使用正则表达式过滤多个相同的表情符号怎么做？
例如过滤： /::|/::|/::|

还有如果“/::|/::|/::|” 这些是变量呢？
求大神解救...

    var s = '/::|/::|/::|';
    s = s.replace(/[\{\}\|\^\$\\]/g, function (s) { return '\\' + s })
    var rx = new RegExp(s, 'g');
    s = 'abcde/::|/::|/::|sssaf/::|/::|/::|sfefa';

    s = s.replace(rx, '');
    alert(s)

其实我是想将 {'id':1,'phrase':'[惊讶]','url':'/::O'},{'id':2,'phrase':'[撇嘴]','url':'/::~'}, {'id':3,'phrase':'[色]','url':'/::B'},{'id':4,'phrase':'[发呆]','url':'/::|'}, {'id':5,'phrase':'[得意]','url':'/:8-)'},{'id':6,'phrase':'[害羞]','url':'/::$'}, {'id':7,'phrase':'[闭嘴]','url':'/::X'},{'id':8,'phrase':'[睡]','url':'/::Z'}, {'id':9,'phrase':'[大哭]','url':"/::'("},{'id':10,'phrase':'[尴尬]','url':'/::-|'}, {'id':11,'phrase':'[发怒]','url':'/::@'},{'id':12,'phrase':'[调皮]','url':'/::P'}, {'id':13,'phrase':'[呲牙]','url':'/::D'},{'id':14,'phrase':'[微笑]','url':'/::)'}, {'id':15,'phrase':'[难过]','url':'/::('},{'id':16,'phrase':'[酷]','url':'/::+'}, {'id':17,'phrase':'[抓狂]','url':'/::Q'},{'id':18,'phrase':'[吐]','url':'/::T'}, {'id':19,'phrase':'[偷笑]','url':'/:,@P'},{'id':20,'phrase':'[愉快]','url':'/:,@-D'}, {'id':21,'phrase':'[白眼]','url':'/::d'},{'id':22,'phrase':'[傲慢]','url':'/:,@o'}, {'id':23,'phrase':'[饥饿]','url':'/::g'},{'id':24,'phrase':'[困]','url':'/:|-)'}, {'id':25,'phrase':'[惊恐]','url':'/::!'},{'id':26,'phrase':'[流汗]','url':'/::L'}, {'id':27,'phrase':'[憨笑]','url':'/::>'},{'id':28,'phrase':'[悠闲]','url':'/::,@'}, {'id':29,'phrase':'[奋斗]','url':'/:,@f'},{'id':30,'phrase':'[疑问]','url':'/:?'}, {'id':31,'phrase':'[嘘]','url':'/:,@x'},{'id':32,'phrase':'[晕]','url':'/:,@@'}, {'id':33,'phrase':'[衰]','url':'/:,@!'},{'id':34,'phrase':'[骷髅]','url':'/:!!!'} 对应的url替换成<img src='image/'+id+'.gif' /> 用了你这个方法可以将一段字符串换替换一次，替换多次就不行了。[/quote] 你这个字符串不就是json格式的，eval生成json对象变量就好了

    var s = '/::|/::|/::|';
    s = s.replace(/[\{\}\(\)\|\^\$\\]/g, function (s) { return '\\' + s })
    var rx = new RegExp(s, 'g');
    s = 'abcde/::|/::|/::|sssaf/::|/::|/::|sfefa';

    s = s.replace(rx, '');
    alert(s)
