Question

I have a problem, I’m assigning a function to the onmouseout event, but after running the event, I need to remove it. would greatly appreciate your help.

Answer 1

This depends on your code, if you did this with d3, then you can say

inside your onmouseout event-function:

element.on("mouseout",func);

function func(){
    /*do your stuff*/
    element.on("mouseout",null);
}

If you bound the event via an event-attribute like <div onmouseout="..." > then you have to refactor this. In this case, simply use the d3 on() function to bind the event.

If you want to bind multiple handlers to the same event, you can use namespacing: By appending .name to the event, you can address them more specifically.
