[Q] Check which object triggered JS callback

tniedermOct 11, 2016 #1

Hi,

I have multiple plots and a data table all based on the same source.

I have the following callback that opens a window only when a single point is selected.

Now I want that the window is only opened when the point is selected in the figure and not when it is selected in the data table.

Is there a way to check which object triggered the callback? Is there a documentation somewhere, where all JS relevant commands are described?

self.sources[i].callback = CustomJS(args=dict(p=p,source=self.sources[i]), code=“”"

var inds = cb_obj.get(‘selected’)[‘1d’].indices;

var d1 = cb_obj.get(‘data’);

var text = ‘’;

var datatext = ‘’;

if (inds.length == 1)

{

datatext = ('Point '+inds[0]);

var data = “
This is ‘myWindow’ for Point “+inds[0]+” : “+d1[‘Col X’][inds[0]]+”
”;

myWindow = window.open(“data:text/html,” + encodeURIComponent(data),

“_blank”, “width=200,height=100”);

myWindow.focus();

}

“”"

)

``

Thanks in advance and keep up the great work,

Tom

I would suggest you’re going to need to not attach the callback to
the source, but instead attach it to a Tap/Select Tool.

Because the cb_obj will always be the source in the case you're

describing.
