<script type="text/javascript"> var lastname=document.getElementsByName("fangchan"); //!!!!!!!!定义的全局变量,然后在下面的用document.write(lastname.className);测试不行啊 //lastname是object nodelist 不是object HTMLElement function hidetext(obj) { var myname = obj.parentNode; var mynamevalue = myname.getAttribute("name"); var content = document.getElementById("content"); var mycontent = content.childNodes; for(var m=0; m< mycontent.length;m++) { if(!(mycontent[m].nodeType==3 && !/\S/.test(mycontent[m].nodeValue))){ var myidvalue=mycontent[m].getAttribute("id"); if(myidvalue==mynamevalue){ mycontent[m].style.display="block"; myname.className="on"; if(lastname!=myname) //判断为了重复点击同一个不会把它的样式消掉 { lastname.className=""; lastname=myname; } } else mycontent[m].style.display= "none"; } else continue; } } </script>
