第一步在需要引入jquery库,这一步不能少，可以使用本地js或者下面的cdn或者其他的cdn（一般都放在主题中的footer.php）
第二步把下面的html代码和js代码放到主题相关文件中（一般都放在主题中的footer.php）
**html表单**
**js代码**
第三步在把下面的代码添加到相关文件中,(一般index.php)，找到这段代码“next()):
?>//此次省略无数代码”代码里面
第四步把下面的代码添加到相关文件中（一般function.php）
// 主题初始化
function themeInit($self)
{
$route = $self->request->getPathInfo();
/* 主题开放API 路由规则 */
