我想在光标从一个文本框移动到下一个文本框时立即调用一个函数。单击选项卡时或输入预期条目并移至下一个条目后，应调用该函数。
Use the v-on指示 https://v2.vuejs.org/v2/guide/events.html#Method-Event-Handlers添加事件监听器blur https://developer.mozilla.org/en-US/docs/Web/Events/blur or focusout https://developer.mozilla.org/en-US/docs/Web/API/Element/focusout_event on the <input>:
v-on:EVENT_NAME="METHOD"
Example:
<input v-on:blur="handleBlur">
或者更短的语法：
@EVENT_NAME="METHOD"
Example:
<input @blur="handleBlur">
new Vue({
el: '#app',
methods: {
handleBlur(e) {
console.log('blur', e.target.placeholder)
},
handleFocusout(e) {
console.log('focusout', e.target.placeholder)
}
}
})
<script src="https://unpkg.com/[email protected] /cdn-cgi/l/email-protection/dist/vue.min.js"></script>
<div id="app">
<fieldset>
<legend>blur</legend>
<input @blur="handleBlur" placeholder="first name">
<input @blur="handleBlur" placeholder="last name">
</fieldset>
<fieldset>
<legend>focusout</legend>
<input @focusout="handleFocusout" placeholder="email">
<input @focusout="handleFocusout" placeholder="phone">
</fieldset>
</div>
