If you'd like to take a stab at it yourself, we are happy to help answer any questions, etc. I have marked it for the 0.12.6 milestone. However, some recent work for a general events callback mechanism that is landing in 0.12.5 should have laid most of the necessary groundwork for this feature to be implemented fairly easily. Thank you! Bokeh is a wonderful tool and I am grateful for the hard work contributors have put in, and for the excellent community support. I’m also not much of a front-end programmer, so apologies for any incorrect terminology. I realize I’m being a little loose with my terms – I’m not too picky if I can run my code after, during, or just before elements appear on the page. Forgive my ignorance, but it seems like there could be something like: curdoc().add_callback("render", function) – does it exist? If not, could it be created without too much trouble? I’d be happy to do the leg work for a PR, but I suspect it would have to be done in coffeescript, and I don’t know coffeescript (I barely know javascript). I’m not familiar with the internals of Bokeh’s rendering process, but it seems like the solution to my problem is to hook into that somehow. I’m not sure if the timing of this would work, and it also seems very messy. So I could have a data source with an associated javascript onchange callback to remove the animation, and have the server put some dummy data in the data source. One possibility would be to have a callback on the server side, but as far as I can tell, the only way to propagate info to the browser would be through a model. line into the script returned by autoload_server() unfortunately has a similar effect – it runs when the script is loaded, not when it is finished running. Registering my snippet with document.onload makes it run way before the bokeh ui elements appear… so quickly that my animation doesn’t even show up. I’m looking for a hook that will run a javascript snippet when bokeh starts to populate the document with plots, widgets, etc, so that I can turn my animation off. I’m running my apps behind Flask, and right now I have a CSS animation baked into the template files. Use the string "15%" because the units are not px.I have a bokeh page that requires a few seconds to load, and I’d like to display a loading animation until the page is ready to go. Notice we're using a number, 10, because it's 10px. ( defn counting-button ( let state is accessible in the render function ( fn [ :een If you wrap that inner render function in a let, Then the renderįunction will be called each time the component needs to The outer function will beĬalled once to get the render function. Initialize something when the component is created, you useĪ Form-2 component. The next case is slightly more complicated. Theįunction corresponds to the React render() Want to define a function from inputs to DOM tree. Using React in a functional programming way. When we're using React from ClojureScript, we are typically Reagent components are functions Form-1 component Reagent lets you write React code that is concise and readable. Reagent has three main features that make it easy to use: using functions to create React components, using Hiccup to generate HTML, and storing state in Reagent Atoms. It gives you a way to easily create React components. Reagent is a ClojureScript wrapper around React.
