[已解决] webpack 入口文件里 require 依赖文件后，怎么调用里面的方法？

killpigman — Fri, 25 Mar 2016 00:44:17 +0800

// main1.js
function add() {
           document.write('<h2>Hello Webpack</h2>');
}

// main2.js
require("main1");
//在这里require之后，直接调用add()方法，会报add is not defined

module.exports = {
  entry: {
    bundle: './main2.js',
  },
  output: {
    filename: '[name].js'
  }
};

如何在 main2 里调用 main1 里的方法？

页面不跳转，在 js 里输出返回值，是我要跳转的 html。

def create
    @imprint = Imprint.new(imprint_params)
    @imprint.save
    redirect_to @imprint
end

def show
    @imprint = Imprint.find(params[:id])
end

[已解决] 如何在表单 submit 的同时，将点击时的定位坐标一起传过去？

killpigman — Tue, 26 Jan 2016 11:54:43 +0800

想在 submit 的同时，将点击时的定位坐标一起传过去。定位坐标是在 js 里面生成的。

<%= form_for :notes, url: notes_path do |f| %>
    <%= f.hidden_field :lng %>
    <%= f.hidden_field :lat %>
    <%= f.hidden_field :accuracy %>
    <p>
        <%= f.label :text %><br>
        <%= f.text_area :text %>
    </p>

    <p>
        <%= f.submit class:"btn btn-primary" %>
    </p>
<% end %>
