jquery implementation Click on multiple labels background color change, click the color change to restore the original colors

The key code is as follows:

 $(function(){

                 $( "div" ).toggle(function(){     //这儿传入html标签div，也可传入类或者ID，使用了toggle（）方法，不懂得同学去百度自行补习                      $( this ).css( "backgroundColor" , "red" );  //这儿是点击一次后改变成红色                  },function(){          //千万不要忘记此处的 ， 否则会报错                      $( this ).css( "backgroundColor" , "blue" ); //这儿是点击一次后改变成蓝色                  });              })
