#VueFormSub.js（实现双向绑定主要代码）
//实现取值
var VueFormSub = function(formid){

#初始化Vue表单数据(可以只传入initDate数据源，formid需要绑定的dom)

#对需要绑定的对象进行解析成Vue支持的格式

#使用实例
<script>
#初始化数据data
var initVue = {
RegistInfo_name : 'legend',
RegistInfo_user : '龙军',
RegistInfo_phone : '1008611',
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_chakan_money : '一万块',
Prplregist_rescue_money : '一个亿',
RegistInfo_radio : "Runoob",
RegistInfo_selected : "google",
RegistInfo_helongjun : "helongjun",
testOne:""
};
//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
<script>
最终效果：
