摘要：暂无

客户要求保存原有的img已在的属性,郁闷,继续改

代码如下:

function shownew(content,ntype)

shownew = ""

if(ntype = 1) then

shownew = shownew &" <TABLE width=100% >"
shownew = shownew &"<TR>"
shownew = shownew &" <TD width=700 align=center style='word-break:break-all' valign=top>"&ShowPic(content)&"</TD>"
shownew = shownew &"</TR>"
shownew = shownew &"<TR>"
shownew = shownew &" <TD valign=top style='word-break:break-all'>"&OnlyWord(content)&"</TD>"
shownew = shownew &"</TR>"
shownew = shownew &"</TABLE>"

elseif (ntype = 2) then

shownew = shownew &" <TABLE width='100%'>"

shownew = shownew &"<TR>"
shownew = shownew &" <TD style='word-break:break-all' valign=top>"&OnlyWord(content)&"</TD>"
shownew = shownew &"</TR>"
shownew = shownew &"<TR>"
shownew = shownew &" <TD align=center width=700 valign=top style='word-break:break-all'>"&ShowPic(content)&"</TD>"
shownew = shownew &"</TR>"
shownew = shownew &"</TABLE>"

elseif (ntype = 3) then

shownew = shownew &"<TABLE>"

shownew = shownew &"<TR>"
shownew = shownew &"<TD width=100 align=center valign=top>"&ShowPic(content)&"</TD>"

shownew = shownew &"<TD width=80% style='word-break:break-all' valign=top>"&OnlyWord(content)&"</TD>"

shownew = shownew &"</TR>"
shownew = shownew &"</TABLE>"

elseif (ntype = 4) then

shownew = shownew &"<TABLE>"

shownew = shownew &"<TR>"

shownew = shownew &"<TD width=80% valign=top style='word-break:break-all'>"&OnlyWord(content)&"</TD>"
shownew = shownew &"<TD width=100 valign=top align=center>"&ShowPic(content)&"</TD>"

shownew = shownew &"</TR>"
shownew = shownew &"</TABLE>"
else
shownew = shownew &content
end if

end function

'显示提取的图片
function ShowPic(strng)

set regEx2 = new RegExp

regEx2.Pattern = "(src=)('|"&CHR(34)&"| )?(.[^'| |"&CHR(34)&"]*)(\.)(jpg|gif|png|bmp|jpeg)('|"&CHR(34)&"| |>)?" '设置模式。

Set Matches2 = regEx2.Execute(ImageUrls(i)) '执行搜索。

For Each Match2 in Matches2 '遍历匹配集合。

'全Img标签
newpic = LCase(ImageUrls(i))

'如果没有自定义BORDER增加BOrder=0,其它原属性保留

if(instr(newpic,"border")=false) then newpic = left(newpic,len(newpic)-1) + " border='0' >"
if(instr(newpic,"width")=false) then newpic = left(newpic,len(newpic)-1) + " width='200' >"

newpic = "<a style='padding:20px' href='"&Match2.SubMatches(2)&Match2.SubMatches(3)&Match2.SubMatches(4)&"' >"& newpic & "</a>"

ShowPic = ShowPic & newpic
Next

Set regEx2 = nothing
end function

End Function
