该<script> tag doesn't seem to work in bokeh Div

Question

I'm using bokeh to draw some interactive plots, and I also wanna add some html div as description for the plot. Part of my code:

from bokeh.io import show
from bokeh.layouts import widgetbox
from bokeh.models.widgets import Div
div = Div(text="""<p>Title</p><script type="text/javascript">document.write("hi")</script>""")
show(widgetbox(div))

I excepted the output would be:

Title
hi

But I only got:

Title

Could someone please help me?

This is not possible. Bokeh Div objects only set innerHTML with the text given, as-is. In order to have a script execute, additional work must happen. See, for instance, the answers to Executing <script> elements inserted with .innerHTML . Bokeh is extensible, so it is possible you could create a Custom Extension that does the required extra work to cause scripts to be evaluated.

Alternatively if you embed your Bokeh document in a custom template, you could put the script in template.
