這篇文章主要為大家詳細介紹了vue v-model表單控制項綁定的相關資料，具有一定的參考價值，有興趣的小夥伴們可以參考一下
v-model 指令在表單控制項元素上建立雙向資料綁定，下面一一進行範例解釋。
1、v-model 雙向綁定文字
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title></title>
<script type="text/javascript" src="vue.js"></script>
</head>
<body>
<p id="app">
<input v-model="message" placeholder="edit me">
<p>Message is: {{ message }}</p>
</p>
</body>
<script>
var vm = new Vue({
el:"#app",
data: {
message: '绑定文本'
}
})
</script>
</html>輸出結果：
2、v- model 雙向綁定多行文本，與上面的例子相似。
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title></title>
<script type="text/javascript" src="vue.js"></script>
</head>
<body>
<p id="app">
<<span>Multiline message is:</span>
<p style="white-space: pre">{{ message }}</p>
<br>
<textarea v-model="message" placeholder="add multiple lines"></textarea>
</p>
</body>
<script>
var vm = new Vue({
el:"#app",
data: {
message: '绑定多行文本'
}
})
</script>
</html>輸出結果：
3、v-model 綁定複選框
<!DOCTYPE html>

<title></title>
<script type="text/javascript" src="vue.js"></script>
</head>
<body>
<p id="app">
<input type="checkbox" id="checkbox" v-model="checked">

</p>
</body>
<script>
var vm = new Vue({
