#使用实例

#初始化数据data
var initvue = {

registinfo_chakan_money : '100',
registinfo_rescue_money : '1000',
address : '广东省汕头市潮南区',
registinfo_chakan_data : '2017-5-7',
registinfo_say : '这个只是测试用的',
remark : '龙军用来测试的',
prplregist_name : '林总',
prplregist_user : '林老板',
prplregist_phone : '10010',

prplregist_rescue_money : '一个亿',
registinfo_radio : "runoob",

};
//初始化vue表单
vueformsub.initvue(initvue,"container-fluid");
//返回按钮单击
function getinputval(){
//调用自动表单封装
var resultval = new vueformsub("container-fluid");
console.log(resultval);
}
#注意：input表单中的name属性必须指定，最好和input表单中的v-model的值一样
