从ContentTools中的自定义媒体管理器插入图像

我可以提供的最好的示例是用于KCFinder的实现，KCFinder是另一个用PHP编写的媒体管理器，我相信它（至少在我帮助过的实现中）使用新窗口而不是iframe，但我相信原理是相同的。

正如您已经指出的，最简单的解决方案是编写自己的映像工具以替换默认工具，这样，通过CT映像对话框和ImageUploader类讨论的上载和/或返回映像的责任将切换到自定义媒体管理器。本教程。

以下是我们用于KCFinder的工具代码的修改版本：

当我说我们，我指的是我和沃特·范·Marrum谁提出，并帮助创建github上KCFinder例子在这里）

// So this little bundle of variables is required because I'm using CoffeeScript
// constructs and this code will potentially not have access to these.
var __slice = [].slice,
__indexOf = [].indexOf || function(item) { for (var i = 0, l = this.length; i < l; i++) { if (i in this && this[i] === item) return i; } return -1; },
__hasProp = {}.hasOwnProperty,
__extends = function(child, parent) { for (var key in parent) { if (__hasProp.call(parent, key)) child[key] = parent[key]; } function ctor() { this.constructor = child; } ctor.prototype = parent.prototype; child.prototype = new ctor(); child.__super__ = parent.prototype; return child; },
__bind = function(fn, me){ return function(){ return fn.apply(me, arguments); }; };

// Define out custom image tool
var CustomImageTool = (function(_super) {
    __extends(CustomImageTool, _super);

    function CustomImageTool() {
      return CustomImageTool.__super__.constructor.apply(this, arguments);
    }

    // Register the tool with ContentTools (in this case we overwrite the 
    // default image tool).
    ContentTools.ToolShelf.stow(CustomImageTool, 'image');

    // Set the label and icon we'll use 
    CustomImageTool.label = 'Image';
    CustomImageTool.icon = 'image';

    CustomImageTool.canApply = function(element, selection) {    
        // So long as there's an image defined we can alwasy insert an image
        return true;
    };

    CustomImageTool.apply = function(element, selection, callback) {

        // First define a function that we can send the custom media manager
        // when an image is ready to insert.
        function _insertImage(url, width, height) {
            // Once the user has selected an image insert it

            // Create the image element
            var image = new ContentEdit.Image({src: url});

            // Insert the image
            var insertAt = CustomImageTool._insertAt(element);
            insertAt[0].parent().attach(image, insertAt[1]);

            // Set the image as having focus
            image.focus();

            // Call the given tool callback
            return callback(true);

            window.KCFinder = null;
        }

        // Make the new function accessible to your iframe
        window.parent.CustomMediaManager = {_inserImage: _insertImage};

        // Hand off to your custom media manager
        //
        // This bit you'll need to figure out for yourself or provide more
        // details about how your media manager works, for example in 
        // KCFinder here we open a new window and point it at the KCFinder
        // browse.php script. In your case you may be looking to insert an
        // iframe element and/or set the src for that iframe. 
        //
        // When the user uploads/selects an image in your media manager you
        // are ready to call the `_insertImage` function defined above. The
        // function is accessed against the iframe parent using:
        //
        //     window.parent.CustomMediaManager._insertImage(url, width, height);
        //

    };

    return CustomImageTool;

})(ContentTools.Tool);

我希望能提供足够的帮助您集成您的媒体管理器，但如果不能，那么您可以提供有关媒体管理器工作方式的更多详细信息（也许我可以查看一个示例），我将很乐意尝试并提供一个更完整的解决方案。
