屏蔽敏感词的正则表达式

/(?!.*\[徽\]\[信\]|.*紸 微|.*互动逡|.*qun|.*v辛|.*v信|.*v欣|.*羣|.*裙|.*企业裙|.*亻言|.*微信)^.*$/ig.test('微信')

javascript版本，如需其他版本，自行转换

var newword = '微信';
var sourceWords = '[徽][信]|紸 微|互动逡|qun|v辛|v信|v欣|羣|裙|企业裙|亻言';
txtWords = filterRegex(sourceWords);
var words = txtWords.split('|');
for (i = 0, len = words.length; i < len; i++) {
    words[i] = ".*" + words[i];
}
var pattern = "(?!" +
    words.join("|") +
    ")^.*$";
var js = "/" + pattern + "/ig.test('" + newword + "')";
console.log(js);
if (eval(js)) {
    //不存在敏感词
} else {
    //存在敏感词

// 过滤正则表达式保留字符
