0 GatorV Posted March 12, 2005 Share Posted March 12, 2005 The basic sintax is condition ? val_if_true : val_if_false Translating the code you have is like: if( myVar.filters ) { var = "ie"; } else { if( myVar.style.MozOpacity == "string" ) { var = "mozilla"; } else { var = ""; } } Link to comment Share on other sites More sharing options...
0 FiREFLi Posted March 12, 2005 Author Share Posted March 12, 2005 if( myVar.filters ) { var = "ie"; } else { if( myVar.style.MozOpacity == "string" ) { var = "mozilla"; } else { var = ""; } } 585607389[/snapback] can that be shorted (yes, only slightly) to... if( myVar.filters ) { var = "ie"; } elseif( myVar.style.MozOpacity == "string" ) { var = "mozilla"; } else { var = ""; } } I thought I could skim some more code off, only got rid of about 3 chars :s Link to comment Share on other sites More sharing options...
0 +mrbester MVC Posted March 17, 2005 MVC Share Posted March 17, 2005 except that myVar.style.MozOpacity is unlikely to ever be "string" as you've left out the typeof: BTW var is a reserved word. So you can't use it as a variable name. var brow=''; if(myVar.filters){brow='ie';} if(typeof myVar.style.MozOpacity=='string'){brow='mozilla';} though if you're doing a browser detect between IE and Mozilla: var brow='',d=document; if(d.all){brow='ie';} elseif(d.getElementById){brow='mozilla';} this is because if such proprietary things as -moz-opacity become mainstream in CSS the typeof may fail as it won't necessarily be maintained as a property of style. Use W3C DOM standards and your code won't break somewhen down the line. Link to comment Share on other sites More sharing options...
Question
FiREFLi
If I'm not mistaken, this...
...is an alternative to a normally written if() {} else {} statement.
What is the normally written one? And if possible could someone explain how the ": ?" syntax works for this example.
Thank you! :)
