  "id": "f0157d7d-091a-4bf3-925a-d61af0f5bff4",
  "js_callbacks": {},
  "name": null,
  "tags": []
}

class CustomJS(**kwargs)[source]¶

Bases: bokeh.models.callbacks.Callback

Execute a JavaScript function.

args¶

property type: Dict ( String , Instance ( Model ) )

A mapping of names to Bokeh plot objects. These objects are made available to the callback code snippet as the values of named parameters to the callback.

code¶

property type: String

A snippet of JavaScript code to execute in the browser. The code is made into the body of a function, and all of of the named objects in args are available as parameters that the code can use. Additionally, a cb_obj parameter contains the object that triggered the callback and an optional cb_data parameter that contains any tool-specific data (i.e. mouse coordinates and hovered glyph indices for the HoverTool).

Note

Use CustomJS.from_coffeescript() for CoffeeScript source code.

classmethod from_coffeescript(code, args={})[source]¶

Create a CustomJS instance from CoffeeScript code.

classmethod from_py_func(func)[source]¶

Create a CustomJS instance from a Python function. The function is translated to Python using PyScript.
