Mercury 编辑器 'saved' 事件未触发

Mercury Editor 'saved' event not firing

我的 Mercury Gem - 版本 0.9.0

gem 'mercury-rails', git: 'https://github.com/jejacks0n/mercury.git'

我正在使用 Rails4

最初遵循 RailsCast,我在 Mercury.js 中有以下内容:

$(window).bind('mercury:ready', function() {
  var link = $('#mercury_iframe').contents().find('#edit_link');//extract the saveURL for mercury that was encoded in the HTML data tag
  Mercury.saveUrl =link.data('save-url');
  console.log("Mercury save URL: "+Mercury.saveUrl);
  link.hide();//hide edit url
});

$(window).bind('mercury:saved', function() {
  console.log("mercury saved event set");
  window.location.href = window.location.href.replace(/\/editor\//i, '/');
});

但是,RailsCast 评论说现在应该覆盖 onload 函数:

window.Mercury = {
  //...

  //CUSTOM CODE
  onload:function(){
    Mercury.on('saved',function(){
        console.log("SAVE EVENT FIRED");
        window.location.href = window.location.href.replace(/\/editor\//i, '/');            
    });
    Mercury.on('ready',function(){
        var link = $('#mercury_iframe').contents().find('#edit_link');//extract the saveURL that was encoded in the HTML data tag
        Mercury.saveUrl =link.data('save-url');
        console.log("Mercury save URL: "+Mercury.saveUrl);
        link.hide();//hide edit url
    });
  }
};

但是,保存的事件永远不会触发,也永远不会发生重定向。关于做事的新方法和改进方法有什么想法吗?谢谢!

编辑:澄清一下,“Mercury.on('ready'...)”事件确实成功触发。

编辑:好的,所以我发现 'saved' 事件适用于一条路线,但不适用于另一条路线。

#Works on this route! 
def mercury_update_courses
    courses_infos = params[:content]
    courses_infos.each{|course_info|
        label = course_info[0]
        new_val = course_info[1][:value]

        id = label.delete("^0-9")#find the database id by removing everything that's not a number from the HTML element's CSS id
        course = EditablePage.where("id == ?",id).last

        if label.index("title") != nil
            course.title = new_val
        elsif label.index("body") != nil
            course.body = new_val
        end

        course.save!
    }
    render text: ""
end

#does not work on this route!
def mercury_update_index
    homepage = EditablePage.find(params[:id])
    homepage.body = params[:content][:homepage_content][:value]
    homepage.save!
    render text: ""
end

发现问题了!毕竟保存事件实际上是有效的。

console.log("SAVE EVENT FIRED");

没有出现,因为它被放置在重定向之前,这会擦除 JS 控制台。在我发现它在一个页面而不是另一个页面上工作后,我试图找出这些页面的不同之处,发现问题出在 URL.

#working
  http://localhost:3000/editor/courses
#not working
  http://localhost:3000/editor

因此问题出在我从我遵循的教程中复制粘贴的神秘正则表达式

window.location.href = window.location.href.replace(/\/editor\//i, '/');

是罪魁祸首。非工作编辑器在站点的 root/homepage 上,因此没有在 url 的“/editor/”部分中包含第二个“/”。我通过制作更通用(更易于理解)的替换行

来解决此问题
window.location.href = window.location.href.replace("/editor", '');

最终代码:

window.Mercury = {
  //...

  //CUSTOM CODE
  onload:function(){
    Mercury.on('saved',function(){
        window.location.href = window.location.href.replace("/editor", '');
        console.log("Mercury info saved!"); 
    });
    Mercury.on('ready',function(){
        var link = $('#mercury_iframe').contents().find('#edit_link');//extract the saveURL that was encoded in the HTML data tag
        Mercury.saveUrl =link.data('save-url');
        console.log("Mercury save URL: "+Mercury.saveUrl);
        link.hide();//hide edit url when mercury is open
    });
  }
};
