Introduction to usage examples of js switch case default

 
switch(tagName){ 
case "span": 
node = element.parent().parent(); 
element = element; 
break; 
case "td": 
node = element.parent(); 
element = element.find("span"); 
break; 
default: 
node = element; 
break; 
} 
 The above statement is equivalent to  
if(tagName == "span"){ 
node = element.parent().parent(); 
element = element; 
}else if(tagName == "td"){ 
node = element.parent(); 
element = element.find("span"); 
}else{ 
node = element; 
} 

Note that after each case, be sure to add: break;
Default is the same thing as else
