ASP去除img標籤style屬性只保留src

'功能:將IMG程式碼格式化為<img src="XXX" />格式,只保留SRC屬性，去掉IMG標籤的其他屬性。

Function FixImg(sString)

Dim sReallyDo,regEx,iReallyDo
Dim oMatches,cMatch
Dim tStartTime,tEndTime
If IsNull(sString) Then
FixImg = ""
Exit Function
End If
sReallyDo = sString
On Error Resume Next
sReallyDo = Replace(sReallyDo,vbCr," ")
sReallyDo = Replace(sReallyDo,vbLf,vbTab,"<img ",vbCrLf & "<img ",1,-1,1)
sReallyDo = Replace(sReallyDo,"/>"," />",1)
sReallyDo = ReplaceAll(sReallyDo,"= ","=",True)
sReallyDo = ReplaceAll(sReallyDo,"> ",">",True)
sReallyDo = Replace(sReallyDo,"><",">" & vbCrLf & "<")
sReallyDo = Trim(sReallyDo)
On Error GoTo 0
Set regEx = New RegExp
regEx.IgnoreCase = True
regEx.Global = True
'//去除onclick,onload等指令碼
regEx.Pattern = "\s[on].+?=([\""|\'])(.*?)\1"
sReallyDo = regEx.Replace(sReallyDo,"")
'//將SRC不帶引號的圖片地址加上引號
regEx.Pattern = "<img.*?\ssrc=([^\""\'\s][^\""\'\s>]*).*?>"
sReallyDo = regEx.Replace(sReallyDo,"<img src=""$1"" />")
'//正則匹配圖片SRC地址
regEx.Pattern = "<img.*?\ssrc=([\""\'])([^\""\']+?)\1.*?>"
sReallyDo = regEx.Replace(sReallyDo,"<img src=""$2"" />")
FixImg = sReallyDo
End Function

上面的程式碼確實寫得不錯，原理也可以參考下面的程式碼

js過濾img裡style屬性

var str = "<img style='ddddddddd'>"
str = str.replace(/<img[^>]*>/gi,function (match,capture) {
return match.replace(/style\s*?=\s*?([‘"])[\s\S]*?\1/ig,'')
}))
console.log(str)

不是替換直接通過js設定

var is=document.images;
for(var i=0,len=is.length;i<len;i++){
is[i].style.cssText=""
}
