求一个正则表达式的模式字符串,匹配下列字符串
href="http://www.csdn.net/abc.jpg"
就是匹配以href=开头,.jpg或者.gif,.bmp,.png等图片扩展名结束的字符
但是下面的情况不可以匹配:
href=imageView.asp?abc.jpg,就是说字符中含有.asp,.php,.jsp等不匹配
具体来说就是一个html格式的字符串,里面有一些链接点击后显示图片,现在要把这些链接替换成ASP页面(imageView.asp),然后页面中显示图片,图片的url用imageView.asp?url=abc.jpg这样的参数传递到imageView.asp
'===================================================
'函数名：replaceImageView
'作 用：把图片链接替换成网页链接,网页中显示图片
'参 数：strContent ----------- 要替换的html字符串
'===================================================
function replaceImageView( strContent )
Set re = new RegExp
re.IgnoreCase = True
re.Global = True
re.Pattern = "(href=)(S*)((\w)+[.]{1}(jpg|jpeg|gif|bmp|png))"
Set imageLink = re.Execute( strContent )
i = 1
for each imageLinkUrl in imageLink
tempUrl = Replace( imageLinkUrl, "href=", "")
tempUrl = Replace( tempUrl, """", "" )
strContent = Replace( strContent, tempUrl, "imageView.asp?url="+tempUrl )
next
replaceImageView = strContent
end function
a = a.replace(/(^[\s]*)|([\s]*$)/g, "");
