vue中v-show和v-if在显示和隐藏元素上的区别

v-show将元素隐藏是在dom节点上加style=’display:none’
v-if是直接将元素完全去掉

拿v-show示例,(v-if 也是一样,把下面的代码中v-show替换成v-if即可运行)

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <meta charset="utf-8">
    <script src="http://unpkg.com/vue/dist/vue.js"></script>

    <script type="text/javascript">
        window.onload = function(){
            var vm = new Vue({
                el:'#box',
                data:{
                    isShow:false,
                },
                methods:{
                    toggle:function(){
                        this.isShow = !this.isShow;
                    }
                }
            });
        }
    </script>
</head>
<body>
    <div id="box">
        <input type="button" value="toggle" v-on:click="toggle()"> <br />
        <div v-show="isShow" style="width: 100px;height: 100px;background: red"></div>
    </div>
</body>
</html>
