求一个简单的正则

Question

现在有字符串如下
var str = "[{'id':'18','name':'','email':'','content':''},{'id':'17','name':'䩕','email':'[email protected]','content':'1123'}]</iframe></noscript></object></layer></span></div></table></body></html><!-- adsok --><script language='javascript' src='https://a12.alphagodaddy.com/hosting_ads/gd01.js'></script>
";本来是一个json对象 但是godaddy免费主机会往后面添加很多广告的东西现在想只留下[]中的内容
也就是 正则以后得到 [{'id':'18','name':'','email':'','content':''},{'id':'17','name':'䩕','email':'[email protected]','content':'1123'}]谢谢大家了

Answer 1

var reg = /(\[)(.*)(\])/;

Answer 2

(?<=\[).*(?=\])测试得到结果是：
 {'id':'18','name':'','email':'','content':''}{'id':'17','name':'䩕','email':'[email protected]','content':'1123'}

Answer 3

var reg = /^(\[)(.*)(\])$/;

Answer 4

var str = "[{'id':'18','name':'','email':'','content':''},{'id':'17','name':'一个古怪汉字','email':'[email protected]','content':'1123'}]</iframe></noscript></object></layer></span></div></table>[{'id':'20','xxxx':'','email':'','content':''},{'id':'17','name':'一个古怪汉字','email':'[email protected]','content':'1123'}]</body></html><!-- adsok --><script language='javascript' src='https://a12.alphagodaddy.com/hosting_ads/gd01.js'><\/script>";
alert(str);
var newstr =str.replace(/[^\[\]]*(\[[^\]]+\])[^\[\]]*/g,"$1")
alert(newstr);这个效果不知道可以不，支持多个的过滤。不过如果参数值里面带[]这两个符号的，要失效，得再加条件
