js 前端合成excel（ThinkPHP5+html+js：比纯后端合成来的快，而且超级简单。）
思路：
因为岗位是PHP，框架用的TP5，所以想用PHPExcel插件生成excel，无赖折腾了半个小时，不想折腾了。所以用js+html做算了（最终花费20分钟，又快又好做）。
1. 后端返回查询的数据集：
/*
* 利用js合成excel接口
* */
public function out_excel(){
$login_name = input("login_name");
$pwd = input("pwd"); // 前端md5，后端再base64
$check = $this->user_check($login_name, $pwd); // 安全校验
if($check){
$res = Db::name("wx_account")->field("id, wx_name, wx_login, wx_property, close_days, open_date, close_reason, fans_num, manager, add_fans, add_wx_time, flow_income, add_fans_time, add_fans_way, ad_owner, ad_owner_spend, ad_income, migration, migration_add_fans, login_email, fans_property, original_id, migration_remark, body_company, body_company_num, qr, today_income, today_first_news_amount")->select();
$back = [
"state"=>1,
"msg"=>"查询完成",
"content"=>$res,
];
}else{
$back = [
"state"=>0,
"msg"=>"安全校验失败",
"content"=>null,
];
}
return json_encode($back, JSON_UNESCAPED_UNICODE);
}2. 然后前端把数据渲染成<table id=""><tr><th></th></tr><tr><td scope="row"></td><td></td></tr><tr><td scope="row"></td><td></td></tr><table>合适，然后利用js整体输出excel即可。
