Re: [Dynapi-Help] problem with toloadlayer fixed

[Jordi - IlMaestro - Ministral]

Here's some code I used to fix Netscape not applying bgcolor and bgimages of
external content. The method returns and object with bgColor and bgImage
properties set to the appropiate values, so you can manually apply them. Notice
that this won't work for loaded pages, only setHTMLs, because you need the HTML
string to parse it.

A user pointed me that if the content was complex ( lots of nested tags ) IEs
performance slowed down up one minute. This can be fixed if you first do a
string.indexOf(<body'>) and give only a piece of the HTML to the function.



// This is some Regular Expressionism that allows to extract the body bgcolor
and
// body bgImage tags of a content string, so after the content has been set the
layer
// is given the appropiate bgcolor and bgImage, if any specified.

IbsScrollBgColorTagRegExp =
/.*<[\s]*body.*[\s]bgcolor[\s]*=[\s]*['|"]?[\s]*(#?\w*)['|"|\s|>].*/i
IbsScrollBgImageTagRegExp =
/.*<[\s]*body.*[\s]background[\s]*=[\s]*['|"]?[\s]*([\.\w]*)['|"|\s|>].*/i

function getBgTags(h) {
 var r = new Object()
 m = IbsScrollBgColorTagRegExp.exec(h)
 if(m && m[1]) r.bgColor = m[1]; else r.bgColor = 'white'
 m = IbsScrollBgImageTagRegExp.exec(h)
 if(m && m[1]) r.bgImage = m[1]; else r.bgImage = 'n'
 return r
}
