下面的代码是从html中正则取出图片,
Function getphoto(strHTML)
Dim objRegExp, Match, Matches
Set objRegExp = New Regexp
objRegExp.IgnoreCase = True
objRegExp.Global = True
objRegExp.Pattern = "<img.+?>"
tp=""
Set Matches = objRegExp.Execute(strHTML)
For Each Match in Matches
tp=tp & Match.value
exit for
Next
getphoto=tp
Set objRegExp = Nothing
End Function
下面的代码时进行图片按比例缩放
function ResizeImage(imageid,limitWidth,limitHeight)
{
var image = new Image();
image.src = imageid.src;
if(image.width <= 0 && image.height <= 0) return;
if(image.width/image.height >= limitWidth/limitHeight)
{
if(image.width > limitWidth)
{
imageid.width = limitWidth;
imageid.height = (image.height*limitWidth)/image.width;
}
}
else if(image.height > limitHeight)
{
imageid.height = limitHeight;
imageid.width = (image.width*limitHeight)/image.height;
}
if (imageid.parentElement.tagName != "A")
{
imageid.onclick = function(){window.open(this.src);}
imageid.style.cursor = "hand";
}
}
window.onload = InitImages;
function InitImages()
{
//图片的约束宽度和高度
var maxWidth = 100;
var maxHeight = 100;
var imgs = document.getElementsByTagName("img");
for(var i=0; i < imgs.length; i++)
{
var img = imgs;
if(img.width>maxWidth||img.height>maxHeight)
ResizeImage(img, maxWidth, maxHeight);
}
}
