是否有任何类(如goog.ui.dialog)让我显示一个对话框,其内容可以通过 ajax 从其他文件中获取?

  • goog.ui.Dialog是否适合此目标?
  • 我应该使用good.net.XHRgoog.ui.Popup等其他基础类来实现吗?

您可以扩展goog.ui.dialog并获取内容。

一个可以帮助你的简单例子:

my.ui.Dialog = function(opt_iframe) {
  goog.ui.Dialog.call(this, null, opt_iframe);

  this.xhr_  = new goog.net.XhrIo();
  this.xhr_.addEventListener(goog.net.EventType.COMPLETE,
                             this.onComplete_, false, this);

  goog.events.listen(this, goog.ui.Dialog.EventType.SELECT,
                     this.dispatch_, false, this);
};
my.ui.Dialog.prototype.buildWindow_ = function (responseJson) {
  this.setTitle(responseJson.title);
  this.setContent(responseJson.content);
  this.setButtonSet(eval(responseJson.buttons));
};
my.ui.Dialog.EventType = {
  'COMPLETE': 'complete'
};
my.ui.Dialog.prototype.onComplete_ = function (event) {
var json = this.xhr_.getResponseJson ()
    this.buildWindow_ (json);
    this.reposition ();
};
my.ui.Dialog.prototype.send = function (uri, method, post_data) {
  this.xhr_.send(uri, method, post_data, null, {'X-DIALOG':'AJAX'});
};
goog.inherits (my.ui.Dialog, goog.ui.Dialog);

在json中使用响应来构建像这样的ui.Dialog:

{"buttons": "goog.ui.Dialog.Buttons.OK_CANCEL", 
 "content": "<html><body><h1>Hello</h1></body></html>", 
 "title": "Hello World"}

此示例无法直接使用:/
