@input="onInput"
@delete="onDelete"
@blur="showKeyboard = false"
/>
export default {
data() {
return {
value: '123',
showKeyboard: true
};
},
methods: {
onInput(key) {
this.value = (this.value + key).slice(0, 6);
},
onDelete() {
this.value = this.value.slice(0, this.value.length - 1);
}
}
}
<van-password-input
:value="value"
:length="4"
:gutter="15"
:focused="showKeyboard"
@focus="showKeyboard = true"
/>
<van-password-input
:value="value"
:mask="false"
:focused="showKeyboard"
@focus="showKeyboard = true"
/>
通过error-info属性可以设置错误提示信息,例如当输入六位时提示密码错误
<!-- 密码输入框 -->
<van-password-input
:value="value"
:error-info="errorInfo"
:focused="showKeyboard"
@focus="showKeyboard = true"
/>
<!-- 数字键盘 -->
<van-number-keyboard
:show="showKeyboard"
@input="onInput"
@delete="onDelete"
@blur="showKeyboard = false"
/>
export default {
data() {
return {
value: '123',
showKeyboard: true,
errorInfo: ''
};
},
methods: {
onInput(key) {
this.value = (this.value + key).slice(0, 6);
if (this.value.length === 6) {
this.errorInfo = '密码错误';
} else {
this.errorInfo = '';
}
},
onDelete() {
this.value = this.value.slice(0, this.value.length - 1);
}
}
}
