js正则匹配符号中间

"tag":"0","hpmax":"330","actortype":"1"
"tag":"1","hpmax":"340","actortype":"1"
"tag":"2","hpmax":"350","actortype":"1"
"tag":"3","hpmax":"360","actortype":"1"
"tag":"4","hpmax":"370","actortype":"1"
如上面一组数据，我想匹配到330 340 350 360 370
求教

按照你的要求编写的Javascript语言的匹配符号中间数据的程序如下<br>&lt;script type=text/javascript&gt;<br> var str='&quot;tag&quot;:&quot;0&quot;,&quot;hpmax&quot;:&quot;330&quot;,&quot;actortype&quot;:&quot;1&quot;\r\n&quot;tag&quot;:&quot;1&quot;,&quot;hpmax&quot;:&quot;340&quot;,&quot;actortype&quot;:&quot;1&quot;\r\n&quot;tag&quot;:&quot;2&quot;,&quot;hpmax&quot;:&quot;350&quot;,&quot;actortype&quot;:&quot;1&quot;\r\n&quot;tag&quot;:&quot;3&quot;,&quot;hpmax&quot;:&quot;360&quot;,&quot;actortype&quot;:&quot;1&quot;\r\n&quot;tag&quot;:&quot;4&quot;,&quot;hpmax&quot;:&quot;370&quot;,&quot;actortype&quot;:&quot;1&quot;';<br> var regex=/&quot;hpmax&quot;\:&quot;([0-9]+)&quot;/ig;<br> var result;<br> while((result=regex.exec(str))!=null)<br>  alert(result[1]);<br>&lt;/script&gt;<br><br>运行结果<br>330<br>340<br>350<br>360<br>370
