jQuery中的.css方法中的+ =运算符(+= operator within .css method in jQuery)

 有什么办法可以在css运算符中实现+ =运算符（假设示例中的ui.value具有数值）  
 像这样的东西（这不起作用）：  
$("#resume_holder").contents().find('body').children().css('font-size', +=ui.value);

Is there any way to achieve a += operator within the css operator (assuming ui.value in the example has a numerical value) 
Something like this(which doesn't work): 
$("#resume_holder").contents().find('body').children().css('font-size', +=ui.value);

 电影示例是散景服务器应用程序。 它只能通过运行Bokeh服务器来使用，即通过执行  
bokeh serve --show movies
 
 在命令行上。 没有要创建的输出文件。 要与Bokeh服务器应用程序交互，必须运行它 。  
 Bokeh应用程序中代码的工作是构建一个Bokeh文档（即放入图表和小部件等），这就是它使用curdoc().add_root(...)所做的事情。 脚本中的代码是在布局中构建绘图和小部件，并将其添加到新文档中。 每次浏览器连接到Bokeh服务器时，Bokeh服务器都会运行应用程序代码，为该会话创建一个新的新文档。  
 相反， output_file函数用于生成不依赖于Bokeh服务器的 独立 HTML / JS。 （在独立文档中仍然可以进行大量的交互，像CustomJS回调一样，你通常无法运行真正的Python代码 。）  
 （也可以在常规python脚本中“嵌入”Bokeh作为库，但这是一种更高级的用法。例如，请参阅用户指南部分将Bokeh服务器嵌入库中以获取更多信息。） 

The Movies example is a bokeh server application. It can only be used by running it with a Bokeh server, i.e. by executing 
bokeh serve --show movies
 
on the command line. There is no output file to create. To interact with a Bokeh server application, it has to be run. 
The job of the code inside a Bokeh application is to build up a Bokeh document (i.e. put in plots and widgets, etc) so that is what it is doing with curdoc().add_root(...). The code in the script is building up plots and widgets in a layout, and adding that to a new document. Every time a browser connects to a Bokeh server, the Bokeh server runs the application code to create a new fresh Document for that session.  
The output_file function, by contrast, is for generating standalone HTML/JS that does not rely on the Bokeh server. (It's still possible to have lots of interactions in standalone documents, with things like CustomJS callbacks, you generally just can't run real Python code.) 
(It is also possible to "embed" a Bokeh serve as a library in a regular python script, but that's a more advanced usage. See, e.g. the user's guide section Embedding Bokeh Server as a Library for more information.)
