Pass variables from bokeh to JS via CustomJS

In the bokeh example http://docs.bokeh.org/en/latest/docs/user_guide/interaction/callbacks.html#customjs-for-hover the dictonary "links" is passed to the JS by adding it at the end of the code block with: ....

""" % links

Is it possible to pass over two variables and what would the syntax look like? I tried different versions like

""" % links,myvar
""" % ('links','myvar')
""" % links, % myvar

but they all create errors or do not work. I also found this Bokeh: pass vars to CustomJS for Widgets but perhaps there is an update? Thx

Solution

  • I'd suggest looking into general python string formatting (there isn't anything Bokeh-specific within that example).

    But some options would be

    JS_CODE = """
var variable_1 = %s
var variable_2 = %s
""" % (var1, var2)

    or 

    JS_CODE = """
var variable_1 = {0}
var variable_2 = {1}
""".format(var1, var2)

    or to set as a list

    JS_CODE = """
var list_variable = %s
""".format(str(list_var))
