ASP删除img标签的style属性只保留src的正则函数

做手机网站的时候图片要做自适应，由于手机网站跟PC网站共用1个数据库，导致文章内的图片有部分带有：style=""等属性，导致手机端图片width:100%失效，去掉mg标签style属性只保留src即可解决问题

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="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, iReallyDoDim oMatches, cMatchDim tStartTime, tEndTimeIf IsNull(sString) ThenFixImg = ""Exit FunctionEnd IfsReallyDo = sStringOn Error Resume NextsReallyDo = 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 0Set regEx = New RegExpregEx.IgnoreCase = TrueregEx.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=""$1"" />")'//正则匹配图片SRC地址regEx.Pattern = "<img.*?ssrc=([""'])([^""']+?)1.*?>"sReallyDo = regEx.Replace(sReallyDo, "<img src=""$2"" />")FixImg = sReallyDoEnd 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 style='ddddddddd'>"str = str.replace(/<img[^>]*>/gi, function (match, capture) {return match.replace(/styles*?=s*?([‘"])[sS]*?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=""}
