I have recently started using Ajax in my .Net MVC project. I using a Empty Thumbs up Bootstrap Icon and I am trying to chnage the icon to Thumbs-up-fill when user clicks on it. My Like count is working fine with ajax but i am unable to change the d value in path of the svg for the icon. To change the icon to the filled one, i just need to change the d value in path. But due to some reason, I am unable to change it when inspected. Kindly help me on this one.
