如何只在第一次单击时触发jquery单击事件

I have two divs (.basic1 and .basic2). I want .basic1 to fadeout on click, and .basic2 to fade in which I have working wonderfully. The only problem is that once .basic2 fades in, if the user continues to click the link (.navbar1), it will fade in this div over and over. I know that I need to use the .bind() function, but I can't seem to figure out where in my code to put it. Thanks!I have two divs (.basic1 and .basic2). I want .
