How to use selector (queries) inside BokehJS

Community Support
1

I am trying to retrieve all elements containing specific tag:

I tried the following 3 options

CustomJS(args=dict(rootDom=rootDom), code="""

 console.log(rootDom);

 //var found = rootDom.select("tags", "myColumn");
 //var found = rootDom.select({"tags", "myColumn"});
 //var found = rootDom.select({type: "tags", name: "myColumn"});

 console.log(found);

 """)

The first one works, but returns empty array. Others return exceptions “Invalid selector”.

The following code works properly on Python side:

elems = rootDom.select({"tags": 'myColumn'})

Thanks!

Tags are just arbitrary metadata that can be attached for searching the Python object graph. They are not related to dom selectors

This is exactly what I am willing to do - find object by arbitrary metadata, but on JS side.

Thanks

I am trying to attach new classes by settings special tags on elements and than using JS to search for those tags and insert classes in tagged elements.

I am also missing a way to trigger BokehJS callback when HTML created…
