breaking a Long JavaScript Line

[daneb]

Good day!

I'm sorry for posting a non-ASP question here but since my question is web-related, here it goes. There are times when you are writing your code in JavaScript and you need to break your code in the next line (especially if you're not using a text editor that doesn't automatically wrap lines). How do you do this in JavaScript? For instance, VB has the underscore character (_). Thanks in advance!

JavaScript follows the same syntax rules of C++ for the most part.

For instance, the following:

if( nCount > 15)
{
DoFunction( Argument1, Argument2, Argument3, Argument4 )
}

can be made into the following:

if( nCount > 15)
{
DoFunction( Argument1,
Argument2, Argument3, Argument4 )
}

The major rule you don't want to break is slittiing a string constant. The following:

alert( "This is a really long string that I might want to break up." );

can't legally be made into:

alert( "This is a really long string
that I might want to break up." );

Hope this helps. Send me more specific questions.

Thanks for the reply. I have tried your solution and it worked. However, for the second example you have cited, that is, breaking a string constant, I also found a solution. The concatenate operator (+) must be used.

For instance:
alert("I am a long string " +
"broken into two lines.")

Thanks again.

Excellent. That's one I haven't used yet.

Are there any, though, that you can't figure out?

Thanks for the concern. As of now, this is the only problem I have encountered. Maybe I'll post questions later as I continue to learn different Web technologies. This has been a great site. Keep up the good work, and thanks again!
