问题 I used Jquery to control the Css styles of svg image dynamically in Angular 2. 1: Control using events like mouse hover Below is a sample code for a simple circle .svg image with initial styles defined and a mouseover event on circle which will trigger 'func1' on hovering the circle: <svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 175.7 177" style="enable-background:new 0 0 175.7 177;" xml:space=

问题 In the below code I am trying to loop three functions that only fire once the previous function is complete, with the last function then calling the first to start the process all over again.
