示例:

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8" />
        <title>收集表单数据</title>
        <script type="text/javascript" src="../js/vue.js"></script>
    </head>
    <body>
        <!-- 
            收集表单数据:
                    若:<input type="text"/>,则v-model收集的是value值,用户输入的就是value值。
                    若:<input type="radio"/>,则v-model收集的是value值,且要给标签配置value值。
                    若:<input type="checkbox"/>
                            1.没有配置input的value属性,那么收集的就是checked(勾选 or 未勾选,是布尔值)
                            2.配置input的value属性:
                                    (1)v-model的初始值是非数组,那么收集的就是checked(勾选 or 未勾选,是布尔值)
                                    (2)v-model的初始值是数组,那么收集的的就是value组成的数组
                    备注:v-model的三个修饰符:
                                    lazy:失去焦点再收集数据
                                    number:输入字符串转为有效的数字
                                    trim:输入首尾空格过滤
