Question

我正在设立一个管理员,用户可以预订其喜欢的网页URLs,然后在文件夹中管理。

During app load, I render a view which shows the list of folders user has created. this view is invisible on page load.
then user navigates to his home page to see a list of urls
from there, user can arrange the urls in folders
user clicks the Move to folder icon in URL view
I want to display the folderSelectorView absolute positioned below the Move to Folder icon. How can I do that?
Also if the url has already been moved to a folder, I want a checked sign to appear in the folderSelectorView in the folder where the url has been moved to.

我应怎样做呢?

这里是我如何把文件夹在上面。

var folderColl = new FolderColl();
new FolderSelectorView({collection: folderColl});

The Code for URL view.

URLView = Backbone.View.extend({
    tagName:  li ,
    template: _.template($( #URLTempalte ).html()),
    events: {
         click .FolderChange :  showFolderSelector 
    },

    initialize: function() {
        _.bindAll(this,  render );
    },

    render: function() {
        return $(this.el).html(this.template(this.model.toJSON()));
    },

    showFolderSelector: function() {
       // How should I display the view here
       // view should display below the "Move to folder" icon
       // Doing something like `new FolderSelectorView` is not what I m after
       // since that will just re-render the view for every URL displayed
    }
});

你可以轻而易举地对现有的超文本部分寄以主意。你们需要做的是通过<代码>el,以供查阅。 <el>可以是你想要的东西,包括通过j Query 挑选人发现的现有html要素。

var myEl = $("#someElementOnThePage");
var myView = new MyView({
  el: myEl
});

This will attach your view to the #someElementOnThePage element, and you can then use it as if you had rendered it yourself.
