我正在尝试使用vee-validate创建一个简单的表单验证页面。不过似乎有些问题，我不确定我到底在做什么错。
我收到vue控制台错误errors not defined
有什么建议么？
<!DOCTYPE html>
<html>
<head><head>
<body>
<div id="app">
<h1>asdfasd</h1>
<form action='#' method='POST'>
<input v-validate="'required|email'" :class="{'input': true, 'is-danger': errors.has('email_primary') }" name="email_primary" type="text" placeholder="email_primary">
<span v-show="errors.has('email_primary')" class="help is-danger">{{ errors.first('email_primary') }}</span>
<button class="button is-link" name='submitform' value='go'>Submit</button>
</form>
</div>
<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/[email protected]/dist/vue.min.js"></script>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/vee-validate/3.0.5/vee-validate.full.min.js"></script>
<script>
Vue.use(VeeValidate);
new Vue({
el: "#app",
template: '#app',
data() {
return {
email_primary: null
};
}
});
</script>
</body>
</html>
最佳答案
您似乎使用了veevalidate 3而不是veeValidate2。我在回答中将veevalidate更新为版本2，并添加了v-model="email_primary"
由于您已经有了模板，因此我已删除了template: '#app',。请看下面
<!DOCTYPE html>
<html>
<head>
<head>
<body>
<div id="app">
<h1>asdfasd</h1>
<form action='#' method='POST'>
<input v-model="email_primary" v-validate="'required|email'"
:class="{'input': true, 'is-danger': errors.has('email_primary') }"
name="email_primary" type="text" placeholder="email_primary">
<span v-show="errors.has('email_primary')" class="help is-danger">{{ errors.first('email_primary') }}</span>
<button class="button is-link" name='submitform' value='go'>Submit</button>
</form>
</div>
<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/[email protected]/dist/vue.min.js"></script>
<script type="text/javascript"
src="https://cdnjs.cloudflare.com/ajax/libs/vee-validate/2.2.15/vee-validate.min.js"></script>
<script>
Vue.use(VeeValidate);
new Vue({
el: "#app",
data() {
return {
email_primary: null
};
}
});
</script>
</body>
</html>这是working fiddle。希望我的回答会有所帮助。
