为什么Jquery .click（）会触发多个函数？

I've been making a game to practice programming, and I am having trouble using the Jquery .click() function. I have two buttons in my code, the start button and the attack button. When I click the start button, the .click() function fires the code for the other button as well, which causes my main menu to freeze up and not draw the game screen. I've used separate id's for the buttons, but they both seem to recognize the click on the start button. I can't get it to work in JSFiddle, but all the code is there. Can someone please tell me how to use multiple buttons?I've been making a game to practice programming
