请教一个正则正则表达式的问题

[postfix2]

var preg = /(<(select).*?(<\/select>))/gi;
我用上面这个正则表达式匹配字符串中的select控件，下面的字符串，只能匹配空的select控件，带有option值的不能匹配，请问这个正则表达式该怎么写呢？


"<table data-sort="sortDisabled"><tbody><tr class="firstRow"><td width="92" valign="middle" style="word-break: break-all;" align="right">标题</td><td valign="top" rowspan="1" colspan="3" width="849" style="word-break: break-all;"><p><br/></p><p><select name="==HGDW==" title="HGDW" leipiplugins="select" size="1" data-options="-1" id="HGDW" orgwidth="150" style="width: 150px;"></select></p></td></tr><tr><td width="92" valign="middle" style="word-break: break-all;" align="right">性别</td><td valign="top" rowspan="1" colspan="3" width="132" style="word-break: break-all;"><select name="==NGDW==" title="NGDW" leipiplugins="select" size="1" data-options="task_1516850618863" id="NGDW" orgwidth="150" style="width: 150px;"><option value="1">男</option></select></td></tr><tr><td width="92" valign="middle" style="word-break: break-all;" align="right"><br/></td><td valign="top" rowspan="1" colspan="3" width="132"><br/></td></tr></tbody></table>"

只能匹配空的select控件，有值的匹配不了。

可以匹配

s = `<table data-sort="sortDisabled"><tbody><tr class="firstRow"><td width="92" valign="middle" style="word-break: break-all;" align="right">标题</td><td valign="top" rowspan="1" colspan="3" width="849" style="word-break: break-all;"><p><br/></p><p><select name="==HGDW==" title="HGDW" leipiplugins="select" size="1" data-options="-1" id="HGDW" orgwidth="150" style="width: 150px;"></select></p></td></tr><tr><td width="92" valign="middle" style="word-break: break-all;" align="right">性别</td><td valign="top" rowspan="1" colspan="3" width="132" style="word-break: break-all;"><select name="==NGDW==" title="NGDW" leipiplugins="select" size="1" data-options="task_1516850618863" id="NGDW" orgwidth="150" style="width: 150px;"><option value="1">男</option></select></td></tr><tr><td width="92" valign="middle" style="word-break: break-all;" align="right"><br/></td><td valign="top" rowspan="1" colspan="3" width="132"><br/></td></tr></tbody></table>`
"<table data-sort="sortDisabled"><tbody><tr class="firstRow"><td width="92" valign="middle" style="word-break: break-all;" align="right">标题</td><td valign="top" rowspan="1" colspan="3" width="849" style="word-break: break-all;"><p><br/></p><p><select name="==HGDW==" title="HGDW" leipiplugins="select" size="1" data-options="-1" id="HGDW" orgwidth="150" style="width: 150px;"></select></p></td></tr><tr><td width="92" valign="middle" style="word-break: break-all;" align="right">性别</td><td valign="top" rowspan="1" colspan="3" width="132" style="word-break: break-all;"><select name="==NGDW==" title="NGDW" leipiplugins="select" size="1" data-options="task_1516850618863" id="NGDW" orgwidth="150" style="width: 150px;"><option value="1">男</option></select></td></tr><tr><td width="92" valign="middle" style="word-break: break-all;" align="right"><br/></td><td valign="top" rowspan="1" colspan="3" width="132"><br/></td></tr></tbody></table>"
s.match(/(<(select).*?(<\/select>))/gi)

另外要注意的是 . 不匹配换行符，如果匹配过程中有换行符就会匹配失败

没错，替换回车符问题完美解决，谢谢。

要匹配任意字符你可以改用 /(<(select)[\s\S]*?(<\/select>))/gi
