Question:

How to fix Uncaught ReferenceError in python?

The error message "Uncaught ReferenceError: (your function) is not defined" typically occurs in JavaScript when you're trying to use a function or variable that hasn't been declared or defined before it is called. Here are some common reasons why this error might occur:

Typo or misspelling: Check for typos or misspellings in the function name. Make sure the function name is consistent where it is defined and where it is called.
Function not loaded: If the function is defined in a separate file or script, ensure that the script containing the function is loaded before the script that calls the function. The order of script tags in your HTML file matters.
Scope issues: Check the scope of your function. If it's declared inside a block (such as an if statement or a loop), make sure you are trying to call it from within the same scope.
Check the file paths: If your JavaScript code is in external files, ensure that the file paths are correct and the files are properly linked.
Check for asynchronous code: If you're using asynchronous code, ensure that the function is defined before the asynchronous operation is complete.

Here we want to implement a feature that excludes all markers except the one clicked with the 'Detail' button among the approximately 8 folium markers.

For this we have to remove the <script> tags from js_definition and use m.get_root().script instead of m.get_root().html.

def createFoliumMap(self):

coordinate = (36.1908784, 127.1577341)

m = folium.Map(title='map',

zoom_start=8,

location=coordinate,

width='100%',

height='100%')

# remove '<script>' tags

js_definition = """

function removeOtherMarkers(map, clickedMarker) {

var allMarkers = map._layers;
