ASP删除img标签的style属性只保留src的正则函数

ASP去除img标签style属性只保留src

'功能:将IMG代码格式化为<img src="https://www.jb51.net/article/XXX" />格式,只保留SRC属性,去掉IMG标签的其他属性。

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     '//去除onclick,onload等脚本     regEx.Pattern = "\s[on].+?=([\""|\'])(.*?)\1"     sReallyDo = regEx.Replace(sReallyDo, "")     '//将SRC不带引号的图片地址加上引号     regEx.Pattern = "<img.*?\ssrc=([^\""\'\s][^\""\'\s>]*).*?>"     sReallyDo = regEx.Replace(sReallyDo, "<img src=""https://www.jb51.net/article/$1"" />")     '//正则匹配图片SRC地址     regEx.Pattern = "<img.*?\ssrc=([\""\'])([^\""\']+?)\1.*?>"     sReallyDo = regEx.Replace(sReallyDo, "<img src=""https://www.jb51.net/article/$2"" />")     FixImg = sReallyDo End Function

上面的代码确实写得不错,原理也可以参考下面的代码

js过滤img里style属性

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

不是替换直接通过js设置

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