onclick

问题 Using the Python 3 "turtle" module, I am trying to handle two different click conditions separately: If a turtle is clicked on, it should call a function. (In the example below, it should switch from black to red, or vice versa.) If a click is NOT on a (visible) turtle, a different function should be called (to create a turtle at that point). Right now I can make this work using two different mouse buttons, like so: #!/usr/local/bin/python3 import turtle sc = turtle.Screen() def new_turtle(x,

问题 Hi I am trying to set up my react app such that when you click on a button in a row item in my react-table the data in that row is passed onto another component.

问题 I'm trying to have a SoundPool play while a view object is being clicked. I have successfully implemented it but found out that the sound of the click will lag.

You should better put params as var params = '{a:1,b:2}'; . Upd. As suggested in comments, another viable approach is using
