ASP去除img標(biāo)簽style屬性只保留src

"功能:將IMG代碼格式化為<img src="XXX" />格式,只保留SRC屬性，去掉IMG標(biāo)簽的其他屬性。

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, " ")
    sReallyDo = Replace(sReallyDo, vbTab, " ")
    sReallyDo = Replace(sReallyDo, "<img ", vbCrLf & "<img ", 1, -1, 1)
    sReallyDo = Replace(sReallyDo, "/>", " />", 1, -1, 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
    "http://去除onclick,onload等腳本
    regEx.Pattern = "\s[on].+?=([\""|\"])(.*?)\1"
    sReallyDo = regEx.Replace(sReallyDo, "")
    "http://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"" />")
    "http://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

上面的代碼確實寫得不錯，原理也可以參考下面的代碼

js過濾img里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(shè)置

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