获取checkbox中所有选中值及input后面所跟的文本；参考代码如下：<html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><title>js</title></head><script language="javascript">function aa(){var r=document.getElementsByName("r");for(var i=0;i<r.length;i++){if(r[i].checked){alert(r[i].value+","+r[i].nextSibling.nodeValue);}}}</script><body><form name="form1" method="post" action=""><input type="checkbox" name="r" value="1">a<br><input type="checkbox" name="r" value="2">b<br><input type="checkbox" name="r" value="3">c<br><input type="checkbox" name="r" value="4">d<br><input type="checkbox" name="r" value="5">e<br><input type="checkbox" name="r" value="6">f<br><input type="checkbox" name="r" value="7">g<br><input type="checkbox" name="r" value="8">h<br><input type="checkbox" name="r" value="9">i<br><input type="checkbox" name="r" value="10">j<br><br><input type="button" onclick="aa()" value="button"></form></body></html>
