我要评论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, 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=""$1"" />") '//正则匹配图片src地址 regex.pattern = "<img.*?\ssrc=([\""\'])([^\""\']+?)\1.*?>" sreallydo = regex.replace(sreallydo, "<img src=""$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 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=""
}
