1vue模板语法

<body>
    <div id="app1">
        <div>{{msg}}</div>
    </div>
    <script type="text/javascript" src="../vue.js"></script>
    <script type="text/javascript">
        var vm = new Vue({
            el:'#app1',
            data: {
                msg:'Hello vue'
            }
        })
    </script>
</body>

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <style type="text/css">
        [v-clock] {
        display:none
    }
    </style>
</head>
<body>
    <div id="app1">
        <div v-colck>{{msg}}</div>
    </div>
    <script type="text/javascript" src="../vue.js"></script>
    <script type="text/javascript">
        var vm = new Vue({
            el:'#app1',
            data: {
                msg:'Hello vue'
            }
        })
    </script>
</body>
</html>

上面是v-clock指令，解决插值表达式闪动问题

下面是v-text

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <style type="text/css">
        [v-clock] {
        display:none
    }
    </style>
</head>
<body>
    <div id="app1">
        <div v-text="msg"></div>
    </div>
    <script type="text/javascript" src="../vue.js"></script>
    <script type="text/javascript">
        var vm = new Vue({
            el:'#app1',
            data: {
                msg:'Hello vue'
            }
        })
    </script>
</body>
</html>

v-html解析html的标签

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <style type="text/css">
        [v-clock] {
        display:none
    }
    </style>
</head>
<body>
    <div id="app1">
        <div v-html="msg1"></div>
    </div>
    <script type="text/javascript" src="../vue.js"></script>
    <script type="text/javascript">
        var vm = new Vue({
            el:'#app1',
            data: {
                msg1:'<h1>html</h1>'
            }
        })
    </script>
</body>
</html>

v-pre跳过插值表达式的编译，显示原始内容

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>
    <style type="text/css">
        [v-clock] {
        display:none
    }
    </style>
</head>
<body>
    <div id="app1">
        <div v-pre=>{{msg1}}</div>
    </div>
    <script type="text/javascript" src="../vue.js"></script>
    <script type="text/javascript">
        var vm = new Vue({
            el:'#app1',
            data: {
                msg1:'<h1>html</h1>'
            }
        })
    </script>
</body>
</html>

v-once可以提高性能

v-model 用在input标签中，数据双向绑定

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Document</title>

</head>
<body>
    <div id="app1">
        <div v-text='msg1'></div>
        <div>
            <input type="text" v-model='msg1'>
        </div>
    </div>
    <script type="text/javascript" src="../vue.js"></script>
    <script type="text/javascript">
        var vm = new Vue({
            el:'#app1',
            data: {
                msg1:'Hello world'
            }
        })
    </script>
</body>
</html>
